/**
* A <code>View</code> is jEdit's top-level frame window.<p>
*
* In a BeanShell script, you can obtain the current view instance from the
* <code>view</code> variable.<p>
*
* The largest component it contains is an {@link EditPane} that in turn
* contains a {@link org.gjt.sp.jedit.textarea.JEditTextArea} that displays a
* {@link Buffer}.
* A view can have more than one edit pane in a split window configuration.
* A view also contains a menu bar, an optional toolbar and other window
* decorations, as well as docked windows.<p>
*
* The <b>View</b> class performs two important operations
* dealing with plugins: creating plugin menu items, and managing dockable
* windows.
*
* <ul>
* <li>When a view is being created, its initialization routine
* iterates through the collection of loaded plugins and constructs the
* <b>Plugins</b> menu using the properties as specified in the
* {@link EditPlugin} class.</li>
* <li>The view also creates and initializes a
* {@link org.gjt.sp.jedit.gui.DockableWindowManager}
* object. This object is
* responsible for creating, closing and managing dockable windows.</li>
* </ul>
*
* This class does not have a public constructor.
* Views can be opened and closed using methods in the <code>jEdit</code>
* class.
