Question

所以我不熟悉Netbeans和Swing GUI开发，我试图改变JFrame的外观。当我创建一个JFrame窗体时，Netbeans默认使它成为Nimbus主题。

我尝试更改为Windows主题（if ("Windows".equals(info.getName())) {）和Metal主题（if ("Metal".equals(info.getName())) {），并且它与这两个主题完美配合。

但是当我尝试将其更改为Dark Nimbus主题（if ("Dark Nimbus".equals(info.getName())) {）时，它无法正常工作。

我也试过做右键点击＆gt;预览设计＆gt; Dark Nimbus，是的，它按预期预览了Dark Nimbus主题。但是当我实际编译并运行程序时（通过单击播放按钮）不是。

有谁知道如何将主题改为＆＃34; Dark Nimbus＆＃34;？

以下是相关代码：

    /* Set the Nimbus look and feel */
    //<editor-fold defaultstate="collapsed" desc=" Look and feel setting code (optional) ">
    /* If Nimbus (introduced in Java SE 6) is not available, stay with the default look and feel.
     * For details see http://download.oracle.com/javase/tutorial/uiswing/lookandfeel/plaf.html 
     */
    try {
        for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
            if ("Dark Nimbus".equals(info.getName())) {
                javax.swing.UIManager.setLookAndFeel(info.getClassName());
                break;
            }
        }
    } catch (ClassNotFoundException ex) {
        java.util.logging.Logger.getLogger(TestGUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    } catch (InstantiationException ex) {
        java.util.logging.Logger.getLogger(TestGUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    } catch (IllegalAccessException ex) {
        java.util.logging.Logger.getLogger(TestGUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    } catch (javax.swing.UnsupportedLookAndFeelException ex) {
        java.util.logging.Logger.getLogger(TestGUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    }

我最近也有同样的担忧，我从Geertjan Wielenga 和Neil C Smith找到了这些极好的提示。所以你的问题的答案是：

public static void main(String[] args) {
  UIManager.put( "control", new Color( 128, 128, 128) );
  UIManager.put( "info", new Color(128,128,128) );
  UIManager.put( "nimbusBase", new Color( 18, 30, 49) );
  UIManager.put( "nimbusAlertYellow", new Color( 248, 187, 0) );
  UIManager.put( "nimbusDisabledText", new Color( 128, 128, 128) );
  UIManager.put( "nimbusFocus", new Color(115,164,209) );
  UIManager.put( "nimbusGreen", new Color(176,179,50) );
  UIManager.put( "nimbusInfoBlue", new Color( 66, 139, 221) );
  UIManager.put( "nimbusLightBackground", new Color( 18, 30, 49) );
  UIManager.put( "nimbusOrange", new Color(191,98,4) );
  UIManager.put( "nimbusRed", new Color(169,46,34) );
  UIManager.put( "nimbusSelectedText", new Color( 255, 255, 255) );
  UIManager.put( "nimbusSelectionBackground", new Color( 104, 93, 156) );
  UIManager.put( "text", new Color( 230, 230, 230) );
  try {
    for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
      if ("Nimbus".equals(info.getName())) {
          javax.swing.UIManager.setLookAndFeel(info.getClassName());
          break;
      }
    }
  } catch (ClassNotFoundException e) {
    e.printStackTrace();
  } catch (InstantiationException e) {
    e.printStackTrace();
  } catch (IllegalAccessException e) {
    e.printStackTrace();
  } catch (javax.swing.UnsupportedLookAndFeelException e) {
    e.printStackTrace();
  } catch (Exception e) {
    e.printStackTrace();
  }
  // Show your JFrame
}

代码在这种状态下运行得更好：

// Dark LAF
try {
    UIManager.setLookAndFeel(new NimbusLookAndFeel());
    UIManager.put("control", new Color(128, 128, 128));
    UIManager.put("info", new Color(128, 128, 128));
    UIManager.put("nimbusBase", new Color(18, 30, 49));
    UIManager.put("nimbusAlertYellow", new Color(248, 187, 0));
    UIManager.put("nimbusDisabledText", new Color(128, 128, 128));
    UIManager.put("nimbusFocus", new Color(115, 164, 209));
    UIManager.put("nimbusGreen", new Color(176, 179, 50));
    UIManager.put("nimbusInfoBlue", new Color(66, 139, 221));
    UIManager.put("nimbusLightBackground", new Color(18, 30, 49));
    UIManager.put("nimbusOrange", new Color(191, 98, 4));
    UIManager.put("nimbusRed", new Color(169, 46, 34));
    UIManager.put("nimbusSelectedText", new Color(255, 255, 255));
    UIManager.put("nimbusSelectionBackground", new Color(104, 93, 156));
    UIManager.put("text", new Color(230, 230, 230));
    SwingUtilities.updateComponentTreeUI(this);
} catch (UnsupportedLookAndFeelException exc) {
    System.err.println("Nimbus: Unsupported Look and feel!");
}
