javax.swing.JList
ca.bc.webarts.widgets.dnd.DnDList
An extension of JList
that supports drag and drop
to rearrange its contents and to move objects in and out of the list.
The objects in the list will be passed either as a String by calling
the object's toString() object, or if your drag and drop target
accepts the TransferableObject.DATA_FLAVOR
data flavor then
the actual object will be passed.
I'm releasing this code into the Public Domain. Enjoy.
