Hi Bob,


I think I see now what I missed out in my explanation. Ordinary morph drag and drop should not be affected by my change at all.

Actually you can still drag and drop morphs like before (even openInHand and dropping it afterwards).


What I intented to change was the drop behavior for the mechanism for opening a morph for an object dropped in the world (basically PasteUpMorph>>transferMorphConverter:).

For example, my method checks whether the dropped object is a Model and if so tries to open it with ToolBuilder.?


The drag starts in PluggableTreeMorph>>#startDrag: to answer your initial question.


Bests

Patrick

The real question is how the morph got attached to the hand in the first place. People have been picking morphs up and dropping them for decades, so there is something new here. Do you have the code that put the bowl into the hand?

Well before the change, the morph would have opened anywhere in the world. Most of the time that was not close to the hand.


You are right though, that the new behavior look weird too... Maybe this is because it looks good for dragging menu items?

I guess one question is why the bowl was attached to the hand at the lower left corner of the bowl rather than the upper left. If it had been attached at the upper left, then it probably would have dropped right where expected.

This allows for more "intuitive" drag and drop behavior. When I drop something into the world and a morph is opened for it than the morph is displayed at the position where the element was dropped. For a simple example so the gif attached.
