a question about widgets...

[Adriano Bonat <adrianobonat yahoo com br>]

Hi list!

This is my first message, then go there:
Why this code bellow don't function?

I want to substitute one widget for another one in the
same place, then I tryed to equal the old widget to
the new (this code is in the function button_click
inside of switch).

I wait for your reply!
Bye.
