Draggable Controller

After reading all the comments added on the Drag n’ Drop Tree component made some time ago I spent some time to make a small component which is capable to manage drag and drop between almost all the Macromedia builtins component (such as List, DrataGrid, Tree…).
It requires Flash 8 to work because I’m using BitmapData for clone the dragged item (wow, this is incredible easy to do now 🙂 )
You can see a demo here: DraggableController.html
This is the code used in the .fla, in order to manage the component events:

The .zip with all the file is available here, if anyone want to test and improve it.
