/**
* JIDE Software created many new components that need their own ComponentUI classes and additional UIDefaults in
* UIDefaults table. LookAndFeelFactory can take the UIDefaults from any existing look and feel and add the extra
* UIDefaults JIDE components need.
* <p/>
* Before using any JIDE components, please make you call one of the two LookAndFeelFactory.installJideExtension(...)
* methods. Basically, you set L&F using UIManager first just like before, then call installJideExtension. See code
* below for an example.
* <code><pre>
* UIManager.setLookAndFeel(WindowsLookAndFeel.class.getName()); // you need to catch the exceptions on this call.
* LookAndFeelFactory.installJideExtension();
* </pre></code>
* LookAndFeelFactory.installJideExtension() method will check what kind of L&F you set and what operating system you
* are on and decide which style of JIDE extension it will install. Here is the rule. <ul> <li> OS: Windows Vista or
* Windows 7, L&F: Windows L&F => OFFICE2007_STYLE </li><li> OS: Windows XP with XP theme on, L&F: Windows L&F =>
* OFFICE2003_STYLE <li> OS: any Windows, L&F: Windows L&F => VSNET_STYLE <li> OS: Linux, L&F: any L&F based on Metal
* L&F => VSNET_STYLE <li> OS: Mac OS X, L&F: Aqua L&F => AQUA_STYLE <li> OS: any OS, L&F: Quaqua L&F => AQUA_STYLE <li>
* Otherwise => VSNET_STYLE </ul> There is also another installJideExtension which takes an int style parameter. You can
* pass in {@link #EXTENSION_STYLE_VSNET}, {@link #EXTENSION_STYLE_ECLIPSE}, {@link #EXTENSION_STYLE_ECLIPSE3X}, {@link
* #EXTENSION_STYLE_OFFICE2003}, {@link #EXTENSION_STYLE_OFFICE2007}, or {@link #EXTENSION_STYLE_XERTO}, {@link
* #EXTENSION_STYLE_OFFICE2003_WITHOUT_MENU}, {@link #EXTENSION_STYLE_OFFICE2007_WITHOUT_MENU}, {@link
* #EXTENSION_STYLE_ECLIPSE_WITHOUT_MENU}, {@link #EXTENSION_STYLE_ECLIPSE3X_WITHOUT_MENU}. In the other word, you will
* make the choice of style instead of letting LookAndFeelFactory to decide one for you. Please note, there is no
* constant defined for AQUA_STYLE. The only way to use it is when you are using Aqua L&F or Quaqua L&F and you call
* installJideExtension() method, the one without parameter.
* <p/>
* Another way is to call {@link LookAndFeelFactory#installDefaultLookAndFeelAndExtension()} which will set the default
* L&Fs based on the OS and install JIDE extension.
* <p/>
* LookAndFeelFactory supports a number of known L&Fs. Some are L&Fs in the JDK such as Metal, Windows, Aqua (on Apple
* JDK only), GTK. We also support some 3rd party L&Fs such as Plastic XP or Plastic 3D, Tonic, A03, Synthetica etc.
* <p/>
* If you are using a 3rd party L&F we are not officially supporting, you might need to customize it. Here are two
* classes you can use - {@link LookAndFeelFactory.UIDefaultsInitializer} and {@link
* LookAndFeelFactory.UIDefaultsCustomizer}.
* <p/>
* Let's start with UIDefaultsCustomizer. No matter what unknown L&F you are trying to use, LookAndFeelFactory's
* installJideExtension() will try to install the UIDefaults that JIDE components required. Hopefully JIDE will run on
* your L&F without any exception. But most likely, it won't look very good. That's why you need {@link
* UIDefaultsCustomizer} to customize the UIDefaults.
* <p/>
* Most likely, you will not need to use {@link UIDefaultsInitializer}. The only exception is Synth L&F and any L&Fs
* based on it. The reason is we calculate all colors we will use in JIDE components from existing well-known
* UIDefaults. For example, we will use UIManagerLookup.getColor("activeCaption") to calculate a color that we can use
* in dockable frame's title pane. We will use UIManagerLookup.getColor("control") to calculate a color that we can use
* as background of JIDE component. Most L&Fs will fill those UIDefaults. However in Synth L&F, those UIDefaults may or
* may not have a valid value. You will end up with NPE later in the code when you call installJideExtension. In this
* case, you can add those extra UIDefaults in UIDefaultsInitializer. We will call it before installJideExtension is
* called so that those UIDefaults are there ready for us to use. This is how added support to GTK L&F and Synthetica
* L&F.
* <p/>
* After you create your own UIDefaultsCustomizer or Initializer, you can call {@link
* #addUIDefaultsCustomizer(com.jidesoft.plaf.LookAndFeelFactory.UIDefaultsCustomizer)} or {@link
* #addUIDefaultsInitializer(com.jidesoft.plaf.LookAndFeelFactory.UIDefaultsInitializer)} which will make the customizer
* or the initializer triggered all the times. If you only want it to be used for a certain L&F, you should use {@link
* #registerDefaultCustomizer(String, String)} or {@link #registerDefaultInitializer(String, String)}.
* <p/>
* By default, we also use UIDefaultsCustomizer and UIDefaultsInitializer internally to provide support for non-standard
* L&Fs. However we look into the classes under "com.jidesoft.plaf" package for default customizers and initializers.
* For example, for PlasticXPLookAndFeel, the corresponding customizer is "oom.jidesoft.plaf.plasticxp.PlasticXPCustomizer".
* We basically take the L&F name "PlasticXP", append it after "com.jidesoft.plaf" using lower case to get package name,
* take the L&F name, append with "Customizer" to get the class name. We will look at PlasticXPLookAndFeel's super class
* which is PlasticLookAndFeel. The customizer corresponding to PlasticLookAndFeel is
* "com.jidesoft.plaf.plastic.PlasticCustomizer". This searching process continues till we find all super classes of a
* L&F. Then we start from its top-most super class and call the customizers one by one, if it is there. The
* src-plaf.jar or src-plaf-jdk7.jar contain some of these customizers. You could use this naming pattern to create the
* customizers so that you don't need to register them explicitly.
* <p/>
* {@link #installJideExtension()} method will only add the additional UIDefaults to current ClassLoader. If you have
* several class loaders in your system, you probably should tell the UIManager to use the class loader that called
* <code>installJideExtension</code>. Otherwise, you might some unexpected errors. Here is how to specify the class
* loaders.
* <code><pre>
* UIManager.put("ClassLoader", currentClass.getClassLoader()); // currentClass is the class where the code is.
* LookAndFeelFactory.installDefaultLookAndFeelAndExtension(); // or installJideExtension()
* </pre></code>
