I am writing a DTP program that has a set of drafting tools.  Since
it is built on top of Post, I use PostScript objects.  Once an object
is on the screen, I want to be able to select it, and have a set of
proportional gadgets show up for the object (the endpoints of a line,
or the control points of a bezier, etc.) to allow the user to manipulate
the object.

Proportional gadgets live in a container, and in this case,
I want the container to be the whole window, and for there to be possibly
many prop gadgets.  The problem is that Intuition seems to assume there
is one prop gadget per container, because if you click anywhere in
the container, the gadget moves toward the click by a single increment.
This makes no sense if there are a ton of gadgets in the same container.
(I refer to Libs & Devices p. 84)

My question is, can I use Proportional gadgets for what I want to do?
If so, how do I get around this container problem?  If not, how
should I solve this problem?  (I assumed this was a tailor made application
for prop gadgets!)  I see "hacking" up a stationary set of gadgets,
and using followmouse as a possibility, but a gross one.

Any ideas? thanks,
dylan
