Member Enumeration Documentation

◆ PathElementType


For this type, x1 and y1 will be set to indicate the first point in the subpath.


For this type, x1 and y1 indicate the end point of the line.


For this type, x1, y1, x2, y2 indicate the control point and endpoint of a quadratic curve.


For this type, x1, y1, x2, y2, x3, y3 indicate the two control points and the endpoint of a cubic curve.


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 ( )

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.
