PyQt: Get the id of a specific QWizard page

Question

I order to design a non-linear wizard with pyqt4 I reimplemented the nextId() function from a PyQt4.QtGui.QWizardPage.

self.page1.nextId = self.nextId_page1

def nextId_page1(self):
    if radio_button.isChecked():
        return 2

    return 3

The code above works fine. But when I insert another page at the beginning of the wizard I need to change the return values (2 and 3) in the function above. I there any possibility to get the id of a specific page? I would like to have something like that:

def nextId_page1(self):
    if radio_button.isChecked():
        return get_id_of_page(name_of_page_2)

    return get_id_of_page(name_of_page_3)

Answer 1

Assuming self refers to the QWizard:

def nextId_page1(self):
    if radio_button.isChecked():
        return self.currentId()+1

    return self.currentId()+2

This is the simple answer.

For arbitrary "go to page":

Note that adding your pages with setPage rather than addPage allows you to explicitly give IDs to each page. page(i) lets you retrieve each page by ID, and pageIds gets a list of currently used Ids; there doesn't seem to be an obvious "which ID is this page", but the two methods before would allow you to quickly find any given page.
