Context menu for button

[Tim Burgess]

Hi,

My port of a QT application to WX continues - I've successfully got a
wxGridSizer laying out my 100 buttons - I now have to provide a context
menufor each button (I agree that this is a nonsense, but I'm still trying
to keep as close to the original application as I can). I've coded the
context menu so that it successfully brings up the options that I want, but
I'm confused as to how I can reliably grab the ID of the button that had
focus before the menu appeared so that I can pass it along for further
processing, since the button doesn't support a right-click event and I'm
having to use EVT_CONTEXT_MENU. Querying the context menu event will return
the ID of the chosen menu option, obviously, and so will a call based on
getting the focus - I'm a bit stuck, so can anybody offer any suggestions,
please?

Best wishes.

IIUC, you are trying to use a single event handler (e.g. OnButtonMenu) for
all of 100 buttons?
If this is the case, you could try using:

wxButton* button = dynamic_cast<wxButton*>(event.GetEventObject());

which should return the button that triggered the context menu event
