(Updated Jan. 9, 2013, 11:56 p.m.) Review request for kdelibs, kwin, Aaron J. Seigo, and Martin Gräßlin. Changes ------- No matter whether the wm support hidden, if nothing is set, the window is not minimized. Description ------- When setting "Keep window thumbnails" to "Always (Breaks minimization)", kwin will keep WM_STATE to be NORMAL when a client is minimized while including _NET_WM_STATE_HIDDEN in its _NET_WM_STATE, as confirmed by ICCCM[1] and Extended Window Manager Hints[2]. However, apart from the expected result (breaks minimization: the client will continue to refresh its content) the minimized window is not shown as minimized in icontasks and pager. These two plasma addons (and probably other addons as well) uses KWindowInfo::isMinimized to determine whether the window is minimized. However, this function threat all window that are not Iconic (WM_STATE != ICONIC) as not minimized, in contradiction to the "Extended window manager hints" which says, "Pagers and similar applications should use _NET_WM_STATE_HIDDEN instead of WM_STATE to decide whether to display a window in miniature representations of the windows on a desktop." This patch correct this behavior and therefore correct the behavior of both pager and icontasks in this situation.
