QDialog override reject when loading .ui file

[tilz0R]

I have a custom dialog that is based on QDialog class. I load .ui file to python.

# Main window class
class MyDialog(QDialog):
    def __init__(self):
        super().__init__()
        self.load_ui()
        self.ui.show()

    # Load UI from file
    def load_ui(self):
        loader = QUiLoader()
        path = os.fspath(Path(__file__).resolve().parent / 'ui' / 'dialog.ui')
        ui_file = QFile(path)
        ui_file.open(QFile.ReadOnly)
        self.ui = loader.load(ui_file, parentWidget = self)
        ui_file.close()

    # Override reject
    def reject(self):
        print("reject")

I call it with self.testwidget = MyDialog() and it opens well. But reject method is not part of the UI. How can I add reject method if UI is loaded from .ui file? I want to do something on reject callback.

Hi,

The recommended way to use designer based widget is to generate the Python code from your ui file.

Thanks - is there a way to create ui_xxx.py file directly when you save .ui file in QtCreator ?
