Imply SkipTaskbar and SkipPager depending on Window Type
Review Request #118909 - Created June 23, 2014 and updated
Imply SkipTaskbar and SkipPager depending on Window Type Quoting EWMH: "Applications should not set this hint if _NET_WM_WINDOW_TYPE already conveys the exact nature of the window." This means if the window type implies a SkipPager or SkipTaskbar the window will not have it set. To simplify the life of our API users we should add the state and not require our users to check that manually. Every Normal or Dialog window does not imply that it shouldn't be shown. As our KDE Override is not a proper window type we can assume that it's also a Normal window or a Dialog. The change is done in KWindowInfo and requires that the API user adds NET::WMWindowType explicitly to the properties. NETWinInfo is not adjusted to have it reflect the actual state of the atoms. Here we can assume that the users of the more low-level API are aware of the EWMH spec and will implement these checks themselves.
What about (non override) utility windows (eg. assume Qt would not set floating dock override to bring its own titlebar)? While kwin (iirc by default) hides them for inactive windows, that's rather a feature. -> By their nature, they should not be in the taskbar. But should they not appear in pagers?
