Hello Michael,
Thanks for your help again.
I still use these listeners. Do you mean that I have to check that the canvas point the user clicked, is simultaneously covered by the edge of a roi?
I seems a little bit cumbersome to me. Is there no easier way?
Is there no possibility that ImageJ gives me a callback when the user hit the edge of a Roi, with the mouse button, so he resizes the Roi, while dragging it?
Kind regards,
Michael
