Because of QT: the menu class hides all the specific Qt management of menus.

In a few words: QT has only a QPopupMenu class that you fills with separators 
and entries, that are not widgets!

To have the same simple semantic as VB, a gambas menu object becomes a true QT 
QPopupMenu widget only when it gets children. Otherwise, it is just an item 
inserted in its parent, which can be a QPopupMenu, or the menubar of the 
window.

And the window menu bar is a QMenuBar widget that don't display the pictures 
associated with its entries. So...

Checked has no effect because QMenuBar do not use it.

Because of QT. QPopupMenu and QMenuBar raise a signal when one if its child is 
clicked, except if it is another poupmenu. And QMenuBar raises the signal, 
but the gambas don't catch it. I didn't do that because I don't like entries 
in the window menu bar that are not real menus.
