Hi everybody,

In fact I found two functions raise() and lower(). To be sure the widget I want to show is not covered by another widget I call the function raise() just after each call of show(), and I call lower() each time I call hide() and this works fine.

I should have tryed to use the widget stack object instead because it's quite the same behaviour but my solution takes only two line and this time I was a bit lazy

I thank you all for the precious and usefull help you provide me.
