Demosthenes KOPTSIS reported a new bug.

Summary
-------

Implement QMdiArea Qt5 component for Gambas3

Type             : Request
Priority         : Medium
Gambas version   : Unknown
Product          : QT5 component


Description
-----------

I suggest to implement a new MDI Qt5 component based on QMdiArea, and set as deprecated the current Tabstrip mdi component.
The QMdiArea has new features such :
 - maximaized, minimized, resize subwindows,
 - scrollbars when subwindow is larger than mdi area
