Moving a graphic object in Java

trentreznor -  
Does anyone have an idea on how to move a graphical object (type: I actually don't know) with the mouse?
The goal is to represent multiple objects, each having a name, using the mouse (to represent a graph, actually) and to

arrange them with the mouse.
Drawing is not a problem (with Canvas), but then I don't see how to move it with this method and I don't see another way.
