Yes that should be coded correctly. I've got very similar code in a Qt4 project.

I was wondering: what's the scope of 'liststr' ?

If you destroy it after you leave that stack frame, but you pass a
reference/pointer to the list to some other component before you
return, then the other component would have an invalid QList
reference/pointer.

Hope that helps,
