有两个框体JFrame jf1,jf2
当jf2出现时jf1设为不可见;
当jf2关闭时jf1又可见了。求解答！
如何判断jf2已经关闭了？

加个监听不就完了
- Java code
Frame f = new Frame(); f.addWindowListener(new WindowListener() { @Override public void windowActivated(WindowEvent arg0) { // TODO Auto-generated method stub } @Override public void windowClosed(WindowEvent arg0) { // TODO Auto-generated method stub System.out.println("关闭"); } @Override public void windowClosing(WindowEvent arg0) { // TODO Auto-generated method stub } @Override public void windowDeactivated(WindowEvent arg0) { // TODO Auto-generated method stub } @Override public void windowDeiconified(WindowEvent arg0) { // TODO Auto-generated method stub } @Override public void windowIconified(WindowEvent arg0) { // TODO Auto-generated method stub } @Override public void windowOpened(WindowEvent arg0) { // TODO Auto-generated method stub } });

开启F2的时候 设置F1 visible = false
开启F1的时候 设置F2 visible = false

boolean flag标记一下。通过flag判断。
