KWin may adjust the value - of this property in some cases (window pointing to itself or creating a loop, - keeping NET::Splash windows above other windows from the same app, etc.). - - Client::transient_for_id is the value of the WM_TRANSIENT_FOR property, after - possibly being adjusted by KWin. Client::transient_for points to the Client - this Client is transient for, or is NULL. If Client::transient_for_id is - poiting to the root window, the window is considered to be transient - for the whole window group, as suggested in NETWM 7.3. - - In the case of group transient window, Client::transient_for is NULL, - and Client::groupTransient() returns true. Such window is treated as - if it were transient for every window in its window group that has been - mapped _before_ it (or, to be exact, was added to the same group before it). - Otherwise two group transients can create loops, which can lead very very - nasty things (bug #67914 and all its dupes). - - Client::original_transient_for_id is the value of the property, which - may be different if Client::transient_for_id if e.g. forcing NET::Splash - to be kept on top of its window group, or when the mainwindow is not mapped - yet, in which case the window is temporarily made group transient, - and when the mainwindow is mapped, transiency is re-evaluated. - - This can get a bit complicated with with e.g. two Konqueror windows created - by the same process. They should ideally appear like two independent applications - to the user. This should be accomplished by all windows in the same process - having the same window group (needs to be changed in Qt at the moment), and - using non-group transients poiting to their relevant mainwindow for toolwindows - etc. KWin should handle both group and non-group transient dialogs well. - - In other words: - - non-transient windows : isTransient() == false - - normal transients : transientFor() != NULL - - group transients : groupTransient() == true - - - list of mainwindows : mainClients() (call once and loop over the result) - - list of transients : transients() - - every window in the group : group()->members() -*/ - -void Client::readTransient() - { - TRANSIENCY_CHECK( this );
