Dear Mr.Thompson,

Thank you very much for the help. it has been very useful.

Regarding the doubt you expressed about he draggable buttons, the
project i'm doing is to develop a graph creation tool. To represent
the nodes in the graph i'm using button instances. These are joined
with lines to create the graph. The nodes needs to be dragged around
in the graph creation area so that the user can change the graph.

Hope this gives you an idea of what this gives to the user.

Thanks again

Chanchal

Is there a reason you're not using labels instead of buttons? Buttons 
have a concept of triggered, which could interfere with your concept of 
dragging.  You can attach a mouse listener to a label and simulate the 
dragging yourself (I've done this for graph visualizations myself).  If 
there is a *reason* you need a button instead of a label, you might find 
yourself recreating the button functionality in a way that is compatible 
with your dragging.  I shouldn't want to be the one that maintains 
/that/ code.

That is a good description.

Yep.  That para. about sums up my own thoughts
on the matter, given the use.

Why not use labels for the draggable nodes?
