关于JDialog的问题

Question

这样做好像不行，把延时放在Dialog的线程之外，然后再时间到了之后通知Dialog的线程区关闭对话框

Answer 1

public WaitingDialog() {
        super(MapView.parentFrame);
        setTitle("waiting...");
        pack();
        setModal(true);
        setResizable(false);  
        
        initPanel();
    }
下面的那个PACK（）；去掉试试。

Answer 4

Runnable接口的用法不太对
public class WaitingDialog extends JDialog implements Runnable {
...
private Thread waitThread = null;
public start() {
  if (waitThread == null) {
     waitThread = new Thread(this, "waitdialog");
     waitThread.start();
  }
}public void run() {
...
}
...
}
