<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>Moving</guilabel>,
<guilabel>Advanced</guilabel>, and <guilabel>Translucency</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>Moving</guilabel> allows you to configure how
windows move and place themselves when started.
The <guilabel>Advanced</guilabel> options cover some specialized options
involving moving windows between desktops and <quote>window
shading</quote>.
The <guilabel>Translucency</guilabel> options support
window manager desktop effects through the kompmgr compositing manager.
</para>
<note>
<para>
Please note the configuration options in this module will not take effect
when you do not use &tde;'s native window manager, &twin;. When you use a
different window manager, please refer to the respective documentation for
customizing window behavior.
</para>
</note>
<sect2 id="focus">
<title>Focus</title>
<para>
The <quote>focus</quote> of the desktop 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-focus-policy">
<title>Focus Policy</title>
<para>
There are four methods &tde; 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.
</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.
</para>
<para>
In other window managers, this is sometimes known as <quote>Sloppy focus
follows mouse.</quote>
</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. When
the mouse is not over a window (for instance, it's on the desktop) 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. When 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>
<note><para>Note that <guilabel>Focus Under Mouse</guilabel> and
<guilabel>Focus Strictly Under Mouse</guilabel> prevent certain
features from working properly, such as the
<keycombo action="simul">&Alt;&Tab;</keycombo> windows switching dialog.</para>
</note>
</listitem>
</varlistentry>
</variablelist>
<para>
After deciding the focus policy, there are window raising options.
</para>
<para>
When enabling <guilabel>Auto raise</guilabel>, &tde; can
bring a window to the front when the mouse is over that window for a
specified period. When <guilabel>Delay focus</guilabel> is enabled,
there will be a delay after which the window the mouse pointer is over will become
active (receive focus).
This is very useful with the <guilabel>Focus Follows Mouse</guilabel> option.
You can determine the delay for both options by using the spin box controls.
</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 milliseconds. 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>
<para>
When you do not use <guilabel>Auto raise</guilabel>, ensure the
<guilabel>Click raises active window</guilabel> option is enabled. You
will not be happy with both <guilabel>Auto raise</guilabel> and
<guilabel>Click raises active window</guilabel> disabled, the net effect is that
windows are not raised at all.
</para>
</sect3>
<sect3 id="focus-focus-stealing">
<title>Focus stealing prevention level</title>
<para>This option specifies how much TWin will try to prevent unwanted focus
stealing caused by unexpected activation of new windows.</para>
<note><para>This feature does not work with the <guilabel>Focus Under Mouse</guilabel>
or <guilabel>Focus Strictly Under Mouse</guilabel> focus policies.</para></note>
<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 TWin 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
when no window is currently active or when 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-navigation">
<title><guilabel>Navigation</guilabel></title>
<para>
In the <guilabel>Navigation</guilabel> frame you can configure the way
switching between applications or desktops using <keycombo
action="simul"> &Alt;&Tab;</keycombo> or <keycombo
action="simul"> &Ctrl;&Tab;</keycombo>.
</para>
<para>
<guilabel>Show window list while switching windows</guilabel>. This option determines
the method used when switching applications using <keycombo action="simul">&Alt;
&Tab;</keycombo>. Pressing and holding &Alt; while
repeatedly pressing and releasing the &Tab; key, can take place in
&tde; mode or in &CDE; mode. In &tde; mode you will see
a window box in the middle of the screen showing the currently selected
application while still holding the &Alt; key. In
&CDE; mode there is no window box and the focus immediately goes to each
new application when selected by pressing the &Tab; key.
</para>
<para>
<guilabel>Traverse windows on all desktops</guilabel>. With this option enabled, switching
windows with <keycombo action="simul">
&Alt;&Tab;</keycombo> will show all applications on all
desktops and take you to the appropriate desktop for the application you
select. When disabled, only windows on your current desktop are
selectable with <keycombo action="simul">
&Alt;&Tab;</keycombo> and you must use <keycombo
action="simul">&Ctrl;&Tab;</keycombo> or other methods to switch to other
desktops.
</para>
<para>
<guilabel>Desktop navigation wraps around</guilabel>. With this option, you cycling
through to the <quote>last</quote> desktop, pressing &Tab; again will
select the first desktop.</para>
<para>
<guilabel>Popup desktop name on desktop switch</guilabel>. Many people name their virtual
desktops according to their purpose or some other naming scheme. You might find this method
convenient to select the desired desktop to tell that you have switched to the right one.</para>
</sect3>
</sect2>
<sect2 id="titlebar-actions">
<title>Titlebar Actions</title>
<para>
In this panel you can configure what happens to windows when a mouse button is
clicked on their titlebars.
</para>
<sect3 id="titlebar-actions-sec1">
<title><guilabel>Titlebar double-click</guilabel></title>
<para>
In this drop down box you can select either
<guilabel>Shade</guilabel>, several variations of
<guilabel>Maximize</guilabel> or <guilabel>Lower</guilabel>.
</para>
<para>
Selecting <guilabel>Maximize</guilabel> causes &tde; to maximize the
window whenever you double click on the titlebar. You can further
choose to maximize windows only horizontally or only
vertically.</para>
<para><guilabel>Shade</guilabel>, on the other hand, causes the window to be
reduced to simply the titlebar. Double clicking on the titlebar again,
restores the window to its normal size.
</para>
</sect3>
<sect3 id="titlebar-actions-sec2">
<title><guilabel>Titlebar wheel event</guilabel></title>
<para>This feature functions much the same as <guilabel>Titlebar double-click</guilabel>
except the mouse scroll wheel causes the events.</para>
<tip>
<para>
You can have windows automatically unshade when you simply place the
mouse over their shaded titlebar. Just check the <guilabel>Enable
hover</guilabel> check box in the <guilabel>Advanced</guilabel> tab of
this module. This is a great way to reclaim desktop space when you are
cutting and pasting between a lot of windows, for example.
</para>
</tip>
</sect3>
<sect3 id="titlebar-actions-sec3">
<title><guilabel>Titlebar &amp; Frame</guilabel></title>
