Thanks ChrisW67, that names (show / hide) where just to ilustrate the 2 slots, but they have different names in the real application (sorry for my error, I did not take so much care with the names in the example). Im just seaking a valid way to do this (2 qwidgets parentless) or some other way to do it. I need an advice on this matter. Thanks a lot to all of the forum. Its realy a big help.

Thanks
Ramiro
