Re: Window backround not showing

["Tadej Borovšak" <tadeboro gmail com>]

Hello.

You need to tell gtk that your window can be painted from within you
application. Just put this line of code:
gtk_widget_set_app_paintable( window, TRUE );
somewhere before gtk_widget_show function call and you should get your
application background painted.
