Hello! I am using InterViews to develop some graphics programs, and have run into a problem. I am using the persistant-graphics, and when the user selects an area on the screen (Using Rubber Rectangles, etc) I would like to be able to tell which of the graphics selected are Circles, or Lines, etc. Is there a nice way of telling what kind of graphic a graphic subtype really is? Also, is there some way to possibly do this with the Reference class? I tried this, but have been running into problems so may not be doing it properly. Thank you -Eli echarne@nrtc.northrop.com echarne@orion.cf.uci.edu echarne@ics.uci.edu zebcharne@uci.BITNET
