No, they actually have different sizes.
My project is to connect one box to another using an arrow. Then I found out that this boxes could be jButtons, so I could drag and drop them easily
I thought that maybe I could do it by linking a small jButton to the "box", so whe the user clicks the small jButton, and drags the mouse to another small jButton, then, an arrow is drawn connecting the two boxes...
By the way, there is something very similar to what I want to do in this page: http://jdsp.asu.edu/jdsp.html
Any suggestions? thanks a lot
