What I'd do is catch the key events.
First make sure you have the right import's
from dabo.ui import dKeys as dKeys
Then when you create the grid you need to bind the event
mygrid= dabo.ui.dGrid(self.....)
mygrid.bindEvent(dEvents.KeyChar, self._catchRet)
def _catchRet(self,evt):
if evt.keyCode in [dKeys.key_Return]:
do something?????
check out
~dabo/ui/uiwx/dKeys.py
The above is untested. But in general it works as above for other controls.
I'm not sure about dGrid. Looking at the dGrid.py it binds many of the
events so it may required that you write your own initEvents (over writing
what was done) in a special class. Just create a sub-class of dGrid and
replace/or add your own initEvents. Don't forget to include a super().
