I've got very good news for you: writing new objects (if you're not aiming
for an UML Class look-alike) is not that difficulty; StdProp objects contain
zero GTK and zero libXML code. "all" you have to do is to build a property
description list, hand that over to the StdProp core; then you (still ;-) )
need to write the actual drawing (and mouse handling) code, using dia's own
interfaces.
I suggest you take the source of one object relatively close to what you
want to do, play a bit of search-and-replace, then experiment with the
PropDescriptors on one hand, and the rendering on the other. Any object
should be a rather good example nowadays (if you see any gtk or libxml stuff
inside, run away. If you see UML Class, dd if=/dev/zero of=/dev/hda)
I wish you a lot of fun!
