Member Function Documentation

virtual bool DtMultiLineDrawer::draw ( QPainter &  paint, const DtSymbol *const  symbol  ) const

virtual

draws the specified symbol on a device.

The symbol must be of a DtLineSymbol type or nothing will be drawn.

Returns

true if successful, false otherwise.

Reimplemented from DtLineDrawer.

virtual QSize DtMultiLineDrawer::calcBBox ( const DtSymbol *const  symbol ) const

virtual

Calculate the drawn size of this symbol.

The symbol must be of a type this drawer can recognize.
