Summary: Currently we have two signals that are emitted when the Toplevel's geometry changes - geometryShapeChanged() and geometryChanged(). The former signal is used primarily to invalidate cached window quads and the latter is sort of emitted when the frame geometry changes. But it's not that easy. We have a bunch of connects that link those signals together... The worst part about all of this is that the window quads cache gets invalidated every time a geometry update occurs, for example when user moves a window around on the screen. This change introduces a new signal and deprecates the existing geometryChanged signal. frameGeometryChanged is similar to geometryChanged except that it is emitted when an _actual_ geometry change has occurred. We do still emit geometryShapeChanged signal. However, in long term, we need to get rid of this signal or come up with something that makes sense and doesn't require us to waste computational resources.

Transiency stuff: ICCCM 4.1.2.6, NETWM 7.3
|
|
|
|
WM_TRANSIENT_FOR is basically means "this is my mainwindow".
|
|
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.).
|
|
|
|
X11Client::transient_for_id is the value of the WM_TRANSIENT_FOR property, after
|
|
possibly being adjusted by KWin. X11Client::transient_for points to the Client
|
|
this Client is transient for, or is NULL. If X11Client::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, X11Client::transient_for is NULL,
|
|
and X11Client::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).
|
|
|
|
X11Client::original_transient_for_id is the value of the property, which
|
|
may be different if X11Client::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()
