Do widgets support introspection?

Only the documented ones.
Even the property inspector shows only the "user_visible" ones.
The only possibility I can see is to scan the lcb file (if it is available).

So, if somebody doesn't document the properties and the widget is not "open source" then you get nothing, whether programatically or not.
