Hi all,
i did a small gui addressbook application using pygtk, python, mysql db.
It was successful.
I tried the same application with glade. But i ended up with errors.
I desgined the code as follows.
1.It has one main window and four child dialogs.
2.In the main window, i have to fill in the text entry widget & if i
press 'add', the data will get inserted into the database.This works fine.
3. If showdialog button is clicked, a child dialog appears, where i have
to enter old entry to update.
4. To update, i again use the main window, where i get the following error
Traceback (most recent call last):
File "addressbookglade.py", line 63, in update
self.ssn = self.wTree.get_widget("ssn").
get_text()
AttributeError: 'NoneType' object has no attribute 'get_text'
Also i already set the name in properties window. It works fine for add
option. But not for update option.
Im using the same window for both add and update.
The code is available here http://pastebin.com/m28a4747e
The glade xml file is here http://pastebin.com/m1af61a29
The screenshot of my glade windows are here

You're using instance attributes a lot where I think local variables
would be better, eg "self.ssn" instead of just "ssn".
In the '__init__' method you have:
self.wTree = gtk.glade.XML(self.gladefile,"mainWindow")
and then in the 'view' method you have:
self.wTree = gtk.glade.XML(self.gladefile,"viewdialog")
In both the 'add' and 'update' methods you have:
self.ssn = self.wTree.get_widget("ssn").get_text()
so I suspect that the following is happening:
1. __init__ makes self.wTree refer to 'mainWindow';
2. You click on the Add button, the 'add' method is called, and the
"self.ssn = " line looks for the "ssn" widget in 'mainWindow';
3. You click on the OK(?) button and view what's just been added;
4. The 'view' method makes self.wTree refer to 'viewdialog';
5. You click on the Update button, the 'update' method is called, and
the "self.ssn = " line looks for the "ssn" widget in 'viewdialog'.
