Can i use qt designer or i should just use code?

Notes: I attemp to use QLabel and put --- and | but they don't stick.

My question is , Which widget can help me?

Answer 1

The box that you have circled in the image is a QGroupBox, and can be created using the QtDesigner. Other widgets can then be inserted into like any other widget that supports layouts.
