API Referenceclass

class UIShowView

A view object that renders and controls a referenced view.

class UIShowView extends View;

Description

A UIShowView object renders its contained view object, when the when property is equal to true, and the unless property is equal to false.

The contained view object can be created from a view builder, or referenced using a binding. In the latter case, the view object is not directly attached to the UIShowView object, but must be attached to another object, such as an activity.
