So my code would look like this:

vector<string> names;
size_t i;

combo_box::combo_box: (QWidget *parent) : QDialog(parent)
{
ui.setupUi(this);

for (i = 0; i 1= names.size(); ++i)
{
ui.name_combo->addItem(names[i]);
}

}

Will STL strings work or is there a conversion to QtString I will need to make?
