-
- 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.
