Deciphering Error Message

wxPython Users
1

When I generate code from wxGlade for my application, I get the attached
scUI.py file. However, when I try to run the file (python scUI.py) I see this
error message:

   File "scUI.py", line 132, in __init__
     self.grid_1 = wx.grid.Grid(self.notebook_1_pane_2, -1, size=(1, 1))
AttributeError: 'module' object has no attribute 'grid'

   The wxWidgets class description doesn't tell me what's wrong. Since this is
my first attempt to use a grid widget I cannot see the error. Please point it
out to me.

Thanks,

Rich

It's missing a:

import wx.grid

Ricardo,

   Hmmm-m-m. Why doesn't 'import wx' import everything? I thought this was
equivalent to 'from wxPython import *'.

Many thanks,

Rich

"import wx" imports all modules in the "wx." namespace, but not other
namespaces - "wx.grid" is a separate namespace.

... and it's in a different namespace, like the HtmlWindow (in wx.html)
because they are more complex controls and we don't need them every
time, avoiding unnecessary load/memory overhead.

At least I think it's the reason for this, someone correct me if I am
wrong.

Horst,

   That's good to know. Where do I find a list of all namespaces? I don't find
such a list in the docs I downloaded.

Thanks very much,

Rich

http://wxpython.org/docs/api/

The top box lists all wx namespaces ("sub-modules") like grid, html etc.

Cheers,
Horst
