[GRASS-dev] sugestions for an interactive 2 points loop gathering

Hi,

I would like to build an interactive module that would just gather two points (a center and a peripheric distance) in a loop fashion and add that to a text file in X1,Y1,X2,Y2.

I am not familiar with the GUI programming as it is to date, but happy to learn the needed.

Cheers,

Yann

maybe a starting point for an interactive set of coordinates
  #%option G_OPT_M_COORDS

see an example e.g. addon r.basin
