Detailed Description

Base class for objects providing an input of any kind.

It extends the ValueNotifier class by a reference to a VParameter base class.

Note

Call activateNotification() after construction.

Constructor & Destructor Documentation

VInputBase()

Wizt::VInputBase::VInputBase

(

const WeakPtr< VParameter > &

owner

)

Construct a new input base type.

The creation preferences of the owner might influence the properties of this input, for instance if the "local" property is found in the creation preferences of the owner, then a context-local variable is created.

Note

Call activateNotification() after construction

Member Function Documentation

activateNotification()

bool Wizt::VInputBase::activateNotification

(

)

const

Allow the owner of this InputBase to retrieve notification events when the value is changed.

Note

The function MUST NOT be called until this has been assigned to a strong reference pointer! In particular, it MUST NOT be called in the constructor!!

References MemCore::ReferenceBase< ValueNotifier >::self().

notify()

void Wizt::VInputBase::notify	(	const ValueNotifierList *	Source,
		const Wizt::ValuePoolPtr &	Ctx
	)		const

Emit a notification event to all ValueNotifiers listening on the certain variable.

Parameters

Source

The notification event is only broadcasted if the owner is not the source of the event.
