Running gtk_main in a thread

["Didier Pralon" <didier pralon mdeo fr>]

Hello,

 

I am using gtk+-2.0.2 under cygwin and i would like to run the gtk_main loop in a thread.

 

Here is a testcase of my program. If you compile it and run it, you will see that the window is displayed but does not react to the mouse.

 

It seems like the main loop does not process the windows events or is stuck in a mutex ????

 

Thanks for any help.

 

Didier

 

here is the file test_th.c

void *main_thread (void *args)
{

 

  printf("starting main loop\n");

 

  /* enter the GTK main loop */
  gdk_threads_enter ();
  gtk_main ();
  gdk_threads_leave ();

 

  return NULL;
}

 

int main (int argc, char *argv[])
{
pthread_t main_tid;
GtkWidget *window;

 

  /* init threads */
  g_thread_init (NULL);
  gdk_threads_init ();

 

  /* init gtk */
  gtk_init(&argc, &argv);

 

  /* create a window */
  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  gtk_widget_show (window);

 

  pthread_create (&main_tid, NULL, main_thread, NULL);

 

  while (1)
  {
   sleep(1);
  }
  return 0;
}
