JFrame和JDialog有什么区别?

我们为什么不能将setDefaultCloseOperation(JDialog.EXIT_ON_CLOSE);用于JDialog?

Why can't we use setDefaultCloseOperation(JDialog.EXIT_ON_CLOSE); for a JDialog?

推荐答案

JFrame是一个普通窗口，带有其普通按钮(可选)和装饰.另一方面，JDialog没有最大化和最小化按钮，通常使用JOptionPane静态方法创建，并且更适合于使其成为模态的(它们会阻塞其他组件，直到它们被关闭).

JFrame is a normal window with its normal buttons (optionally) and decorations. JDialog on the other side does not have a maximize and minimize buttons and usually are created with JOptionPane static methods, and are better fit to make them modal (they block other components until they are closed).

但是两者都继承自Window，因此它们共享许多功能.

But both inherit from Window, so they share much functionality.
