覆盖Java的默认外观 [英] Override default look and feel Java
本文介绍了覆盖Java的默认外观的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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 Look and Feel的所有功能，但只需要不同的按钮.希望你明白我的意思.
I want to override java look and feel. I just want to show the buttons differently.
I want all the features of Windows Look and Feel but only buttons differently. I hope you get my point.
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<Object> gradients = new ArrayList<Object>(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);
还告诉我 如何将JtabbedPane制成圆形?
ALSO TELL ME How to make JtabbedPane in Round shape???

调用您的自定义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();
}
}
