| canGrabFocus | Return true if the element can be focused. |
| focusController | Return the focus controller for this element. |
| focusIndex | An integer used to sort focusables in the focus ring. A negative value means that the element can not be focused. |
| Blur | Tell the element to release the focus. |
| Focus | Attempt to give the focus to this element. |
| HandleEvent | Handle an event, most often by executing the callbacks associated with the event. |

| HasTrickleDownHandlers | Returns true if event handlers, for the event propagation TrickleDown phase, are attached to this object. |
| RegisterCallback | Adds an event handler to the instance. If the event handler has already been registered for the same phase (either TrickleDown or BubbleUp) then this method has no effect. |
