Sorting a QVector

[marcel]

Actually qSwap doesn't use memcpy directly (4.3 beta):

Weird enough. It must have remained a beta .
I can't really find this implementation anywhere in 4.3.0 ( not beta ).

I even made small test and stepped in qSwap. The one I posted above is used for all types.

EDIT:
I think those casts only switch the base addresses of the variables without actually swapping any memory or calling =() operators.

Hi all

I am trying to sort a QList. I am using a custom type with overloaded < operator but then to check out the source of error, I changed the list to a interger one.

My code now is just this:

QList<int> list;
list << 10 << 5 << 4;
qsort(list.begin(), list.end());

I am getting the following error.

Cannot convert QList<int>::iterator to void* argument for '1' to 'void qsort(void* ,size_t, size_t, int (*) (const void*, const void*))'

Can anyone suggest what would be the possible error?

It is qSort, with capital "S".

Or, if not, try:

qSort(list.begin(), list.end(), qLess<int>());

qSort(list.begin(), list.end(), qLess<int>());

You can also simply call "qSort(list)" if you want to sort the whole list.
