A sample of deriving from node class?

[lee]

Can someone provide an example of deriving from a node class? I'm interested in seeing how to create custom nodes. I want to create a node that implements a property sheet. I'm just not sure which method to override to implement inserting another control in the node's area.

Thank you,

In the SimpleGraph, all nides are derived from TGraphNode. Therefore, you can consider each of nodes as a sample.

Hello Kambiz,

I don't mean to be a pain to you, but I don't understand where I can add what I want to add. I would like to place another component within a derived node. Is this possible?

Thank you and very nice product, BTW

Yes, you can.

After deriving a new node/link class, you should register it to SimpleGraph by calling Register class method of TSimpleGraph. After that, the new class can be used within SimpleGraph.
