Drag and Drop - drag from hook

Administrator

Is there a hook sent to the containing morph when one of its submorphs gets dragged out? I don't see one.

Thanks.
Sean

Cheers,
Sean

You can achieve the effect with the message #justGrabbedFrom: sent to
the grabbed morph

Thanks Hilaire. I saw that one, but I'm wanting to notify the containing morph (i.e. former owner)

Cheers,

long time ago I did a simple drag and drop example to understand how it works.

Ok my example was different. I wanted to know how I can control dropping.

Yes you have to use dispatching. I did no see message sent to the owner
morph by the system.

You mean call a custom method from justGrabbedFrom:? The problem is that the grabbed morph is not a part of my project, and I want the behavior for *any* morph grabbed out of this container.

Yes, I will add a hook and submit to inbox. What should it be called? It's a weird passive-voice situation... #justGrabbedFromMe: aMorph? #justLost:? Ugly, but I can't think of anything better.

#submorphJustGrabbed: aMorph?
