Hi!
Two guys in our team have been at this for several hours now and we decided it was time to seek help…
We want to accomplish something like the finder sidebar on the mac, where stuff can be rearranged in the order the user wishes (from top to bottom). I’ve attached a zip-file to show how far we’ve gotten and to illustrate what we want to do. The DropController can be set as a document class.
Basically, the user has a list of sprites to drag from, and then drop these sprites on a limited number of targets. When a target is occupied, the sprite it holds and the ones above/benieth it will slide up or down to make room for the sprite being dragged. If you’re on a mac with Leopard installed, try dragging the items under “PLACES” in the sidebar up or down. That is exactly what I want to accomplish, only it turned out to be surprisingly difficult.
Anyone feel like taking a crack at it? Thanks
