The signal is key_press_event. Which returns a GdkEvent object. The
keyval attribute tells you which key was pressed.
I use Glade and my sample code is based on my own module which uses libglade,
hope this helps:
import gtk, GDK
# My own module based on libglade:
import window
class text_entry ( window.open ):
def __init__ ( self, title = 'Enter text:', text = '' ):
window.open.__init__ ( self, 'text_entry' )
self.add_handlers ( { 'on_key_press' : self.key_press,
'closed' : self.closed } )
self.get_widget ( 'text_entry' ).set_title ( title )
self.modified = 0
self.text = text
a = self.get_widget ( 'text' )
a.set_text ( text )
a.grab_focus ()
gtk.mainloop ()
def key_press ( self, widget = None, event = None ):
if event.keyval in [GDK.Return, GDK.KP_Enter] :
self.text = widget.get_text ()
self.modified = 1
self.close ()
gtk.mainquit ()
def closed ( self, widget = None ):
gtk.mainquit ()
