Has anybody used the #grabTransform message that is sent by HandMorph as part of picking up a Morph? Every use I can find of it seems to set it to an Identity transform and trying to use it for make my dragged morph appear half-size is not working in a very understandable manner.
HandMorph>grabMorph:from: is the major player here; it asks the formerOwner for the grabTransform (without specifying for which grabbed morph, which seems odd) and uses that along withe formerOwner’s transform to do things to the grabbed morph. If I make my owner-morph implement grabTransform to return an identity transform, the grabbing works as normal. If I provide atransform that does any scaling (which is what I want to use) then a) the positions and offsets get all screwy b) dropping doesn’t work the same - you have to drop the morph and then click-release again to get it to actually drop. That part really confuses me right now.
I doubt this code was stuck in for the fun of it so I feel sure somebody must have had a use for it in the past. Does anyone remember anything about it?
Oh joy; power cut. Hopefully the UPS will last long enough to get this sent.
