Also, some nasty applications may try - to force focus change even in cases when ICCCM 4.2.7 doesn't allow it - (e.g. they may try to activate their main window because the user - definitely "needs" to see something happened - misusing - of TQWidget::setActiveWindow() may be such case). - - There are 4 ways how a window may become active: - - the user changes the active window (e.g. focus follows mouse, clicking - on some window's titlebar) - the change of focus will - be done by KWin, so there's nothing to solve in this case - - the change of active window will be requested using the _NET_ACTIVE_WINDOW - message (handled in RootInfo::changeActiveWindow()) - such requests - will be obeyed, because this request is meant mainly for e.g. taskbar - asking the WM to change the active window as a result of some user action. - Normal applications should use this request only rarely in special cases. - See also below the discussion of _NET_ACTIVE_WINDOW_TRANSFER. - - the change of active window will be done by performing XSetInputFocus() - on a window that's not currently active. ICCCM 4.2.7 describes when - the application may perform change of input focus. In order to handle - misbehaving applications, KWin will try to detect focus changes to - windows that don't belong to currently active application, and restore - focus back to the currently active window, instead of activating the window - that got focus (unfortunately there's no way to FocusChangeRedirect similar - to e.g. SubstructureRedirect, so there will be short time when the focus - will be changed). The check itself that's done is - Workspace::allowClientActivation() (see below). - - a new window will be mapped - this is the most complicated case. If - the new window belongs to the currently active application, it may be safely - mapped on top and activated. The same if there's no active window, - or the active window is the desktop. These checks are done by - Workspace::allowClientActivation(). - Following checks need to compare times. One time is the timestamp - of last user action in the currently active window, the other time is - the timestamp of the action that originally caused mapping of the new window - (e.g. when the application was started). If the first time is newer than - the second one, the window will not be activated, as that indicates - futher user actions took place after the action leading to this new - mapped window. This check is done by Workspace::allowClientActivation(). - There are several ways how to get the timestamp of action that caused - the new mapped window (done in Client::readUserTimeMapTimestamp()) : - - the window may have the _NET_WM_USER_TIME property. This way - the application may either explicitly request that the window is not - activated (by using 0 timestamp), or the property contains the time - of last user action in the application. - - KWin itself tries to detect time of last user action in every window, - by watching KeyPress and ButtonPress events on windows. This way some - events may be missed (if they don't propagate to the toplevel window), - but it's good as a fallback for applications that don't provide - _NET_WM_USER_TIME, and missing some events may at most lead - to unwanted focus stealing. - - the timestamp may come from application startup notification. - Application startup notification, if it exists for the new mapped window, - should include time of the user action that caused it. - - if there's no timestamp available, it's checked whether the new window - belongs to some already running application - if yes, the timestamp - will be 0 (i.e. refuse activation) - - if the window is from session restored window, the timestamp will - be 0 too, unless this application was the active one at the time - when the session was saved, in which case the window will be - activated if there wasn't any user interaction since the time - KWin was started. - - as the last resort, the _KDE_NET_USER_CREATION_TIME timestamp - is used. For every toplevel window that is created (see CreateNotify - handling), this property is set to the at that time current time. - Since at this time it's known that the new window doesn't belong - to any existing application (better said, the application doesn't - have any other window mapped), it is either the very first window - of the application, or its the only window of the application - that was hidden before. The latter case is handled by removing - the property from windows before withdrawing them, making - the timestamp empty for next mapping of the window. In the sooner - case, the timestamp will be used. This helps in case when - an application is launched without application startup notification, - it creates its mainwindow, and starts its initialization (that - may possibly take long time). The timestamp used will be older - than any user action done after launching this application. - - if no timestamp is found at all, the window is activated. - The check whether two windows belong to the same application (same - process) is done in Client::belongToSameApplication(). Not 100% reliable, - but hopefully 99,99% reliable. - - As a somewhat special case, window activation is always enabled when - session saving is in progress. When session saving, the session - manager allows only one application to interact with the user. - Not allowing window activation in such case would result in e.g. dialogs - not becoming active, so focus stealing prevention would cause here - more harm than good. - - Windows that attempted to become active but KWin prevented this will - be marked as demanding user attention. They'll get - the _NET_WM_STATE_DEMANDS_ATTENTION state, and the taskbar should mark - them specially (blink, etc.). The state will be reset when the window - eventually really becomes active. - - There are one more ways how a window can become obstrusive, window stealing - focus: By showing above the active window, by either raising itself, - or by moving itself on the active desktop. - - KWin will refuse raising non-active window above the active one, - unless they belong to the same application. Applications shouldn't - raise their windows anyway (unless the app wants to raise one - of its windows above another of its windows). - - KWin activates windows moved to the current desktop (as that seems - logical from the user's point of view, after sending the window - there directly from KWin, or e.g. using pager). This means - applications shouldn't send their windows to another desktop - (SELI TODO - but what if they do?) - - Special cases I can think of: - - konqueror reusing, i.e. kfmclient tells running Konqueror instance - to open new window - - without focus stealing prevention - no problem - - with ASN (application startup notification) - ASN is forwarded, - and because it's newer than the instance's user timestamp, - it takes precedence - - without ASN - user timestamp needs to be reset, otherwise it would - be used, and it's old; moreover this new window mustn't be detected - as window belonging to already running application, or it wouldn't - be activated - see Client::sameAppWindowRoleMatch() for the (rather ugly) - hack - - konqueror preloading, i.e. window is created in advance, and kfmclient - tells this Konqueror instance to show it later - - without focus stealing prevention - no problem - - with ASN - ASN is forwarded, and because it's newer than the instance's - user timestamp, it takes precedence - - without ASN - user timestamp needs to be reset, otherwise it would - be used, and it's old; also, creation timestamp is changed to - the time the instance starts (re-)initializing the window, - this ensures creation timestamp will still work somewhat even in this case - - KUniqueApplication - when the window is already visible, and the new instance - wants it to activate - - without focus stealing prevention - _NET_ACTIVE_WINDOW - no problem - - with ASN - ASN is forwarded, and set on the already visible window, KWin - treats the window as new with that ASN - - without ASN - _NET_ACTIVE_WINDOW as application request is used, - and there's no really usable timestamp, only timestamp - from the time the (new) application instance was started, - so KWin will activate the window *sigh* - - the bad thing here is that there's absolutely no chance to recognize - the case of starting this KUniqueApp from Konsole (and thus wanting - the already visible window to become active) from the case - when something started this KUniqueApp without ASN (in which case - the already visible window shouldn't become active) - - the only solution is using ASN for starting applications, at least silent - (i.e. without feedback) - - when one application wants to activate another application's window (e.g. KMail - activating already running KAddressBook window ?) - - without focus stealing prevention - _NET_ACTIVE_WINDOW - no problem - - with ASN - can't be here, it's the KUniqueApp case then - - without ASN - _NET_ACTIVE_WINDOW as application request should be used, - KWin will activate the new window depending on the timestamp and - whether it belongs to the currently active application - - _NET_ACTIVE_WINDOW usage: - data.l[0]= 1 ->app request - = 2 ->pager request - = 0 - backwards compatibility - data.l[1]= timestamp -*/ - - -//**************************************** -// Workspace -//**************************************** - - -/*! - Informs the workspace about the active client, i.e. the client that - has the focus (or None if no client has the focus).
