Drag Drop image wells help

Hey Gang! am working on a project w/QC guts/Cocoa front end, and am trying to get a drag/droppable interface to drop Quicktimes on to feed the QC patch. Have been thru developer materials and even the Visualizer and can't get quite the hang of it. Does anyone have a working cocoa front end Xcode project(with drag/drop quicktimes working) that I can look at the code-guts to see what I am doing wrong?

Just trying to feed movie loader patches with file paths

thanks! jd
