Question

I have created my GUI using wxGlade and it looks fine in the display. I am now trying to run the code it generated before adding it to my finished Python program. I have tryed copying it in to the file structure and running it then copying the code into a new file. I have check the files needed are on the pythonpath and they are all. Everytime I get this same error message. Error message

Traceback (most recent call last):
  File "C:\Users\Steb\workspace\Check\GuiAttempt.py", line 85, in <module>
    frame_4 = FirstScreen(None, -1, "")
  File "C:\Users\Steb\workspace\Check\GuiAttempt.py", line 21, in __init__

I am using Python 2.7, my IDE is eclipse indigo with PyDev.
Please help.

Your problem is with this:

self.Title = wxPanel(self, -1, style=wxDOUBLE_BORDER|wxTAB_TRAVERSAL)

You have named a panel Title, but Title is a propery that expects a string or unicode.

If you rename Title to something else (like MyTitle), your code will work.

Do a Find > Replace in your favorite editor and change all instances of self.Title to self.MyTitlePanel (for example) save the file and run it again.
