That's it exactly... the extended JButton contains a myObject and using dnd, I'm transferring it (myObject) from one button to another. myObject is a JavaBean, but not a component in the sense that it inherits from a java Component. Now the extended JButton is obviously a C/component and they need to be capable of being repositioned on the JPanel by the user. Like I said earlier, this solution seems kind of a kludge, but the only way I can figure to pull off the dual nature of dnd with a mousemotionlistener is to require the user to "switch modes"... i.e. require them to select a item from a toolbar which then activates or reinstates dnd listeners, and a second tool which switches the buttons back to using the motionlisteners. I'm a bit concerned about the overhead of this as there may be quite a few buttons on the JPanel - maybe a hundred or more but likely less than 500. Any better idea? -J "John P.
