Examples of nextapp.echo2.app.Grid

nextapp.echo2.app.Grid
A layout Component which renders its contents in a grid. Each component is contained within a "cell" of the grid. GridLayoutData layout data objects may used to cause cells to expand to fill multiple columns or rows.
Child LayoutData: Children of this component may provide layout information using the nextapp.echo2.app.layout.GridLayoutData layout data object. @see nextapp.echo2.app.layout.GridLayoutData
