如何来让你的JFrame界面更好看
main方法里添加try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException e) {
e.printStackTrace();
}
图片我不会上传
源码也给你们
public class Test extends JFrame{
public Test() {
this.setTitle("测试");
this.setVisible(true);
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setLayout(null);
this.setSize(400, 300);
JButton button = new JButton("test");
button.setBounds(120, 110, 100, 30);
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(null, "Hello World");
}
});
this.add(button);
}
public static void main(String[] args) {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException e) {
e.printStackTrace();
}
new Test();
}
}
