Qt C++ How can I show a users basic informations in a new window after login?

[moslehuddin]

I am trying to create an application in Qt C++. In this application, user can signup and login. After login I want to show their basic information in profile tab.This is my login panel (cus_login_signup.ui)

I want to Load information in the text label.
This is after login (cprofile.ui)

This is my database:
My sqlite Database

How can I load their basic information from my database and show them immediately after login in profile tab?

The question is very general. So what exactly is the problem you cannot solve, and what have you coded so far?
