[Libvisual-devel] VisObject

[Dennis S. <sy...@yo...>]

Some random thoughts on VisObject:

Object hierachy:
VisObject
	VisUI
		VisUI...
	VisActor
	VisInput
	VisPlugin
	etc


Implement Ref counting at VisObject layer.

Most important API addition for now:
	visual_object_ref (VisObject *object);
	visual_object_unref (VisObject *object);

VisObject {
	int refcount;
	VisObjectDtorFunc dtor;
}

Example for a random structure:

VisActor {
	VisObject object;

	blah;
	blah;
}

visual_actor_new ()
{
	VisActor *actor = ...

	VISUAL_OBJECT (actor)->dtor = dtor_actor;

}

visual_object_unref (obj)
{
	obj->ref--

	if (obj->ref <= 0)
		obj->dtor (obj);
}

Problems to be solved:
How to implement the automatic dtorring.

Being able to set a dtor for an object ?

This could also exterminate the ugly switches in VisUI that are used for
a VisUI object dtoring.
