<title>Window Behavior</title>

<para> In the upper part of this control module you can see several
tabs: <guilabel>Focus</guilabel>, <guilabel>Titlebar Actions</guilabel>,
<guilabel>Window Actions</guilabel>, <guilabel>Movement</guilabel> and
<guilabel>Advanced</guilabel>. In the
<guilabel>Focus</guilabel> panel you can configure how windows gain or
lose focus, &ie; become active or inactive. Using
<guilabel>Titlebar Actions</guilabel> and <guilabel>Window Actions</guilabel>
you can configure how titlebars and windows react to
mouse clicks. <guilabel>Movement</guilabel> allows you to configure how
windows move and place themselves when started. The
<guilabel>Advanced</guilabel> options cover some specialized options
like <quote>window shading</quote>.
</para>

<note>
<para>
Please note that the configuration in this module will not take effect
if you do not use &plasma;'s native window manager, &kwin;. If you do use a
different window manager, please refer to its documentation for how to
customize window behavior.
</para>
</note>

<sect2 id="focus">
<title>Focus</title>

<para>
The <quote>focus</quote> of the workspace refers to the window which the
user is currently working on. The window with focus is often referred to
as the <quote>active window</quote>.
</para>

<para>
Focus does not necessarily mean the window is the one at the
front &mdash; this is referred to as <quote>raised</quote>, and
although this is configured here as well, focus and raising of windows
are configured independently.
</para>

<sect3 id="focus-focuspolicy">
<title>Windows activation policy</title>

<para>
There are six methods &kwin; can use to determine the current focus:
</para>

<variablelist>

<varlistentry>
<term><guilabel>Click to focus</guilabel></term>
<listitem>
<para>
A window becomes active when you click into it.
This behaviour is common on other operating systems and likely what you want.</para>
</listitem>
</varlistentry>

<varlistentry>
<term><guilabel>Click to focus (mouse precedence)</guilabel></term>
<listitem>
<para>
This is mostly the same as <guilabel>Click to focus</guilabel>.
If an active window has to be chosen by the system
(&eg; because the currently active one was closed) 
the window under the mouse is the preferred candidate.
Unusual, but possible variant of <guilabel>Click to focus</guilabel>.
</para>
</listitem>
</varlistentry>

<varlistentry>
<term><guilabel>Focus follows mouse</guilabel></term>
<listitem>
<para>
Moving the mouse pointer actively over a normal window activates it. New
windows such as the mini command line invoked with
<keycombo action="simul">&Alt;<keycap>F2</keycap></keycombo> will receive the focus,
without you having to point the mouse at them explicitly.
&eg; windows randomly appearing under the mouse will not gain the focus.
Focus stealing prevention takes place as usual.
Think as <guilabel>Click to focus</guilabel> just without having to actually click.
</para>
<para>
In other window managers, this is sometimes known as <quote>Sloppy focus
follows mouse</quote>.
</para>
</listitem>
</varlistentry>

<varlistentry>
<term><guilabel>Focus follows mouse (mouse precedence)</guilabel></term>
<listitem>
<para>
This is mostly the same as <guilabel>Focus follows mouse</guilabel>.
If an active window has to be chosen by the system
(&eg; because the currently active one was closed) 
the window under the mouse is the preferred candidate.
Choose this, if you want a hover controlled focus.
</para>
</listitem>
</varlistentry>

<varlistentry>
<term><guilabel>Focus under mouse</guilabel></term>
<listitem>
<para>
The window that happens to be under the mouse pointer becomes active. If
the mouse is not over a window (for instance, it's over the desktop wallpaper) the last
window that was under the mouse has focus. New windows such as the mini
command line invoked with <keycombo action="simul">&Alt;<keycap>F2</keycap></keycombo> will
not receive the focus, you must move the mouse over them to type.
</para>
</listitem>
</varlistentry>

<varlistentry>
<term><guilabel>Focus strictly under mouse</guilabel></term>
<listitem>
<para>
Similar to <guilabel>Focus under mouse</guilabel>, but even more
strict with its interpretation. Only the window under the mouse pointer is
active. If the mouse pointer is not over a window, no window has focus.
New windows such as the mini command line invoked with
<keycombo action="simul">&Alt;<keycap>F2</keycap></keycombo> will not receive the focus,
you must move the mouse over them to type. 
</para>
</listitem>
</varlistentry>

</variablelist>

<note>
<para>
Note that <guilabel>Focus under mouse</guilabel> and
<guilabel>Focus strictly under mouse</guilabel> prevent certain
features, such as <guilabel>Focus stealing prevention</guilabel> and the 
<keycombo action="simul">&Alt;&Tab;</keycombo>
walk-through-windows dialog, from working properly.
</para>
</note>

</sect3>

<sect3 id="focus-focusdelay">
<title>Delay focus by</title>

<para>
This is the delay after which the window the mouse pointer is over will automatically receive focus.
</para>

</sect3>

<sect3 id="focus-focusstealing">
<title>Focus stealing prevention</title>

<para>
This option specifies how much KWin will try to prevent unwanted focus 
stealing caused by unexpected activation of new windows.
</para> 

<variablelist>

<varlistentry>
<term><guilabel>None</guilabel></term>
<listitem><para>Prevention is turned off and new windows always become activated.</para></listitem>
</varlistentry>

<varlistentry>
<term><guilabel>Low</guilabel></term>
<listitem><para>Prevention is enabled; when some window does not have support 
for the underlying mechanism and KWin cannot reliably decide whether to activate 
the window or not, it will be activated. This setting may have both worse and better 
results than the medium level, depending on the applications.</para></listitem>
</varlistentry>

<varlistentry>
<term><guilabel>Medium</guilabel></term>
<listitem><para>Prevention is enabled.</para></listitem>
</varlistentry>

<varlistentry>
<term><guilabel>High</guilabel></term>
<listitem><para>New windows get activated only 
if no window is currently active or if they belong to the currently active 
application. This setting is probably not really usable when not using mouse 
focus policy.</para></listitem>
</varlistentry>

<varlistentry>
<term><guilabel>Extreme</guilabel></term>
<listitem><para>All windows must be explicitly activated by the user.</para></listitem>
</varlistentry>

</variablelist>

<para>
Windows that are prevented from stealing focus are marked as demanding 
attention, which by default means their taskbar entry will be highlighted. 
This can be changed in the Notifications control module.
</para>

</sect3>

<sect3 id="focus-raisingwindow">
<title>Raising windows</title>

<para>
Besides receiving focus, you can also control under which conditions windows get raised, &ie; brought to the front.
</para>

<para>
You should make sure that at least one of the raising options is enabled, otherwise windows will not be raised at all.
</para>

<para>
<guilabel>Click raises active window</guilabel> will bring a window to the front when it is clicked on. This is enabled by default with a click to focus policy.
</para>

<para>
By activating <guilabel>Raise on hover, delayed by</guilabel> you can alternatively bring a window to the front if the mouse pointer is over that window for a specified period of time. You can determine the delay for this option by using the spin box control. This auto-raising option is only available with a hover to focus policy.
</para>

<tip>
<para>
Setting the delay too short will cause a rapid fire changing of
windows, which can be quite distracting. Most people will like a delay
of 100-300 ms. This is responsive, but it will let you slide over the
corners of a window on your way to your destination without bringing
that window to the front. 
</para>
</tip>

</sect3>

<sect3 id="focus-multiscreen">
<title>Multiscreen behavior</title>

<para>
This controls the behavior of window focus with multiple screens. Note that these options appear only when more than one screen is currently connected.
</para>

<variablelist>

<varlistentry>
<term><guilabel>Active screen follows mouse</guilabel></term>
<listitem>
<para>
When this option is enabled, the active screen (where new windows appear, for example) is the screen containing the mouse pointer. When disabled, the active screen is the screen containing the focused window.
</para>
</listitem>
</varlistentry>

<varlistentry>
<term><guilabel>Separate screen focus</guilabel></term>
<listitem>
<para>
When this option is enabled, focus operations are limited only to the active screen. For instance, when you close a window, then the next window to receive focus will be a window on the active screen, even if there is a more recently used window on a different screen.
</para>
</listitem>
</varlistentry>

</variablelist>

</sect3>

</sect2>

<sect2 id="titlebar-actions">
<title>Titlebar Actions</title>

</variablelist>

<tip>
<para>
You can have windows automatically unshade when you simply place the
mouse over their shaded titlebar. Just check the <link  linkend="advanced-unshading"><guilabel>Window
unshading</guilabel></link> check box in the <guilabel>Advanced</guilabel> tab of
this module. This is a great way to reclaim screen space when you are
cutting and pasting between a lot of windows, for example.

<para id="advanced-remember-positions">
Check the <guilabel>Allow apps to remember the positions of
their own windows</guilabel> item to open windows where they previously were rather than by the placement method chosen above. Note that this remembered position includes the screen assignment, so windows may open on a screen other than the active one if this is where they were last located. Note also that this option is only available on X11, not on Wayland, and is only supported by some KDE applications.

<para>
If you would like some windows to appear on specific positions, screens, or Virtual Desktops, you can set up <guilabel>Window Rules</guilabel> to configure special window or application settings. You can find this by right-clicking on the titlebar of a window and choosing <guimenu>More Actions</guimenu>, or in the <guilabel>Window Rules</guilabel> module in the <guilabel>Window Management</guilabel> section of system settings.
