Swing弹出窗口后如何使当前窗口(包括windows和java生成的)不丢失焦点import java.awt.Window;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;import javax.swing.JDialog;
import javax.swing.JFrame;public class Test extends JDialog implements Runnable{ public Test(){
}
@Override
public void run() {
// TODO Auto-generated method stub
this.setTitle("测试");
this.setVisible(true);
}
public static void main(String[] args){
int i=0;
while (i<5) {
Thread thread = new Thread(new Test());
thread.start();
i++;
}
}
}执行后当前主窗口和系统窗口都会失去焦点，而像QQ的右下角弹出消息就不会丢失焦点，如何改成像QQ这样的呢？
