Yes, this is exactly what I was thinking... The benefits are, it's impossible to drag the content off the screen, as you are ultimately "remote controlling the scrollbars" to handle the movement of the content. It just "looks" like you are using the mouse to pan things around.
So what you are both saying then, is I should just listen for the Mouse Movements, and have it update the Horizontal & Vertical Scrollbars? I don't have much experience, messing around with Scrollbars and their associated values. Is it as simple as listening for the changes in X,Y - and if there are changes in the "X" axis, then trigger a function to change the Horizontal Scroll? And then in the "Y", change the Vertical? This topic is very interesting to me, and I'd love to hear more on how to accomplish something like this.

If it's really a matter of scrolling a container that has scrollbars by dragging the contents, I would use a mouselistener (as mike suggested) that would update the verticalScrollPosition and horizontalScrollPosition of the parent container. You wouldn't actually be "moving" the inner stuff at all. You would sort of be faking the dragging. Why do it like this? 1. dragging too far one way or the other wouldn't drag the inner components out of the viewable area, 2. if you actually wanted to use the scrollbars as well then they would still work (and they would update correctly as you're dragging) Just my two cents.
