[Extgraph-developer] TGraphNode.Parent

[Marco W. <in...@ca...>]

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.
