Member Enumeration Documentation

◆ PathElementType

enum Path::Iterator::PathElementType

Enumerator
startNewSubPath	For this type, x1 and y1 will be set to indicate the first point in the subpath.
lineTo	For this type, x1 and y1 indicate the end point of the line.
quadraticTo	For this type, x1, y1, x2, y2 indicate the control point and endpoint of a quadratic curve.
cubicTo	For this type, x1, y1, x2, y2, x3, y3 indicate the two control points and the endpoint of a cubic curve.
closePath	Indicates that the sub-path is being closed. None of the x or y values are valid in this case.

Member Function Documentation

◆ next()

bool Path::Iterator::next ( )

noexcept

Moves onto the next element in the path.

If this returns false, there are no more elements. If it returns true, the elementType variable will be set to the type of the current element, and some of the x and y variables will be filled in with values.
