Attempt to deiconify (unminimize) this window. On X11 the window manager may choose to ignore the request to deiconify. When using GTK+, use Gtk.Window.Deiconify instead of the Gdk.Window variant. Or better yet, you probably want to use Gtk.Window.Present, which raises the window, focuses it, unminimizes it, and puts it on the current desktop.
