Re: [Vala] Getting semi-transparent window

[Wolfgang Mauer <wolfgang mauer kabelmail de>]

This makes transparent window...

    // Application window
    [GtkTemplate(ui = "/example_prj/window.glade")]
    public class ApplicationWindow : Gtk.ApplicationWindow
    {
        public ApplicationWindow(Gtk.Application application)
        {
            Object(application: application);
set_visual(Gdk.Screen.get_default().get_rgba_visual());
            app_paintable = true;
        }

        public override bool draw (Cairo.Context cr)
        {
            cr.set_source_rgb (0, 0, 0);
            cr.paint_with_alpha (0.5);
            return base.draw(cr);
        }
    }
