Spring

A spring is a 2D drawing element that displays a simple icon for a spring at given coordinates of the parent drawing or plotting panel. The shape is drawn relative (see the Position property) to the given coordinates with the size specified in each direction. The element can also be applied a rotation and a scale factor for each coordinate.

Object wrapped

 

The object wrapped by this element is of the class org.opensourcephysics.displayejs.InteractiveSpring. The class has been designed to control all of its features through properties, so there is no need to use directly any of the object methods.
