[Qt-interest] Initialize const Qt container class

Hello all,
I realize this may be just a C++ question, but I was wondering if maybe Qt
had some additions that helped here. I often have some const data
structures that I want to initialize with data and don't have a good
(readable) way to do it.
Here's what I'd like to do (with standard c types):
struct item
{
char string[20];
int list[10];
};
//the following is nice and readable, easy to modify, etc.
const struct item items[4] = {
{"string1",{1,2,3,5,6,0}},
{"string2",{4,0}},
{"string3",{2,5,0}},
{"",{0}}
};
This makes it very easy to read and change my data initialization. But I'd
like to do this with Qt classes (QString and QList<int>) instead. I don't
know of any clean way like this to initialize everything in that case and
I was wondering if anyone had any slick tricks to do this or something
like it (really it's the QList<int> that's the problem, the QString will
initialize easy). If not, how do people initialize their (const) data
structures like this? (Note, I know how to initialize data structures in
the standard way using <<, but was looking for something "cleaner"). I
don't mind if there's a non const way to do this, but that would be nice
since the data won't change. Thanks!
Josh
