self.modelTree = self.uiMainWindow.uiModelTree # This is where I get the error
self is referring to your instance of ModelWindow, but you store
uiMainWindow in the instance of MainWindowSetup.
If you want to access that, you’ll need to pass a handle to it. It’s
typically done using a parent, but you aren’t including the parent in your
__init__ method.
Try something like this.
class MainWindowSetup(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self)
self.uiMainWindow = Ui_MainWindow()
self.uiMainWindow.setupUi(self)
self.uiModelWindow = ModelWindow(self)
class ModelWindow(QtGui.QTreeWidget):
def __init__(self, parent):
print "!! Initialised model window"
QtGui.QTreeWidget.__init__(self, parent)
self.modelTree = parent.uiMainWindow.uiModelTree # This is
where I get the error
