i think you use #active? like so:
gtk_radiobutton_object.active?
thus you have to loop through all the buttons in the group.
but don’t quote me on this

This program will print the current radiobutton’s label if you press ‘p’
inside the window:
#v+
#!/usr/bin/env ruby
require ‘gtk’
window = Gtk::Window.new(Gtk::WINDOW_TOPLEVEL)
window.signal_connect(‘destroy’) { Gtk.main_quit }
box = Gtk::VBox.new(false, 0); window.add box.show
group = nil
[“gtk”, “fox”, “tk”].each do |name|
button = Gtk::RadioButton.new(group, name)
group = button.group
box.add button
button.show
end
window.signal_connect(‘key_press_event’) { |widget, key|
if key.string == “p”
group.each { |b|
b.each { |label|
puts label.get_text if b.active?
}
}
end
}
window.show
Gtk.main
#v-
