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. - -*/ - -#include <assert.h> - -#include <kdebug.h> - -#include "utils.h" -#include "client.h" -#include "workspace.h" -#include "tabbox.h" -#include "group.h" -#include "rules.h" - -namespace KWinInternal -{ - -//******************************* -// Workspace -//******************************* - -void Workspace::updateClientLayer( Client* c ) - { - if( c == NULL ) - return; - if( c->layer() == c->belongsToLayer()) - return; - StackingUpdatesBlocker blocker( this ); - c->invalidateLayer(); // tqinvalidate, will be updated when doing restacking - for( ClientList::ConstIterator it = c->transients().begin(); - it != c->transients().end(); - ++it ) - updateClientLayer( *it ); - } - -void Workspace::updateStackingOrder( bool propagate_new_clients ) - { - if( block_stacking_updates > 0 ) - { - blocked_propagating_new_clients = blocked_propagating_new_clients || propagate_new_clients; - return; - } - ClientList new_stacking_order = constrainedStackingOrder(); - bool changed = ( new_stacking_order != stacking_order ); - stacking_order = new_stacking_order; -#if 0 - kdDebug() << "stacking:" << changed << endl; - if( changed || propagate_new_clients ) - { - for( ClientList::ConstIterator it = stacking_order.begin(); - it != stacking_order.end(); - ++it ) - kdDebug() << (void*)(*it) << *it << ":" << (*it)->layer() << endl; - } -#endif - if( changed || propagate_new_clients ) - { - propagateClients( propagate_new_clients ); - if( active_client ) - active_client->updateMouseGrab(); - } - } - -/*! - Propagates the managed clients to the world. - Called ONLY from updateStackingOrder(). - */ -void Workspace::propagateClients( bool propagate_new_clients ) - { - Window *cl; // MW we should not assume WId and Window to be compatible - // when passig pointers around. - - // restack the windows according to the stacking order -#if 0 - Window* new_stack = new Window[ stacking_order.count() + 2 ]; - int pos = 0; -#endif - NET::WindowType t; - Window shadow; - Window *dock_shadow_stack, *window_stack; - int i, numDocks, pos, topmenu_space_pos; - - dock_shadow_stack = new Window[ stacking_order.count() * 2 ]; - window_stack = new Window[ stacking_order.count() * 2 + 2 ]; - i = 0; - pos = 0; - topmenu_space_pos = 1; // not 0, that's supportWindow !!! - - // Stack all windows under the support window.
