Fault trees by using TSimpleGraph

[SP_Kyle]

Hey everybody!

I'm newbie in SimpleGraph but I already like working with this component. At present I trying to build a fault tree for my researches...and logical nodes I am drawing as a circle with text('and','or',etc) but I want that logical nodes looked like standart logical nodes like on the picture...

If anybody has an example making this type of node or anybody may direct me at correct direction...please help me

P.S. I wanted insert picture in node but it's create some problems...so

I don't think you can use SimpleGraph for your application. In SimpleGraph, intersection of links and nodes determines automatically and can be anywhere on the nodes. But for logical gates, the links must be connected only to the in/out pins of the gates.
