Public Methods

public void onBrowserEvent (Cell.Context context, Element parent, C value, NativeEvent event, ValueUpdater<C> valueUpdater)

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.

Parameters
context the Context of the cell
parent the parent Element
value the value associated with the cell
event the native browser event
valueUpdater a ValueUpdater, or null if not specified

public void render (Cell.Context context, C value, SafeHtmlBuilder sb)

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

Protected Methods

protected void onEnterKeyDown (Cell.Context context, Element parent, C value, NativeEvent event, ValueUpdater<C> valueUpdater)

Called when the user triggers a keydown event with the ENTER key while focused on the cell. If your cell interacts with the user, you should override this method to provide a consistent user experience. Your widget must consume keydown events for this method to be called.

Parameters
context the Context of the cell
parent the parent Element
value the value associated with the cell
event the native browser event
valueUpdater a ValueUpdater, or null if not specified
