ContentSwitcher

!!! tip "Added in version 0.14.0"

A widget for containing and switching display between multiple child widgets.

• Focusable
• Container

Example

The example below uses a ContentSwitcher in combination with two Buttons to create a simple tabbed view. Note how each Button has an ID set, and how each child of the ContentSwitcher has a corresponding ID; then a Button.Clicked handler is used to set ContentSwitcher.current to switch between the different views.

1. A `Horizontal` to hold the buttons, each with a unique ID.
2. This button will select the `DataTable` in the `ContentSwitcher`.
3. This button will select the `Markdown` in the `ContentSwitcher`.
4. Note that the initial visible content is set by its ID, see below.
5. When a button is pressed, its ID is used to switch to a different widget in the `ContentSwitcher`. Remember that IDs are unique within parent, so the buttons and the widgets in the `ContentSwitcher` can share IDs.

When the user presses the "Markdown" button the view is switched:
