Class API¶

class Arrow(XYObjectMixin, LineOnlyMixin, DrawObject)¶

Draws an arrow

It will draw an arrow , starting at the point XY points at an angle defined by Direction.

Methods¶

__init__(self, XY, Length, Direction, LineColor='Black', LineStyle='Solid', LineWidth=2, ArrowHeadSize=8, ArrowHeadAngle=30, InForeground=False)¶
