Widget
This method is called when a widget is attached to the browser's document.
To receive notification after a Widget has been added to the document,
override the Widget.onLoad()
method or use Widget.addAttachHandler(com.google.gwt.event.logical.shared.AttachEvent.Handler)
.
It is strongly recommended that you override Widget.onLoad()
or
Widget.doAttachChildren()
instead of this method to avoid inconsistencies
between logical and physical attachment states.
Subclasses that override this method must call
super.onAttach()
to ensure that the Widget has been attached
to its underlying Element.
