If something hits you on the head, don't run around screaming that the

sky is falling. Instead, take a close look and see if it wasn't a

Yes, the world is changing, and even our little wxPython world must

change with it. Then again, I'm not fond of pesky summertime flies,
|
||||
and I'm not too upset that the "wx" prefixes are going to bite the
|
||||
dust. I think it's for the best. But, being the kind, considerate

namespace transition easier for everyone, even Chicken Little.

If you have no idea what I mean by the "wx namespace transition,"
|
||||
consider yourself lucky. You can simply use these examples to

||||
learn wxPython in its current state. All you need to know is that
|
||||

|
||||
folks (including me) considered ugly. So we changed it. And
|
||||
that's when the sky starting falling...
|
||||
|
||||
Rather than simply **tell** you that everything will be okay, I
|
||||
decided to **show** you that everything will be okay. To do that,
|
||||
I've created a bunch of example programs using the new wx package. I
|
||||
hope you like them.

Basic
|
||||
=====
|
||||
|
||||
It doesn't get much simpler than this. Every wxPython program needs
|
||||
an application and a frame. To encourage good coding habits, I've
|
||||
split them into separate modules. They don't do much, but they're a
|
||||

|
||||
|
||||
I include a simple App class in the frame module because the PyCrust
|
||||
"wrapper" utility (``wrap.py``) only works with modules that contain
|
||||
an application class. So including a simple one in each of your frame
|
||||
modules allows you to use the PyCrust runtime wrapper and debug your
|
||||
frames independent of your full application.
|
||||
|
||||
Here is the module (``frame.py``) that defines the frame class:
|
||||
|
||||
.. include:: basic/frame.py
|
||||
:literal:
|
||||
|
||||
And here is the module (``app.py``) that defines the application class
|
||||
and imports the frame from ``frame.py``:
|
||||
|
||||
.. include:: basic/app.py
|
||||
:literal:
|
||||
|
||||
