      There is no big difference except one additional class in case of designer. If you are beginner life may be easy to create the UI using designer.

        Hi
        Performance wise there is no difference to speak of.
        What ever you draw in UI files is translated to c++ code and run
        inside the setupUI(). Its not read in at runtime or anything like that.
        The pointers to the generated widgets are stored in the UI struct and
        with direct code they would just be directly in the .h instead.

        When code is running, the price for UI->widget->func extra indirection is highly negligible.
