java - 将事件处理添加到 Jframe 对话框

Question

所以我有以下代码来制作一个快速弹出框，通知我的用户程序已完成运行。我想在用户单击“确定”后处理一些额外的事件，特别是我想关闭一些驱动程序和 sql 连接。我怎样才能做到这一点？

这是制作 jframe 的代码

javax.swing.JFrame optionFrame = new javax.swing.JFrame();
     JOptionPane.showMessageDialog(optionFrame, "Tests Complete. Screenshots and Results can be found at C://Features");
     optionFrame.toFront();
     optionFrame.repaint();
     this.dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING));

Answer 1

只需在显示对话框后立即执行此操作，但在 this.dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING));

同时删除该部分:

 optionFrame.toFront();
 optionFrame.repaint();

这一行(消息对话框弹出窗口):

 JOptionPane.showMessageDialog(optionFrame, "Tests Complete. Screenshots and Results can be found at C://Features");

将保持调用它的线程，直到用户单击“确定”或关闭弹出窗口，无需执行任何额外操作，此行之后的任何代码都将在弹出窗口消失后执行。

根据您的示例，它可能是:

 ...
 JOptionPane.showMessageDialog(optionFrame, "Tests Complete. Screenshots and Results can be found at C://Features");
 // do your clean-up work here (probably invoke some clean up service method)
 this.dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING));
