在java中qq界面中怎么按enter键发送消息
方法一:
import java.awt.* ;
import javax.swing.* ;
import java.awt.event.*;
public class ButtonTest extends JFrame implements KeyListener{
private JButton b1 = new JButton("Click") ;
public ButtonTest(){
this.getContentPane().add(b1) ;
b1.addKeyListener(this) ;
this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
this.pack() ;
}
public void keyReleased(KeyEvent ke){
}
public void keyPressed(KeyEvent ke){
if(ke.getKeyChar() == ke.VK_ENTER){
System.out.println ("ok................") ;
}
}
public void keyTyped(KeyEvent ke){
}
public static void main(String[] args){
new ButtonTest().show() ;
}
