Does anyone know how to simulate drag and drop? I managed to pick up a morph via HandMorph attachMorph:, but I can't get the cursor to move (tried position: and a few others).
Thanks.

How detailed do you need the simulation to be? In the end, dropping results in
targetMorph addMorph: droppedMorph

Thanks. I tried it and it didn't work because what I'm doing is writing an acceptance test, and I need the drag & drop events to fire. When I do that only, it just adds the "dropped morph" as a sub-morph to the target.
Also, I'm highly curious about how to programmatically interact with the HandMorph in general. I looked at HandMorphForReplay a little bit, but it seems to use recording of positions (which would be too brittle for a high-level test).

How about this?
droppedMorph formerPosition: 50@50. "to test rejecting" ActiveHand position: targetMorph center; attachMorph: droppedMorph; dropMorphs

Your best bet would be to subclass HandMorph similar to HandMorphForReplay or RemoteHandMorph.

Right on the money! I was doing the ActiveHand>>position: by itself in a workspace, and the cursor does not get updated, so I thought it wasn't working (need a fresh pair of eyes!). When I did the drop immediately after, everything worked great. Thanks again :)

Great idea - kind of like living documentation?!

I did a little more investigating and found a way to get the mouse handlers to work: mvevt := MouseMoveEvent new setType: #mouseMove startPoint: ActiveHand position endPoint: 100@100 trail: nil buttons: 0 hand: ActiveHand stamp: TimeStamp current. ActiveHand handleEvent: mvevt.
evt := MouseButtonEvent new setType: #mouseDown position: 50@50 which: MouseEvent redButton buttons: MouseEvent redButton hand: ActiveHand stamp: TimeStamp current. ActiveHand handleEvent: evt.
The mouse move is necessary or the grabbed morph flies to wherever the hand is, but even with this, if you touch the mouse after it's grabbed, it flies there anyway.
Hi Sean,
You don't have to use the ACTIVE hand. Any hand will do.
e.g.
artificialHand = HandMorphForReplay new .
You will have to play and look at the classes. I haven't ever tried this. So I don't know if this particular solution will work. It should be close.
Worse comes to worse you could base an ArtificialHand class on HandMorphForReplay and make something that worked to your requirements.
Happy hunting.
Yours in curiosity and service, --Jerome Peace
