| Welcome The Nano-X Window System is an Open Source project aimed at bringing the features of modern graphical windowing environments to smaller devices and platforms. Nano-X allows applications to be built and tested on the Linux desktop, as well as cross-compiled for the target device. The Nano-X Window System was previously named Microwindows, but has been renamed due to conflicts with Microsoft's Windows trademark. There are two APIs implemented in the system, a Win32 API and an Xlib-like API. Please read the FAQ for more information. An extensive Architecture document is also available. Check out the Articles that have been written about Microwindows in the left sidebar. To get involved, please join the Nano-X mailing list. There is a full mirror of the mailing list accessible here. News The Microwindows Project renamed to The Nano-X Window System January 30, 2005
The project has been renamed to The Nano-X Window System, due to conflicts with the Windows trademark registered by Microsoft. Although the web site has not been updated for some time, updates are in the works. The CVS source release will be packaged and released as v0.91 shortly. Quite a few enhancements and patches have been received, which will be released as v0.92. NXLIB v0.44 - Nano-X / Xlib Compatibility Library June 1, 2003
The first public release of the NXLIB Project, a companion project to Microwindows that allows X11 binaries to run unmodified using the Microwindows Nano-X server, is available from the Microwindows web site:
ftp://microwindows.censoft.com/pub/microwindows/nxlib-0.44.tar.gz This release has been tested heavily with FLTK v1.0.11, and FLTK v1.1.3. FLTK is built using the standard X11 headers and libX11.so shared library. The NXLIB replacement for libX11.so (named libX11.so.6) is then used to run all FLTK test programs successfully without source or binary modification. This is great news since we now can use a very full-featured small footprint widget set, as well as many already-built applications in the Microwindows environment.
Although a work in progress, NXLIB also is making progress running unmodified QT and GTK+ programs. NXLIB v0.44 has been tested with QT v2.3.1, and GTK+ 1.2.10, and many of the demonstration programs are currently running.
NXLIB works by emulating only the Xlib (libX11.so) library. Since FLTK's use of Xlib is much smaller than GTK+ or QT, more programs are currently running. There is still work to do with the Xrm resource manager routines, and of course the idea is to keep the footprint small.
NXLIB requires Microwindows v0.90, just released.
The Microwindows mailing list, at microwindows.org will be used for questions, suggestions and patches to NXLIB. NXLIB is licensed under a the MPL license, with a conversion capability to GPL, the same as Microwindows.
Have fun! - Greg
Version 0.90 release, many font enhancements, standard calibration May 31, 2003
Microwindows version 0.90 is released, and available on the website:
ftp://microwindows.censoft.com/pub/microwindows/microwindows-0.90.tar.gz
ftp://microwindows.censoft.com/pub/microwindows/microwindows-fonts-0.90.tar.gz
There have been many additions, enhancements and bugfixes since the November 0.89 release. Following are some of the major highlights:
o Support for the new NXLIB project, which allows X11 binaries to run unmodified on Microwindows, without requiring the X11 server.
o Support for Sharp Zaurus, Tuxscreen, TriMedia, and Cygnus X11 platforms.
o Standardized calibration (nxcal) support now built into Microwindows. A single touchscreen driver supporting popular ARM platforms including iPAQ, Zaurus, ADS and Tuxscreen is also available.
o Many font enhancements, including support for FreeType 2, as well as a new BDF font converter that will allow any BDF font, including large Asian fonts, to be used. In addition, a new .fnt native binary font format is supported. DBCS multibyte decoding is supported for Japanese, Chinese, and Korean encodings (BIG5, GB2312, EUCCN, EUCKR, EUCJP, JISX0213)
o Major speed improvements to the X11 screen driver as well as text drawing.
o Per-color alpha support with a new 32bit ARGB hardware driver is included.
o LIRC keyboard with HAVI keyboard mappings.
o Doxygen-based automated documentation generated from source code for html and pdf docs.
o And lots more! New APIs
GrGrabKey, GrUngrabKey
GrCreateFontFromBuffer, GrCopyFont
GrSetTransform, GrCalcTransform, GrSaveTransform
GrSetForegroundPixelVal, GrSetBackgroundPixelVal

Enabled lots of warnings for GCC.
(src/Arch.rules, src/Makefile.rules):
Tidying: Moved defines, libraries and compiler flags into these two
files.
Tidying: Simplified the layout, so libraries and headers for a
specific config option are together (before they were separated).
Tidying: Simplified how libraries are handled - now they only need to be
added to one variable, rather than five.
Bugfix: Corrected a few options that were added to CFLAGS rather than
DEFINES or INCLUDES.
(src/*/Makefile [but not src/demos/*]):
Tidying: Removing options that were moved into Makefile.rules
Tidying: Removing the (now empty) compiler flags section of these
Makefiles.
(src/fonts/*/Makefile):
Tidying: Removing these Makefiles that did nothing.
* added minormakefixes.diff: (Jonathan)

Bugfix: Display a fatal error if the specified filename is longer
than the fixed-sized filename buffer, instead of crashing.
Bugfix: Make the fixed-size filename buffer longer.
Feature: Add -o option to specify the output file name.
(Previously it always computed this from the input file name.
The old behaviour still applies if you do not specify -o)
(src/Makefile.rules):
Bugfix: Don't redirect output of convbmp, it doesn't produce
output on standard out (even before my modifications).
Use the -o option to specify the output file.
Bugfix: "make clean" would delete all files in src/ if the
bin/ directory did not exist.

use MWFONT_SYSTEM_VAR instead
- original MWFONT_SYSTEM_VAR and MWFONT_OEM_FIXED removed
- deprecated MWFONT_GUI_VAR (redirected to MWFONT_SYSTEM_VAR)
- deprecated MWFONT_OEM_FIXED (redirected to MWFONT_SYSTEM_FIXED)

* re-inserted special hack for portait mode pixmap handling in genmem.c
* added auto UC16 conversion to handle large (non-ASCII) bdf fonts
- requires loading converted bdf file as .fnt file
- any BDF can now be used to display international chars
convert font using fonts/convbdf.c: "convbdf -f *.bdf"
- MWTF_DBCS_* flags can be used with font for DBCS encoding
- this is the new preferred method for Chinese,Japanese & Korean
* speed up PCF font output for ASCII fonts

MWTF_DBCS_EUCJP, MWTF_DBCS_JIS: must use w/GrText for builtin fonts
- "count" parameter with dbcs is byte-length of dbcs string
- can use MWTF_DBCS_* flags with any (UC16-indexed) fonts now
- can use multiple DBCS encodings and fonts at same time
- can use DBCS encoding with non-compiled-in fonts, encoding is
seperate from specially-compiled-in fonts.
* fixed BIG5, GB2312, JISX0213, KSC5601 from previous GetTextBits retmap change
Version 0.89pl10 - 04 Apr 2003 - greg@censoft.com

case in GdBitmap and corefont_textdraw. Also clear
background once not per char. Changed GetTextBits
driver entry point to not copy font data. 60% improvment (Aaron)

Version 0.89pl7 - 24 Feb 2003 - greg@censoft.com
* APPLIED mw_phillips_fontnetworkbug.diff (Jonathan)
Contributed by Koninklijke Philips Electronics N.V.
* Added GrCreateLogFont nxRequest.
* Removing the hardcoded 64-character limit on font names.
This caused problems with FreeType 2, because the font names
are just filenames. The network layer no longer
restricts font name length, but there is still a
potential buffer overflow in devfont.c.
* APPLIED mw_phillips_freetype2.diff (Jonathan)
Contributed by Koninklijke Philips Electronics N.V.
* Added FreeType 2 support, HAVE_FREETYPE_2_SUPPORT in config
* APPLIED mw_phillips_drawarea.diff (Jonathan)
Contributed by Koninklijke Philips Electronics N.V.
* Added new DrawArea blitters. Controlled by the defines
MW_FEATURE_PSDOP_COPY, MW_FEATURE_PSDOP_ALPHAMAP,
MW_FEATURE_PSDOP_ALPHACOL,
MW_FEATURE_PSDOP_BITMAP_BYTES_LSB_FIRST, and
MW_FEATURE_PSDOP_BITMAP_BYTES_MSB_FIRST in device.h.
Usually called through GdDrawAreaInternal() in devdraw.c.
* fixed nxroach GrArea alpha bug (BLACK used in GrArea crash)
* APPLIED mw_phillips_alpha.diff (Jonathan)
Contributed by Koninklijke Philips Electronics N.V.
* Adds 8-bit alpha value to MWCOLORVAL value, new fblin32alpha.c
* Added MWPF_TRUECOLOR8888 pixel type.
* Adding MWIMAGE_ALPHA_CHANNEL flag.
* Changes to GdDrawImage() to simplify, fix a
24bpp bug, and to add the MWIMAGE_ALPHA_CHANNEL flag.
* Adding MWROP_USE_GC_MODE option to GrCopyArea
* Adding a default implementation to fb.h for the new Porter-Duff
blending rules, which assumes that both SRC and DST have
alpha=1.0. Drivers that actually support alpha should not
use these macros in Porter-Duff modes.
* MWMODE_XOR_FGBG implementation
* Adding Porter-Duff MWMODE and MWROP codes,
renumbering some existing MWROP codes to prevent collisions.
Adding MWMODE_XOR_FGBG and MWROP_XOR_FGBG
* Adding MWMODE_TO_ROP() macro.
* Adding code to choose between 8/8/8/8 and 0/8/8/8
modes on 32-bit displays, depending on whether or not the
display claims to support alpha.
* New 32-bit with alpha driver: fblin32alpha.c.
* Adding GR_ARGB() - just calls MWARGB().
* Rewriting MWRGB() to set the alpha to 255 (opaque).
* Adding MWARGB() macro
* Use new GrSetGCForegroundPixelVal() API rather than the
deprecated MWPALINDEX() macro.
*** NON-BACKWARDS-COMPATIBLE API CHANGE: ***
Removing MWF_PALINDEX and MWPALINDEX(). They don't work
due to the alpha blending changes. Clients should be
modified to use GrSetGCForegroundPixelVal(index) instead
of GrSetGCForeground(MWPALINDEX(index)), and similarly to use
GrSetGCBackgroundPixelVal() to set the background color.
* APPLIED mw_phillips_color.diff (Jonathan)
Contributed by Koninklijke Philips Electronics N.V.
* API changes to allow later alpha patch.
* Added GrSetGCForegroundPixelVal, GrSetGCBackgroundPixelVal
* Added new functions GdSetForegroundColor() and GdSetBackgroundColor
GdSetForeground/GdSetBackground now takes MWPIXELVAL only.
* Added fgispixelval and bgispixelval flags to GR_GC and GR_GC_INFO.
* Added a PSD parameter to GdSetForeground() and GdSetBackground(),
GdFindColor(). Allows multiple color depths to be supported
at the same time by different PSDs
* (wingdi.c) Using GdGetColorRGB() instead of a switch()
statement that duplicated it's functionality.
* Replacing GdSetForeground(GdFindColor(c))
with GdSetForegroundColor(psd,c) - note the extra PSD
parameter. Similarly for GdSetBackgroundColor().
* New function GdGetColorRGB(), the inverse of GdFindColor().
* Preventing multiple arc draws - this was causing
problems in XOR and alpha-blending drawing modes.
* APPLIED mw_phillips_x11.diff (Jonathan)
Contributed by Koninklijke Philips Electronics N.V.
* Major speed enhancements to X11 screen driver.
* Resizing the window caused an assert() fail and
crash. Added a call to set size hints on the window, indicating
it's not resizable.
* Handle true color X modes correctly. The previous
code made the assumption that a X always lays out it's colors
in exactly the same way as MicroWindows. This is incorrect.
For example, some Microsoft Windows based X servers use BGR
rather than RGB ordering.
* If we are in true color mode, then we try hard to
get a true color X window if the server can support it. This
is a huge speed boost with a 32-bit Nano-X app, properly
antialiased fonts (so we use lots of colors) and an old 8-bit
palettised display. (In 3/3/2 RGB mode we can compute color
values easily. In 8-bit palettised mode we have to do a very
expensive lookup).
* An alternative blit implementation. Since we are
maintaining a separate off-screen copy of the display, we
perform all blits on this copy, then simply copy the offscreen
data onto the screen. The only exception are simple copies (no
raster ops) between parts of the screen - these are handled by
the server to save us having to send an image across the
connection.
* Added PIXEL332RED8 and PIXEL332RED32 macros to device.h
* APPLIED mw_phillips_1.diff (Jonathan)
Contributed by Koninklijke Philips Electronics N.V.
* Misc build system changes.
* Added .cvsignore for CVS
* Initial support for the TriMedia media processor. Not complete.
* Added INSTALL_USER, INSTALL_GROUP, and INSTALL_GROUP_2 options.
* Correcting install target so that libraries
are writable by the user who owns the file.
* Rewriting subdirs target so that the build stops on error.
* added config option HAVETEXTMODE, removed from scr_fb.c
* Added config option GPROF=Y for profiling support.
* Added config option BIGENDIAN=Y/N, may define MW_CPU_BIG_ENDIAN to 1.
* Added various echo statements to demo and nanox link steps
* (demos/nanox/Makefile) Only compiling the snap_jpg demo if we
have framebuffer support.
* Fixing a compiler warning in scr_x11.c
* Removing compiler warning about unused variable 'tty'
if HAVETEXTMODE is disabled.
* Commented out XSynchronize() in scr_x11.c (way slow)
(08 Dec 02)
* fix GrCheckNextEvent return no event for X11/LINK_APP_TO_SERVER case
* changed pcf debug output, firstchar calculation, count calc
* corrected include files for RH 7.x

Have fun! - Greg Mozilla, SDL, SMPEG, Rdesktop supported with 0.89pre8 November 15, 2001
Microwindows version 0.89pre8 is released and available at:
ftp://microwindows.org/pub/microwindows/microwindows-0.89pre8.tar.gz A very large number of enhancements are included in this pre-release. The code base is stable, and is being used in a variety of other open source projects, including the Mozilla web browser, SMPEG digital video viewer, SDL gaming/direct video library, rdesktop RDP Windows thin client, and the PIXIL operating environment. The plan is to release final version 0.89 after a several week comment period for last-minute bugfixes and changes. Following is a list of additional available software compatible with this release: ftp://microwindows.org/pub/microwindows/sdl113c.tgz - SDL v1.1.3
ftp://microwindows.org/pub/microwindows/smpeg040c.tgz - SMPEG v0.4.0
http://rdesktop-nanox.tuxia.org/rwin-nanox-1.5.0.tar.gz - rdesktop v1.5.0
http://ftp.mozilla.org/pub/mozilla/releases/mozilla0.9.4/src/mozilla-source-0.9.4.tar.bz2 - Mozilla v0.9.4
http://embedded.centurysoftware.com/pixil/pixiloe.php - PIXIL OE v1.0
Major enhancements for this release include: - Dynamic portrait mode - Nano-X now supports display in all four portrait orientations without requiring a server restart. The startup options -N, -L, -R and -D force the server into normal, left, right and upside-down display. The -A option specifies automatic re-orientation to the left or right successively with a mouse-down at the left or right edge of the screen. Run ./nxkbd.sh to see this in action. The server sends a new GR_EVENT_TYPE_PORTRAIT_CHANGED event when the server orientation changes, allowing applications to resize to the new display form factor. There are still some issues using portrait mode with offscreen pixmaps; this version requires offscreen pixmaps to be reconstructed when the above event is received.
- StretchBlit driver support - The Win32 StretchBlt and Nano-X GR_BACKGROUND_STRETCH functions now allow images and blits to use a fast stretchblit driver entry point for resizing image data.
- eCOS operating system support - The complete system can be built for the eCos operating system on the Compaq iPAQ, including all Nano-X demos, linked together with the eCos OS and executing as multiple threads.
- Direct client-side framebuffer mapping - This feature was added to implement extremely fast MPEG video decoders using Microwindows. A client Nano-X application desiring direct access to framebuffer video memory uses the GrOpen ClientFramebuffer API call to initially mmap() the actual framebuffer as shared memory in the client process address space. Then, the GrGetWindowFBInfo API call can be used on any window ID to have Microwindows compute the upper-left hardware pixel address, along with an appropriately faked line pitch (bytes per scan line) that makes the client application think the window is in fact the entire addressable framebuffer video memory. The client can then draw directly into the window, while Microwindows continues to draw the window decorations around the window, while continuing to handle the normal window move, map, and other event reporting/management actions.
- 16 ROP drawing modes for all graphics drawing and blitting - All possible source destination copy, xor, and and or logical functions are now possible for drawing and blit operations. See include/mwtypes.h::MWMODE_* functions for details.
- Many additions to Nano-X API required for Mozilla, SMPEG, SDL, rdesktop, and the PIXIL Operating Environment - A large list of new API calls have been added for a variety of enhancements. Following is a quick description of what's new:
- GrNewCursor, GrDestroyCursor, GrSetWindowCursor - server side cursors
- GrNewBitmapFromData - X11 compatible bitmaps from C data structures
- GrQueryTree - search server window list
- GrDelay - msec standard delay
- GrSetBackgroundPixmap supports GR_BACKGROUND_STRETCH
- GrCreateTimer, GrDestroyTimer server-based periodic timers
- GrSetPortraitMode - set server runtime portrait mode
- GrOpenClientFramebuffer, GrCloseClientFramebuffer - direct framebuffer access
- GrGetWindowFBInfo - get framebuffer information about window
- GrLoadImageFromBuffer, GrDrawImageFromBuffer - image routines not requiring file i/o
- GrGetFontList, GrFreeFontList - font query routines
- GrPeekWaitEvent - wait for input, then peek event
- GrSetGCClipOrigin - set user clip region x,y offset
- Large list of bug fixes and small additions - This version of Microwindows has become more stable, with the inclusion of very many contributions over the last 10 months. Many structures have been expanded to include additional information. See include/mwtypes.h and include/nano-X.h for more information.

Doom port, major enhancements for PDAs and WebPAD devices January 21st, 2001
The long-awaited 0.89pre7 is _finally_ released, and is available at:
ftp://microwindows.org/pub/microwindows/microwindows-0.89pre7.tar.gz
There are some major enhancements in this release, as well as many small additions and bug fixes required to run well on PDAs, WebPAD devices, and set-top boxes. Some of the major enhancements include: - Complete scancode-mode keyboard driver rewrite. The Microwindows keyboard interface is now complete, and all applications now have access to separate keydown and keyup events for every key on the keyboard, including function keys, shift/ctrl/alt, as well as additional keys found on things like the iPAQ. In addition, all keystrokes are reported with a unicode value (read from the Linux kernel tables) as well as an up/down scancode. This modification changed some of the earlier contributed keystroke API and it's now far simpler to catch any keystroke without additional decoding. This modification was required for the Doom port to Microwindows, available from the ftp site. See mwtypes.h for the new keynames. The scancode driver is enabled by setting KBDSCAN=Y in the config file. The X driver has been updated as well so that keystrokes are identical when running Microwindows on X or framebuffer.
- Microwindows now exits with the PAUSE/BREAK key, rather than the ESC key. This change makes it harder to accidentally exit.
- Support was added for the G.Mate YOPY PDA.
- Image support is enhanced with PNG, PBM,PGM and PPM image decoders (thanks Alex)
- Top-level window movement is many times faster using screen-to-screen blitting when dragging windows around. (An option in the window manager also allows drawing an XOR frame instead for slower systems: OUTLINE_MOVE).
- A very nifty launcher application with an extremely cool set of screensavers has been added. Background pixmap support for tiling, centering and such makes background wallpaper a snap. A tetris game has been added. (thanks again to Alex for a heck of a lot of work and a great job on all this!)
- Support for 5/5/5 15bpp screens was added. I finally realized why my home system 16bpp never looked good! This change was required for ongoing work with digital video on Microwindows.
- A pass at a macro-driven Xlib to Nano-X conversion header file, XtoNX.h, which greatly helps hacking Xlib programs into running easily.
- A number of new API entry points were added, including selection api Gr[GetSet]SelectionOwner, GrRequestClientData, GrSendClientData. Screen saver support with a new internal timer mechanism with GrSetScreenSaverTimeout. GrSetBackgroundPixmap, GrNewPixmapFromData for X bitmap display conversion. GrSetWindowTitle, GrSetWindowBorderColor, GrSetWindowBorderSize, GrSetWindowBackgroundColor for the xfreecell port.
- Extensive automatically generated html/pdf/sgml documentation, which has been placed in the microwin/doc/nano-X directory.
- FreeType font caching has been added, enabling _much_ faster display of truetype fonts. (there's still some issues with this, and a change in the font api will be required for the full fix.)
Some of the big bug fixes that are included are: - Fix XFree86 4.0 expose event handling when running on newer X11.
- Fixed nasty slow blitting in the X11 screen driver. (more on this to come)
- Added -mstructure-size-boundary=8 for StrongARM compiles
- Fixed dropped events when running client/server. This was a big problem and numerous events were dropped by clients due to a client/server protocol issue that wasn't handled properly by the client library. We've now had to move to a client-side event queue.
- Linker error when building shared libraries fixed
Thanks again to everybody for the extremely numerous contributions and fixes to this release. I plan on adding a major improvement to the image/blit architecture in the next release.

ViewML and FLNX Upgrade November 2nd, 2000
Version 0.89pre5 of Microwindows is now released at:
ftp://microwindows.org/pub/microwindows/microwindows-0.89pre5.tar.gz
This prerelease adds quite a few bug fixes to Nano-X, as well as major enhancements to the window manager and window style bits. Quite a few subtle bugs in update event reporting, offscreen area copying, blitting, and client disconnect server resource cleanup are fixed. XPM image display has been added.
Now, all font, region, gc, window, pixmap and image server resources are completely deallocated on any client disconnect. The interaction between the window manager and Nano-X is bug free, and new update event subtypes have been added for proper window manager-server interaction and notification. Error event reporting has been rewritten, although there are still some problems when the server generates an error, which normally shouldn't happen.
The Nano-X server has been enhanced to allow a virtual screen size and workspace to be reported that is different from the physical size, in order to emulate PDA screens on the desktop framebuffer. The server also produces a .bmp-convertable file when control-P is pressed for ease in generating screenshots.
This release coincides with the flnx-0.14 and viewml-0.18 releases from Century Software in order to create a completely working ViewML embedded web browser on top of Microwindows.
There are still quite a few more contributions and enhancements that I am working on getting into Microwindows, I'll try to get them in the next cut. Soon, we will be attacking the keyboard input issues and font caching/aliasing that will be required for better speed with ViewML. In addition, the image rendering will be sped up considerably.
I want to give a big thanks to the rapidly growing list of contributors to this project. I feel Microwindows is nearing the stability and feature set it needs for a v1.0 release sometime in the next couple of months.
Following is the complete ChangeLog for this release:
Version 0.89pre5 - 2nd Nov 2000 - greg@censoft.com
* add GdCaptureScreen screen capture for later makebmp processing
* temp #define FASTJPEG in engine/devimage.c for 8bpp fast jpeg display
* free server images on client disconnect

Window Manager Enhanced, NEC Harrier Supported October 17th, 2000
The latest Microwindows tarball is available at:
ftp://microwindows.org/pub/microwindows/microwindows-0.89pre3.tar.gz
This prerelease is mostly bug fixes and enhancements to the Nano-X window manager. A new routine, GrNewWindowEx has been added that allows a window style and title to be specified at the same time the window is created, rather than making a separate call to GrSetWMProperties immediately afterwards.
Also, several new window "properties" were added for interpretation by the window manager. These include the following:
GR_WM_PROPS_APPWINDOW - default look and feel
GR_WM_PROPS_APPFRAME - 3d look
GR_WM_PROPS_BORDER - single black border
GR_WM_PROPS_CAPTION - draw a caption
GR_WM_PROPS_CLOSEBOX - draw a closebox
GR_WM_PROPS_NOMOVE - don't allow user window move
GR_WM_PROPS_NOAUTOMOVE - don't reposition window on map
GR_WM_PROPS_NORAISE - don't allow user z-order change
GR_WM_PROPS_NODECORATE - don't decorate/reparent window
GR_WM_PROPS_NOFOCUS - don't allow user focus
GR_WM_PROPS_NOBACKGROUND - don't erase background
on expose events, application will draw it.
The NEC Harrier board is now supported.
A number of other patches and fixes are also included, we're still trying to get to the bottom of the client hang on disconnect bug. This release is also being synchronized with a big ViewML and FLNX release that implements many more features.
I have received quite a few more patches that I will try to get into the pre4 cut soon. Thanks again to all the fine contributors to this growing project!
The complete ChangeLog follows:
Version 0.89pre3 - 17th October 2000 - greg@censoft.com

Handwriting Recognition, Soft Kbd, New Window Mgr October 3rd, 2000
Microwindows v0.89pre2 is released with quite a few new capabilities, including handwriting recognition, graphics keyboard, and a new window manager. It's available via ftp at:
ftp://microwindows.org/pub/microwindows/microwindows-0.89pre2.tar.gz In addition, a complete set of free truetype Serif, Sans Serif and Courier fonts for running browsers on Microwindows are available, along with fixes to loadable chinese fonts. These packages are available at:
ftp://microwindows.org/pub/microwindows/microwindows-fonts-truetype-0.89pre2.tar.gz
ftp://microwindows.org/pub/microwindows/microwindows-fonts-chinese-0.89pre2.tar.gz This release is aimed towards preparing Microwindows for use on quite a few upcoming PDA projects. The 0.89pre1 announcement was skipped, so there's many changes and enhancements since the 0.88patch1 release. Much work has been on enhancing the Nano-X API and applications. Changes include: - Scribble handwriting recognition is ported to Nano-X. This stroke recognizer currently is Palm-compatible. I'm working on a trainer that will allow users to input their own stroke alphabet if desired. Try running scribble.sh.
- A graphical keyboard for entering typewriter-style keystrokes is implemented, with support for the entire ASCII character set. The example demo is nxkbd.sh.
- The NanoWM window manager has been significantly updated, with an updated look-and-feel and much enhanced application support functionality. System color schemes for windows and the desktop/screentop are supported.
- The VTech Helio is fully supported in this release.
- Quite a few additions to the Nano-X API have been added. Font support was extended for loading truetype fonts from an external font directory. Compiled-in color bitmap support was added, with .bmp file conversion. Changes were made to support running Mozilla on Nano-X.
- Many win32 controls were enhanced with scrollbar support, and changes to the win32 api were added to run Kaffe well.

Microwindows CVS available, patch release for ViewML August 21st, 2000
I have prepared a patched distribution to v0.88 that is required to support the ViewML browser on top of Microwindows, which is available at:
ftp://microwindows.org/pub/microwindows/microwindows-0.88patch1.tar.gz In addition, the Microwindows development tree is now available from a public CVS. Following are the instructions for gaining access:
export CVSROOT=:pserver:anoncvs@cvs.microwindows.org:/usr/cvs
cvs login
(use password: guest)
cvs co microwin
In addition to adding support for transparent color image display for ViewML, the following was added: - Added right/left portrait mode mouse coordinate changes, allowing operation on iPAQ with touchscreen support. When compiled with portrait mode, running the Nano-X server with the -N option reverts to non-portrait mode at startup.
- Added window id parameter to GrInjectKeyboardEvent for Century Software's port of Scribble to Microwindows. This allows Scribble to remember the last window with focus and send keystrokes to that window. Century Software will be releasing Scribble as a GPL'd Nano-X application, rather than adding it to the Microwindows distribution directly (MPL license issues).
- Fixed the Nano-X window manager screen flicker when dragging windows. I'm about to make bigger changes to the window manager for better support of applications running on PDAs (such as the iPAQ).
Various small bug fixes.
Following is the complete ChangeLog:
Version 0.88patch1 - 21st August 2000 - greg@censoft.com
* temp hack scribble to window #2, remove srvutil.c id!=1 hack
* fixed nanowm window move flicker
* added window id parm to GrInjectKeyboardEvent
* added otherid to nano-X focus window events
* fixed BOOL decl in scr_bios.c
* add WM_NCHITTEST fix to tpcal calibrator
* fix ADS and iPAQ touch screen drivers for kernel driver select bug
* added right/left portrait mode mouse fixups, -N cmd line startups
* fixed GsError with no clients core dump
* added transparent color to MWIMAGEHDR format, GdDrawImage, GIF decode ViewML browser and iPAQ ports, Version 0.88 final released August 3rd, 2000
I've finally released version 0.88 of Nano-X and Microwindows, available at:
ftp://microwindows.org/pub/microwindows/microwindows-0.88.tar.gz Although I didn't get in everything I wanted to, this version is stable and provides needed support for some important projects that I'm trying to stay synchronized with. My open source browser project, ViewML, now runs client/server with Nano-X using this version of Microwindows. We've also added a touch screen driver for the Compaq iPAQ, and will have the browser running on it shortly, with full touch screen support. We'll release a ViewML v0.15 shortly with almost all of the features present in the X version. We'll be showing all this at the Linux Expo the week after next, and are also working on binaries that can be downloaded without having to build.
Details on the enhancements for this release include:
GIF, JPEG and BMP image rendering with stretching or shrinking to any size. (PNG and PPM coming soon) Image caching in the server if desired, without sending image data from client to server. We decided to support images directly in Microwindows, rather than bringing in the larger imLib image library, used with the X version of ViewML.
A number of bug fixes were received from ScreenMedia, who are working on releasing the FreePad, based on Microwindows.
A number of new/changed config options, including IPAQMOUSE, ADSMOUSE, and HAVE_GIF_SUPPORT were added
There's still quite a few enhancements recieved that I haven't integrated yet, including caret support, a chinese input method, and some color macro bugs. I will be releasing an enhanced FLTK for Nano-X at the same time as the ViewML v0.15 release.
The detailed changelog for this release is:
Version 0.88 - 3rd August 2000 - greg@censoft.com
* added iPAQ mouse support from Century Software, config IPAQMOUSE
* changed config option TSMOUSE to ADSMOUSE
* added HAVE_GIF_SUPPORT to config, added GIF decoder
* changed image decode algorithms, image is kept in core until drawn
* added GrDrawImageFromFile, GrLoadImageFromFile, GrDrawImageToFit,
GrFreeImage, GrGetImageInfo for GIF, BMP and JPEG
* removed GrJPEG/GdJPEG, GrBMP/GdBMP
* modified MWIMAGEHDR structure, added pitch and bytesperpixel
* wrote decoder for 24bpp .bmp files, enhanced convbmp
* added stretch blit, rewrote image routines in Nano-X for ViewML
* corrected nano-X demo makefiles to work with LINK_APP_INTO_SERVER
* Patches recieved from ScreenMedia: Jan Vehusheia
* nanox/srvnet.c Free allocated events to freelist when destroying
a client.
* nanox/srvutil.c Correctly reassign mouse pointer information when
an application crashes while a mouse button is held pressed down.
* Patches recieved from ScreenMedia: Jon K Hellan
* nanox/srvmain.c (GsInitialize): Initialize wp->owner to NULL.
* drivers/kbd_x11.c (X11_Read): Initialize modifiers also when no
key press pending.

GrSetCursor call.
* added Kevin's patch for destroying eventclient structures
* added Jiwon's patch for NULL name strcpy in devfont.c
* added Kyle's makefile patches, PORTRAIT_MODE=R or L in config
Have fun!
Kaffe and OTI Java port, Version 0.88pre11 released July 10th, 2000
The [hopefully] final prerelease to version 0.88 is now available at:
ftp://microwindows.org/pub/microwindows/microwindows-0.88pre11.tar.gz
This version adds a variety of enhancements that enable Microwindows to host some open source and commercial java environments, as well as almost completing our standard set of Win32 custom controls. - Microwindows can now be configured in an extremely small configuration by setting the new NOFONTSORCLIPPING option in the config file. This allows Microwindows to be used to just open and setup the screen driver, but not use any of the mid level drawing routines, which is perfect for bringing over applications that perform all their own drawing, but require only a framebuffer or screen driver interface to the hardware. In addition, support for no fonts is now included if desired.
- Kevin contributed win32 checkbox, radio and static controls for the win32 api, as well as a not-yet-working combobox control. This nearly complete's Microwindows' low level custom controls for the Windows api.
- Simon contributed a horizontally flipped portrait mode driver for systems where the display is upside down. We should now be able to handle almost all landscape/portrait implementations.
- Andrew contributed a FreeBSD port of Microwindows, as well as hacking the W Window Systems' terminal emulator to run on Nano-X. It provides a VT52 terminal emulation so that now any curses based program can be run as a Nano-X client.
- Other bug fixes and gdi enhancements were added to support the ongoing Kaffe JVM port by Roman.
- The GrSetFontAttr api changed slightly to allow runtime underlining without requiring a font switch, this change should be invisible to most user programs.
I plan on making version 0.88 final in the next few days, it appears that most everything is operational, and I think we need a stable non-prerelease here soon.
The complete ChangeLog follows:
Version 0.88pre11 (IBM OTI java&Kaffe ports) - 10th July 2000 - greg@censoft.com
* added set palette patch from Joe for Embedded Planet /dev/lcd driver
* started adding win32 keyboard support (not working yet)
* added Andrew's port to FreeBSD, Wt wterm terminal emulator port
* fixed convbdf font size error
* added Kevin's not working combobox control
* added George's Isicad Prisma screen driver and config
* added Simon's flipped portrait mode driver (we now have two)
* added updated BC5 makefiles from Ming-Lin Kao
* added HZK font patches from kevin
* added checkbox, radio button and static controls by kevin/cms
* changed GrSetFontAttr,GdSetFontAttr api
* added underlining to font rendering with GrSetFontAttr/MWTF_UNDERLINE
* fix WS_POPUP parent clipping, add owner window handling
* fix delete pen/brush/font resources in ReleaseDC, use DeleteObject
* fix memory leak in GetDCEx using CS_OWNDC
* added nofont.c for null font support
* added NOFONTSORCLIPPING config option for screen driver interface only
* separated engine open and draw routines for small driver interface
* IBM OTI Microview port: no ALPHABLEND, VTSWITCH, FBVGA, EPRINTF chg
FLTK-pre6 on Nano-X, Version 0.88pre10 released June 18th, 2000
A number of quick bug fixes have been made to the last release, resulting in another prerelease available at:
Microwindows except the microwin/src/fonts/chinese directory:
ftp://microwindows.org/pub/microwindows/microwindows-0.88pre10.tar.gz
FLTK ported to Nano-X api:
ftp://microwindows.org/pub/microwindows/fltk-nanox-pre6.tar.gz
A lot of work was performed to get the FLTK port to Nano-X running well. It now looks pretty good, though there's still alot to be done. The Nano-X region routines were slightly revamped to best mirror Xlib calls, the GR_RECT structure was changed, and quite a few bug fixes were made.
Tanghao contributed more changes to fltk-nanox, and fixed some expose event problems, added the region code, and added Nano-X to the configure script.
In addition, I fixed up the Microwindows win32 listbox, and started work on non-client area scrollbars, which I've added to bin/mdemo.
Kevin submitted a patch to get HZK chinese character display working with the t1demo program, and Simon contributed a slider game.
Overall, 0.88pre10 and fltk-nanox-pre6 seem to work well.
Please check out the new features, and send any bug fixes to the list. I'll be pretty busy for about the next week.
The ChangeLog for 0.88pre10 follows:
Version 0.88pre10 (fltk-nx port) - 18th June 2000 - greg@censoft.com
* started adding win32 non-client area scrollbars
* added Simon's contributed slider game (slider.sh)
* added Nano-X GrEqualRegion, GrEmptyRegion, GrOffsetRegion
* added GdEqualRegion, GdEmptyRegion
* changed GdRectInRegion to return partial intersection values
* fixed Nano-X clipping regions relative to drawable
* changed GR_RECT struct to match X, not win32
* changed GrRectInRegion, GrGetRegionBox, GrUnionRectWithRegion parms
to match X
* applied Kevin's HZK font sizing fix
* removed floating point, ldiv from ported progress bar, fixed bugs
* fixed listbox multi-element display code, initial state
* fixed PIXELVALTOCOLORVAL macro typo
Chinese fonts, window manager, polygon regions, arcs, pies, fltk
Version 0.88pre9 released
June 15th, 2000
Well, I've finally completed another big prerelease of Microwindows, thanks alot for all the contributions... I can barely keep up, it seems. This distribution is split up into a couple files because the contributed chinese fonts are large. The following files are now available:
Microwindows except the microwin/src/fonts/chinese directory:
ftp://microwindows.org/pub/microwindows/microwindows-0.88pre9.tar.gz
Chinese fonts (12x12, 16x16 ascii, GB2312 and Unicode-16 and others):
ftp://microwindows.org/pub/microwindows/microwindows-fonts-chinese-0.88pre9.tar.gz
FLTK ported to mwin32 API:
ftp://microwindows.org/pub/microwindows/fltk-mwin32-pre5.tar.gz
FLTK ported to nano-x API:
ftp://microwindows.org/pub/microwindows/fltk-nanox-pre5.tar.gz
I want to merge the two FLTK ports into one, but the Nano-X version was just contributed, and I only had time to make sure that it ran well. (And it looks great with our new Nano-X Window Manager!)
There have been a large number of contributions since the 0.88pre8 cut, and I have included almost everything that has been submitted. Following are some of the highlights: - Chinese character display is now incorporated within Microwindows. There are a few variations, and the work is still in progress. We now support disk-based Unicode-16, GB2312 and Big5 Chinese national standard encoding with contributed 12x12 and 16x16 Han Zi Ku chinese and ascii fonts that display well together. This option is enabled with the HAVE_HZK_SUPPORT config option. Thanks to Tanghao and Jauming for this contribution. Separately, a compiled in chinese font with GB2312 encoding support is enabled with the HAVE_GB2312_SUPPORT option. Thanks to Guo for this. There are a number of issues with the implementation, and I will follow this up in a separate email.
- Nano-X now has a working window manager, thanks to Alex Holden. While still a work in progress, it allows movement of windows and paints title bars, close boxes, and resize borders. This is a great piece of work and I am very impressed. It runs as a separate process, just like the Nano-X processes do.
- Complete region support has been added to Nano-X, which we've been needing in order to proceed with the GTK and FLTK-nanox ports. In addition, full-blown (optional) polygon area regions have been added to our region engine. Thanks to Murphy for most of this work.
- Arcs, pies, and outlined arcs have been added to Microwindows and Nano-X. This was a big pain, although a lot of fun. There's still some bugs in there but we've now got all our basic drawing functions done. I wrote a new demo to show them off.
- Kevin contributed ports of MiniGUI's listbox, edit control and progress bar, and I dressed them up and made them look very 3d for the mwin32 api. The listbox doesn't seem to display more than one item, but more controls will soon be added, like combobox and scrollbars.
- The MIPS based Osprey board is now supported, along with some changes to the touch-pad calibration program, contrib/GPL/tpcal.
- Various fixes to get Nano-widgets and C++ objects to compile are included, as well as a palette patch for VNC. A nasty data corruption bug, only when UPDATEREGIONS was set, is fixed.
The complete ChangeLog for 0.88pre9 follows:
Version 0.88pre9 - 15th June 2000 - greg@censoft.com
* added Chinese Han Zi Ku font support from Tanghao and Jauming
12x12 and 16x16 ascii and chinese fonts

Version 0.88pre8 released May 23, 2000
I have finally put together another release of Microwindows at:
ftp://microwindows.org/pub/microwindows/microwindows-0.88pre8.tar.gz This release has been a while in coming and includes the following major enhancements, including those in the unannounced 0.88pre7 release:
o Fixed font issues with FLTK port, things are now starting to look pretty good. I have released an FLTK snapshot that works well with this release at:
ftp://microwindows.org/pub/microwindows/fltk-pre4.tar.gz
o Added George's VNC viewer for Nano-X. This is very, very cool, and it works, although it's not complete. A Microwindows based system can now communicate with Windows, UNIX and Mac systems and can actually operate any program remotely! This means that handhelds and PDA's can now potentially communicate with servers and have users operate anything, using very little RAM. Currently this only operates in 8bpp mode, but I plan on enhancing it considerably.
o Added Morten's two patches for font selection and external keyboard and mouse input. These patches are necessary for the Opera port to Nano-X and other things Morten is working on. The font selection is turned on with a #define FONTMAPPER in device.h and allows for very sophisticated font selection via the new logical font structure filled in by user programs.
o Finally fixed the Nano-X server crashing on certain client exits. Thanks to Kevin Lin for this.
o Fixed win32 top/baseline/bottom positioning, required for FLTK.
o Added support for DJGPP, BC 5.02, and MINIX.
o Completed port to Embedded Planet's PowerPC box. We now have both touch screen and framebuffer display support when used with Monta Vista's CDK.
o Finished cool minesweeper game, complete with bitmaps.
o Many bug fixes of all types.
We have finally got an initial snapshot of the GTK+/GDK port running on Nano-X. There's still quite a bit to do, as it barely runs. There's a snapshot tarball as well as a diff from the gnome.org GTK 1.3 CVS at: ftp://microwindows.org/gtk. I'm not sure I advise playing with this just yet. Thanks to Paolo for this great work.
The ChangeLog for this release since 0.88pre6b is:
Version 0.88pre8 - 23rd May 2000 - greg@censoft.com
* added Murphy's X vs Microwindows speed tester in contrib/speedtst
* fixed convbdf to not emit nonascii characters
* added Victor's DJGPP port

Interim Version 0.88pre6b April 5, 2000
I've added the patches received since 0.88pre6 and have released another interim version, 0.88pre6b:
ftp://microwindows.org/pub/microwindows-0.88pre6b.tar.gz
The patches received consist mostly of bug fixes, except for Erik's very cool implementation of alpha blending for the X11 screen driver. Now everyone can check out alpha blending for Microwindows on their X11 desktop.
However, there seems to be a big problem in the X11 screen driver when running X in 8bpp mode: Microwindows runs out of colors and starts returning BlackPixel from XAllocColor: thus alpha blending doesn't work in 8bpp mode. In addition, the t1demo.sh has the same problem.
If anybody volunteers to fix this problem in the X11 driver, that would be GREAT!
I've also made some small changes for the Kaffe port in progress, and started porting a minesweeper game.
Attached is the ChangeLog:
Version 0.88pre6b - 5th April 2000 - greg@censoft.com
* added PostThreadMessage
* started porting minesweeper game
* fixed -p persistent mode
* added Kao's BC 5.02 fixes, other pre6 fixes from name changes
* added Steven's patch for polling drivers, HAVE_PERROR config option
* added Erik Hill's alpha blending for X11
* fixed jpeg compile bug
* removed include patch from Shane
Opera, Kaffe, GDK/GTK+ and FLTK ports being supported April 2, 2000
The 0.88pre6 release is now available. Quite a few modifications have been made in order to better support the new work with GDK/GTK+ and Kaffe ports that have just started. The prerelease is available at:
ftp://microwindows.org/pub/microwindows/microwindows-0.88pre6.tar.gz This release contains MAJOR changes to the public header files in an attempt to clean up the exported namespace problems with Microwindows. All Nano-X exports now start with GR_*, and all client callable routines start with Gr*. In addition, quite a bit of work was done making sure that only symbols required to be exported are made public. This should help Microwindows be more suitable for the GDK/TGK+ and FLTK ports now in process.
All Microwindows engine typedefs and defines now start with MW*, and have been placed in mwtypes.h rather than in device.h. Most previous Nano-X and Microwindows applications should compile up without change, except that some of the latest font flags have changed from TF_* to GR_TF*, etc. The public header files for Nano-X and Microwindows remain nano-X.h and windows.h respectively. Oh - GrUnloadFont is renamed GrDestroyFont.
I have created a new GR_LOGFONT (MWLOGFONT) structure for describing fonts more precisely with GrCreateFont. There are now mechanisms to specify a font's height, width, orientation, weight, family, pitch, and character set. The current font selection routine only uses the facename and height, however.
There are quite a few other small bug fixes included, as well as more Win32 API implementations for the Kaffe port. A couple more X11 fonts were converted, and 5x7 and 6x13 versions compiled into the base system for better readability with the terminal emulator. The system now automatically runs in portrait mode if yres > xres.
I plan on working on the new blitting architecture and getting better kbd support next.
Following is the ChangeLog:
Version 0.88pre6 - 2nd April 2000 - greg@censoft.com
* major header file cleanup, fixing namespace pollution
API typdef procs data
Nano-X: GR_* Gr*,nx*,(Gs*) nx*
Microwindows: MW* Mw* mw*
Engine: MW* Gd*,Mw* gr_*, fb*

* completed GetPixel, added PIXELVAL to COLORVAL conversion macros
TrueType and Adobe T1 fonts now supported March 19, 2000
After an _extremely_ lengthy weekend, I have now got both TrueType and Adobe Type 1 font support integrated into Microwindows. Release 0.88pre4 is available at:
ftp://microwindows.org/pub/microwindows/microwindows-0.88pre4.tar.gz Big thanks go to Vidar and Martin for contributing the initial work in this area.
Version 0.88pre4 has had the font routines heavily rewritten to allow multiple renderer support for fonts. We now are able to run using compiled-in builtin fonts (converted using supplied bdf or Windows utilities), as well as using the FreeType and T1 libraries for advanced font rendering. All can be supported simultaneously, if desired.
Support for ascii, unicode-16, and unicode-32 is completed, allowing text to be supplied from applications in these formats. UTF8 support is almost supported, but we need a non-LGPL version of a utf8 to unicode-16 converter. Flags bits to the GrText/GdText routines tell Microwindows how to convert all text before rendering it. Renderers can request text in any format.
Font scaling to any pixel size, as well as rotations in degrees, and antialiasing for 8, 16, 24, and 32bpp is also completed.
Two new Nano-X sample programs ftdemo and t1demo are written to show off the new technologies. The source in microwin/src/engine/devfont.c can be modifed to turn on rotations or turn off antialiasing. There is still some work to do in GdArea, which I will start rewriting soon, as the alphablending and transparency blitting are not performed at the driver level yet, so the antialiasing only works well when you know the final destination color. The plan is to implement two new low level blitters that the font renderers can use, one for alphablending and the other for transparent blitting.
Finally, we've added another touch screen driver for the ADS SA1100 ARM evaluation unit, which features a 640x480 3"x5" LCD display. We'll be contributing the kernel driver soon.
Have fun checking this out!

Version 0.88pre3d release, fltk port available March 12, 2000
I have posted another prerelease of Microwindows at:
ftp://microwindows.org/pub/microwindows/microwindows-0.88pre3d.tar.gz This version contains considerable enhancements which are needed to get FLTK (Fast Light Tool Kit, a C++ widget set) ported to Microwindows. Great progress has been made. Almost all the widgets are at least operational, although more work needs to be done. Screenshots of FLTK running on Microwindows are available at:
ftp://microwindows.org/pub/microwindows/ScreenShots/FLTK I have posted a cut of fltk 1.0.7 hacked for Microwindows at:
ftp://microwindows.org/pub/microwindows/fltk-pre3d.tar.gz Thanks to Shane for the screen shots and the fonts work.
Enhancements to Microwindows in this cut include quite a few win32 API new implementations, including complete region handling including complex regions like round rectangle and ellipses, update regions/clipping, valid/invalid area paint handling, polygon and ellipse drawing, and font routines.
In addition I have added the Linux Penguin to the Microwindows demo so that Microwindows can be better shown at various trade shows. (It was recently displayed at the Embedded Systems Conference in Chicago, and will be at several more in the next month)
For fun, I have added experimental palette animation. This works only on 8bpp palettized displays, and the Microwindow screen fades in on startup, as well as between console switches. It's quite cool.
A variety of bug fixes are included in this release, including a nasty one which took many hours to find. The first 16 colors of the palette were being overwritten if Microwindows was compiled with VTSWITCH=Y. Also, portrait mode is working again.
Following is the ChangeLog:
Version 0.88pre3d (fltk port) - 12th March 2000 - greg@censoft.com
* changed FONTINFO struct, added firstchar, lastchar
* added Shane's fonts patches, added CreateFont, GetTextMetrics,
GetCharWidth, SetAlignText
* debugged nasty VTSWITCH palette changed bug

* added PeekMessage, Ellipse
* added Rosimildo's rtemscfg.h patch
* added GetUpdateRgn, GetUpdateRect, GdOffsetRegion
* added Kyle's GdCopyArea fix

* added SetWindowPos for size,move,show,hide,repaint,zorder
Version 0.88pre3 release, fltk port started March 5, 2000
There's a new cut of Microwindows, 0.88pre3 at: ftp://microwindows.censoft.com/pub/microwindows/microwindows-0.88pre3.tar.gz This version primarily adds dynamic region clipping support, which will be required for the fltk widget set port that's been started. In addition, at Alan Cox's request, a define can be unset to run under the smaller memory usage static cliprect design, for extremely small systems. The full-blown clip region support is pretty cool, since now Microwindows performs region Intersect, Xor, Subtract, and Union. This made it quite easy to add user-specificed clipping regions that can be added/subtracted from the z-order computed visible region. I've hacked the 3d demo to display only within a circular region, thus testing CreateRoundRectRegion as well as blitting into circles. Try it out, it's kinda cool. In addition, Allistair Riddoch performed an amazing feat in about 50 lines of code - he added client-based window management to his Nano-X panel program. Now you can exec programs from the Nano-X server, and move them around! In addition, Rosimildo's Uniform Input Device and MicroFramebuffer Architecture common API for RTEMS and other RTOS's is included. And Victor contributed a TURBOC port, for 16 bit systems, using BGI... Vidar added offscreen drawing support for Nano-X in 0.88pre2, this allows Nano-X programs to draw images offscreen and then use the blitter for flicker free drawing. Version 0.88pre1 introduced a heavily rewritten set of screen drivers for speed, as well as a newly designed interface for offscreen draw handling. With the new interface, the screen driver rather than engine code allocates offscreen buffers, which allows the driver to control how offscreen drawing is initialized and performed. It's alot faster and cleaner. Also, 0.88pre1 introduces the "make install" option, which copies Microwindows and Nano-X header files into /usr/bin/microwin, allowing use of #include in programs. The libraries are renamed libmw*.a, and released into /usr/lib. This allows developers easy access to Microwindows headers and libraries. Following is the ChangeLog since the last major release: Version 0.88pre3 - 5th March 2000 - greg@censoft.com
* added contributed DOS TURBOC port by Victor
* modified bin/mdemo to clip 3d drawing into a circle, added penguin

* added HTBORDER hit testing
* fixed FBVGA blitting, wrong scrdev used on memdc Version 0.87 release February 13, 2000
Microwindows version 0.87 is (finally) released. Source code is available at:
ftp://microwindows.censoft.com/pub/microwindows-0.87.tar.gz Version 0.87 is fairly stable and seems to work well. It's been a long time in coming since the 0.86 release at the end of October, 1999. Following are some of the major additions: - The 0.87 release now runs on Linux framebuffer, Linux SVGAlib, X11, Solaris, RTEMS, ELKS, MSDOS 32 bit with DJGPP, and MSDOS 16 bit with MSC and PACIFIC C (free). The X11 screen driver supports emulating a target screen driver in 1, 2, 4, 8, 16, 24, and 32bpp, without having to cross-compile and run the application on the target device.
- The framebuffer screen drivers have been tested well, and now offer support for 1 through 32 bits per pixel, as well as high speed (software) blitting, and alpha blending. 1 though 8 bpp palettized modes, as well as 16, 24 and 32bpp truecolor modes are supported. The framebuffer drivers have been tuned for speed, although more enhancements are planned.
- The new make system is completed, and a config file now controls all options for specifying target architecture and features options. Cross- compilation support for x86, MIPS, ARM Linux, Solaris, ELKS, DJGPP and RTEMS is included. All demos and libraries are built at once, so it's much easier to link Microwindows when developing an application. A C++ object frameworks has been added. Support for displaying JPEG and BMP file types has been added.
Thanks to everyone for the contributions - it was getting overwhelming for a bit there, but almost all contributions have been added to this release.
I will now start work on getting the tree into CVS, as well as merging contributions for Truetype font support, as well as some cleanups with the screen device structure for speed. In addition, as a result of the press we've been getting, a number of folks are interested getting Microwindows running with their hardware and software.
Following is the detailed ChangeLog:
Version 0.87 - 13th February 2000 - greg@censoft.com
* added VTSWITCH in config to include virtual terminal switch code
* added support for 24bpp, wrote 24bpp fb driver
* fixed 8/8/8 color macros: RGB2PIXEL888, COLOR2PIXEL888, PIXEL888RED
* fixed 32bpp fb bug with psd->ncolors, 32bpp alpha blit bugs
* added fb driver support for FB_VISUAL_DIRECTCOLOR cards (ATI)
* sped up 16, 32bpp blitters by using memcpy
* added large font patches from Kyle

* added Martin's make/configure patches
Microwindows competes with Win2000 and MAC OS X?? February 5, 2000
Microwindows offers features that only the latest Windows 2000 and upcoming MAC OS X have - translucent windows. This feature, sometimes called alpha blending, is being touted by the press as one of the coolest features of these new operating systems, and now we have it (well, almost). Check out this screen shot for what's coming: ftp://microwindows.censoft.com/pub/microwindows/ScreenShots/Microwindows-alphablend.gif The application shown in the screen shot requires applications programming for the effect. Soon, you'll just be able to set a window style bit and get it automatically. Keep posted for details. Feature story in LinuxDevices.com February 1, 2000
LinuxDevices.com featured an article on Microwindows, entitled "Linux + Microwindows: challenger to WinCE". The news feature spoke highly of the Microwindows Project and our ability to offer a WinCE-compatible graphics API now for embedded systems developers. The article was picked up additionally by LinuxDev.net and GeekNews.net. The article can be seen at http://www.linuxdevices.com/cgi-bin/article_view.cgi?artid=AT5381373148.
Version 0.87pre6 release January 31, 2000
YAP (yet another prerelease) of Microwindows 0.87 is available at:
ftp://microwindows.censoft.com/pub/microwindows/microwindows-0.87pre6.tar.gz There have been so many contributions that I feel necessary to release this for quality reasons. I want 0.87 to be quite stable, and I think the Makefile system is now approaching it. Following are the main additions: - Martin contributed an updated X11 based configure program, allowing users to configure various options of Microwindows graphically.
- I've added experimental alpha blending support, just to test the concept. This works on 8, 16 and 32bpp displays. More will be coming in the 0.88 release.
- Morten has contributed GrArea enhancements for high speed rendering, including some 16bpp alpha blending support.
- Chris has contributed a C++ objects framework, which can be enabled via the OBJFRAMEWORK config option.
- Many, many makefile changes and some small bugfixes.
I plan to go final within the next few days, after contributors have had a chance to sign off on the release, if desired.
I want to thank the growing list of contributors to Microwindows. It's really getting fun. I've been working on getting some trade press for the project, and this should be coming real soon, so our efforts will be visible to a much larger group of people. Following is the ChangeLog:
Version 0.87pre6 - 31st January 2000 - greg@censoft.com
* added C++ objects framework from Chris
* added support for multiple read/write/except fd's from Chris
* added Martin's X11 configure program and various Makefile fixes
* added compile time warnings patches from Chris
* added Morten's drawarea patch pre5mr1
* added experimental 8, 16 and 32bpp constant alpha blending to bitblit
(#define ALPHABLEND in device.h and run bin/mterm for demo)
* changed distance-cubed find nearest color to use abs() for speed
* fixed max character height/width alloc; max now 128x128 (configurable)
* small bugfix DRAWON/DRAWOFF in mempl4.c
Version 0.87pre5 release January 26, 2000
Thanks to everyone for the large number of contributions to Microwindows this last week. The quantity was large enough that I feel we need yet another preprelease before 0.87 can go final, since I want the releases to be pretty bug free and stable. This latest prerelease is available at:
ftp://microwindows.censoft.com/pub/microwindows/microwindows-0.87pre5.tar.gz There are quite a few bug fixes and enhancements to the Makefile system, which since pre4 uses config files to set all options. This release includes prebuilt config files for framebuffer, x11, and SVGAlib, in addition to RTEMS builds. Notable additions, aside from many Makefile modifications include: - bug fixed XOR drawing code for 1, 2, and 4bpp fb, thanks to Manuel Teira Paz. In addition, I optimized quite a few routines when I discovered that gcc doesn't generate a shift right for int/2 constructs (try it).
- Morten contributed sizeable changes to the GdArea routine, including a 16bpp drawarea driver for fast GdArea drawing.
- Chris contributed changes moving architecture information out from Makefile.rules to Arch.rules, as well as adding the SetWindowLong function for using window extra bytes. In addition, config files can be kept in a user's home/microwin directory so that the distribution can remain read only.
- Kyle contributed changes for arbitrary-width character drawing in Microwindows by submitting a newly hacked perl script that will translate any width character, along with the appropriate driver modifications. Cool! We now support characters up to 128 bits wide.
- Finally, an innocuous problem regarding unsigned short to int promotion fixed the DJGPP port.
Some patches didn't apply well and overlapped. I will be sending individual email to each contributor with more detailed information. I hope to wrap up 0.87 before Friday.
Following is the detailed Changelog:
Version 0.87pre5 - 26th January 2000 - greg@censoft.com
* prepared prebuilt config files for fb, x11, svga
* added Morten's drawarea driver patch (16bpp only)
* fixed XOR drawing for 1, 2, 4bpp, improved speed with x>>2 not x/4
* applied Chris' FBVGA patch
* applied Rosilmildo's RTEMS compiling patch
* applied Morten's SCREEN_PIXTYPE X11 Makefile patch
* added Chris' SetWindowLong and $(HOME)config and Arch.rules patch
* completed fix for DJGPP compiled mou_dos.c driver
* added Kyle's patches for arbitrarily wide text chars Version 0.87pre4 release January 18, 2000
The final prerelease of version 0.87 is now available at:
ftp://microwindows.censoft.com/pub/microwindows/microwindows-0.87pre4.tar.gz
This release contains quite a few small changes, and a big change to the Makefile system. Morten Jolicoeur contributed a config-based Makefile system back in October, and I've finally caught up enough to make it all work with all the changes since then. This new system allows separate config files to be used to control different machine targets, operating systems, and features without modifying the Makefiles. Martin also wrote a X wish based gui config generator, but I haven't been able to test that. Please check out the config system and let me know how well it works. - Martin's contributed JPEG and BMP file reader/display routines, so that disk based images can be displayed.
- Morten's variable sized PIXELVAL mods, so the servers can be compiled using 8, 16 and 32-bit sized PIXELVALs, for best memory utilization, and allowing applications to create and display images in the native hardware format.
- PF_TRUECOLOR0888 (note that 0) was added for 4 byte pixel packing.
- Victor Rogach contributed a DJGPP port of Microwindows based on the GRX graphics package. GRX sets up enhanced video modes under 32-bit protected mode so that Microwindows now runs on 32-bit DOS.
- Rosimildo contributed changes for the RTEMS operating system, allowing the scr_bios vga driver to be used without making _any_ bios calls.
- Kyle Harris contributed fixes to the 16 and 32bpp framebuffer blitter routines, they didn't work for non-zero offsets.
- Added Dan's GrReparentWindow routine, allowing window managers to be written.
Full Changelog:
Version 0.87pre4 - 18th January 2000 - greg@censoft.com
* added Martin's new config-based Makefile system
* added Martin's JPEG and BMP file reading/display routines
* added Morten's variable PIXELVAL size mods
* added contributed DJGPP/GRX port by Victor Rogachev
* fixed 16bpp and 32bpp fb blit routines, by Kyle Harris
* added Rosimildo's RTEMS changes, scr_bios now runs without bios
* added Dan's GrReparentWindow, fixed GetWindowInfo bug
* added PF_TRUECOLOR0888 for 4 byte packing
* updated doc directory with html faq, architecture
Version 0.87pre3 release December 19, 1999
A hopefully final prerelease for version 0.87 has been released, and is available for download at:
ftp://microwindows.censoft.com/pub/microwindows/microwindows-0.87pre3.tar.gz. This prerelease covers most issues discussed on the NanoGUI list the past couple of weeks. Changes include: - Directory reorganization started. . The Microwindows and Nano-X specific source code, as well as the common engine routines are now in their own directories. Include files are placed in a common directory, etc. Although the source file rearrangement is nearly complete, I still haven't added Martin's new Makefile system (that will be coming, next cut). Thus, there still aren't separate bin and lib directories, but the source organization should make learning easier.
- GrArea() modified to allow different types of pixel data to be displayed. Most of this is discussed in previous email lists. It all works and should be enough for Morten to use as a base for his work. This involved quite a bit of work, but is worth it since Nano-X now supports drawing in device dependent and device-independent manners.
- Quite a few bug fixes, including the Nano-X 64k request packet fix, the GrMoveWindow fix for Nano-X allowing windows to be moved and clipped properly, fixing portrait mode in Microwindows offscreen blitting, and the assert() fix that caused Microwindows to exit sometimes.
For the next cut I plan on adding Martin's make system, which allows for much better configurability, as well as all demos and libraries to be made at once. In addition, I'm probably going to take a swipe at creating a window manager base for Nano-X, so that it's windows can look as cool as Microwindows API, if desired. (No, this won't add much code).
Following is the detailed ChangeLog:
Version 0.87pre3 - 19th December 1999 - greg@censoft.com
* started directory reorganization
* changed LINUX meaning in Makefile, added UNIX for SOLARIS
* fix negative blit index bug found under X11 by Piotr
* set rootwp->parent = NULL for nano-X, fixes GrMoveWindow clip bug
* added COLORVAL<->PIXELVAL conversion macros
* modified GrArea to take packed pixel values of 8, 16 and 24 bits
* modified GrArea to take RGB COLORVALs as well as PIXELVALs
* renamed PF_TRUECOLOR24 to PF_TRUECOLOR888
* added tunable MAXREQUESTSZ to limit max request length
* modified Nano-X demo.c to GrArea() > 64k pixelvals for testing
* fix client/server 64k length bug (request can be 24 bits in length)
* fixed portrait mode in CreateCompatibleBitmap
Version 0.87pre2 release December 14, 1999
The second prerelease for version 0.87 has just been released, and is available for download at:
ftp://microwindows.censoft.com/pub/microwindows/microwindows-0.87pre2.tar.gz This release is primarily intended for inspection and testing of the changes before the directory tree reorganization, planned next.
The major enhancements include: - Portrait mode driver for framebuffer systems. This is a big win for handhelds and palmtops, many of which require portrait mode for normal operation. All graphics output, including mouse movement, hotspots, and text output, are rotated and displayed in portrait mode. In addition, your Microwindows applications can be viewed in portrait mode on the desktop. Try moving the mouse without holding your head sideways!
- The RTEMS operating system port source has been integrated with the main tree.
- Fixes to allow Microwindows to be run on big-endian machines are now included.
- Various bug fixes including the Microwindows terminal emulator pty fix for X11, and Nano-X GrMovewindow fixes for child windows. There are still some issues relating to Nano-X clipping during window movement.
RTEMS Port December 3, 1999
There's been alot of interest and development with Microwindows lately. Rosimildo daSilva has ported Microwindows 0.86 to the RTEMS operating system, available at http://members.xoom.com/rosimildo/rtems_gui.htm. RTEMS is a POSIX-threads compliant real time multitasking operating system which runs on Intel, Motorola, Hitachi, Mips, and many other CPUs. Version 0.87pre1 release December 2, 1999
I have prepared an interim release of Microwindows and Nano-X enhancements, which completes many things folks have asked for, version 0.87pre1. This is available for download at ftp://microwindows.censoft.com/pub/microwindows/microwindows-0.87pre1.tar.gz
The major enhancements include: - Support for running under X11. Microwindows and Nano-X can now run as a user-defined (default 640x480) window under X Windows. The graphics output and look and feel are identical to framebuffer, but will run on any X display server.
- Compile-time options allow configuration to emulate any of the Microwindows truecolor or palette modes, in any pixel depth, including grayscale. This allows a Microwindows or Nano-X application to be emulated exactly, regardless of the host's or target's framebuffer characteristics. Thanks to Tony Rogvall for the X11 driver.
- The client/server network code has been completely rewritten for speed!!! I studied the X11 Xlib implementation and came up with a similar implementation. By queuing all client data until an event or reply is required, Nano-X now runs at extremely high speed. For benchmarking, use the world demo, which plots several thousand points. This demo now runs extremely quickly. Unlike the Xlib implementation, Nano-X still runs synchronously per client, meaning that once a client request packet is sent, the server waits until the whole packet has arrived until servicing another client. This keeps the server code immensely simpler, while still running very quickly. I urge interested folks to check out the implementation, in mwin/src/nanox/nxproto.{ch}, and mwin/src/nanox/client.c.
- Routines were added to allow Nano-X to be used as a "passive library", meaning that an application with it's own main loop can now call into Nano-X occasionally (after a select returns a file descriptor that Nano-X is interested in), and it will all work. This was done for Morten. See mwin/src/nanox/client.c, functions GrPrepareSelect(), GrServiceSelect(), GrMainLoop().
- Routines were added to get the system palette, and translate an RGB color to a PIXELVAL palette index. This was for Richard and the Opera browser. See mwin/src/nanox/srvfunc.c, functions GrGetSystemPalette, GrFindColor().
- A null mouse driver was added for systems without a mouse, by setting NOMOUSE=1 in Makefile.
This is released as 0.87pre1 because I still haven't finished the directory tree reorganization, and adding Martin's cool X11 graphics makefile configuration tool. The client/server code rewrite took alot more time than expected. I am also working on getting all source on CVS.
NanoGUI combined with Microwindows November 13, 1999
Alex Holden, the originator of the NanoGUI project, officially handed over his role to Greg Haerr, so that the NanoGUI and Microwindows projects can officially be available as a single distribution. Alex continues to host the Microwindows/NanoGUI mailing list. Although the releases have been maintained for some time by Greg Haerr, the official distribution site is now moved here. A big thanks goes to Alex for thinking up the NanoGUI idea and hosting the initial web site. Opera Web Browser ported to Microwindows November 11, 1999
The Opera Web Browser, a browser known for it's small footprint and operation on different operating systems, including Windows, BeOS, Linux, Solaris, MacOS and OS/2, has announced they have completed initial work porting Opera to Microwindows. This is a crticial milestone for Microwindows, since it shows that larger, graphics intensive applications can run on top of the Microwindows graphics engine. The Opera port uses the Nano-X api and features jpeg and gif image support, as well as transparent image drawing. The codefile size is 670k. The current Microwindows footprint is less than 100k with no compiled-in images. Version 0.86 release October 28, 1999
Thanks to Brad LaRonde for helping me get this web page out. I have posted an update v0.86 to Microwindows/Nano-X at: ftp://microwindows.censoft.com/pub/microwindows/microwindows-0.86.tar.gz This version completes a major effort, that of implementing off-screen drawing, as well as screen-to-screen blitting. The screen driver interface had to change to accommodate this, and I had to rewrite all the screen drivers. In addition, the blitting routines were written for 1, 2, 4, 8, 16 and 32bpp linear framebuffer devices, as well as the 16 color 4 planes vga (this was a royal pain...) The blitting uses a clipping region traversal algorithm so that blitting is always high speed, even when the destination window is partly obscured. This release also auto-detects most Linux framebuffer implementations, and should have a compiled in driver for it. The standard Microwindows demo is now a graphical terminal emulator, mterm. (No, it doesn't run vi yet, and it doesn't repaint it's screen contents, but it will ;-) This demo requires screen-to-screen blitting for scrolling. The 3d graphics demo now uses offscreen blitting to enhance (read no flicker) the display. Check it out. There is also some experimental full-blown region handling code included, which uses X11's y-x banding region algorithms. (This stuff is truly for those with extra time and brains). It is currently not compiled in, but can be included by replacing devclip.c with devclip2.c. In the next release, arbitrary multi-rectangle clipping regions will be available. I also plan on implementing separate clip regions from update regions for windows, with the system computing the update region as a subset of the clip region. Anyway, this sophisticated region handling is required for smart window painting as well as higher end graphics primitives. Eventually, this will also allow separate source and destination clipping for bitblit operations. Only destination clipping is working now. The next release will have a reorganized directory structure, allowing separate development of Nano-X, widgets, core engine, and Microwindows. I plan on moving the whole thing to a CVS soon. BTW, Microwindows now supports three processor families, according to reports emailed me. We've got i386, 8086, MIPS Vr41xx, and ARM families running ;-) Following is a summary of the ChangeLog:
Version 0.86 - 28th October 1999 - greg@censoft.com - merged framebuffer, elks and msdos vga 16 color 4 planes drivers
- wrote vga bitbit routines (a herculean effort)
- optimized bitblit by traversing window clip region
- added experimental multi-rectangle dynamically allocated regions
- wrote scrolling terminal emulator demo for microwindows
- added WM_FDINPUT msg, WndRegisterFdInput call for terminal emulator
- changed SCREENINFO struct, removed black/white, added bpp, planes
- added offscreen (memory DC) drawing to microwindows
- added BitBlt, CreateCompatibleBitmap, CreateCompatibleDC, DeleteDC
- retired BOGL library, must use new interface for blitting
- converted framebuffer, svgalib, elks and msdos screen drivers (we need blit routines for herc and svgalib still)
- major screen driver interface change, old drivers not compatible
