Kambiz,I have some new questions,please help me.
I create some new Objects, want to save to file,but when I use SaveToFile mothed,find it can't to save .I viewed the source of SimpleGraph.pas,which is save the List of TObject.if i want to save my Objects to file,i should to modefy the source of SimpleGraph.pas,shouldn't I?
I really don't want to modefy the source of SimpleGraph.pas,because if i do it , the Component will lost commonality,do you have a good idea?
Thanks~~~
