Java如何创建JLabel组件？
package org.nhooo.example.swing;
import javax.swing.*;
import java.awt.*;
public class JLabelDemo extends JFrame {
public JLabelDemo() throws HeadlessException {
initialize();
}
private void initialize() {
setSize(150, 300);
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
setLayout(new FlowLayout());
//用文本创建一些JLabel并定义水平对齐方式
JLabel label1 = new JLabel("Username :", JLabel.RIGHT);
JLabel label2 = new JLabel("Password :", JLabel.RIGHT);
JLabel label3 = new JLabel("Confirm Password :", JLabel.RIGHT);
JLabel label4 = new JLabel("Remember Me!", JLabel.LEFT);
JLabel label5 = new JLabel("Hello, Anybody There?", JLabel.CENTER);
//设置标签5的垂直对齐方式，并为其设置工具提示
label5.setVerticalAlignment(JLabel.TOP);
label5.setToolTipText("I have a tool tip with me!");
getContentPane().add(label1);
getContentPane().add(label2);
getContentPane().add(label3);
getContentPane().add(label4);
getContentPane().add(label5);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new JLabelDemo().setVisible(true);
}
});
}
}
