创建自定义 UI 组件

创建您自己的可重用自定义 UI 组件，以在 App 中使用

创建您自己的自定义 UI 组件，以在您的 App 中使用或与其他人共享。您可以使用自定义组件来扩展现有 UI 组件功能，将大型 App 分解为独立且可维护的部件，并为用户设计界面，以便在多个 App 中自定义和重用某个组件。在 App 设计工具中以交互方式创建自定义组件，或通过创建 ComponentContainer 基类的子类以编程方式创建自定义组件。在这两种情况下，您都可以将组件配置为在使用 App 设计工具创建的 App 中以交互方式使用。

类

matlab.ui.componentcontainer.ComponentContainer 用于开发自定义 UI 组件对象的基类 (自 R2020b 起)

方法

`setup`	设置组件容器子类的实例
`update`	设置属性后更新 UI 组件容器子类的实例

函数

`appdesigner.customcomponent.configureMetadata`	配置在 App 设计工具中使用的自定义 UI 组件 (自 R2021a 起)
`appdesigner.customcomponent.removeMetadata`	从 App 设计工具中删除自定义 UI 组件 (自 R2021a 起)
