Hi, all,
 
Now i can draw curves by clicking several points on the canvas following some algothem.
 
If i don't like the curve, i intend to delete by remove some of the points i have choosed and  try new points again.
 
Does anybody know how i should do this? do i need to creat a new canvas group for each point so that i would use g_object_destroy (group) to remove the portion of curve?
is it the only way??
 
It's kind of urgent
Thanks in advance.
