Prevention of focus stealing:
|
|
|
|
KWin tries to prevent unwanted changes of focus, that would result
|
|
from mapping a new window. 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
