Anyone have any ideas why this will not work  
been working and googling for hours

It works on Gtk::Window

require ‘gtk2’  
w = Gtk::Window.new  
eb = Gtk::EventBox.new  
w.add(eb)  
eb.add\_events(Gdk::Event::ALL\_EVENTS\_MASK)  
#eb.add\_events(Gdk::Event::KEY\_PRESS\_MASK)

eb.signal\_connect(‘key-press-event’) do |widg, event|  
puts ‘pressed’  
end

w.show\_all  
Gtk::main

Thanks In Advance

The point of Gtk::EventBox is to enable capturing events on widgets  
which can’t. If you add the EventBox to Window, it is, more or less, non  
existing.

Try to add a child to your EventBox. For example :  
eb.add(Gtk::Button.new(“test”))

Try with a vbox, add 2 buttons, one in the event box, focus one or the  
other, and check event is only trigered with the one in the event box.
