For NET::Unknown windows, transient windows are considered to be NET::Dialog
|
|
windows, for compatibility with non-NETWM clients. 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()
