Locking the handles between QDockWidgets in a QMainWindow

[keek]

Hello there,

I'd like to lock the handles of the splitter elements between the dockwidgets.
I already found out how to lock splitters in general (calling setDisabled() on the handle of the splitter seemed the best way so far and works as intended).
Unfortunately I did not find a way to retrieve the list of all the splitter elements used to separate the visible QDockWidgets in a QMainWindow. @qFindChildren<QSplitter*>(m_mainWindow)@ will only list all the splitters used within the QDockWidgets, yet not the ones used to separate the QDockWidgets.

Is there a way to access these splitter elements' handles?

Thank you in advance
