onBrowserEvent

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

onBrowserEvent in class AbstractCell<String>

Parameters:

context - the Cell.Context of the cell

parent - the parent Element

 Element parent,
 String value,
 NativeEvent event,
 ValueUpdater<String> valueUpdater)

Description copied from class: AbstractCell
