覆盖默认外观Java
我想覆盖java的外观。 我只是想以不同的方式显示按钮。
我想要Windows外观的所有function，但只有不同的按钮。 我希望你明白我的观点。
Color color = new Color(220, 220, 220, 200); UIManager.put("OptionPane.background", color); UIManager.put("Panel.background", color); UIManager.put("Button.foreground", new Color(255, 255, 255, 255)); List gradients = new ArrayList(5); gradients.add(0.00f); gradients.add(0.00f); gradients.add(new Color(0xC1C1C1)); gradients.add(new Color(0xFFFFFF)); gradients.add(new Color(0x5C5D5C)); UIManager.put("Button.gradient", gradients); UIManager.put("Button.highlight",Color.RED); UIManager.setLookAndFeel(com.sun.java.swing.plaf.windows.WindowsLookAndFeel); 也告诉我如何使圆形的JtabbedPane ???
好吧，如果您在应用Windows LnF之前更新LnF信息，则您没有机会将它们考虑在内:-)
我建议您首先加载Windows LnF来反转代码，然后只更新按钮。 但要注意，通过这样做，你将改变所有按钮的外观，而不仅仅是你的。

称之为自定义GUI类
import java.awt.Color; import javax.swing.BorderFactory; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JTabbedPane; import javax.swing.UIManager; public class TestPSTabbedPaneUI { public static void main(String[] args) { try { UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel"); } catch (Exception exc) { exc.printStackTrace(); } JFrame vFrame = new JFrame(); vFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); vFrame.setSize(200, 200); JTabbedPane vTab = new JTabbedPane(); vTab.setUI(new AizCustomGUI() ); vTab.add("One", new JPanel()); JPanel vPanel2 = new JPanel(); vPanel2.setBorder(BorderFactory.createLineBorder(Color.BLACK,2)); vTab.add("Two", vPanel2); vTab.add("Three", new JButton("three")); vFrame.getContentPane().add(vTab); vFrame.setTitle("Tabs Example"); vFrame.show(); } }
您始终可以inheritanceWindowsLookAndFeel，并覆盖initialize（），initClassDefaults（），initComponentDefaults（）和initSystemColorDefaults（）以根据需要执行操作。
