QgsRubberBandPreviewItem::QgsRubberBandPreviewItem ( QgsRubberBand * rubberBand )

protected

Constructor for a QgsRubberBandPreviewItem, attached to the specified rubberBand.

Definition at line 857 of file qgsrubberband.cpp.

QRectF QgsRubberBandPreviewItem::boundingRect ( ) const

virtual

Returns the bounding rect required for drawing the preview item.

If non-empty, these bounds will be combined with the parent rubber band's bounds in order to avoid graphical artifacts when the band is moved.

The default implementation returns an empty rect.
