Review request for KDE Frameworks and Plasma.
Changes
-------
Submitted with commit 42e924e7f61e7b36266e6c3ca07aa414e88f50ca by David Edmundson to branch master.
Repository: plasma-framework
Description
-------
When we show a Qt window it resets all wm_states, including the
SKIP_TASKBAR state that Qt doesn't support see
QXcbWindow::setNetWmStates
In order to set the flag we need to do it after Qt has mapped the
window. (after a showEvent)
Dialog previously did this using ExposeEvent which we know will happen after show.
However:
1) This is a rather random fix
2) It will be called after TaskManager has been notified of a new window
By merging into the same event we can make sure the flag is set before
the task manager processes the new window. This means task manager will always skip plasma popups.
A better fix will obviously be patching Qt to not reset flags it doesn't know about
and then we can set this flag in the ctor. I shall try and do that for Qt 5.7.
BUG: 332024

Testing
-------
Added debug in libtaskmanager, the window flags are always correct for the new window.
Thanks,
