Re: Using BarChart in a Widget


Hi Jeff,

Thank you for your message.

In the interim, I did find a solution to the problem I had by using
the IncludedScriptContexts option.

However, your suggestion is clearly preferable by not exposing the GUI
to the Global Mathematica context-space.

I did try to implement something along the same lines myself, by
putting the Needs commands in the same Script as my function
definitions. This did not work, unless I also used the
ToExpression["<context>`<function_name>"] syntax, which was both ugly
and non-obvious.

In fact, I consider it highly counter-intuitive that the Needs command
only works when it is in a *separate* Script.

One other thing you may be able to help me with: can you tell me where
I can find documentation on all the available widgets, their
properties, and events. For example, the MathPanel widget, or the
Dimensions widget, or the mathCommand property of the MathPanel
widget. I have only learnt about these from examples, and I really
don't know what their full functionality is.

Thanks again for your help.
