I am writing a tic-tac-toe game in plt-scheme as my AI course project. The idea for gui is a grid with 9 boxes, each with a canvas, using panes ... When the user click on a canvas, 'X' or 'O' will be drawn accordingly ...

The question is how can I catch mouse click event on canvas? I found out I need to use on-event, but still don't know how? Any clues?
