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.

There is no option for that AFAIK. To implement it, you'll want to start here: https://github.com/gnuradio/gnuradio/blob/main/grc/gui/DrawingArea.py#L213 The grid size is defined in https://github.com/gnuradio/gnuradio/blob/main/grc/gui/Constants.py#L50 Best add a color in?https://github.com/gnuradio/gnuradio/blob/main/grc/gui/canvas/colors.py To make it optional grep for some action like TOGGLE_SNAP_TO_GRID and add your own in the same manner.?
