See what it does and then implement it your own way. Licensing between Qt and KDE are incompatible (quote: code may not be copied from Qt into KDE Platform as Qt is LGPL 2.1 only which would prevent it being used under LGPL 3 - from https://techbase.kde.org/Policies/Licensing_Policy)</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">2 main reasons for this (according to the comments):
- Under X11 restoring the position is tricky
- X11 has a window manager which might be considered responsible for that functionality (and I suppose most modern WMs have the feature enabled by default?)</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Both arguments are moot on MS Windows and OS X, and on both platforms users expect to see window positions restored as well as window size. On OS X there is also little choice in the matter: most applications offer the geometry restore without asking (IIRC it is the same on MS Windows).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I would thus like to propose to port the platform-specific code that existed for MS Windows (and for OS X as a MacPorts patch that apparently was never submitted upstreams). I realise that this violates the message conveyed by the function names but I would like to think that this is a case where function is more important.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">You may also notice that the Mac version does not store resolution-specific settings. This happens to work best on OS X, where multi-screen support has been present since the early nineties, and where window geometry is restored regardless of the screen resolution (i.e. connect a different external screen with a different resolution, and windows will reopen as they were on that screen, not with some default geometry).
I required I can update the comments in the header to reflect this subtlety.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Note that for optimal functionality a companion patch to <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">KMainWindow::event</code> is required:</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;"><div class="codehilite" style="background: #f8f8f8"><pre style="line-height: 125%"><span style="color: #A00000">--- a/src/kmainwindow.cpp</span>

</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This ensures that the window geometry save is performed also after a move (to update the position) without requiring a dummy resizing operation.
Do I need to create a separate RR for this change or is it small enough that I can push it if and when this RR is accepted?</p></pre>
