I'm not sure NSMatrix is the right choice here. Maybe you should 
create your own custom view. You can then handle all mouse events any 
way you like. It shouldn't be too much work, since you can keep your 
cells to do the drawing.

Set a flag in the view on -mouseDown: and check it from the cell's 
drawing code.
