Chris:
I, too, have been fighting with this for about two weeks. (Two newbies
with the same problem.) The documentation of wx.StaticBitmap is too sketchy
for me to tell what magic each incantation (method) is supposed to perform.
How does one get the new bitmap for .SetBitmap(bitmap)???
Would you be so kind as to provide a version of Steve's showJpg function
which will do what he (and I) wish to accomplish? It HAS to be more simple
than I am making it!

All works as planned, except that the image displayed, being correct,
first shows, in rapid succession, each of the prior showed images
beforeit halts at the appropriate curFile.
THis is exacty what you have asked it to do..each call to showJpg
creates a new wxStaticBitmap on top of all the old ones. What you want
to do is create a single wxStaticBitmap, and then change the bitmap on
it with:
wxStaticBitmap.SetBitmap(bitmap)

You'll get the hang of the docs soon enough. They really are reference docs, not tutorials. Have you searched both the demo and Wiki for wxStaticBitmap? I alwyas look for examples to modify when I'm trying to get the hang of a new class.

The same why you get the bitmap for the constructor call.

I don't know what you're doing, but it's pretty simple. I've enclosed a sample app that displays a set of jpgs in an "Image directory".
There have been enough questions about this, I just may put this in the Wiki.

It is very simple. Save a reference to the wxStaticBitmap when it is created, and then use that reference to call SetBitmap when needed.
# in __init__ or somewhere
self.stbmp = wxStaticBitmap(self, -1, aBitmap, pospos=(245, 60),
size=(100,100))
...
I agree, about how simple Python is. I am a raw beginner, but find
myself guessing, when I cannot find the appropriate docs, and am
(already) sometimes right!
I found this on the comp.lang.python list:
.....
About a year ago, I felt the same way about the lack of elementary
wxPython docs as you do. It seems that everyone who has had that
complaint either goes away or sticks with it for a week or two and
figures it out and then there is no problem. Not to make light of
your frustration, but this question is some ways similar to "Why
aren't there any good books for beginners on how to ride a bicycle?"
.....
It reminds me about my (much) earlier days with dBIII (remember that?).
Although the documentation was easier to get at, the main thing about
the learning curve was learning to think in the dBIII paradigm, and
suddenly, everything seemed intuitive.
Seems to me Python is even more so.
