Doesn't change the widget's direction or horizontal alignment if directionEstimator is null. Otherwise, the widget's direction is set using
the estimator, and its alignment may therefore change as described in
setText(String, Direction).

This will have the following effect on the horizontal alignment:
dir
parameter). If that is DEFAULT, the locale direction is used.
setText in interface HasDirectionalTexttext - the widget's new textdir - the text's direction. Note: Direction.DEFAULT means
direction should be inherited from the widget's parent element.
