this is more or less to get info for custom usage, bypassing Help,Tip etc,
not that it can't be done, but it's not straightforward,
data(f.e. text)hasToBeDuplicated if custom info is desired.

What sort of info?
all of it would be neat - but for example 'text':
there is a Bar::Item,
then forExample there is ToolButton::text which is set by the Bar::Item overridenFuncs
    ToolButton::text is protected, it could be accessed with subclassing,
    but then again in ToolBar it's defined as Array<ToolButton> item;, so it can't be accessed with subclassing anyway
It's similar for Menu bars.
