Re: Non-standard Dia use: Visualisation

Hello all,

Overall: I have not yet decided: will I develop my app or not.

I mean a model of a completely different kind, which is on-the-fly 
transformed into Dia model and then displayed by Dia. Maybe it's more 
suitable to develop a completely different project, I don't know yet.

Yes. My future app (I have not completely decided will I develop it or 
not) is of completely different nature than Dia, only the display/render 
routines are similar. So it would be at another package, not included 
with Dia.

I'm uncertain yet.

I didn't completely build the architectural model. Too early to build it.

The question was about interacting of a would-be future codebase with 
Dia, OR breaking all relations except for heritage relation. It seems 
Dia team is OK with code interacting between packages.

Yes, my would-be project is an out-of-Dia-tree plugin that would-be 
using Dia API (or using the Dia codebase metaprogrammatically, 
transforming into something, hooking at some places).

No. Not this at all.
