help with some problems on Tutorial 1 for GladeVcp

I finally got glade installed properly and started following the tutorial at this location: . The URL is gnipsel.com/linuxcnc/gui/gui01b.html
I did a copy and paste of the code but built the glade file from scratch. When I follow the instructions I get the following error messages in the terminal:

What am I doing wrong?

you obviously pasted python code into a shell window

save the code in a file, say example.py

then run it with

$ python example.py

I tried that first and the terminal screen just flashed and disappeared. The gui didn't show up.

I removed the pygtk require ("2.6") line and it finally ran, sort of. Here is the ouput result:

gui1.py:23: RuntimeWarning: missing handler 'on_window1_destroy'
self.builder.connect_signals(self)
gui1.py:23: RuntimeWarning: missing handler 'on_quit_activate'
self.builder.connect_signals(self)
Traceback (most recent call last):
File "gui1.py", line 30, in <module>
app = gui_one()
File "gui1.py", line 25, in __init__
self.window.show()
AttributeError: 'NoneType' object has no attribute 'show'

John's turtorial has:
pygtk.require("2.0") which is not the same as 2.16 or 2.6

The last problem you have is most likely that the window in the glade file is not named right.
Default name in GLADE is window1, John's python program expects it to be MainWindow
change one of them.

John you shouldn't be so tricky to newbies

You're right about window1 and MainWindow. I printed out all of the tutorial pages and didn't notice the change so i was using window1 while the code I pasted called for MainWindow. Runs fine now except for the quit button in the menu but I can fix that.
I really appreciate the help. I've been using Linuxcnc for about two years but this is the first I've ever tried to customize a control panel.

Things are moving along nicely. These are great tutorials but I've run into a snag with the python file from part 3b where we create a standalone sim gui. The error occurs at this line:
libdir = os.path.join(BASE, "lib", "python")
And the message simply states : syntax error: invalid syntax
Any ideas?

It tried the code on Johns page and found no syntax errors.
I didn't have the glade file so can't say if it actually works ..
make sure you typed it right.
