hi michael,
As described in my previous post, I tried dividing the code into 7
different parts. But the problem still persists. The problem is not
exactly the same. Now after gtk_widget_show() of first part, it shows
a blank dialog within 2 seconds, But the other parts (with all the
widgets) are loaded after 5-6 seconds only.
This is not what I want. I want to see the fully loaded tabs as soon
as their gtk_widget_show(create_dialog_somehow()) is called.
I even tried the following lines to refresh the gtk_main() as soon as
gtk_widget_show() is called. This is how my main() function looks:
g_thread_init (NULL);
gdk_threads_init ();
gdk_threads_enter ();
gtk_init (&argc, &argv);
add_pixmap_directory ("/usr/share/pixmaps/ControlCenter/");
dialog1 = create_dialog1 ();
gtk_widget_show (dialog1);
if(gtk_events_pending())
gtk_main_iteration();
gtk_widget_show(create_display());
if(gtk_events_pending())
gtk_main_iteration();
gtk_widget_show(create_rest());
if(gtk_events_pending())
gtk_main_iteration();
gtk_main ();
gdk_threads_leave ();
return 0;
Thanks and Regards,
Siddharth Kapoor
