I tried to run this, but for some reason it doesn't print test (however, the program closes). Does anyone have an idea what could be the problem?
frame.addWindowListener(new WindowAdapter() {
public void WindowClosing(WindowEvent e) {
System.out.println("test");
frame.dispose();
}
});
推荐答案
你可以使用addWindowListener:
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
// call terminate
}
});
参见 void windowClosing(WindowEvent e) 和 类 WindowAdapter 也是.
