UIElement
Along with the ViewElement class, the UIElement class is one of the abstract base classes of all UI elements. All UI elements that can be used within Web Dynpro have three generic properties that the UIElement object passes on to the UI element subclasses. This abstract UI element also allows you to access the LayoutData object that can be used to describe the alignment of one UI element with another UI element.
The term UI element stands for a stand-alone user interface element that can be stored in a general container. Whereas view element also stands for subelements of composite UI elements. For instance, TabStrip is a UI element. The subelement Tab is a view element because it cannot be used independently. It is only used to build up a TabStrip UI element. The subelement Tab is therefore not a UI element.
The UIElement is an abstract UI element.
