Nitpickyness is no problem here. I have nothing against renaming the subdirectory, but it'd be something I'd want to leave to the end, for convenience on my end. Also, we'd probably want to remain consistent, or work toward consistency. Currently there are no "cocoa" backend/plugin directories; 3 frameworks use "osx" and another uses "mac". There is also the question to what extent "cocoa" still is and will remain the most appropriate term in this context ... and there is the issue of iOS where some frameworks might be deployed and which might or might not require specific adaptations. (And I'm probably hardly more "into" the iOS APIs as you are into the OS X APIs.) > On Feb. 15, 2016, 8:42 a.m., Martin Gräßlin wrote: > > src/platforms/osx/kwindowsystem_macobjc.mm, line 89 > > <https://git.reviewboard.kde.org/r/126291/diff/2/?file=444312#file444312line89> > > > > Why is the define needed?

From what I understand, the idea was to catch window creation and destruction events to maintain some kind of internal database that would allow to implement a number of the windowing features that aren't supported by the underlying layers. I don't think the feature was ever completed, and it also uses deprecated APIs. I left it in because I thought it could fuel more discussion about whether or not such a feature could make sense to complete the feature set. But it could probably play that same role when moved to the aforementioned scrapbook or some other kind of "junk DNA" file. > On Feb. 15, 2016, 8:42 a.m., Martin Gräßlin wrote: > > src/platforms/osx/kwindowsystem_macobjc.mm, line 175 > > <https://git.reviewboard.kde.org/r/126291/diff/2/?file=444312#file444312line175> > > > > Please use categorized logging.
