App 构建组件

App 设计工具和 UI 图窗支持大量组件，可用于设计功能齐全的现代化应用程序。下表列出了可用的组件。

  • 常用组件 - 包括响应交互的组件，如按钮、滑块、下拉列表和树。

  • 坐标区 - 包括用于创建绘图以进行数据可视化和探查的坐标区。

  • 容器和图窗工具 - 包括用于对组件分组的面板和选项卡，还包括菜单栏。

  • 仪表组件 - 包括用于可视化状态的仪表和信号灯，以及用于选择输入参数的旋钮和开关。

  • 可扩展组件 - 包括您创建的自定义 UI 组件。与第三方库对接以显示小组件或数据可视化等内容。

  • 工具箱组件 - 包括工具箱的 UI 组件。需要安装相应的工具箱并具备许可证。

所有组件都可以通过编程方式使用。App 设计工具组件库中还提供了大多数 UI 组件，您可以将它们拖放到画布上。要向使用 App 设计工具创建的 App 添加组件库中没有的组件，或要将组件动态添加到正在运行的 App，请参阅以编程方式向 App 设计工具添加 UI 组件。

在 App 设计工具中调用图形函数的工作流与通常在 MATLAB® 命令行中使用的工作流略有不同。有关如何在 App 设计工具中调用图形函数的详细信息，请参阅在 App 设计工具中显示图形。
