hi everyone, i need some help with my little application,i want lauch a application in a specific work area,i write it in C and using the libwnck library for changing the active desktop.This is a code:

Code:

//-----------------------------------//
//--------Include libraries----------//
//-----------------------------------//

#include 
#include 
#include 
#include 
#include 
#include 
#include 

//to compile use this command:
//  gcc -Wall ChangeWorkSpace.c -o ChangeWorkSpace `pkg-config --cflags --libs glib-2.0 libwnck-1.0 gdk`


//-----------------------------------//
//------------Main function----------//
//-----------------------------------//

int main(int argc, char *argv[], char *envp[])
{
 int i, j;
 WnckScreen *screen;
 WnckWorkspace *workspace;
 int num;
 GTimeVal timestamp;
      
 g_print("- ARGOMENTI PASSATI -\n\n");
 for (i = 0; i < argc; i++)
  g_print("%s\n", argv[i]);
        
 g_print("\n\n- VARIABILI DI AMBIENTE -\n\n");       
 for (j = 0; envp[j] !='\0'; j++) {
  g_print("%s\n", envp[j]);
 }
 
 /* Initialise GDK */
 gdk_init(&argc, &argv);
 
 num = 0;
 
 screen = wnck_screen_get_default();

 int Num_Screens = gdk_display_get_n_screens (gdk_display_get_default());
 g_print("numero di screens : %d \n",Num_Screens);
 
 int Num_Workspace = wnck_screen_get_workspace_count(screen);
 g_print("numero di workspace : %d \n",Num_Workspace); 

 //workspace = wnck_screen_get_workspace(screen, num);

 workspace = wnck_screen_get_active_workspace(screen);
 
 if (!workspace)
 {
  g_print("Workspace number %d does not exist\n", num);
 }

 g_get_current_time(&timestamp);
 wnck_workspace_activate(workspace, timestamp.tv_sec);

 system("gedit");
 
 return 0;
}

it not finished but now it can change desktop and launch gedit,it work good with the metacity VM but not work with compiz VM,why?
i execute the appication with metacity it recognize 4 work area.
i execute the appication with compiz it recognize 0 work area.
where mistake?
BYE

there is already a compiz plugin for placing applications to different viewports, it is called 'Place'.

Besides the fact that gourgi is completely right, compiz is using viewports instead of virtual desktops. See wnck_screen_move_viewport.

At some time point, libwnck maintainer intended to abstract viewports and desktops to some general term, but seemingly he didn't have time to do so yet.

i just know "place window" plug-in but it block the window always in one desktop when the application is started and i need something more dynamic.
i'll try to use wnck_screen_move_viewport function,thanks for the advice.
