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.

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

That’s a bummer.

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\>
