Re: [ptp-dev] Questions about widgets in JAXB plugin

I'm assuming that you are allowing a
general boolean _expression_ with and/or/not and parentheses for both of
these. I think you also need to consider what 'selected' means, where I
think that means selection of widgets with persistent state like checkboxes
and radio buttons as well as text fields which are non-empty (If I enter
data in a field, then that field is 'selected')

I'd suggest getting requests from others
besides me before implementing this since this appears to be sizable work
that I'm not sure I'd use.

Dave,

a few random thoughts before I go out.  Would it be sufficient to
give a widget something like this:

<enabled-if>(widgetA#enabled && widgetB#enabled) | !widgetC#selected</enabled-if>
<visible-if>widgetA#visible && widgetB#visible</visible-if>

The changes I'd have to make:

1.  give all widgets an id that is visible in the configuration
2.  map the widgets to their ids
3.  write a parser for the contents
4.  maintain for each widget a validator for each of its boolean properties
(visible, enabled, selected ...) and run it on each update.

Am I missing something, offhand?

This, as you can see, is not a trivial change, but I'm sure I can make
it work.
