#__selectedness_dirty__Object

Whether selectedness was set via the IDL setter (property), as opposed to only the content attribute — a single-select shows the most recently property-selected option in preference to an attribute-selected one.

#selectedObject

selected is the selectedness state. It is a distinct boolean (the IDL getter returns it directly), initialised from defaultSelected. While the dirtiness flag is false, adding/removing the selected content attribute re-syncs selectedness to it; the IDL setter makes it dirty so it then holds its value independently of the attribute.

def selected=(value)

end

#set_attribute(name, value) ⇒ Object

Keep the selected content attribute and selectedness in sync (while not dirty) by hooking the attribute mutators, the way

tracks open.
