Nimbus L＆F – 改变进度条的背景颜色

我正在使用Netbeans Editor开发一个带有Java的GUI应用程序。 我在JFrame中添加了一个简单的进度条。 我正在使用JDK7开发项目

我想将背景颜色从默认橙色更改为个人颜色。 我已经尝试了所有属性的颜色变化但是当我运行程序时颜色仍然相同。

我已经尝试过使用ProgressBar1.setBackground（new java.awt.Color（0,204,255））;

和

UIManager.put("ProgressBar.background", Color.YELLOW); UIManager.put("ProgressBar.foreground", Color.MAGENTA); UIManager.put("ProgressBar.selectionBackground", Color.red); UIManager.put("ProgressBar.selectionForeground", Color.green); 

相同的结果…..背景总是橙色

这是我的测试项目的代码

 public class Frame extends javax.swing.JFrame { public Frame() { initComponents(); } @SuppressWarnings("unchecked") //  private void initComponents() { jProgressBar1 = new javax.swing.JProgressBar(); setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); jProgressBar1.setBackground(new java.awt.Color(0, 204, 255)); jProgressBar1.setValue(75); javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane()); getContentPane().setLayout(layout); layout.setHorizontalGroup( layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGroup(layout.createSequentialGroup() .addContainerGap() .addComponent(jProgressBar1, javax.swing.GroupLayout.DEFAULT_SIZE, 380, Short.MAX_VALUE) .addContainerGap()) ); layout.setVerticalGroup( layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGroup(layout.createSequentialGroup() .addContainerGap() .addComponent(jProgressBar1, javax.swing.GroupLayout.PREFERRED_SIZE, 73, javax.swing.GroupLayout.PREFERRED_SIZE) .addContainerGap(javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)) ); pack(); }//  public static void main(String args[]) { 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 ex) { java.util.logging.Logger.getLogger(Frame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex); } catch (InstantiationException ex) { java.util.logging.Logger.getLogger(Frame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex); } catch (IllegalAccessException ex) { java.util.logging.Logger.getLogger(Frame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex); } catch (javax.swing.UnsupportedLookAndFeelException ex) { java.util.logging.Logger.getLogger(Frame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex); } // /* * Create and display the form */ java.awt.EventQueue.invokeLater(new Runnable() { public void run() { new Frame().setVisible(true); } }); } // Variables declaration - do not modify private javax.swing.JProgressBar jProgressBar1; // End of variables declaration } 

这是您启动代码进度条时的结果http://sofzh.miximages.com/java/21508073887-o​​rig.jpg

橙色……

编辑使用以下代码

 UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled].backgroundPainter", new FillPainter(Color.MAGENTA)); UIManager.getLookAndFeelDefaults().put("ProgressBar[Disabled].backgroundPainter", new FillPainter(Color.MAGENTA)); UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled+Indeterminate].progressPadding", new FillPainter(Color.ORANGE)); UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled].foregroundPainter", new FillPainter(Color.GREEN)); UIManager.getLookAndFeelDefaults().put("ProgressBar[Disabled].foregroundPainter", new FillPainter(Color.GREEN)); UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled+Finished].foregroundPainter", new FillPainter(Color.GREEN)); UIManager.getLookAndFeelDefaults().put("ProgressBar[Disabled+Finished].foregroundPainter", new FillPainter(Color.GREEN)); UIManager.getLookAndFeelDefaults().put("ProgressBar[Disabled+Indeterminate].foregroundPainter", new FillPainter(Color.GREEN)); UIManager.getLookAndFeelDefaults().put("ProgressBar[Enabled+Indeterminate].foregroundPainter", new FillPainter(Color.GREEN)); ` 

在此之后

 javax.swing.UIManager.setLookAndFeel(info.getClassName()); 

我成功地改变了背景的颜色。 但现在颜色是“平淡的”，没有像橙色那样的渐变。

是否可以改变颜色与原始颜色相同的效果？

Answer 1

1. 也许（ Color和Font ）问题谈论Nimbus Look and Feel

2. 必须检查这个post

3. 的价值

ProgressBar [Disabled + Finished] .foregroundPainter ProgressBar [Disabled + Indeterminate] .foregroundPainter
ProgressBar [Disabled] .backgroundPainter ProgressBar [Disabled] .foregroundPainter ProgressBar [Enabled + Finished] .foregroundPainter ProgressBar [Enabled + Indeterminate] .foregroundPainter ProgressBar [Enabled + Indeterminate] .progressPadding ProgressBar [Enabled] .backgroundPainter ProgressBar [Enabled] .foregroundPainter

。 4.也许最简单的方法是将nimbusOrange从Nimbus default s的顶部更改，但这种变化无处不在，

例如，通过更改的Control Color向GUI输出有趣的输出

UIManager.getLookAndFeelDefaults（）。put（“nimbusOrange”，（new Color（127,255,191）））;

。 5.例如

 import java.awt.BorderLayout; import java.awt.Color; import java.awt.EventQueue; import java.awt.Graphics2D; import javax.swing.*; public class MyPopupWithNimbus { public MyPopupWithNimbus() { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(200, 200); JPanel panel = new JPanel(new BorderLayout()); panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10)); JList list = new JList(); panel.add(list); JProgressBar progress = new JProgressBar(); progress.setStringPainted(true); progress.setString("60 pct"); progress.setValue(60); frame.add(panel); frame.add(progress, BorderLayout.SOUTH); JPopupMenu menu = new JPopupMenu(); menu.add(new JMenuItem("A")); menu.add(new JMenuItem("B")); menu.add(new JMenuItem("C")); JMenu jmenu = new JMenu("D"); jmenu.add(new JMenuItem("E")); menu.add(jmenu); frame.setVisible(true); menu.show(frame, 50, 50); } public static void main(String[] args) { try { for (UIManager.LookAndFeelInfo laf : UIManager.getInstalledLookAndFeels()) { if ("Nimbus".equals(laf.getName())) { UIManager.setLookAndFeel(laf.getClassName()); UIManager.getLookAndFeelDefaults().put("nimbusOrange", (new Color(127, 255, 191))); UIManager.getLookAndFeelDefaults().put("PopupMenu[Enabled].backgroundPainter", new FillPainter(Color.ORANGE)); } } } catch (Exception e) { e.printStackTrace(); } EventQueue.invokeLater(new Runnable() { @Override public void run() { MyPopupWithNimbus aa = new MyPopupWithNimbus(); } }); } } class FillPainter implements Painter { private final Color color; FillPainter(Color c) { color = c; } @Override public void paint(Graphics2D g, JComponent object, int width, int height) { g.setColor(color); g.fillRect(0, 0, width - 1, height - 1); } } 

Answer 2

这就是我在目前开发的应用程序中所做的

 ColorUIResource colorResource = new ColorUIResource(Color.red.darker().darker()); UIManager.put("nimbusOrange",colorResource); 

这简单地改变了默认的橙色，用更吸引眼球的东西来改变它。
