about about my xo

[Erik Blankinship]

Hi Chris!

I tried:

* Looking at an up-to-date activity for best practices.  In this case I
looked at TurtleArt 106 and saw this code:

from sugar.activity import activity
try:  # 0.86 toolbar widgets
    from sugar.activity.widgets import ActivityToolbarButton, StopButton
    from sugar.graphics.toolbarbox import ToolbarBox, ToolbarButton
    NEW_SUGAR_SYSTEM = True
except ImportError:
    NEW_SUGAR_SYSTEM = False

Alas, this did not provide the granularity I was hoping to find.  I can
however appreciate why this type of check might have been written to ensure
backwards compatibility.
* I looked in the book "Make Your Own Sugar Activities!" and the sugar
almanac but did not find the answer.
* Since I am not a system developer, I wrote to these lists to ask how an
activity developer should properly query this information.  When I find
myself breaking an abstraction barrier from activity into system I often
feel I have overlooked something or am building something fragile.  Thank
you for your answer.

It might be a good idea for the sugar api to make this type of information
readily available to developers in future releases.
