TsimpleGraph. Idea: Formated settings?

[elias]

Kinds of settings:
Procedure setLinkable:string
Procedure setresizable:string
Procedure setselectable:string
Procedure setcontinable:string
Procedure setIdontknow:string

Formatting Settings:
Node1.linkable:='Type #1'
Node2.linkable:='Type #1'
Node3.linkable:='Type #2'
Node4.linkable:='Type #2'
Node1.Resizable:='Never'
Node2.Resizable:='If unlinked'
Node3.Resizable:='If unlinked'
Node4.Resizable:=''
Node1.Continable:='Rectangles only"
Link1.Idontknow:='blahblahblah'

Conditions table: how client likes; In case of no conditions, defaults. examples:
-nodes only links if formatted equal: Node1 only with node2,Node3 only with node4
-nodes formatted resizable "never" doesn't resize
-nodes formatted Resizable "If unlinked" resize if unlinked
-Nodes formatted continable "Rectangles only" just contains rectangles
and etc.etc.etc. whatever the programmer likes

Opinions?

But, you could do all this if derived your own objects and added the necessary stuuf to them, couldn't you?

I guess it is possible but in any cases; e.g.: To make a nodeA linkable with node B but not with node C I have to modify "function TSimpleGraph.IsValidLink" inside TSimpleGraph class. I guess there are more examples.
"function TSimpleGraph.IsValidLink" is useful to put such restrictions; but it's not his real function.
What I find interesting is having an easy way to put whatever restrictions and conditions when editing even being they labyrinthic.
However, Idea was just a idea. It's possible it's not the best way.

(The terms used in this post refers to v1.67; i have not yet changed to the new release in my app)(I'll do it sure when the time allow me).
