(Updated Jan. 5, 2013, 5:08 p.m.)
Review request for kdelibs, kwin, Plasma, Aaron J. Seigo, Marco Martin, Martin \
Gräßlin, and Fredrik Höglund.
Changes
-------
Modified patch to check the root event but let it unconditionally pass to Qt (to \
preserve other SelectionOwner notifications) This does also stop additional \
notifications on winId(), so my guess is that passing the root event simply causes \
something (Qt?!) to "steal" it from XFixes.
Remaining question is, whether the explicit XFixesSelectSelectionInput call is still \
required (or we do receive them anyway due to eg. Qt's cnp implementation - from the \
simple testcase the answer is "yes")
Summary (updated)
-----------------
Fix KWindowSystem::compositingChanged signal
Description
-------
It works fine here (tested so far KWindowSystem signal, KSelectionWatcher only with \
kwin) with kwin (shift+alt+f12), xcompmgr, compiz & "metacity -c" and e17. Didn't try \
xfce nor mutter.
Technically:
I do not at all understand why KWindowSystem is *not* watching the root window - \
KSelectionOwner for one is sending events to the root and this also seems the case \
for all other WMs (at least everything now starts to cause the signal to be emitted)
The KSelectionWatcher failure seems to be kwin specific (wrote me a cleaner \
testcase), there'll be some X11 event processing on top that eats away the client \
messages. So this one can be scratched from the patch, the KWindowSystem issue \
remains.
This addresses bug 179042.
