Forum: Ruby-Gnome 2 Double-click in Gtk::Entry

The following Gtk::Entry never gets Gdk::Event::BUTTON2_PRESS:

class A < Gtk::Entry
  def initialize
    super
    add_events Gdk::Event::BUTTON_PRESS_MASK
    signal_connect 'button_press_event' do |widget, event|
      select_range 0, -1 if event.event_type ==
Gdk::Event::BUTTON2_PRESS and event.button == 1
      false
    end
  end
end

What am I doing wrong?

Hi

I tried

signal_connect 'button_press_event' do |widget, event|
p "ok" if Gdk::Event::Type::BUTTON2_PRESS==event.event_type
false
end

and it works.

Here’s a complete example:

require 'gtk2'

e = Gtk::Entry.new
e.signal_connect 'button_press_event' do |widget, event|
  p event.event_type
  e.select_range 0, -1 if
    event.event_type == Gdk::Event::BUTTON2_PRESS and
      event.button == 1
end
d = Gtk::Dialog.new
d.vbox.add e
d.show_all
Gtk.main

All I seem to get is two instances of #<Gdk::Event::Type
button-press>.  This is on Windows, by the way, but that shouldn’t be
relevant.

Your example works for me as soon as I change "select_range" to
"select_region".  When I double click, I see:

#<Gdk::Event::Type button-press>
#<Gdk::Event::Type button-press>
#<Gdk::Event::Type 2button-press>

I guess there’s a bug in Gdk for Windows in the version I’m running, 
then.

That’s a bummer.
