[vtkusers] Import slot from another .py file

[Helvin Lui]

Hi,
I wanted to use a slot which has been defined in another .py file. (The slot
is called displayMesh, defined in a class called "VTKGraphics", in a file
called "vtkGraphics.py")
However, when I try to connect the slot to a button in my gui, an error
comes up: "NameError: global name 'displayMesh' is not defined. Am I
importing the VTKGraphics class wrongly? I have included the beginning of
each file below.

The main file is like this:

import sys, os, tempfile
from PyQt4 import QtCore, QtGui, QtOpenGL
from ui0 import Ui_main
# Import the VTKGraphics Class from the file called vtkGraphics.py
from vtkGraphics import VTKGraphics

class StartMain(QtGui.QMainWindow):

 def __init__(self, parent=None):
 QtGui.QWidget.__init__(self, parent)
 self.ui = Ui_main()
 self.ui.setupUi(self)
 # Here I want to connect the clicked signal of button_importMesh to the
slot called displayMesh. But an error occurs here.
 QtCore.QObject.connect(self.ui.button_importMesh,
QtCore.SIGNAL("clicked()"), VTKGraphics.displayMesh)

# etc...



My vtkGraphics.py file:

from PyQt4 import QtCore

class VTKGraphics(QtCore.QObject):

    def displayMesh(self):
        import vtk

        with open('C:\\Qt\\SimLCM\\Default\\Data_Input_Geometry.txt', 'r')
as f:
            meshPoints = vtk.vtkPoints()
            aMesh = vtk.vtkVoxel()


          # etc...


I have searched around for quite a bit, but could not find the solution.
Thanks so much guys,
