Layout inheritance

You can derive a layout from an existing layout. This process is based on merging the information from the derived layout on top of the information that the base layout contains.

• For layouts defined as types, the base layout is the layout of the base type (if any).
• For layouts defined in JSON, you can specify the base layout in the extends property of the root node.
• For layouts created in code using InputControlLayout.Builder, you can specify a base layout using InputControlLayout.Builder.Extend().
