Hi
I would like to be able to place my cursor over a picture in a draw
widget, tap the left mouse button and a square of n x n (defined in
software) white pixels drawn on the picture and all x and y coordinate
values sent to an array. I have selected the BUTTONS_EVENTS keyword in
the draw widget and used the WSet command to make it the current
graphic window but what else?? How do I use the event structure??

BTW thanks to all who have responded to my embarrasingly simple to
answer questions before.

Cheers

David
