Hi,
I don't want to derive from a container because I do not want to permit
to add more widgets in my on. If I want to add more buttons it must be
added with other container that will heave my widget and the other button.

I supose that I derive from a container the user of my widget could
remove or add child widgets in my widget. Am I right? Is there another
way to do this?

Tanks.
