     laf.load(MyClass.class.getResourceAsStream("laf.xml"), MyClass.class);
     UIManager.setLookAndFeel(laf);
 

Many JComponents are broken down into smaller pieces and identified by the type safe enumeration in Region. For example, a JTabbedPane consists of a Region for the JTabbedPane(Region.TABBED_PANE), the content area (Region.TABBED_PANE_CONTENT), the area behind the tabs (Region.TABBED_PANE_TAB_AREA), and the tabs (Region.TABBED_PANE_TAB). Each Region of each JComponent will have a SynthStyle. This allows you to customize individual pieces of each region of each JComponent.

Many of the Synth methods take a SynthContext. This is used to provide information about the current Component and includes: the SynthStyle associated with the current Region, the state of the Component as a bitmask (refer to SynthConstants for the valid states), and a Region identifying the portion of the Component being painted.

All text rendering by non-JTextComponents is delegated to a SynthGraphicsUtils, which is obtained using the SynthStyle method SynthStyle.getGraphicsUtils(javax.swing.plaf.synth.SynthContext). You can customize text rendering by supplying your own SynthGraphicsUtils.

Notes on specific components

JTree

   <style id="treeCellStyle">
     <opaque value="TRUE"/>
     <state>
       <color value="WHITE" type="TEXT_FOREGROUND"/>
       <color value="RED" type="TEXT_BACKGROUND"/>
     </state>
     <state value="SELECTED">
       <color value="RED" type="TEXT_FOREGROUND"/>
       <color value="WHITE" type="BACKGROUND"/>
     </state>
   </style>
   <bind style="treeCellStyle" type="region" key="TreeCell"/>
 

This specifies a color combination of red on white, when selected, and white on red when not selected. To see the background you need to specify that labels are not opaque. The following XML fragment does that:

   <style id="labelStyle">
     <opaque value="FALSE"/>
   </style>
   <bind style="labelStyle" type="region" key="Label"/>
 

JList and JTable

   <style id="style">
     <opaque value="TRUE"/>
     <state>
       <color value="WHITE" type="TEXT_FOREGROUND"/>
       <color value="RED" type="TEXT_BACKGROUND"/>
       <color value="RED" type="BACKGROUND"/>
     </state>
     <state value="SELECTED">
       <color value="RED" type="TEXT_FOREGROUND"/>
       <color value="WHITE" type="TEXT_BACKGROUND"/>
     </state>
   </style>
   <bind style="style" type="region" key="Table"/>
   <bind style="style" type="region" key="List"/>
