Disable background drawing

[nÿffffe9ant olivier <wxuserbrest yahoo fr>]

Hi,
for technical reason i want to block background drawing for widgets, i did that for a window but it doesn't 
work ? can someone help me please. If everything works well when i open a frame upon this one, then on the 
gtk_frame pixel of previous one must stay. Here is the code :

#include <gtk/gtk.h>

gint close_application( GtkWidget *widget,GdkEvent *event,gpointer   data )
{
  gtk_main_quit ();
  return FALSE;
}

int main(int argc,char **argv)
{
  gtk_init(&argc,&argv);
  GtkWidget *window=gtk_window_new(GTK_WINDOW_TOPLEVEL);

  gtk_widget_realize(window);
  gdk_window_set_back_pixmap(window->window, NULL, FALSE);
  gtk_widget_set_app_paintable(window,TRUE);
  g_signal_connect (G_OBJECT (window), "delete_event",G_CALLBACK(close_application),NULL);
  gtk_widget_show (window);
  gtk_main();
  return 0;
}

Thanks in advance
