HOWTO: Center window on screen.

[Nikolaj Thygesen <mailinglist diamondbox dk>]

Hi list,

   I've seen this question asked several times and even asked it 
myself, so as I finally made it happen, I thought I'd share my success 
with others in need. Simply putting:

   gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);

at any creative point in your code seems to place windows at random 
positions on screen. What works for me is putting:

   gtk_window_set_type_hint(GTK_WINDOW(window), 
GDK_WINDOW_TYPE_HINT_DIALOG);
   gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);

right before the final call to "gtk_widget_show_all(window);".

   br - N :o)
