    well its
    class IPCtrl : public QFrame

    so yes you can use that directly.

        Hi
        the first parameter needs to be a QLabel and u give it a char *
        also it seems that ip_field is not pointer ?

          @mrjj Actually it is ok with the Char* in place of the QLabel, so I would put that apart for now.
          I tried to:

          • declare IPCtrl *ip_field (a pointer, as you suggested) in mainwindow.h

          • write ui->formLayout->addRow("IP Address", ip_field->window()); ip_field->show(); (then with the arrows in place of the dots) in mainwindow.cpp

          the application starts but the UI won't just appear...

            @Tamfub

            Ok the window() part makes no sense to me.

            Looking at the code, it just seems like a normal custom widget.
            Did you change the code shown on SO or used it as is ?

                Ok i did fast test.
                It just compiles so not sure why you get so much grief from it :)

                ui->formLayout->addRow("test", field);

                alt text

                test project.

                  @mrjj Ok, it worked also for me now, the error in addRow disappeares when ip_field is declared as a pointer. I did not try this XD

                  Thank you very much!

                    Np :)
                    yes it must be pointer OR you must use the & to take address but
                    due to how deletion works, it's best to use pointer :)

                      @mrjj Got it! Do you know why the right border of the textEdit is not visible?

                        It seems the last Edit touches the QFrames border.
                        but even if i make it HUGE, it still happens so its
                        its seems to be due to
                        pLayout->setContentsMargins( 0, 0, 0, 0 );
                        so you can fix it with
                        pLayout->setContentsMargins( 0, 0, 1, 0 );
                        Seems not to give ill side effects.

                        ps. in
                        IPCtrl::IPCtrl(QWidget *parent) : QFrame(parent)
