[OS X] How to disable auto-hiding of my QMainWindow if I switch application

[Markus]

Hello All,

Since 4.7 I noticed that whenever I have a floating QDockWidget in my QMainWindow the QMainwindow will be auto-hidden if I switch to another application. But If all QDockWidget are docked this is not the case.

So, how do I disable the auto-hiding of my QMainWindow?

Thanks
Markus
