Review request for kdelibs, kwin, Aaron J. Seigo, Marco Martin, Martin Gräßlin, and \
Luboš Luňák.
Description (updated)
-------
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)
As for SubstructureNotify, well, the message is sent to the root window - but the \
iccm suggests to send by StructureNotify mask \
(http://tronche.com/gui/x/icccm/sec-2.html) bottom of the page. I just gave it a wild \
shot ("hey, what if we tell everyone") and it absolutely reproducibly enables \
notification of selectionwatcher constructed before the eventloop is up (while it \
also very much seems to be not required once the eventloop is actually up) and i \
don't think it should hurt at all (but might hint a problem in rather the \
selectionwatcher, since we cannot expect others to send by that mask)
This addresses bug 179042.
