[Pythoncard-users] major cvs update - modular widgets

I finally got everything working correctly after some major modifications.
Of course, there are probably still bugs, but I think I managed the first
step of modularizing widgets.py without breaking all the samples. This
version doesn't support a widgets/components path, it always expects to find
components in the new components directory, but it should be relatively easy
to add support for additional directories. I expect to refactor the code to
be cleaner, since this version still uses spec.py for all the non-widget
classes like Stack and Background.

Basically, I needed to check what I have right now into cvs, so Rowland,
Jeff, and anyone else that wants to help with the modularization and
components transition can start providing input. Adding a new widget should
be as simple as creating a new module with the spec, class, and event
bindings and dropping it into the components directory.

I also took this opportunity to bump up the requirements to wxPython 2.3.2
and I cleaned up all the
  from wxPython.wx import *
import statements, which impacted almost every framework file and many of
the samples. Now it is easy to know whether something comes from wxPython,
because it will always have a "wx." in front of a class, method, or
constant.

The list of changes is below.

---
*** wxPython 2.3.2 or later is now required to use PythonCard ***
added assert wxc.__version__ >= "2.3.2" to model.py
changed wxPython imports from
  from wxPython.wx import *
  to the more explicit
  from wxPython import wx
  added missing imports such as 'import types' where needed
replaced occurances of wx.true and wx.false with 1 and 0
added a components directory
merged wxPython_binding.py into binding.py and moved widget-specific
  bindings to individual module files
moved spec.py descriptions for each widget to its respective widget
  module
split widget.py so each widget is in its own file in the components
  directory
  all widgets (components) are now self-contained modules in the
  components directory. each module includes the spec, event bindings,
  and attribute descriptions (formerly in spec.py) in addition to the
  widget class. when the module is imported it "registers" itself, so
  that the class is available for applications.
added drawPointList and drawLineList (2.3.2 feature) to the
  BitmapCanvas widget, switched to drawPointList in hopalong sample
  for a roughly 4x speed improvement
updated the setup.py script for minimal.py and provided some basic
  instructions in the readme.txt. It is necessary to uncomment the
  import in minimal.py prior to using py2exe due to how the dynamic
  imports are done for components
