Ok, well I tried that, but the event doesn't even fire. Here's a
code snippet:
EVT_RIGHT_UP(self, self._OnContextMenu )
def _OnContextMenu(self, event):
dbg('OnContextMenu()', indent=1)
self._contextMenu = wxMenu()
self._contextMenu.Append(wxID_UNDO, "Undo", "")
[...]
EVT_UPDATE_UI(self._contextMenu, wxID_UNDO, self.UndoUIUpdate)
self.PopupMenu(self._contextMenu, event.GetPosition())
self._contextMenu.Destroy()
self._contextMenu = None
dbg(indent=0)
def UndoUIUpdate(self, event=None):
dbg('UndoUIUpdate')
if self._prevValue is None or self._prevValue == self._curValue:
dbg('no previous value to undo')
self._contextMenu.Enable(wxID_UNDO, False)
else:
dbg('previous value present to undo')
self._contextMenu.Enable(wxID_UNDO, True)
The menu pops up, but the UndoUIUpdate never gets called.
If I call UndoUIUpdate directly in the 1st function,
its action gets overridden by the base control before the
menu actually pops!

I tried hooking up EVT_MENU on the above Ids, but
these events don't seem to fire...Because they're not wxWindows events at all...
If you want to have such popup menu on all platforms
your best bet would be to simply show your own.
After experimenting, my workaround is simply to use
a different (new) ID, and enable/disable the menu
item on creation, since it's ephemeral anyway.
But I would like to know what's going on, and if
there's a more proper way to work around this...)
