从 swingWorker 处理框架

actually i have called the swing worker from a frame (Suppose) A.. in the swing worker class in do-in-Background method i have certain db queries and i am calling frame B too.. in the done() method however i want to dispose the frame A.. how can i do that..? i cannot write dispose() in frame A class because that results in disposing of frame before the new frame(frame B) is visible... Please help!!

class frameA extends JFrame{
public frameA(){
//done some operations..
SwingWorker worker=new Worker();
       worker.execute();

}
public static void main(string[] args){
  new frameA();
}

}

在工人阶级中

class Worker extends SwingWorker<Void, String> {



public Worker() {
    super();


}

//Executed on the Event Dispatch Thread after the doInBackground method is finished
@Override
protected void done() {
    //want to dispose the frameA here..


}

@Override
protected Void doInBackground() throws Exception {
    // some db queries
  new frameB().setVisible(true);  
  // call to frameb
}

推荐答案

1. SwingWorker 的done() 方法通常被覆盖以显示最终结果.之上doInBackground() 完成后，SwingWorker 自动调用done() 在 EDT 中.所以把你框架的不可见和可见代码放在这个函数中.

class Worker extends SwingWorker<Void, String> {

  JFrame frameA;

  public Worker(JFrame frameA) {
    this.frameA = frameA;

  }

  @Override
  protected void done() {
    frameA.dispose();
    new frameB().setVisible(true); 

  }
  //other code
}
