Description copied from class: AbstractCell

Handle a browser event that took place within the cell. The default implementation returns null.

If you override this method to add support for events, remember to pass the event types that the cell expects into the constructor.

Specified by:: onBrowserEvent in interface Cell<java.lang.String>
Overrides:: onBrowserEvent in class AbstractInputCell<java.lang.String,java.lang.String>

Parameters:: parent - the parent Element; value - the value associated with the cell; key - the unique key associated with the row object; event - the native browser event; valueUpdater - a ValueUpdater, or null if not specified

render

public void render(java.lang.String value,
                   java.lang.Object key,
                   SafeHtmlBuilder sb)

Description copied from interface: Cell

Render a cell as HTML into a SafeHtmlBuilder, suitable for passing to Element.setInnerHTML(java.lang.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.

Specified by:: render in interface Cell<java.lang.String>
Specified by:: render in class AbstractCell<java.lang.String>

Parameters:: value - the cell value to be rendered; key - the unique key associated with the row object; sb - the SafeHtmlBuilder to be written to
