Re: [ruby-gnome2-devel-en] Is there a Gdk.Window.property_change method ?

[cedlemo <ce...@gm...>]

Why not trying to define the window as a dock like this :

require "gtk3"
win = Gtk::Window.new
button = Gtk::Button.new(:label => "quit")
button.signal_connect "clicked" do
  Gtk.main_quit
end
win.add(button)
win.show_all
win.window.type_hint = :dock
Gtk.main


Since Gtk support Xlib, Xcb and wayland, the api tend to be more generic.
