Detailed Description

Represents Inline node instances.

openvrml::vrml97_node::inline_node::inline_node	(	const node_type &	type,
		const scope_ptr &	scope
	)

Construct.

Parameters:

type	the node_type associated with this node.
scope	the scope to which the node belongs.

void openvrml::vrml97_node::inline_node::activate	(	double	time,
		bool	isOver,
		bool	isActive,
		double *	p
	)	`[virtual]`

Pass on to enabled touchsensor child.

const std::vector< node_ptr > & openvrml::vrml97_node::inline_node::children ( ) const throw () [virtual]

Get the children in the scene graph.

void openvrml::vrml97_node::inline_node::process_set_url	(	const field_value &	value,
		double	timestamp
	)	throw (std::bad_cast, std::bad_alloc) `[private]`

set_url eventIn handler.

Parameters:

value	an mfstring value.
timestamp	the current time.

Exceptions:

std::bad_cast	if `value` is not an mfstring.
std::bad_alloc	if memory allocation fails.

Todo:: Currently this only changes the field value; it does not load a new Scene.

void openvrml::vrml97_node::inline_node::render	(	openvrml::viewer &	viewer,
		rendering_context	context
	)	`[virtual]`

Render the node.

Render each of the children.

Parameters:

viewer	a Viewer.
context	a rendering context.

Reimplemented from openvrml::node.

inline_node * openvrml::vrml97_node::inline_node::to_inline ( ) const [virtual]

Cast to an inline_node.
