一個JFrame中不停止其他框架的代碼

Question

當用戶點擊編輯按鈕，一個新的幀顯示給他們，當新框架被關閉，我想刷新線來執行，但問題是，刷新線是在關閉新框架之前執行......我使用NetBeans製作UI。

//If user clicks on edit button new frame will be shown to him 
EditUserFrame editUserFrame = new EditUserFrame(); 
Iterator itr = userList.iterator(); 
while(itr.hasNext()){ 
    user = (Users)itr.next(); 
    if((user.getF_name().equals(f_name) && user.getL_name().equals(l_name))){ 
     break; 
    } 
}//End of While Loop 
editUserFrame.setUserObj(user); 
editUserFrame.getExistingValues(); 
editUserFrame.setVisible(true); 
//I want this line to be executed when the editUserFrame is closed.. 
RefreshUserTable(); 

我想要像這樣的新框架可以使JOPtionPane中的圖片給出，就像你們建議的那樣。

Answer 1

可以使用

'editUserFrame.addWindowListener(new WindowAdapter() 
{ 
    public void windowClosed(WindowEvent e){ 
    //call your method from here 
     RefreshUserTable(); 
    } 
};' 

希望這有助於

你想用某種形式的模態對話框。對話框旨在在程序顯示位置「暫停」程序的執行。

你也可以使用一個JOptionPane，使您更容易一樣，因爲他們可以用不同的按鈕/選項比較容易進行配置。退房JOptionPane Features與示例更新的概述
