问题描述

示例现在我有一个包含 jtable 显示所有客户信息的主框架，并且有一个创建按钮来打开一个新的 JFrame，允许用户创建新客户.我不希望用户可以打开多个创建框架.任何 Swing 组件或 API 都可以做到这一点?或者如何禁用主框架?像 JDialog 这样的东西.

Example now I have a main frame contains jtable display all the customer information, and there was a create button to open up a new JFrame that allow user to create new customer. I don't want the user can open more than one create frame. Any swing component or API can do that? or how can disabled the main frame? Something like JDialog.

推荐答案

我建议您将新客户对话框设为模态 JDialog，这样您就不允许其他对话框/框架输入您的应用程序可见时.查看modality 教程了解详情.

I would suggest that you make your new customer dialog a modal JDialog so that you do not allow input from other dialogs/frames in your app while it is visible. Take a look at the modality tutorial for details.
