Question

I am working with python.When i try to run my DlgDbError.py file,it gives me error saying:

File "C:\rt_sql_layer\ui\DlgDbError_ui.py", line 47, in setupUi
    QtCore.QObject.connect(self.buttonBox, QtCore.SIGNAL("accepted()"), DlgDbError.accept)
AttributeError: 'DlgDbError' object has no attribute 'accept'

but buttonbox has accept method..what can be the problem??

Answer 1

The error isn’t in your DlgDbError.py file, it’s in the DlgDbError_ui.py module that you created with pyuic4.

This module will contain a Ui_DlgDbError class with a setupUi method. This method has a single argument (named DlgDbError), which takes an instance of the main form class that you created in Qt Designer (i.e. the one also named DlgDbError).

The setupUi method is expecting the DlgDbError object to have an accept() slot, which probably means it should be a subclass of QDialog.

Obviously, you are not passing a subclass of QDialog to setupUi, and so you are getting an AttributeError.

You probably need to do something like this:

from DlgDbError_ui import Ui_DlgDbError

class MyDlgDbError(Ui_DlgDbError):
    def __init__(self, parent=None)
        self.dialog = QtGui.QDialog(parent)
        self.setupUi(self.dialog)
        ...
