setLabelledWidget

public void setLabelledWidget(com.google.gwt.user.client.ui.Widget labelledWidget)

This method sets the Widget labelled by this LabelWidget. You should always associate the input widget with a LabelWidget via this method for advanced usability and Accessibility.
ATTENTION:
This method creates a bidirectional connection of this LabelWidget and the given labelledWidget via String attributes pointing to each others IDs. If an ID is changed afterwards this connection will break. If you are using this classes directly and not via UiWidgets you have to take care of this and re-invoke this method in case an ID changes.

Parameters:

labelledWidget - is the Widget labelled by this LabelWidget.
