QStackedWidget setCurrentIndex slot not showing on Signals&Slots editor (QtCreator)

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

@cxam
just to be sure, u did see
http://doc.qt.io/qt-5/qwizard.html
which is for wizard type of interface.

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)

[mrjj]

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 ?

[cxam]

@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);
                                                ^

@cxam
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.

@SGaist @mrjj thank you very much for your help, I'll try that out and see how it goes.

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.
