Member Function Documentation

computeArrowRects()

virtual void IlvSpinBoxLFHandler::computeArrowRects ( const IlvSpinBox *  spin, IlvRect &  decrArrow, IlvRect &  incrArrow, IlvRect &  internal, const IlvTransformer *  t  ) const

pure virtual

Is called to compute the bounding boxes of spin box items.

Parameters

spin	The spin box.
decrArrow	The returned bounding box of the decrement arrow.
incrArrow	The returned bounding box of the increment arrow.
internal	The internal bounding box where to draw the objects of the spin box.
t	The transformer.

Implemented in IlvSpinBoxWLFHandler, IlvSpinBoxVXLFHandler, IlvSpinBoxW95LFHandler, and IlvSpinBoxMLFHandler.
