Wait for panel notification area window, start in .xinitrc dont work

[Jochen Baier <Jochen Baier stud uni-karlsruhe de>]

hi,

I want to wait for the notification area window. the code below is from 
eggtrayion.c

If I start the program within Gnome everything works fine, but if i 
start the program in .xinitrc

...
wait_for_manager &
gnome-session
...


nothing happens (ok the program waits...), even if i remove the system 
tray and add it again..

I dont know why, hope somebody can help ! thanx Jochen

Code:

#include <stdio.h>
#include <gtk/gtk.h>
#include <gdk/gdkx.h>
#include <gdk/gdk.h>

Atom manager_atom;
Atom selection_atom;

static GdkFilterReturn
root_filter_manager_window (GdkXEvent *xevent, GdkEvent *event, gpointer 
user_data)
{

  XEvent *xev = (XEvent *)xevent;

  if (xev->xany.type == ClientMessage && xev->xclient.message_type == 
manager_atom &&
      xev->xclient.data.l[1] == selection_atom) {

        printf ("manager: here i am\n");
        gtk_main_quit ();
   }

  return GDK_FILTER_CONTINUE;
}

int
main (int argc, char *argv[])
{

   gtk_init (&argc, &argv);

  char temp[50];
  Screen *screen = XDefaultScreenOfDisplay(GDK_DISPLAY());

  sprintf(temp, "_NET_SYSTEM_TRAY_S%i", XScreenNumberOfScreen(screen));
  selection_atom = XInternAtom(GDK_DISPLAY(), temp, True);
  manager_atom = XInternAtom (GDK_DISPLAY(), "MANAGER", False);

  gdk_window_add_filter(gdk_window_lookup (GDK_ROOT_WINDOW()),
      root_filter_manager_window, (gpointer) NULL);

  printf ("waiting...\n");
  gtk_main ();

    /* ..code..  */

  gtk_main();

  return 0;
}
