  <title>Introduction</title>

  <para>
    The Xfce 4 panel is part of the <ulink url="http://www.xfce.org" 
      type="html">Xfce 4 Desktop Environment</ulink> and features program 
    launchers, panel menus, a clock, a desktop switcher and more. Many 
    aspects of the panel can be configured through graphical dialogs. This 
    manual should provide you with all necessary information on how to adjust 
    the panel to your liking.

  <title>Getting Started</title>
  
  <para>You will usually start the panel as part of your Xfce session, using
    the <application>startxfce4</application> script. The command that will be
    run for the panel is &app;.
  </para>

  <para>
    When you start the panel you will see a bar appearing at the bottom
    of your screen, looking like this:
  </para>

	    a new mail monitor, a clock and a desktop pager; also includes
	    an opened panel menu.
	  </phrase>
	</textobject>
      </mediaobject>
    </screenshot>
  </figure>

  <para>
    The figure shows the default panel configuration with one open panel 
    menu. Hovering the mouse over an item will show a tooltip. The Xfce 
    Panel makes extensive use of left and right mouse buttons. Left clicking
    performs the default action of an item, while right-clicking usually
    brings up a context menu. Shift + left click may commonly be used 
    instead of a right-click. Note that this manual assumes the use of a
    right-handed mouse.
  </para>

  <para>There is a move handle on each side of the panel. You can use it to
    drag the panel anywhere on the edges of the screen. Dragging over half
    of the screen will move the panel to the opposite screen edge. Clicking 
    with the right mouse button on one of them shows a popup menu ... 
    Go on, try it ;-)

  <para>The area between the move handles contains panel items. The available 
    items are are described in the 
    "<ulink url="#panel-items">Panel Items</ulink>" section. Most items 
    perform an action when clicked. Right-clicking on an item will popup a 
    menu from which you can open a properties dialog, remove the item or 
    add a new item. Items can also be added from the right-click menu on one 
    of the move handles (see above).

  <title>Panel Items</title>

  <para>
    The Xfce 4 panel has the possibility to load external plugins as well
    as builtin ones. In this section we will only describe panel items that 
    are installed with the panel.
  </para>
  
  <para>
    The properties dialog for a panel item can be opened from the 
    right-click menu on the item. Each type of panel item has its own 
    configuration dialog. Every dialog offers at least these options:
  </para>

  <itemizedlist>
    <listitem>Change the position of the item on the panel.</listitem>
    <listitem>Remove the item. </listitem>
    <listitem>Close the dialog. </listitem>
  </itemizedlist>


  <sect2 id="launcher-item">
    <title>Launcher</title>

    <para>The most common panel item is the launcher item. It allows you to
      start programs from the panel. The properties dialog offers the
      following options:
    </para>

    <variablelist>
      <varlistentry>
	<term>Icon</term>
	<listitem><para>The icons used by the panel will follow the icon theme
	  you choose from the 
	  <ulink url="xfce-mcs-plugins.html#ui-settings">user interface
	  settings dialog</ulink>. Of course you can also choose a custom
	  icon, either by browsing the file system from the button next
	  to the entry or by dragging an image on the preview area from
	  a file manager.</para></listitem>

	  startup notification. This last option means that the window manager 
	  can show an hourglass while the program is loading. But, the 
	  application has to support it as well. Programs build with Gtk 2.2

    <para>The Xfce Clock has a number of options to change the way it looks. 
      There are three clock types available: analog, digital and LED.
      There is an option to show seconds and for the digital and LED clock
      types you can choose whether the clock will be in 24 hour mode, 12
      hour mode, or 12 hour mode with AM/PM indication. The clock shows the
      current date as a tooltip. Clicking on the clock will not perform any
      action.

  <sect2 id="mailcheck-item">
    <title>Mail checker</title>

    <para>The mail checker monitors a mailbox for incoming mail. The
      mailbox can be in mbox or Maildir format.
    </para>
    
    <para>The mailbox icon will follow
      your icon theme. You can choose the location of the mailbox, the
      command to run when you click on the button and the interval between
      checks. The command has the same options as the launcher item command
      (see <ulink url="#launcher-item" type="html">above</ulink>).
      You can also choose a command to run when new mail arrives.
    </para>

    <para>For advanced usage you can also provide a remote POP3 mailbox if 
      you use the following format for the mailbox entry: 
      <option>pop3://user:password@server:port</option>. If you omit the port
      it will default to 110.
    </para>
    
    <para>Note that this feature is still experimental. Before using it, make 
      sure you have a good network connection, because when the mail check 
      fails it can block the panel.
    </para>

  </sect2>

  <sect2 id="switcher-item">
    <title>Desktop Switcher and Graphical Pager</title>

    <para>The panel provides two items that deal with virtual desktops. A 
      CDE-like desktop switcher, that shows buttons with the desktop name 
      and a graphical pager that shows a miniature view of the desktops and
      even allows you to move windows to another workspace by dragging the
      mini-window in the pager. The graphical pager also allows you to
      change workspaces by using the mouse scrollwheel.
    </para>

    <para>For the graphical pager you can set the number of rows to use, or
      columns when the panel is in vertical mode.</para>

  <title>Panel Menus</title>

  <para>Panel launcher items can have a menu associated with it, which can
    be opened by clicking on the small arrow button next to the item. The
    actual position of these popup buttons is configurable from the global
    preferences dialog. You can also open the menu by pressing the launcher
    button and holding it down. After a short delay the menu will open.
  </para>

  <para>Use the 'Add launcher' item at the top of a panel menu to add
    a new item or drag an executable to this item from a file manager.  
    To remove items from a panel menu use the 'Remove' button in the  
    properties dialog. 
  </para>

  <para>A special feature of panel menus is that they can be detached from the
    panel and live in their own window. To detach a menu click on the small
    line at the bottom of the menu (see the <ulink

  </para>

  <para>The properties dialog for a menu item is opened immediately
    when clicking the right mouse button. The dialog itself is very similar 
    to the dialog for launcher type panel items.

    <para>None of the configuration files, except 
      <filename>kioskrc</filename> and <filename>transparency</filename>, are 
      designed to be edited by hand; in fact the changes will be overwritten 
      if you edit them while the panel and the settings manager are running.
    </para>

  <sect2 id="panel-kiosk">
    <title>Kiosk Mode</title>

    <para>The panel now has support for Kiosk Mode, that will prevent users 
      from making changes to their panel configuration. To use it you have to 
      edit or create the file 
      <filename>${sysconfdir}/xdg/xfce4/kiosk/kioskrc</filename>.
    </para>

    <para>The best way to explain the format of this file is by using an 
      example. The xfce4-panel section of your kioskrc might look like this:
    </para>

<programlisting>
[xfce4-panel]
CustomizePanel=%powerusers,foo
</programlisting>

    <para>This allows only users in the group powerusers and the user foo to 
      customize their panels.
    </para>
    
  </sect2>

  <sect2 id="panel-transparency">
    <title>Transparency</title>

    <para>Please, note that transparency only works with an X server that
      supports the Composite extension, like XOrg &gt;= 6.8.0 and the
      composite extension has been enabled in the configuration file and
      the window manager supports it (e.g. 
      <application>xfwm4</application> has to be compiled with 
      <option>--enable-compositor</option>).
    </para>

    <para>By default the panel will be transparent unless the autohide option
      has been set. When the mouse moves over the panel, the transparency will
      be temporarily removed.
    </para>

    <para>You can create the file
      <filename>&lt;basedir&gt;/xfce4/transparency</filename> if
      you want to change the transparency value for the panel (or
      the iconbox). Create the file and add a line with the format
      <emphasis><option>panel=&lt;value&gt;</option></emphasis>, where
      value is a number between 0 and 100. Setting it to 0 effectively turns
      transparency off.
    </para>
    
    <para>For example, a transparency file may look like this:</para>
    
<programlisting>panel=25
iconbox=0</programlisting>
