The User Interface Element Container 

Each container UI element can be assigned a layout that defines the alignment of the UI elements within the container UI element. The following are container UI elements: Group, Scroll Container, Transparent Container, and Tray. The different layouts are represented by the following layout objects:

·        Flow Layout

·        Grid Layout

·        Matrix Layout

·        Row Layout

By default, one flow layout is created for each container UI element. Additional information is available under Layout.

Furthermore, you can define layout data for each UI element, depending on the predefined layout. For example, the layout data affects the alignment of the UI elements within a grid cell in the grid layout and is represented by the corresponding layout data objects:

·        Flow Data

·        Grid Data

·        Matrix Data

·        Matrix Head Data

·        Row Data

·        Row Head Data
