How to create an "Calendar Choosing"

Hi all,
I want to modify details of an file, include “Date-time created”. How I show to user a calendar for user choosing?
Thank so much

If you haven’t made the logic part behind the calendar then you can look for any calendar in c++ you find so you can get a grasp, but basically it’s just a custom class. Reading both of your posts I guess you struggle with the GUI part, so at what stage are you stuck with?

Thank @johngalt91 for your reply, actually, I struggled with UI part like you think :frowning:
