Constructor & Destructor Documentation

◆ QDashStroker()

QDashStroker::QDashStroker ( QStroker * stroker)

Definition at line 989 of file qstroker.cpp.

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.

Reimplemented from QStrokerOps.

Definition at line 249 of file qstroker_p.h.

◆ end()

void QDashStroker::end ( )
inlineoverridevirtual

Finishes the stroke.

Call this function once when an entire primitive has been stroked.

Reimplemented from QStrokerOps.
