wxPython: changeing dinamically widgets disposition

[Gabriele Farina]

Hi guys, I have to implement a wizard that works like the Mozilla 
Firefox preferences screen (I need some buttons on the left and I have 
to change right content based on the button pressed). How can I manage 
this? I have to create N panels that contains my widgets and then 
displaing them based on the button pressed? I tried somethig like that, 
but it seems that the widgets inside panles cannot be used (they seem 
like disabled).
Some one can give me some help or post me a very small pice of code to 
understand how does what I want works?

bye
