如何禁用JPanel中的所有组件 [英] How to disable all components in a JPanel

问题描述

在我的JPanel中，我有很多组件，包括其他JPanel，JLabel，JTextAreas和JButton。因为我想实现一个教程模式，其中出现另一个窗口，我的主JPanel中的所有内容都被禁用，因为新窗口逐个解释每个'功能'...我想知道如何禁用我内部的所有组件原始JPanel。我知道你可以使用：

In my JPanel I have many components, including other JPanels, JLabels, JTextAreas, and JButtons. Becuase I want to implement a tutorial mode where another window appears and everything in my main JPanel is disabled as the new window explains each 'feature' one by one... I want a to know how to disable all the components that are inside my origiinal JPanel. I know you can use:

component.setEnabled(false);

但我不想为我的JPanel中的每个组件编写它。我想知道是否可以使用for循环或其他东西禁用JPanel中的所有组件？

But I don't want to write it for each component in my JPanel. I would like to know if it's possible to disable ALL components within my JPanel with a for loop or something?

注意：嵌套JPanels中也有组件，如命令将是

Note: There are also component in nested JPanels, like the order would be

主要JPanel --->嵌套JPanel --->组件

Main JPanel ---> Nested JPanel ---> Component

我也想要决赛组件也被禁用...

I also want the Final components to also be disabled...

谢谢！所有帮助表示赞赏！

推荐答案

查看已禁用面板，提供了几种解决方案。

Check out Disabled Panel for a couple of solutions.

一个使用禁用的GlassPane类型的方法，另一个使用递归方式禁用组件，同时跟踪组件的当前状态，以便以后可以正常启用。

One uses a disabled GlassPane type of approach and the other recursively disables components while keep track of the components current state so it can be enable properly later.
