将 JComponent 重置为默认值

问题描述

例如，如果组件是一个复选框，它必须设置为 false，或者它是一个文本字段，它必须清除文本.我正在尝试编写一种方法来重置 JPanel 中的所有组件.它必须像 HTML 表单中的重置功能一样工作.

For example, if component is a checkbox it must set to false, or it is a textfield it must be clear the text. I am trying to write a method for reset all components in a JPanel. It must work like reset function in HTML forms.

推荐答案

一种可能的解决方法是创建自定义重置函数.重新初始化面板(您的表单).

One possible workaround would be to create a custom reset function. Reinitialize the panel ( your form).

例如

void reset(){
    //recreate the form panel.
    formPanel = new FormPanel();
}

创建自定义类 FormPanel 来存储表单字段及其侦听器.

Create a custom class FormPanel to store the form fields and their listeners.

重新初始化面板组件会导致按照@Robin 的建议重新分配监听器的开销.

Re initializing the panel components would result in an overhead of reassigning the listeners as @Robin suggested.
