Drag&Drop with JPanels
Hi, I'm creating a component for a process flow charting system, and have come to the point where I need to implement D&D between components. I have a panel containing expanding lists, where each list item represents a process definition. What I need to do is the following. Altogether, I'm going to have 3 controls derived from JPanel that will need to support D&D.
Process Definition Panel (Source)
These will be the cell components within the aforementioned list; each one will encapsulate a process definition, which should be draggable into the chart to either create or replace process instances.
Process Flow Chart Panel (Target)
This will contain the process flow chart. Dragging a process definition into this control should create a new process instance in the form of a process instance panel.
Process Instance Panel (Target)
This represents a process instance within the chart (i.e. they are the "boxes" within the flow chart). By dragging a process definition onto one of these, the existing process instance should be replaced by a new one spawned from the definition.
All I need is a nice simple explaination of how D&D works in Java using Swing. I've already started creating a helper class that creates DataFlavors and Transferables from objects, but I'm not sure where to go from there.
Thanks, Lee.
