wxPython Grid XY Coordinates question

[Kiran]

Hello All,
  I am writing an app in wxPython using a grid.  I need to be able to
recognize what cell in the grid the user is hovering over with the
mouse.  How to do this?
  I tried XYToCell(x, y), but that doesnt work properly because it
thinks that mouse position (0, 0) is the first cell in the grid, and
then goes from there, so if i move the grid to a differernt area on the
screen, the XYToCell is messed up in what it returns.

Any ideas on how to get this to work or any other way?

thanks,
Kiran
