I would like to apply my own close and minimize buttons. Is there any way to change the JFrame design?

推荐答案

诀窍在于 PLAF 和 setDefaultLookAndFeelDecorated(true) (指定窗口装饰).

例如

import java.awt.BorderLayout; import javax.swing.*; public class FrameCloseButtonsByLookAndFeel { FrameCloseButtonsByLookAndFeel() { String[] names = { UIManager.getSystemLookAndFeelClassName(), UIManager.getCrossPlatformLookAndFeelClassName() }; for (String name : names) { try { UIManager.setLookAndFeel(name); } catch (Exception e) { e.printStackTrace(); } // very important to get the window decorations. JFrame.setDefaultLookAndFeelDecorated(true); JFrame f = new JFrame(UIManager.getLookAndFeel().getName()); f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); JPanel gui = new JPanel(new BorderLayout()); f.setContentPane(gui); JTree tree = new JTree(); tree.setVisibleRowCount(4); gui.add(tree, BorderLayout.LINE_START); gui.add(new JScrollPane(new JTextArea(3,15))); JToolBar toolbar = new JToolBar(); gui.add(toolbar, BorderLayout.PAGE_START); for (int ii=1; ii<5; ii++) { toolbar.add(new JButton("Button " + ii)); if (ii%2==0) { toolbar.addSeparator(); } } f.pack(); f.setLocationByPlatform(true); f.setVisible(true); } } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { new FrameCloseButtonsByLookAndFeel(); } }); } }
