Warning
gdk_window_set_background has been deprecated since version 3.4 and should not be used in newly-written code. Use gdk_window_set_background_rgba() instead.
Sets the background color of window. (However, when using GTK+,
set the background of a widget with gtk_widget_modify_bg() - if
you're an application - or gtk_style_set_background() - if you're
implementing a custom widget.)
