Hi,
I need to dynamically hide (and show) a widget or a panel at runtime.
Looking at the API documentation, it seams that the correct method is
setVisible.
However any kind of tests I made failed with an exception raised:
"AttributeError: 'Button' object has no attribute 'style'.
Attached you'll find a simple example that I wrote (for Pyjamas 0.8, Python
2.6.4).
There are two buttons and a label; clicking on one button hides itself and
shows the other one, and viceversa.
Please, can you give me any suggestion on how to make it work?
Thanks
Cesare
