I recently picked up wxPython In Action and installed
1) Python 2.5.1 and wxPython 2.8.3 on my mac osx 10.4.9 system
2) Python 2.4.4 and wxPython 2.6.3 on my linux fc6 machine.
In running through some examples from the source code in the wIA book
I found that the Grid examples in Chapter 14 did not work properly.
In particular, when scrolling the grid ( grid_table.py in chapter 14)
using the scrollbars I found that the row and column headers did not
scroll with the table!
I found that if I forced an update by resizing the window header would
be redrawn properly... It appears that the row/column headers are not
being properly updated when the scrollbars are used.
Using the "arrow" keys does cause the row/column heads to be properly
updated.

The examples *did* work on my linux box.
Is this a known problem?
Yes. I thought it was fixed already, but I see that it is still happening in my local workspace. I'll look into it again.
BTW, you can workaround this in the meantime by forcing a cell editor to be created, because once the grid has a child window then the optimization that causes this problem is not used. Something like this:

I don't seem to be able to create the editor ( probably because it
is all new to me).
I *can* click in a cell and then scrolling works properly. I tried this
but I don't get the cell editor ;(
It will work if you delay the hack until later, after the grid has had a chance to paint itself and finish configuring itself. wxPython provides the wx.CallAfter function to help with things like this, it allows you to have a function called when the app is next idle:
class TestFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, title="Grid Table",
size=(640,480))
