Synth does not provide a default look. In      order to use Synth you need to specify a      <a href="doc-files/synthFileFormat.html">file</a>, or       provide a {@link      javax.swing.plaf.synth.SynthStyleFactory}. Both       configuration options require an       understanding of the synth architecture, which is described      below, as well as an understanding of Swing's architecture.    </p>    <p>      Unless otherwise specified null is not a legal value to any of      the methods defined in the synth package and if passed in will      result in a <code>NullPointerException</code>.           <h2>Synth</h2>    <p>      Each {@link javax.swing.plaf.ComponentUI} implementation in Synth associates      itself with one {@link      javax.swing.plaf.synth.SynthStyle} per {@link      javax.swing.plaf.synth.Region}, most      <code>Components</code> only have one <code>Region</code> and      therefor only one <code>SynthStyle</code>.      <code>SynthStyle</code>      is used to access all style related properties: fonts, colors      and other <code>Component</code> properties. In addition      <code>SynthStyle</code>s are used to obtain       {@link javax.swing.plaf.synth.SynthPainter}s for painting the background, border,      focus and other portions of a <code>Component</code>. The <code>ComponentUI</code>s obtain      <code>SynthStyle</code>s from a      {@link javax.swing.plaf.synth.SynthStyleFactory}.      A <code>SynthStyleFactory</code>      can be provided directly by way of       {@link javax.swing.plaf.synth.SynthLookAndFeel#setStyleFactory(javax.swing.plaf.synth.SynthStyleFactory)},      or indirectly by way of      {@link javax.swing.plaf.synth.SynthLookAndFeel#load}. The      following example uses the <code>SynthLookAndFeel.load()</code>      method to configure a <code>SynthLookAndFeel</code> and sets it      as the current look and feel:    </p>    <div class="example">      <pre>  SynthLookAndFeel laf = new SynthLookAndFeel();  laf.load(MyClass.class.getResourceAsStream("laf.xml"), MyClass.class);  UIManager.setLookAndFeel(laf);      </pre>    </div>    <p>      Many <code>JComponent</code>s are broken down into smaller      pieces and identified by the type safe enumeration in      {@link javax.swing.plaf.synth.Region}. For example, a <code>JTabbedPane</code>      consists of a <code>Region</code> for the      <code>JTabbedPane</code> ({@link      javax.swing.plaf.synth.Region#TABBED_PANE}), the content      area ({@link      javax.swing.plaf.synth.Region#TABBED_PANE_CONTENT}), the      area behind the tabs ({@link      javax.swing.plaf.synth.Region#TABBED_PANE_TAB_AREA}), and the      tabs ({@link      javax.swing.plaf.synth.Region#TABBED_PANE_TAB}). Each      <code>Region</code> of each      <code>JComponent</code> will have a      <code>SynthStyle</code>. This allows       you to customize individual pieces of each region of each      <code>JComponent</code>.    <p>      Many of the Synth methods take a {@link javax.swing.plaf.synth.SynthContext}. This       is used to provide information about the current      <code>Component</code> and includes: the      {@link javax.swing.plaf.synth.SynthStyle} associated with the current      {@link javax.swing.plaf.synth.Region}, the state of the <code>Component</code>      as a bitmask (refer to {@link      javax.swing.plaf.synth.SynthConstants} for the valid      states), and a {@link javax.swing.plaf.synth.Region} identifying the portion of       the <code>Component</code> being painted.    <p>      All text rendering by non-<code>JTextComponent</code>s is      delegated to a {@link      javax.swing.plaf.synth.SynthGraphicsUtils}, which is      obtained using the {@link javax.swing.plaf.synth.SynthStyle} method      {@link javax.swing.plaf.synth.SynthStyle#getGraphicsUtils}. You can      customize text rendering       by supplying your own {@link javax.swing.plaf.synth.SynthGraphicsUtils}.     </p>     <h2>Notes on specific components</h2>     <h3>JTree</h3>    <p>      Synth provides a region for the cells of a tree:      <code>Region.TREE_CELL</code>.  To specify the colors of the      renderer you'll want to provide a style for the      <code>TREE_CELL</code> region.  The following illustrates this:<pre>  &lt;style id="treeCellStyle">    &lt;opaque value="TRUE"/>    &lt;state>      &lt;color value="WHITE" type="TEXT_FOREGROUND"/>      &lt;color value="RED" type="TEXT_BACKGROUND"/>    &lt;/state>    &lt;state value="SELECTED">      &lt;color value="RED" type="TEXT_FOREGROUND"/>      &lt;color value="WHITE" type="BACKGROUND"/>    &lt;/state>  &lt;/style>  &lt;bind style="treeCellStyle" type="region" key="TreeCell"/></pre>    <p>      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:<pre>  &lt;style id="labelStyle">    &lt;opaque value="FALSE"/>  &lt;/style>  &lt;bind style="labelStyle" type="region" key="Label"/></pre>          <h3>JList and JTable</h3>    <p>      The colors that the renderers for JList and JTable use are      specified by way of the list and table Regions.  The following      XML fragment illustrates how to specify red on white, when      selected, and white on red when not selected:<pre>  &lt;style id="style">    &lt;opaque value="TRUE"/>    &lt;state>      &lt;color value="WHITE" type="TEXT_FOREGROUND"/>      &lt;color value="RED" type="TEXT_BACKGROUND"/>      &lt;color value="RED" type="BACKGROUND"/>    &lt;/state>    &lt;state value="SELECTED">      &lt;color value="RED" type="TEXT_FOREGROUND"/>      &lt;color value="WHITE" type="TEXT_BACKGROUND"/>    &lt;/state>  &lt;/style>  &lt;bind style="style" type="region" key="Table"/>  &lt;bind style="style" type="region" key="List"/></pre>  </body></html>
