virtual void IlvScrollBarMLFHandler::computeBBox ( const IlvScrollBar *  sb, IlvRect &  arrow1, IlvRect &  internal, IlvRect &  arrow2, IlvRect &  thumb, const IlvTransformer *  t  ) const

virtual

Is called to compute the bounding boxes of the scroll bar parts.

Parameters

sb	The scroll bar.
arrow1	The rectangle of the left/top arrow.
internal	The rectangle of the internal part.
arrow2	The rectangle of the right/bottom arrow.
thumb	The rectangle of the thumb.
t	The transformer.

Implements IlvScrollBarLFHandler.

virtual void IlvScrollBarMLFHandler::drawArrow ( const IlvScrollBar *  sb, IlvPosition  position, IlvPort *  dst, const IlvRect &  arrow, const IlvRegion *  clip  ) const

virtual

Is called to draw the arrows of a scroll bar.

Parameters

sb	The scroll bar.
position	The orientation of the arrow.
dst	The destination port.
arrow	The bounding rectangle of the arrow.
clip	The clipping region.

Implements IlvScrollBarLFHandler.

virtual

Is called to draw the internal part of a scroll bar.

Parameters

sb	The scroll bar.
dst	The destination port.
internal	The bounding rectangle of the internal part.
thumb	The bounding rectangle of the thumb. This rectangle must be included into internal.
clip	The clipping region.

Implements IlvScrollBarLFHandler.

virtual IlBoolean IlvScrollBarMLFHandler::isValidPosition ( const IlvScrollBar *  sb, const IlvPoint &  point, const IlvTransformer *  t  ) const

virtual
