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() */ Xcb::TransientFor Client::fetchTransient() const { return Xcb::TransientFor(window()); } void Client::readTransientProperty(Xcb::TransientFor &transientFor) { xcb_window_t new_transient_for_id = XCB_WINDOW_NONE; if (transientFor.getTransientFor(&new_transient_for_id)) { m_originalTransientForId = new_transient_for_id; new_transient_for_id = verifyTransientFor(new_transient_for_id, true); } else { m_originalTransientForId = XCB_WINDOW_NONE; new_transient_for_id = verifyTransientFor(XCB_WINDOW_NONE, false); } setTransient(new_transient_for_id); } void Client::readTransient() { Xcb::TransientFor transientFor = fetchTransient(); readTransientProperty(transientFor); } void Client::setTransient(xcb_window_t new_transient_for_id) { if (new_transient_for_id != m_transientForId) { removeFromMainClients(); Client *transient_for = nullptr; m_transientForId = new_transient_for_id; if (m_transientForId != XCB_WINDOW_NONE && !groupTransient()) { transient_for = workspace()->findClient(Predicate::WindowMatch, m_transientForId); assert(transient_for != NULL); // verifyTransient() had to check this transient_for->addTransient(this); } // checkGroup() will check 'check_active_modal' setTransientFor(transient_for); checkGroup(NULL, true); // force, because transiency has changed workspace()->updateClientLayer(this); workspace()->resetUpdateToolWindowsTimer(); emit transientChanged(); } } void Client::removeFromMainClients() { if (transientFor()) transientFor()->removeTransient(this); if (groupTransient()) { for (ClientList::ConstIterator it = group()->members().constBegin(); it != group()->members().constEnd(); ++it) (*it)->removeTransient(this); } } // *sigh* this transiency handling is madness :( // This one is called when destroying/releasing a window. // It makes sure this client is removed from all grouping // related lists. void Client::cleanGrouping() { // qDebug() << "CLEANGROUPING:" << this; // for ( ClientList::ConstIterator it = group()->members().begin(); // it != group()->members().end(); // ++it ) // qDebug() << "CL:" << *it; // ClientList mains; // mains = mainClients(); // for ( ClientList::ConstIterator it = mains.begin(); // it != mains.end(); // ++it ) // qDebug() << "MN:" << *it; removeFromMainClients(); // qDebug() << "CLEANGROUPING2:" << this; // for ( ClientList::ConstIterator it = group()->members().begin(); // it != group()->members().end(); // ++it ) // qDebug() << "CL2:" << *it; // mains = mainClients(); // for ( ClientList::ConstIterator it = mains.begin(); // it != mains.end(); // ++it ) // qDebug() << "MN2:" << *it; for (auto it = transients().constBegin(); it != transients().constEnd(); ) { if ((*it)->transientFor() == this) { removeTransient(*it); it = transients().constBegin(); // restart, just in case something more has changed with the list } else ++it; } // qDebug() << "CLEANGROUPING3:" << this; // for ( ClientList::ConstIterator it = group()->members().begin(); // it != group()->members().end(); // ++it ) // qDebug() << "CL3:" << *it; // mains = mainClients(); // for ( ClientList::ConstIterator it = mains.begin(); // it != mains.end(); // ++it ) // qDebug() << "MN3:" << *it; // HACK // removeFromMainClients() did remove 'this' from transient // lists of all group members, but then made windows that // were transient for 'this' group transient, which again // added 'this' to those transient lists :( ClientList group_members = group()->members(); group()->removeMember(this); in_group = NULL; for (ClientList::ConstIterator it = group_members.constBegin(); it != group_members.constEnd(); ++it) (*it)->removeTransient(this); // qDebug() << "CLEANGROUPING4:" << this; // for ( ClientList::ConstIterator it = group_members.begin(); // it != group_members.end(); // ++it ) // qDebug() << "CL4:" << *it; m_transientForId = XCB_WINDOW_NONE; } // Make sure that no group transient is considered transient // for a window that is (directly or indirectly) transient for it // (including another group transients). // Non-group transients not causing loops are checked in verifyTransientFor(). void Client::checkGroupTransients() { for (ClientList::ConstIterator it1 = group()->members().constBegin(); it1 != group()->members().constEnd(); ++it1) { if (!(*it1)->groupTransient()) // check all group transients in the group continue; // TODO optimize to check only the changed ones?

There are 7 layers, from bottom : DesktopLayer, BelowLayer, NormalLayer, DockLayer, AboveLayer, NotificationLayer, ActiveLayer and OnScreenDisplayLayer (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. We extend the layers provided in NETWM by the NotificationLayer and OnScreenDisplayLayer. The NoficationLayer contains notification windows which are kept above all windows except the active fullscreen window. The OnScreenDisplayLayer is used for eg. volume and brightness change feedback and is kept above all windows since it provides immediate response to a user action. 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 #include "utils.h" #include "client.h" #include "focuschain.h" #include "netinfo.h" #include "workspace.h" #include "tabbox.h" #include "group.h" #include "rules.h" #include "screens.h" #include "unmanaged.h" #include "deleted.h" #include "effects.h" #include "composite.h" #include "screenedge.h" #include "shell_client.h" #include "wayland_server.h" #include namespace KWin { //******************************* // Workspace //******************************* void Workspace::updateClientLayer(AbstractClient* c) { if (c) c->updateLayer(); } void Workspace::updateStackingOrder(bool propagate_new_clients) { if (block_stacking_updates > 0) { if (propagate_new_clients) blocked_propagating_new_clients = true; return; } ToplevelList new_stacking_order = constrainedStackingOrder(); bool changed = (force_restacking || new_stacking_order != stacking_order); force_restacking = false; stacking_order = new_stacking_order; if (changed || propagate_new_clients) { propagateClients(propagate_new_clients); emit stackingOrderChanged(); if (m_compositor) { m_compositor->addRepaintFull(); } if (active_client) active_client->updateMouseGrab(); } } /*! * Some fullscreen effects have to raise the screenedge on top of an input window, thus all windows * this function puts them back where they belong for regular use and is some cheap variant of * the regular propagateClients function in that it completely ignores managed clients and everything * else and also does not update the NETWM property. * Called from Effects::destroyInputWindow so far. */ void Workspace::stackScreenEdgesUnderOverrideRedirect() { if (!rootInfo()) { return; } Xcb::restackWindows(QVector() << rootInfo()->supportWindow() << ScreenEdges::self()->windows()); } /*!
