QPainterPath QPainterPathStroker::createStroke ( const QPainterPath path  )  const

Generates a new path that is a fillable area representing the outline of the given path.

The various design aspects of the outline are based on the stroker's properties: width(), capStyle(), joinStyle(), dashPattern(), curveThreshold() and miterLimit().

The generated path should only be used for outlining the given painter path. Otherwise it may cause unexpected behavior. Generated outlines also require the Qt::WindingFill rule which is set by default.
