How to get windows folder display order by C + + - windows

Question

I need to get the pictures in the windows folder and sort them according to the order in which they are displayed. Now there is a method to traverse the entire folder display items through the handle by getting the folder window handle. However, this method has a drawback: it can't get the order of the unopened folder, because there is no open file and no window handle.
Qt is used.
Please forgive my grammatical mistakes.
