Thank you. Succinct, and not parroted. ;-) So the way it should go
is something like: "user begins dragging custom view, custom view
'image' is created for use with drag operation, drag operation
receiver handles things like the 'plus' cursor and possibly moves
other custom views out of the way (a la iMovie), and accepts the
drop, the custom view is 'removed' from the sending superview then
added to the target/receiving superview."
Is that about right?
Yes.
Much thanks, that's helpful.
If so, does anybody have a clean example project that does just this?
I like clean examples that don't combine other 'tricks' into one - it
just makes it easier to grasp the subject you're trying to learn when
there's nothing else mixed in. ;-)
There are examples of simple drag and drop, but not with the level of
specialization and sophistication you're looking for. Another thing to
keep in mind is that it's not simple to do all of what you want to do.
If you're familiar and experienced enough with Cocoa, you could
probably throw something together fairly easily, but it might not be a
very general solution.
That's pretty much what I figured. I couldn't get enough information
out of the existing examples to clue me in to how to do this the iMovie
way. That answers my main question insofar as examples, but I still
think we could all benefit from more explanations/examples/tutorials on
this topic. The more explanations we have from multiple viewpoints, the
easier it is to understand.
There's no way around it. You are going to have to get your hands
dirty and figure out how all this stuff works, get good at it, and
design what you need yourself. It will probably a while.
Ah, well. The above 'steps' now make sense and I think I've got
enough to re-read everything with new eyes. It's not an alternate
explanation, but it's at least *some* newly-phrased information, which
is all I wanted.
Thanks again.
