Since the functions were moved from Workspace to its own class ScreenEdge and the functionality was formerly called ElectricWindows, the functions still had the old names. They are now consistenly renamed without redundand naming. The function calls were updated as well in all classes where ScreenEdge is used.

|
This file contains things relevant to stacking order and layers.
|
|
|
|
Design:
|
|
|
|
Normal unconstrained stacking order, as requested by the user (by clicking
|
|
on windows to raise them, etc.), is in Workspace::unconstrained_stacking_order.
|
|
That list shouldn't be used at all, except for building
|
|
Workspace::stacking_order. The building is done
|
|
in Workspace::constrainedStackingOrder(). Only Workspace::stackingOrder() should
|
|
be used to get the stacking order, because it also checks the stacking order
|
|
is up to date.
|
|
All clients are also stored in Workspace::clients (except for isDesktop() clients,
|
|
as those are very special, and are stored in Workspace::desktops), in the order
|
|
the clients were created.
|
|
|
|
Every window has one layer assigned in which it is. There are 6 layers,
|
|
from bottom : DesktopLayer, BelowLayer, NormalLayer, DockLayer, AboveLayer
|
|
and ActiveLayer (see also NETWM sect.7.10.). The layer a window is in depends
|
|
on the window type, and on other things like whether the window is active.
|
|
|
|
NET::Splash clients belong to the Normal layer. NET::TopMenu clients
|
|
belong to Dock layer. Clients that are both NET::Dock and NET::KeepBelow
|
|
are in the Normal layer in order to keep the 'allow window to cover
|
|
the panel' Kicker setting to work as intended (this may look like a slight
|
|
spec violation, but a) I have no better idea, b) the spec allows adjusting
|
|
the stacking order if the WM thinks it's a good idea . We put all
|
|
NET::KeepAbove above all Docks too, even though the spec suggests putting
|
|
them in the same layer.
|
|
|
|
Most transients are in the same layer as their mainwindow,
|
|
see Workspace::constrainedStackingOrder(), they may also be in higher layers, but
|
|
they should never be below their mainwindow.
|
|
|
|
When some client attribute changes (above/below flag, transiency...),
|
|
Workspace::updateClientLayer() should be called in order to make
|
|
sure it's moved to the appropriate layer ClientList if needed.
|
|
|
|
Currently the things that affect client in which layer a client
|
|
belongs: KeepAbove/Keep Below flags, window type, fullscreen
|
|
state and whether the client is active, mainclient (transiency).
|
|
|
|
Make sure updateStackingOrder() is called in order to make
|
|
Workspace::stackingOrder() up to date and propagated to the world.
|
|
Using Workspace::blockStackingUpdates() (or the StackingUpdatesBlocker
|
|
helper class) it's possible to temporarily disable updates
|
|
and the stacking order will be updated once after it's allowed again.
