添加事件處理到Jframe對話框

Question

所以我有以下代碼來創建一個快速彈出框，通知我的用戶程序已經完成運行。一旦用戶點擊確定，我想處理一些額外的事件，特別是我想關閉一些驅動程序和一個sql連接。我怎樣才能做到這一點？

下面的代碼，以使得JFrame中

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

只要做到這一點，你顯示對話框之後，但this.dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING));前

還能去除部分：

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

這條線（消息對話框彈出）：

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

將持有線程調用它，直到用戶單擊確定或關閉彈出窗口，不需要做任何額外的事情，任何代碼後這行將在彈出消失後執行。

根據您的例子則可能是：

... 
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));
