QTreeView sorting

Hi All.
I trying to use:

Code:

---

struct FLess : public std::binary_function<HASH, HASH, bool>
{
  int Col;
  static void setCol( int C );
 
  inline bool operator()( const HASH &rec1, const HASH &rec2 )
  {
    return ( rec1.hash.value( Col ) < rec2.hash.value( Col ) );
  }
};

---

In programm:

Code:

---

FLess::setCol( 5 );
 
if (order == Qt::AscendingOrder)
    std::sort( Records[i].begin(), Records[i].end(), FLess() );

---

How make sort by Col?
Thanks.

What exactly do you want to achieve, and why do you want to achieve that (that might help in helping you).

If I put number, for example 5 all works normally

Code:

---

return ( rec1.hash.value( 5 ) < rec2.hash.value( 5 ) );

---

I need to read out from a variable

Code:

---

return ( rec1.hash.value( SomeVariable ) < rec2.hash.value( SomeVariable ) );
