With each Swing component it associates a foreground and a 37 background {@code Painter}, and there may be several painters for different 38 component states. 39 40 <p>Nimbus allows customizing many of its properties, including painters, by 41 altering the {@link javax.swing.UIDefaults} table. Here's an example: 42 <pre> 43 UIManager.put("ProgressBar.tileWidth", myTileWidth); 44 UIManager.put("ProgressBar[Enabled].backgroundPainter", myBgPainter); 45 UIManager.put("ProgressBar[Enabled].foregroundPainter", myFgPainter); 46 </pre> 47 48 <p>Per-component customization is also possible. When rendering a component, 49 Nimbus checks its client property named "Nimbus.Overrides". The value of this 50 property should be an instance of {@code UIDefaults}. Settings from that table 51 override the UIManager settings, but for that particular component instance 52 only. An optional client property, "Nimbus.Overrides.InheritDefaults" of type 53 Boolean, specifies whether the overriding settings should be merged with 54 default ones ({@code true}), or replace them ({@code false}). By default they 55 are merged: 56 <pre> 57 JProgressBar bar = new JProgressBar(); 58 UIDefaults overrides = new UIDefaults(); 59 overrides.put("ProgressBar.cycleTime", 330); 60 ... 61 bar.putClientProperty("Nimbus.Overrides", overrides); 62 bar.putClientProperty("Nimbus.Overrides.InheritDefaults", false); 63 </pre> 64 65 <p>Colors in Nimbus are derived from a core set of 66 <a href="doc-files/properties.html#primaryColors">primary colors</a>. There are also 67 <a href="doc-files/properties.html#secondaryColors">secondary colors</a>, which are 68 derived from primary ones, but serve themselves as base colors for other 69 derived colors. The derivation mechanism allows for runtime customization, 70 i.e. if a primary or secondary color is changed, all colors that are derived 71 from it are automatically updated. The method 72 {@link javax.swing.plaf.nimbus.NimbusLookAndFeel#getDerivedColor(java.lang.String, float, float, float, int, boolean)} 73 may be used to create a derived color. 74 75 <p>These classes are designed to be used while the 76 corresponding <code>LookAndFeel</code> class has been 77 installed 78 (<code>UIManager.setLookAndFeel(new <i>XXX</i>LookAndFeel())</code>). 79 Using them while a different <code>LookAndFeel</code> is installed 80 may produce unexpected results, including exceptions. 81 Additionally, changing the <code>LookAndFeel</code> 82 maintained by the <code>UIManager</code> without updating the 83 corresponding <code>ComponentUI</code> of any 84 <code>JComponent</code>s may also produce unexpected results, 85 such as the wrong colors showing up, and is generally not 86 encouraged. 87 88 <p><strong>Note:</strong> 89 Most of the Swing API is <em>not</em> thread safe. 90 For details, see 91 <a href="http://docs.oracle.com/javase/tutorial/uiswing/concurrency/index.html" 92 target="_top">Concurrency in Swing</a>, 93 a section in 94 <em><a href="http://docs.oracle.com/javase/tutorial/" 95 target="_top">The Java Tutorial</a></em>. 96 97 @since 1.7 98 @serial exclude 99 100 </body> 101 </html>
