public class Grid extends HTMLTable
Widget
within its cells. It must be
resized explicitly to the desired number of rows and columns.
Grid widget consists of <g:row> elements. Each <g:row> element
can contain one or more <g:cell> or <g:customCell> elements.
Using <g:cell> attribute it is possible to place pure HTML content.
<g:customCell> is used as a container for
Widget
type objects. (Note that the
tags of the row, cell and customCell elements are not capitalized. This
is meant to signal that the item is not a runtime object, and so cannot
have a ui:field
attribute.)
For example:
<g:Grid> <g:row styleName="optionalHeaderStyle"> <g:customCell styleName="optionalFooCellStyle"> <g:Label>foo</g:Label> </g:customCell> <g:customCell styleName="optionalBarCellStyle"> <g:Label>bar</g:Label> </g:customCell> </g:row> <g:row> <g:cell> <div>foo</div> </g:cell> <g:cell> <div>bar</div> </g:cell> </g:row> </g:Grid>
