I didn't know what you were trying to do, so I answered random unrelated

Well, you can just override #setExtentFromHalo: if you want to change how the 
yellow resize halo handle works. Another example from Connectors:

-------
setExtentFromHalo: anExtent
	"The user has dragged the grow box such that the receiver's extent would be 
anExtent.
	Ignore the user's wishes completely."
-------

Likewise for brown-handle moving, you could override 
#setConstrainedPosition:hangOut:

Or you could override the methods that construct the halo handles themselves 
(#addGrowHandle:, #addScaleHandle: #addDragHandle:, etc.)
