我有一个主要的班级:

public class Main extends JFrame {
  public static void main(String args[]) {
 SwingUtilities.invokeLater(new Runnable() {
       public void run() {
       Main m = new Main();
       m.initGUI();
      }
 });
 public void initGUI() {
   //add components for this JFrame
   //add JPanel with table
   //etc..
   this.pack();
   this.setLocationRelativeTo(null);
   this.setVisible(true);
  }


}

然后我有一个扩展JPanel的类:

class CTable extends JPanel {
  JTable table;
   public void initGUI() {
  //add components, table to JPanel etc...
  //action listeners to table
 }
 public void handleTableRowOnClick(String data) {
   InfoDialog d = new InfoDialog(data);
   //HERE IS MY PROBLEM
   //do something else here (THIS SHOULD EXECUTE BUT IT DOESN'T) such as:
   String test = "test"
   //(IT ONLY EXECUTES AFTER I CLOSE THE DIALOG)
    //and I need the ModalityType.APPLICATION_MODAL functionality
 }
}


然后我有另一堂课:

class InfoDialog extends JDialog {
  JComboBox cb;
  String data;
   public void initGUI() {
    //add components such as JComboBox
    //etc...
    this.setModalityType(ModalityType.APPLICATION_MODAL);
    this.setTitle("test");
    this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
    this.pack();
    this.setLocationRelativeTo(null);
    this.setVisible(true);
  }
  public InfoDialog(String data) {
   this.data = data;
   this.initGUI();
  }

}


我的问题是在这种情况下确保InfoDialog实例在同一事件分配线程(EDT)中的最佳方法是什么?

感谢您的任何答复。

最佳答案

最好的解决方案是在创建对话框之前检查EventQueue.isDispatchingThread

public void handleTableRowOnClick(final String data) {
    Runnable runner = new Runnable() {
        public void run() {
            InfoDialog d = new InfoDialog(data);
        }
    }
    if (EventQueue.isDispatchingThread()) {
        runner.run();
    } else {
        EventQueue.invokeLater(runner);
    }
}


就像我在上一个问题中所说的那样,调用者应该负责确保代码(而不是组件)正确执行。
