Summary0001401: Problem w/ MDI windows on OSX (AKA transition from QGLWidget to QOpenGLWidget )
DescriptionThere is a couple problems with the MDI windows on Mac OS X, which I think are caused by the same bug. Firstly, the 3d view windows show up in non 3d windows (start, drawing macro editor, etc.). If you click on one of the windows, it switches to its tab. Secondly, if you tile or cascade the windows, the drawing order is not correct. See attached images.
Steps To ReproduceCreate a new document, and switch to a non 3d view (e.g. the start page)
TagsCocoa, macOS, QOpenGLWidget, Qt5, upstream

Oh, I should add that the Qt MDI example works fine.

To me this seems more an OpenGL issue.

Hmm, yeah, that's probable.

Turns out this a know problem with Qt on Mac, but it doesn't seem to be fixable due to a limitation in the Cocoa API. https://bugreports.qt-project.org/browse/QTBUG-8647

According to the upstream Qt bug (https://bugreports.qt.io/browse/QTBUG-8647) this has been solved in Qt5.4
Any OSX testers able to confirm this?

@peter94 Can you confirm this is fixed based on 0001401:0007593 ?

Per @triplus (in http://forum.freecadweb.org/viewtopic.php?f=10&p=152647#p152647)
> I researched this when working on PieMenu and if i remember correctly transition from QGLWidget to QOpenGLWidget will need to be made to resolve this issue properly. It won't resolve itself by just using Qt5 build as we still use QGLWidget.

 When this is resolved, the changes made in bd28c52fca7f7b1335fb5f27d232a42264b31c2d should be amended.

 Werner recently asked if Qt 5 resolved this issue. Further to @peterl94's comment, Qt 5 alone will not but porting to QGLWidget to QOpenGLWidget should. Mateusz shared an early-stage, narrowly-focused, proof-of-concept qopenglwidget branch (i.e. no where near ready for prime time) that I can confirm will resolve this long-standing issue cleanly.

Werner's recent qtopengl branch resolves this issue as well as Mateusz' proof-of-concept branch. We can safely assume that one the QtOpenGLWidget branch is merged into master, the issue will be resolved.
