All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, StyleEditorEntity, View, ViewListener

Direct Known Subclasses:

ViewGridIndexed

public class ViewGrid
extends CompositeView<ChartPaintTags>

Layouts several sub-views in a grid. Using order in which views are added to the grid, they are placed one by one to toFill the first row of grid from left to right, then the second row and so on. To control where each view is inserted ViewGridIndexed subclass can be used.
