我试图用新的自定义对话框替换JOptionPane的使用，这就是我所做的：
SIMessage sm=new SIMessage(this, "Attention", SIMessage.TypeMessage.WARNING_MESSAGE,"You need to change ...");
callMethode2();
然后我打电话给：
$array = array(
'1'=>"Cat",
'2' => 'Horse',
'3' => 'Zebra',
'4' => 'Bear',
'5' => 'Dog',
);
问题是它在显示任何对话之前执行对Methode2的调用，而它应该在继续之前强制用户做出响应。 我看到一个空窗口与callMethod2生成的窗口并排！所以有什么问题？
答案 0 :(得分：2)
您应该为Dialog设置模态。
模态窗口是从属于应用程序主窗口的图形控件元素。它创建一个模式，禁用主窗口，但使用模态窗口作为前面的子窗口使其保持可见。用户必须先与模态窗口进行交互才能返回父应用程序。
因此，在初始化时设置对话框的模态标志。
setModal(True)
修改 我不知道你的代码中究竟发生了什么变化，但下面的代码对我来说很合适：
