Class DisplayMagnetWheel

Whether the DisplayObject contains the given world coordinates point.

Draws this DisplayObject using the given CoordMap.

Returns true if this DisplayObject has changed, and sets the state to "unchanged".

Returns the set of MassObjects that this DisplayObject represents. Returns an empty list if this DisplayObject doesn't represent a MassObject.

Returns this DisplayObject's position in space, in simulation coordinates of the containing SimView.

Returns the set of SimObjects that this DisplayObject represents. Returns an empty list if this DisplayObject doesn't represent a SimObject.

Sets the z-index which specifies front-to-back ordering of objects; objects with a higher zIndex are drawn over (in front of) objects with a lower zIndex.

Whether this DisplayObject is currently dragable.

Sets whether this DisplayObject is currently dragable; has no effect on objects that are not dragable.

Sets this DisplayObject's position in simulation coordinates of the containing SimView. Each type of DisplayObject has a different policy regarding whether this will have an effect. Generally the policies are:

• If the DisplayObject does not represent a SimObject, then the position can be set. Examples are DisplayClock, EnergyBarGraph.

• If the SimObject's position is dependent on other objects, then the position cannot be set. Examples are DisplayConnector, DisplayRope, DisplaySpring.

• If the SimObject can be moved independently and isDragable is true, then the position of the SimObject is modified. Example: DisplayShape.

Sets the z-index which specifies front-to-back ordering of objects; objects with a higher zIndex are drawn over objects with a lower zIndex. Default is zero.

Inherit Doc

Returns a minimal string representation of this object, usually giving just identity information like the class name and name of the object.

For an object whose main purpose is to represent another Printable object, it is recommended to include the result of calling toStringShort on that other object. For example, calling toStringShort() on a DisplayShape might return something like this:

DisplayShape{polygon:Polygon{'chain3'}}
