[Help]: How to make a QWizardPage unvisited?

[dongli]

Hi, everyone

I want to create a wizard with some kind of loop, so how to make a visited page unvisited?

Thanks for advance!

Take a look at QWizard::nextId(), it helps you create a non-linear wizard.

QWizard::nextId() doesn't allow to make loops, because as soon as you come back to a page you already visited, QWizard won't let you visit it again.

The source: qwizard.cpp explicitly shows that this is impossible:

void QWizard::next()
{
    Q_D(QWizard);
 
    if (d->current == -1)
        return;
 
    if (validateCurrentPage()) {
        int next = nextId();
        if (next != -1) {
            if (d->history.contains(next)) {
                qWarning("QWizard::next: Page %d already met", next);
                return;
            }
            if (!d->pageMap.contains(next)) {
                qWarning("QWizard::next: No such page %d", next);
                return;
            }
            d->switchToPage(next, QWizardPrivate::Forward);
        }
    }
}

void QWizard::next()
{
    Q_D(QWizard);

    if (d->current == -1)
        return;

    if (validateCurrentPage()) {
        int next = nextId();
        if (next != -1) {
            if (d->history.contains(next)) {
                qWarning("QWizard::next: Page %d already met", next);
                return;
            }
            if (!d->pageMap.contains(next)) {
                qWarning("QWizard::next: No such page %d", next);
                return;
            }
            d->switchToPage(next, QWizardPrivate::Forward);
        }
    }
}

To copy to clipboard, switch view to plain text mode 

Has anyone got an idea of a way to force visiting a page, or to remove a page from the history, or to disable storing pages in the history? (Let's see if people still visit threads from 2009 ^^)

Maybe calling back() until the current page is the one you want to return to?
