I have created one GUI in which I have used a JFrame. How should I make it Modal?
推荐答案
如果你想使窗口模式化,最好的办法是使用 JDialog 而不是 JFrame.查看在 Java 6 中引入 Modality API 的详细信息信息.还有教程.
Your best bet is to use a JDialog instead of a JFrame if you want to make the window modal. Check out details on the introduction of the Modality API in Java 6 for info. There is also a tutorial.
这里是一些示例代码,它将在 JDialog 中显示 JPanel 面板,它是 Frame parentFrame 的模态.除了构造函数之外,这遵循与打开 JFrame 相同的模式.
Here is some sample code which will display a JPanel panel in a JDialog which is modal to Frame parentFrame. Except for the constructor, this follows the same pattern as opening a JFrame.
final JDialog frame = new JDialog(parentFrame, frameTitle, true); frame.getContentPane().add(panel); frame.pack(); frame.setVisible(true);
