Hello,

I am trying to rotate a vector curve about a certain point. I have an anchor point that will only move about the y and x axes. The arrow point (the top of the vector) moves along with the anchor point (via the change in x and change in y of the anchor point). The arrow point need only to rotate around the anchor point. I need to vector length to stay the same while the arrow point rotates.

I have installed the canvas picker and subclassed it myself. I am able to rotate the arrow point, but, the user is allowed to resize the actual length of the vector curve. I do not want to be able to resize that vector length.

How would I go about rotating that arrow about the anchor point?
