    Hi,

    How do you want to do that from a button ?

    @SGaist you could imagine it as a setup wizard more or less, with 'next' or 'back' buttons

        I said Setup Wizard as an example, what I exactly want is a main menu from where you can go to different interfaces, so I need buttons to go through pages. (This app is going to be running on a Raspberry Pi 2 using EGLFS)

          ok
          QStackedWidget seems right for a multipage application.

            @mrjj So what I did so far is that when I clic the button it declares an int with the index number, now I could set the variable I declared as the index for my QStackedWidget right ?

              @mrjj More or less like this:

              
              void MainWindow::on_Cambio1_clicked()
              {
                  int cambio1;
                  cambio1 = 0;
                  void QStackedWidget::setCurrentIndex(cambio1);
              }
              

              I don't know why but it comes up with this error:

              error: invalid use of qualified-name 'QStackedWidget::setCurrentIndex'
                   int QStackedWidget::setCurrentIndex(cambio1);
                                                              ^

                well i would expect something like
                void MainWindow::on_Cambio1_clicked()
                {
                // int cambio1; <<< move to mainwinow.h in the class so all buttons have access to this "current-page"
                cambio1++; // take next page//
                ui->YourQStackedWidget->setCurrentIndex(cambio1);
                }
                set cambio1= 0 in mainwin constructor

                A more clean way might be to use to functions
                nextPage() and prevPage() in mainwindow
                and the buttons just call that and it does the page switch back and forth.

                please try this sample

                  The error comes from the fact that your are trying to call a class method like it's a static method.

                  Even if you don't use QWizard, you can take a look at its implementation to get started.

                        Yes, u can have buttons inside the pages if you want.
                        Works the same.

                          @mrjj Hi! I managed to make everything just as I wanted, everything is going fine. The code example you sent me really did the trick. Thanks a lot.
