Member Function Documentation

begin()

void QDashStroker::begin ( void *  customData )

inlineoverridevirtual

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.
