Subject: Cancel grid cell editor

Hi all,

Is there a way to cancel a grid cell editor once a cell has
been double clicked. Here is the use case:
I want to replace the inline cell editor with a popup dialog
because of the complex way to select the input.

What I do now is to capture the EVT_GRID_EDITOR_SHOWN event
and on the event handler popup my dialog box and handle the
user input. However I was not able to cancel
(disable/inactivate) the normal cell editor when I decide to
use the popup dialog. I tried calling EndEdit on the cell
editor but it caused the program to crash. I think this is
because EDITOR_SHOWN event is called before BeginEdit?

Anybody know any better way for achieving this? This for me
looked like a very indirect way for doing what I need.

Thanks,

Yusdi

If you look at the demo code for the SimpleGrid, you'll see the following:

def OnEditorShown(self, evt):
## if evt.GetRow() == 6 and evt.GetCol() == 3 and \
## wx.MessageBox("Are you sure you wish to edit this cell?",
## "Checking", wx.YES_NO) == wx.NO:
## evt.Veto()
## return
        evt.Skip()

I think you need to use the commented out portion and edit it accordingly
and put the evt.Skip() in an "else" statement. I do something like this
for my ListCtrl and it works there. I'm sure the same concept applies in
this case.
