[Pythoncard-users] cvs stable again, openBackground, shell redirect

[Kevin A. <al...@se...>]

I haven't done extensive testing, but cvs seems to be okay for the more
adventurous people on the list. You will need the latest PyCrust from cvs as
well.

The change earlier today added some infrastructure to support background
events. In particular, 'openBackground' which happens after all other
Background initialization and replaces the following two lines in many of
the samples:

    def __init__(self, aParent, aId, aStackRsrc, aBgRsrc):
        PythonCardPrototype.model.Background.__init__(self, aParent, aId,
aStackRsrc, aBgRsrc)

with:

    def on_openBackground(self, source, event):

I'm using openBackground more like the openStack system message in HyperCard
right now, so when we have multiple backgrounds, the usage will change
slightly, since you would only want to init your background once. You'll
also notice that there isn't a name in the method above, which is now true
for any background handler such as the one in tictactoe.py

    def on_bg1_mouseClick(self, button, event):

which is now just:

    def on_mouseClick(self, button, event):

It isn't necessary to provide the name of the background anymore, because
the context is already known.

If you do checkout from cvs, please let me know if you find any problems. I
will be adding additional messages for window resize, window move, idle,
etc. tomorrow if all goes well.

And in case you're wondering, this is sort of tied into my experiments with
scrolling windows and sizers. Scrolling windows looks relatively
straightforward, so I may add that in the next day or two.


Debug menu/Shell feature
I added a "Redirect stdout to shell" option to the Debug menu, so you can
have any print statements in your code, go to the shell instead of the
console. The menu item acts as a toggle, so you can turn it on/off whenever
you like.
