/**
* <p>Keeps track of all dockable windows for a single View, and provides
* an API for getting/showing/hiding them. </p>
*
* <p>Each {@link org.gjt.sp.jedit.View} has an instance of this class.</p>
*
* <p><b>dockables.xml:</b></p>
*
* <p>Dockable window definitions are read from <code>dockables.xml</code> files
* contained inside plugin JARs. A dockable definition file has the following
* form: </p>
*
* <pre><?xml version="1.0"?>
*<!DOCTYPE DOCKABLES SYSTEM "dockables.dtd">
*<DOCKABLES>
* <DOCKABLE NAME="<i>dockableName</i>" MOVABLE="TRUE|FALSE">
* // Code to create the dockable
* </DOCKABLE>
*</DOCKABLES></pre>
*
* <p>The MOVABLE attribute specifies the behavior when the docking position of
* the dockable window is changed. If MOVABLE is TRUE, the existing instance of
* the dockable window is moved to the new docking position, and if the dockable
* window implements the DockableWindow interface (see {@link DockableWindow}),
* it is also notified about the change in docking position before it is moved.
* If MOVABLE is FALSE, the BeanShell code is invoked to get the instance of
* the dockable window to put in the new docking position. Typically, the
* BeanShell code returns a new instance of the dockable window, and the state
* of the existing instance is not preserved after the change. It is therefore
* recommended to set MOVABLE to TRUE for all dockables in order to make them
* preserve their state when they are moved. For backward compatibility reasons,
* this attribute is set to FALSE by default.</p>
* <p>More than one <code><DOCKABLE></code> tag may be present. The code that
* creates the dockable can reference any BeanShell built-in variable
* (see {@link org.gjt.sp.jedit.BeanShell}), along with a variable
* <code>position</code> whose value is one of
* {@link #FLOATING}, {@link #TOP}, {@link #LEFT}, {@link #BOTTOM},
* and {@link #RIGHT}. </p>
*
* <p>The following properties must be defined for each dockable window: </p>
*
* <ul>
* <li><code><i>dockableName</i>.title</code> - the string to show on the dockable
* button. </li>
* <li><code><i>dockableName</i>.label</code> - The string to use for generating
* menu items and action names. </li>
* <li><code><i>dockableName</i>.longtitle</code> - (optional) the string to use
* in the dockable's floating window title (when it is floating).
* If not specified, the <code><i>dockableName</i>.title</code> property is used. </li>
* </ul>
*
* A number of actions are automatically created for each dockable window:
*
* <ul>
* <li><code><i>dockableName</i></code> - opens the dockable window.</li>
* <li><code><i>dockableName</i>-toggle</code> - toggles the dockable window's visibility.</li>
* <li><code><i>dockableName</i>-float</code> - opens the dockable window in a new
* floating window.</li>
* </ul>
*
* Note that only the first action needs a <code>label</code> property, the
* rest have automatically-generated labels.
*
* <p> <b>Implementation details:</b></p>
*
* <p> When an instance of this class is initialized by the {@link org.gjt.sp.jedit.View}
* class, it
* iterates through the list of registered dockable windows (from jEdit itself,
* and any loaded plugins) and
* examines options supplied by the user in the <b>Global
* Options</b> dialog box. Any plugins designated for one of the
* four docking positions are displayed.</p>
*
* <p> To create an instance of a dockable window, the <code>DockableWindowManager</code>
* finds and executes the BeanShell code extracted from the appropriate
* <code>dockables.xml</code> file. This code will typically consist of a call
* to the constructor of the dockable window component. The result of the
* BeanShell expression, typically a newly constructed component, is placed
* in a window managed by this class. </p>
