Re: [ruby-gnome2-devel-en] what is the status of GTK4 support (under Windows)? (newbie question)

[Bandi-T <ba...@su...>]

My apologies. Indeed it was me.

Here is my successful Ruby transcription of the example from the 
www.gtk.org main page - please feel freel to include it in your 
documentation:

> require 'gtk4'
>
> application = Gtk::Application.new("com.example.GtkApplication", 
> Gio::ApplicationFlags::FLAGS_NONE)
>
> application.signal_connect("activate") do |application|
>   window = Gtk::ApplicationWindow.new(application)
>   button = Gtk::Button.new label: "Hello World!"
>   button.signal_connect("clicked"){|x| window.close}
>   window.set_child button
>   window.present
> end
>
> application.run
