怎样让窗口始终在前

　　1,The upstair tell you a best way.
　　2,You can extends JWindow
　　override show() like this:
　　public void show()
　　{
　　super.show();
　　this.requestFocus();
　　}
　　and then add a window listener for
　　the focus lost event:
　　
　　addFocusListener (new Java.awt.event.FocusAdapter () {
　　public void focusLost (java.awt.event.FocusEvent evt) {
　　this.toFront();
　　}
　　}
　　);
　　It seems to work for me...
　　
　　3.You can also try to use thread, I recommend this way.
　　/**
　　* Call this from class consrUCtor
　　*/
　　public void initialize() {
　　TopThread top = new TopThread();
　　top.start();
　　}
　　
　　/**
　　* Keep JWindow on top (inner class)
　　*/
　　class TopThread extends Thread {
　　public void run() {
　　while(true) {
　　toFront();
　　/**
　　* Let 10 milliseconds for other code to execute
　　*/
　　try {
　　Thread.sleep(10);
　　}
　　catch(Exception e) {
　　// do what you wanna do
　　}
　　}
　　}
　　}
