Thanks, I already got it working, which was in fact a very
satisfying experience. My previous failure was using a
"handlesMousedown" method, rather than "handlesMouseDown:evt"
method. An important distinction.

These apparently don't do anything. But, that's OK, because I can, as
Bert suggested, just send "evt hand #grabMorph: self".
Except, oops, that's NOT OK, because now mouseUp: apparently never
gets
sent to my Morph.
So, I still need help. Thank you both very much.
They "worked for me" - I was dragging a Morph around, and had readouts
for the start and end positions of the dragging. Try making a
completely
fresh subclass of Morph with only the methods I suggested. I used
Squeak
3.9.
If I was going to implement momentum, I'd take the current position on
mouseUp: and the position received by the very latest mouseStillDown:,
and work out which vector the puck should travel in from that. I
suppose
you'd also need the times of those two events as well to calculate the
velocity vector.
Michael.
