I have a three pages wizard. First page is BasicSettings(), second page is InstallPackages() and the last page is Summary().
I want the Next button on the first page to first execute a method named execute_venv_create() and then call the next page. On the following pages, the Next button should behave as usual.
For this I connected the Next button to execute_venv_create() like this:
class VenvWizard(QWizard):
"""The wizard class."""
def __init__(self):
super().__init__()
# ...
class BasicSettings(QWizardPage):
"""This is the first page."""
def __init__(self):
super().__init__()
# ...
def initializePage(self):
next_button = self.wizard().button(QWizard.NextButton)
next_button.clicked.connect(self.execute_venv_create)
def execute_venv_create(self):
# do something, then display an info message
QMessageBox.information(self, "Done", "message text")
The problem is that of course the method is called every time I click Next and therefore I tried to disconnect the button and reconnect it to the QWizard.next() method in this way:
class InstallPackages(QWizardPage):
"""This is the second page."""
def __init__(self):
super().__init__()
# ...
def initializePage(self):
next_button = self.wizard().button(QWizard.NextButton)
next_button.disconnect()
next_button.clicked.connect(QWizard.next)
On the first page the Next button works as I expect, it calls the method and switches to the next page. But then, on the second page InstallPackages(), the GUI crashes if I click Next.
Is this the right way to connect a QWizard button to a custom method or is it not possible to use wizard buttons from QWizardPages?
How to connect the QWizard.NextButton to a custom method of a specific QWizardPage and make the button behave as usual on the following pages?
