Re: [Dynapi-Widgetdev] "Menu" list.js widget fixes

[Robert R. <rra...@ya...>]

We should really create a style object (there use to be one). This
object would define all the different methods needed to change font
styles. It would also allow for the writing of font strings. Then,
this object could be used by many of the widgets. Most of the widgets
now do not allow the changing of font styles very easily because that
is really the last thing you do once the widgets are stable.
