Thanks Hilaire,
that works fine. I can add the listener when the actual dragging starts and
remove it
on mouseUp.
MDShapedoDrag: aMouseMoveEvent with: aMDShape
ActiveHand addEventListener: self.
aMouseMoveEvent hand startDrag: aMouseMoveEvent with: aMDShape.
Hi,
Here is an implementation example.
From a workspace, do:
| morphA morphB follower |
morphA := Morph new position: 10@10.
morphB := Morph new position: 100@100.
follower := FollowerLineMoprh from: morphA to: morphB.
morphA openInWorld.
morphB openInWorld.
follower openInWorld.
Frankly I

Frankly I don't like the idea to subscribe to the HandMorph, because at
each mouse move event, you have to check for the morph A and B if they
move. It is a waste of CPU cycles.
Ideally you will want receive event from morph A and B whenever they
changed. I

I'm trying to keep a line morph connected between two morphs
while moving one of them.
When I add the morph to the hand and start dragging the morph
no longer receives mouseMove:. I can think of several ways to get
position updates. Is there a best/easy way?

Hi,
I think you need to subscribe to the hand morph. It provides some
possibilities. Of course if you drag morphs only inside it's parent, you
can implement dragging by yourself without adding to hand. In this case
mouseMove can be received.
Cheers,
Alex
