I am trying to figure out if there is a way to associate one object to another in Tkinter. I would like to add ovals onto my Tkinter canvas but only to a pre-existing line object, i.e., I do not want the user to be able to add ovals anywhere on a canvas except for on the line object. Is there another way to do this other than restricting the addition of the oval to the x0, x1, and y0, y1 min/max of the pre-existing line object? Thanks in advance!
