Description Lionel Landwerlin 2013-04-04 13:24:55 UTC 
The following example give me a transparent window on GTK+ 3.6, not on 3.8 :

=====================================

const Gtk = imports.gi.Gtk;                       
                                                  
Gtk.init(null, null);                             
                                                  
let mwindow = new Gtk.Window({ opacity: 0.5 });   
mwindow.resize(500, 500);                         
mwindow.show();                                   
                                                  
Gtk.main();

On the left GTK+ 3.8, on the right GTK+ 3.6.

Fix gtk_window_set_opacity()

We *do* want to call gdk_window_set_opacity() on toplevels, because
this particular case does work.
