Hello,
My first post here, and also my first python app.
I'm having trouble getting my Qt3 app wotking in Qt4. I have designed
the UI in QT-Designer and ported it to Qt4 with uic3 -convert, and
removed all Qt3 support widgets. When I run the .py it complains:
Traceback (most recent call last):
File "testapp.py", line 100, in ?
app = HelloApplication(sys.argv)
File "testapp.py", line 20, in __init__
self.maindialog = TestAppUI(None)
File "testapp.py", line 31, in __init__
self._connectSlots()
File "testapp.py", line 42, in _connectSlots
self.connect(self.addbutton,SIGNAL("clicked()"),self._slotAddClicked)
AttributeError: 'TestAppUI' object has no attribute 'connect'
Is this a change in QT, or one of my mistakes?
The .ui and .py Files are attached.
Thanks, Lawrence
