[Newb] Still not able to solve class attribution

[Knoppix User]

Hi folks

I still have not been able to solve this one, which didn't manage to
garner a response yesterday, so I'm rephrasing it here.

If I define an attribute in the __init__ statement of a class, I should be
able to access that attribute in a later method of that class, right?

I have run into a situation where that does not SEEM to happen [newbie
alert].

What should I be looking into to try to solve this bug, as I am SOL with
new ideas?!

Although I am using wx, I do not believe that this has anything to do with
wx, but with syntax / semantics.

Any thoughts are very much appreciated.

I copy the original question below, for convenience.

class GIP(wx.Frame):
def __init__(self, parent, ID, title):
wx.Frame.__init __(self, parent, ID, title, size = (600, 460))

....

self.Image = wx.StaticBitmap (self, -1, wx.EmptyBitmap( *self.thumbSize ),
pos = (160,10)) <<<<<<<<<<<<<<< <<<<<I thunk I dunnit here!

....

def DisplayImg(self , rot):
self.SetStatusT ext('Current image: ' + self.jpgList[self.curJpg])
img = wx.Image(self.j pgList[self.curJpg], wx.BITMAP_TYPE_ JPEG)
if rot == 90:
img = img.Rotate90()
elif rot == 180:
img = img.Rotate(1, (0,0))
elif rot == 270:
img = img.Rotate(1.5, (0,0))
img = self.ScaleImg(i mg)
img = wx.BitmapFromIm age(img)
self.Image.SetB itmap(img) <<<<<<<<<<<<<<< <<<<<<<<Probl em

Just an idea: how about moving the following statement up immediately after
the wx.Frame.__init __(...). The DisplayImg() method *could* be called in
the code you abbreviate with the above four dots.
self.Image = wx.StaticBitmap (self, -1,
wx.EmptyBitmap( *self.thumbSize ),
pos = (160,10)) <<<<<<<<<<<<<<< <<<<<I thunk I dunnit here!

Thanks for the idea Peter. No go. I did think of that earlier, and checked
a printout very carefully to make sure about that.

Anyway, I did move it up to be the first method after __init__, just to
check again.

You were on the right track, Peter!

Your comment go me thinking some more. The error was not in the last line,
but the second to last.

I have quite a long init method, and the conflict was between the code
that sets up the StaticBitmap, and a prior reference to that code, from a
Button.

Thanks for jarring my mind-track in the right direction!!!!
