Open a new window after Finish Button has been clicked on Qwizard : Pyqt5

I want to have the finish button on my QWizard do something else besides exit the page. I need to connect it to a function that calls another window. In other words, I need to view and add functionality to the Finish Button of the Qwizard page. Does anyone know how to do this. Thanks

Its mostly the same you are already used to do in PyQt. The differences are in how to find the Finish button entity. Here is a working example:

import sys
from PyQt5 import QtWidgets, QtCore, QtGui

class IntroPage(QtWidgets.QWizardPage):
    def __init__(self, parent=None):
        super(IntroPage, self).__init__(parent)

class LastPage(QtWidgets.QWizardPage):
    def __init__(self, parent=None):
        super(LastPage, self).__init__(parent)

class MyWizard(QtWidgets.QWizard):
    def __init__(self, parent=None):
        super(MyWizard, self).__init__(parent)

        self.introPage = IntroPage()
        self.lastPage = LastPage()
        self.setPage(0, self.introPage)
        self.setPage(1, self.lastPage)

        # This is the code you need
        self.button(QtWidgets.QWizard.FinishButton).clicked.connect(self._doSomething)

    def _doSomething(self):
        msgBox = QtWidgets.QMessageBox()
        msgBox.setText("Yep, its connected.")
        msgBox.exec()

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    main = MyWizard()
    main.show()
    sys.exit(app.exec_())

Notice how I used this command: self.button(QtWidgets.QWizard.FinishButton) to specifically point to the finish button. The rest is just build your own method to do whatever you need. In my example I connected to def _doSomething(self) and launched a very simple QMessageBox.
