◆ begin()

void QStrokerOps::begin ( void * customData )

virtual

Prepares the stroker.

Call this function once before starting a stroke by calling moveTo, lineTo or cubicTo.

The customData is passed back through that callback functions and can be used by the user to for instance maintain state information.

Reimplemented in QDashStroker.

Convenience function for stroking a polygon of the pointCount first points in points.

If implicit_close is set to true a line is implicitly drawn between the first and last point in the polygon. Typically true for polygons and false for polylines.
