Hi rooters!

I am try to nodify the program example of TOrdCollection...
But I want to apply this to an object having 2 values x and y.
The sorted list will be :
x1 y1
x1 y2
x2 y3
x3 y4
...

with x1<x2<x3 and y1<y2 (y3 and y4 may be greater or smaller than y1
and y2).

In the example the Compare member function for the objet class
containnig only 1 value is:

Int_t Compare(TObject *obj) {
if (fX == ((Value*)obj)->fX)
return 0;
else if (fX < ((Value*)obj)->fX)
return -1;
else
return 1;
}
};

How can I do in my case to define such a Compare member fuction?

Thank you
