Hi, Slavcho

I want to use the value of the TextBox or the arrow keys to control the movement of the ShapeNode in the diagram, so I need to define an origin coordinate (0,0) position, so that the midpoint of the ShapeNode is relative to the origin (0,0) position movement.

1. I want to set the position of the origin (0, 0) to the upper left corner of the diagram. How do I achieve this?

2. If the origin (0, 0) is set to the center point of another ShapeNode, it means that a ShapeNode moves with the center point of another ShapeNode as the origin. How do I achieve this?

Best regards.
