Topic: GRREAD Question

[Lee Mac]

I was just wondering, what is the difference between using:

Code: [Select]

(grread t)

And

Code: [Select]

(grread nil 1)

Both seem to be documented as returning the drag coordinates - so which should I use when creating a function that tracks mouse movements?

Thanks as always,

Lee

I use it that way :  (grread t 4 4))  , that allows me to use any keyboard key in my routine (any letter, enter, space-bar..)

You might want to use this useful code below for your own testing/learning purpose

(while (setq input (grread t 4 4))
      (princ (strcat "\n" (vl-princ-to-string input)))
      )

cheers
