JFrame 和 JDialog 有什么区别?

为什么我们不能将 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 是一个带有普通按钮(可选)和装饰的普通窗口.另一边的 JDialog 没有最大化和最小化按钮，通常使用 JOptionPane 静态方法创建，并且更适合使它们成为模态(它们阻止其他组件直到它们已关闭).

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).

但两者都继承自 Window，因此它们共享很多功能.

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