[oruccim]

Hi All,
i am trying to sort my a QList (static QList<MyClass> list; ) but nothing change on the
list .
here is the code

bool caseInsensitiveLessThan(const Myclass s1, const Myclass s2)
{
return (s1.id < s2.id);
}

qSort(list.begin(),list.end(),caseInsensitiveLessT han);

there is no error on my code. After adding this statements, my list is still same, nothing is changed.
is there anyone have an idea why the list is still same,
thank you...
