Point.length()[source]

Returns the vector length of this Point.

Point.norm()[source]

Returns a vector in the same direction with unit length.

Point.angle(a, units='degrees')[source]

Returns the angle in degrees from the vector a to self.

Parameters

  • a (Point, QPointF or QPoint) – The Point to return the angle with
