Ah, OK in that case you have to bind the mouse click to the widget after
you create it. The good news pretty much any widget can be bound.

cell1.Bind(wz.EVT_LEFT_UP, clickEventHandler))

You don;t need a custom widget, wxPython lets you bind mouse events
to pretty much any kind of widget.

Sorry, there isn't a cell widget in wxPython. Exactly what kind of
widget are you using?

Show us the loop where you create the grid and we can probably
show you the bind call you need.

However, wxPython does have a wx.grid.Grid widget which sounds like
it would do exactly what you need without much extra work
on your part. Have you looked into that?

OK, windows, panels, squares are all separate widgets. You need to be
precise. Specifically what kind of widget is the container? Which is the
individual cell? This is very important, you cannot be woolly about it.

Again show us code! Code is much more precise than vague descriptions.
Programming is all about the detail.

Yes, thats what I used for the oxo game in my book. Buttons are easy.
And they work with the mouse without any special binding.

But I'd check the Wx grid control too since it looks like it does
virtually everything you describe for free!
