Hi,
I'll just reply to my own post with an example on how to reproduce
the error-dump. This is no pretty program which simply either inserts or
removes the same widget every other time the window close widget is
clicked - just to keep it brief. Who might I contact regarding this issue??
GtkWidget *window;
GtkWidget *file_widget;
gboolean delete_event(GtkWidget *widget, GdkEvent *event, WindowThread
*_this)
{
if(GtkWidget *sub = gtk_bin_get_child(GTK_BIN(window)))
gtk_container_remove(GTK_CONTAINER(window), sub);
else
gtk_container_add(GTK_CONTAINER(window), file_widget);
return TRUE;
}
int main()
{
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
file_widget = gtk_file_chooser_widget_new(GTK_FILE_CHOOSER_ACTION_SAVE);
g_object_ref(file_widget);
g_signal_connect(G_OBJECT(window), "delete_event",
G_CALLBACK(delete_event), 0);
gtk_container_add(GTK_CONTAINER(window), file_widget);
gtk_widget_show_all(window);
gtk_main();
return 0;
}
br - N :o)
