[Netron-graphlib] RE: Black-box shapes / Grouping

[Illumineo <Net...@ho...>]

Helge, thank you for your suggestions! I am curious about the course you
give...about what precisely; pc-assited proces-engineering, automata,
modelling dynamical systems..? It reminds of "Stella", the modelling
software I tried out many years ago, from High Performance Systems. Still
have a book here around "Dynamic modelling of environmental systems". Very
interesting. If you need someone to lecture about it, I wouldn't mind taking
a sabatical year :-)

The moving connectors. Yes, it's something I spoke in my blog about around
the summer this year. Not too difficult, just a lot of if-the-else to check
in which quadrant the connection is swimming in. It's what you see in the
Visio when using dynamic connections; fun to see how the connection jumps to
keep things nice and neat.

Z-order. Easy to do, as you say. Instead of a straighforward loop in the
Invalidate, one needs an additional re-ordering on the basis of a shape's
z-property. With a performance penalty however. Actually, I'm quite happy to
see how the Netron control still performs well although so much if being
calculated under the hood. In this context I still have to write a lot in
the architecture paper about how to tweak the lib for performance in
function of different situations. I think half of the code can be dropped if
one wants only to *show* diagrams, not manipualte them.  At this moment the
lib is for everybody and nobody in particular, just to maximize the
audience. 


I have uploaded the code. Time for me to sit back a while. Usually I start
playing with Photoshop, Cinema 4D and Mathemica to compensate for too much
rational effort ;-) 


Have a nice Sunday!
