Sorry, that I cannot provide a good review as I'm not really into the OSX API, thus my review here might look a little bit nitpicky.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">General comment: maybe rename the directory from "osx" to "cocoa"? After all it's more about the windowing system than the operating system.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">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.)</p></pre>

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.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">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.</p></pre>

This RR presents a "backport" of the modified KDE4 KWindowSystem implementation that has been used in the MacPorts kdelibs4 port for the last 2 or 3 (or more) years.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I have made some initial steps to remove deprecated Carbon API calls, but this is clearly a work in progress.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Open questions include
- is there any justification to run an event handler (or Cocoa observer) to keep track of running applications, possibly even listing all their open windows?
- is there any use for the Qt event listener framework (cf. the NETEventFilter in the X11 plugin)? I haven't yet had time to try to figure out what this "could be good for", and am very open to suggestions in this departments.
- one application for such an event filter would be a listener that catches the opening and closing of all windows by the running process, and keeps track of their <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">WId</code>s. A new method could then be added (to <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">KWindowInfo</code>?) to distinguish <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">WId</code>s created by the running application from "foreign" ones (useful also on Wayland and MS Windows).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;"><code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">KWindowSystem::setMainWindow</code> should become a front for payload provided by the plugins. I'll leave that to the regular/official maintainer(s) of this framework.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This code could probably do with <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">lots</em> of comments; I'll try to add them as questions about this or that bit of code arise.</p></pre>
