# Focus not working in QWizard!
from PySide6.QtWidgets import (QApplication, QWizard, QWizardPage, QLineEdit, QHBoxLayout)
import sys

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

        txt_edit1 = QLineEdit('txt_edit1: Focused: wrong')
        txt_edit2 = QLineEdit('txt_edit2: Focus not set')

        layout = QHBoxLayout(self)
        layout.addWidget(txt_edit1)
        layout.addWidget(txt_edit2)

        # setFocus() line below is ignored! txt_edit1 is still the default
        txt_edit2.setFocus()


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

        self.setWindowTitle("Wizard setFocus() issue")

        self.addPage(ClassInfoPage())


if __name__ == '__main__':

    wizard = MyWizard()
    wizard.show()
    sys.exit(wizard.exec())

Screenshot wrong focus:

The code below works for a window:

# Focus works in normal window!
from PySide6.QtWidgets import QApplication, QMainWindow, QWidget, QLineEdit, QHBoxLayout
import sys

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.setMinimumSize(400, 100)
        self.setWindowTitle("Focus example")

        txt_edit1 = QLineEdit('txt_edit1: Focused: wrong')
        txt_edit2 = QLineEdit('txt_edit2: Focus not set')

        layout = QHBoxLayout()
        layout.addWidget(txt_edit1)
        layout.addWidget(txt_edit2)

        widget = QWidget()
        widget.setLayout(layout)

        self.setCentralWidget(widget)

        # setFocus() works for a normal QMainWindow application!
        txt_edit2.setFocus()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    app.exec()

Screenshot correct focus:

Is setFocus() a bug in QWizard or do I something wrong?
