さかいさん

むとうです。

以下のようなことをするとSEGVりました。
今日は疲れてるので(^^;)、ご報告まで。


require 'gtk2'

Gtk.init

button = Gtk::Button.new("click1")
button2 = Gtk::Button.new("click2")
button.signal_connect("button_press_event") do |w, e|
p e
  button2.signal_emit("button_press_event", e)
end

button2.signal_connect("button_press_event") do |w, e|
  p "button2"
end

vbox = Gtk::VBox.new.add(button).add(button2)
window = Gtk::Window.new.add(vbox).show_all

Gtk.main
