Re: window survives gtk_widget_destroy(GTK_WIDGET(window));

[Stefan Kost <kost imn htwk-leipzig de>]

Hi Gus,

many thanks for the reply. I found a solution. I am bound to finishing the
event-loop earlier. Therefore now I do

gtk_widget_destroy(GTK_WIDGET(window));
if(!gtk_main_level()) {
  while(gtk_events_pending()) gtk_main_iteration_do(FALSE);
}

ciao
  Stefan
