Hi Marco,
=20
I've updated your privileges on SF, you should now be able to add / =
change tasks.
=20
As for your ideas, I especially like the layers and do not have a =
problem with any of the other suggestions.=20
Please do keep us updated, we'd love to see some code once you've got =
things up and running.

If you need any help on any of the things, please contact us, maybe we =

Onderwerp: [Extgraph-developer] TGraphNode.Parent


Hi guys,

Just some thoughts (and work in progress) on the GraphObjects...

Parent
I'm building some code into the TGraphNode to support some kind of =
Parent much like the TControl does in the VCL. This is for the obvious =
reason to support a grouping like behaviour. Parents would paint =
themselves first and in addition it would paint it's children. Similarly =
if moved, it would move the children. In several vector drawing tools it =
would be considered some kind of grouping where the parent is simply the =
first object in the list.

Layer
I'm also thinking about layers similar to this. Every GraphObject would =
be defaulted to the single layer in the TSimpleGraph. The Graph could =
have several layers and including a visible property and an ActiveLayer =
index. It would certainly add value to the current ZOrder and individual =
visible states.

Lock
Simple to realize is the lock propert on individual Nodes instead of the =
entire Graph. This could be finetuned into the layering and parenting...

So far my thoughts. As work progresses I'll keep you posted. In the =
meanwhile I've discovered that I cannot add Tasks and stuff in the =
SourceForge site. Is there something you can do to arrange this?

Marco.
