Member Function Documentation

virtual const UStyle& ULabel::getStyle (  UContext *   )  const [virtual]

returns the contextual UStyle of this object. This virtual function calls the makeStyle() static function that was redefined for this specific class see also: UStyle and makeStyle() functions Reimplemented from UBox.

const UStyle & ULabel::makeStyle (   )  [static]

creates the Style of this object. This static function is redefined by each class that derives from UGroup. It is called by the virtual function UGroup::getStyle() note that certain classes have several makeStyle() functions (in which case they also have a specific getStyle() function) see also: UStyle and UGroup::getStyle() Reimplemented from UBox.
