* The Java Look and Feel, otherwise known as Metal.
* <p>
* Each of the {@code ComponentUI}s provided by {@code
* MetalLookAndFeel} derives its behavior from the defaults
* table. Unless otherwise noted each of the {@code ComponentUI}
* implementations in this package document the set of defaults they
* use. Unless otherwise noted the defaults are installed at the time
* {@code installUI} is invoked, and follow the recommendations
* outlined in {@code LookAndFeel} for installing defaults.
* <p>
* {@code MetalLookAndFeel} derives it's color palette and fonts from
* {@code MetalTheme}. The default theme is {@code OceanTheme}. The theme
* can be changed using the {@code setCurrentTheme} method, refer to it
* for details on changing the theme. Prior to 1.5 the default
* theme was {@code DefaultMetalTheme}. The system property
* {@code "swing.metalTheme"} can be set to {@code "steel"} to indicate
* the default should be {@code DefaultMetalTheme}.
* <p>
* <strong>Warning:</strong>
* Serialized objects of this class will not be compatible with
* future Swing releases. The current serialization support is
* appropriate for short term storage or RMI between applications running
* the same version of Swing. As of 1.4, support for long term storage
* of all JavaBeans<sup><font size="-2">TM</font></sup>
* has been added to the <code>java.beans</code> package.
* Please see {@link java.beans.XMLEncoder}.

/** {@collect.stats}
* This interface is used to mark objects created by ComponentUI delegates.
* The <code>ComponentUI.installUI()</code> and
* <code>ComponentUI.uninstallUI()</code> methods can use this interface
* to decide if a properties value has been overridden. For example, the
* JList cellRenderer property is initialized by BasicListUI.installUI(),
* only if it's initial value is null:
* <pre>
* if (list.getCellRenderer() == null) {
* list.setCellRenderer((ListCellRenderer)(UIManager.get("List.cellRenderer")));
* }
* </pre>
* At uninstallUI() time we reset the property to null if its value
* is an instance of UIResource:
* <pre>
* if (list.getCellRenderer() instanceof UIResource) {
* list.setCellRenderer(null);
* }
*</pre>
* This pattern applies to all properties except the java.awt.Component
* properties font, foreground, and background. If one of these
* properties isn't initialized, or is explicitly set to null,
* its container provides the value. For this reason the
* <code>"== null"</code> is unreliable when installUI() is called
* to dynamically change a components look and feel. So at installUI()
* time we check to see if the current value is a UIResource:
*<pre>
* if (!(list.getFont() instanceof UIResource)) {
* list.setFont(UIManager.getFont("List.font"));
* }
* </pre>

/* GES 2/3/99:
The container listener code was added to support HTML
rendering of tab titles.
Ideally, we would be able to listen for property changes
when a tab is added or its text modified. At the moment
there are no such events because the Beans spec doesn't
allow 'indexed' property changes (i.e. tab 2's text changed
from A to B).
In order to get around this, we listen for tabs to be added
or removed by listening for the container events. we then
queue up a runnable (so the component has a chance to complete
the add) which checks the tab title of the new component to see
if it requires HTML rendering.
The Views (one per tab title requiring HTML rendering) are
stored in the htmlViews Vector, which is only allocated after
the first time we run into an HTML tab. Note that this vector
is kept in step with the number of pages, and nulls are added
for those pages whose tab title do not require HTML rendering.
This makes it easy for the paint and layout code to tell
whether to invoke the HTML engine without having to check
the string during time-sensitive operations.
When we have added a way to listen for tab additions and
changes to tab text, this code should be removed and
replaced by something which uses that. */

* <p>
* Basis of a text components look-and-feel. This provides the
* basic editor view and controller services that may be useful
* when creating a look-and-feel for an extension of
* <code>JTextComponent</code>.
* <p>
* Most state is held in the associated <code>JTextComponent</code>
* as bound properties, and the UI installs default values for the
* various properties. This default will install something for
* all of the properties. Typically, a LAF implementation will
* do more however. At a minimum, a LAF would generally install
* key bindings.
* <p>
* This class also provides some concurrency support if the
* <code>Document</code> associated with the JTextComponent is a subclass of
* <code>AbstractDocument</code>. Access to the View (or View hierarchy) is
* serialized between any thread mutating the model and the Swing
* event thread (which is expected to render, do model/view coordinate
* translation, etc). <em>Any access to the root view should first
* acquire a read-lock on the AbstractDocument and release that lock
* in a finally block.</em>
* <p>
* An important method to define is the {@link #getPropertyPrefix} method
* which is used as the basis of the keys used to fetch defaults
* from the UIManager. The string should reflect the type of
* TextUI (eg. TextField, TextArea, etc) without the particular
* LAF part of the name (eg Metal, Motif, etc).
* <p>
* To build a view of the model, one of the following strategies
* can be employed.
* <ol>
* <li>
* One strategy is to simply redefine the
* ViewFactory interface in the UI. By default, this UI itself acts
* as the factory for View implementations. This is useful
* for simple factories. To do this reimplement the
* {@link #create} method.
* <li>
* A common strategy for creating more complex types of documents
* is to have the EditorKit implementation return a factory. Since
* the EditorKit ties all of the pieces necessary to maintain a type
* of document, the factory is typically an important part of that
* and should be produced by the EditorKit implementation.

* logic for mouse released - which means that we're relying on the fact
