During the CommandPanel module development i have developed a rather customizable Preferences dialog, for people being able to rather easily set (groups of) commands. This will get reused in other modules, such as the PieMenu. From a beginning, there was a plan i will add customizable support to the navigation cube menu. @nyholku looks like it is not around anymore, but at that time he did add a QMenu, with an object name set, that i can search for and use as a front-end. Today i explored this a bit further and did notice, that a QMenu gets created for each navigation cube:
https://github.com/FreeCAD/FreeCAD/blob ... .cpp#L1391
Therefore instead of finding the menu once, different set of detections needs to be used, during the whole FreeCAD session. It's not all that problematic, but i was wondering if one of the C++ gurus would be prepared to change this behavior in a way, one (global) QMenu would be created and reused by all navigation cubes?
P.S. In addition i took a quick look, as i always wondered, but its rather unclear to me ATM. How many QMenus are there used in FreeCAD for 3D Viewport and Tree view context menu purposes? Is there a single menu, more of them, created once, more times ...

Re: Question about some of the FreeCAD QMenus
An update. For navigation cube purposes, dealing with more menus, it looks like that should be a non issue. Detection can be done in a rather elegant and straightforward way, with a document observer. As for context menus, i took an additional look and i guess now i understand on how they get populated, Workbench.cpp and View or Tree being a recipient for menu items. Not yet 100% sure, where and how the actual QMenus are created, maybe Tree.cpp and ContextMenu.cpp. Will have to take a closer look next time. They are not direct main window children.
Re: Question about some of the FreeCAD QMenus
For now i will likely completely shift the focus to the initial goal, navigation cube menu support. Small teaser:
Will officially announce the module in a couple of days.
