hovering on a menuBar unfocus all other widgets #282
Description
I noticed that hovering on the menuBar with the mouse deselect all focused widgets.
This is an issue for me because users could try to enter text in an editBox and the editBox would lose its focus if the mouse touches the menu.
Typical scenario: trying to select an editBox text with the mouse in a big gesture, resulting in the mouse hovering on a menu and losing the editBox focus.
I think this behavior is inconsistent with the rest of MyGUI: hovering on a comboBox doesn't unfocus other widgets until we click on it, for example.
How could I use the same behavior for menuBar, this is to say, only unfocus other widgets when the user clicks on it, like for comboBox?
