Abstract methods

def attr: Attr[T]
def getProperty[A](control: Control, key: String)(implicit tx: T): Option[A]
def initGraph(g: Graph)(implicit tx: T): Unit

Prepares graph expansion by copying control properties over for subsequent look-up through getProperty.

def nested[A](it: Expanded[T, _])(body: => A)(implicit tx: T): (A, Disposable[T])

Creates a temporary nested context into which all visit calls are redirected, thus a compound Disposable can be returned.

def reactTo[A](event: EventLike[T, A])(fun: T => A => Unit)(implicit tx: T): Disposable[T]

Installs a reaction to an event. Depending on the type of context, this will simply call event.changed.react with the given fun (when the context is for an Act or Control or Widget), or in will register the event as used (when the context is for an ex-obj).
