To capture the keypress you need bind an event:
someControl.bindEvent(dEvents.KeyChar, self._keypress)
The question in my mind is what you need to bind too. I have not done it but
I bet there is some way to bind an event to a cell.
Below is an example of do something with the keys.
def _keypress(self, evt):
from dabo.ui import dKeys as dKeys
if evt.keyCode in
[dKeys.key_F1,dKeys.key_F2,dKeys.key_F3,dKeys.key_F5,dKeys.key_F6,dKeys.key_F8,dKeys.key_F9,dKeys.key_F10,dKeys.key_F11,dKeys.key_F12]:
return
if evt.keyCode in [dKeys.key_F7, dKeys.key_F4, dKeys.key_Return]:
thestr= self.Form.lookup(evt)
return
#print keyChar
keyChar=evt.keyChar
if (keyChar in """,./<>?;':"[]\\{}|`...@#$%%^&*()_=+"""):
evt.stop()
