Another option if you don't need to catch every possible keypress is to
use the bindKey() method. This does the equivalent of a menu shortcut, so it
works from anywhere in the form. As a result, I usually call bindKey() at the
form level.
Let's say you want to, among other things do something when the user
presses Ctrl+Y on a particular page. In your form's afterInit(), add:
self.bindKey("ctrl+y", self.keypressHandler)
Then create the handler. It's generally easier to create a single
handler that determines which key combo was pressed where, and delegate the
action from that.
def keypressHandler(self, evt):
code = evt.keyCode
shift = evt.shiftDown
ctrl = evt.controlDown
obj = evt.EventObject
if code = ord("Y"):
if self.noTabs.SelectedPageNumber = 2:
# the page you want ctrl-y to be active on
self.doSomeBehavior()
