Button changing its own grid options

[a.clarke11]

Hi
Does anyone know if it is possible to allow a Tkinter button, when
pressed, to change its own grid options?
I've tried various command callbacks, but I'm having problems
referencing the buttons own grid info.
The idea is to get a button to move around, in a grid of other buttons,
when pressed. Any ideas or even better, code, would be appreciated.
Thanks in advance
Tony
