Java swing去掉边框的代码如下
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
public class SwingDemo {
public static void main(String[] args) {
// TODO 自动生成的方法存根
JFrame jframe = new JFrame("Demo");
JButton button = new JButton("JB");
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
System.out.println("click JB");
}
});
//去掉按钮文字周围的焦点框
button.setFocusPainted(false);
jframe.getContentPane().add(button);
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jframe.setBounds(100, 100, 200, 136);
jframe.setVisible(true);
