Re: GRC: is it possible to show grid

[Prof. M.B. Patil]

Thank you. This will be helpful. I was trying to
see if Gtk allows grid drawing with a single command,
but I could not find that. In that case, I guess I
have to do two loops: one for horizontal lines
(using move_to/line_to) and one for vertical lines.
If there is a better way, please let me know.
