Class Overview
An AbstractCell used to render an image. The String value is the url
of the image.
If the images being displayed are static or available at compile time, using
ImageResourceCell will usually be more efficient.

ImageCell
()
Construct a new ImageCell.
Public Methods
Render a cell as HTML into a SafeHtmlBuilder, suitable for passing
to setInnerHTML(String) on a container element.
Note: If your cell contains natively focusable elements, such as buttons or
input elements, be sure to set the tabIndex to -1 so that they do not steal
focus away from the containing widget.
Parameters
| context
| the Context of the cell |
| value
| the cell value to be rendered |
| sb
| the SafeHtmlBuilder to be written to
