--- Comment #1 from RJVB <rjvber...@gmail.com> --- As an additional observation: Running kate5 on OS X using the XCB plugin is possible even without all X11-specific code included. It may not make much sense, but it does add an interesting observation: the application doesn't get a menubar. Regular/simple Qt applications will get a window-based menubar instead of the Mac-style menubar when run with the XCB QPA; if that doesn't happen that often means that Qt::AA_DontUseNativeMenuBar is set explicitly (normally the platform plugin does that). I cannot find a trace of setting AA_DontUseNativeMenuBar in any of the KF5 frameworks (or Kate' s code itself), but when I set that attribute in Kate's kdemain function something else happens. The application gets TWO menubars. And that leads to many more of the above error messages, concerning other items. I think that lends a lot of support to my hypothesis re: adding QWidgetAction to multiple menus. -- You are receiving this mail because: You are watching all bug changes.
