Change cursor when hovering over grip

When the cursor hovers over a grip in a normal component, the cursor changes to include a little bezier curve with an arrow at the end to show that the cursor is near a grip can can “pull” a wire out from a grip nearby.

I’m trying to find for the function/property which implements this functionality. I overrode CreateAttributes() in my component.

I don’t think I should handle the RespondToMouseMove event as they are triggered only when the cursor is within the Bounds of the component/attribute, which is usually just the main body (the capsule), whereas the input and output grips lie outside of those bounds.

If anyone can shed a bit of light on this that’d be great.
