SYNOPSIS

#include <Inventor/scxml/SoScXMLZoomTarget.h>

Inherits SoScXMLNavigationTarget.

Public Member Functions

virtual SoType getTypeId (void) const
Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Static Public Member Functions

static SoType getClassTypeId (void)
This static method returns the SoType object associated with objects of this class.
static void * createInstance (void)

static void initClass (void)
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
static void cleanClass (void)
Does the opposite of initClass, deallocates any class specific resources and resets the class to an uninitialized state with respect to the Coin typesystem.

Detailed Description

SCXML event target service for zoom-behaviour.

Events:

SoType SoScXMLZoomTarget::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class. See Also:

SoBase::getClassTypeId

Reimplemented from SoScXMLNavigationTarget.

SoType SoScXMLZoomTarget::getTypeId (void) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting. See Also:

SoBase::getTypeId() const

Implements SoScXMLNavigationTarget.

void SoScXMLZoomTarget::initClass (void) [static]

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. See Also:

SoBase::initClass()

Reimplemented from SoScXMLNavigationTarget.

void SoScXMLZoomTarget::reset (SoCamera *camera) [static]

This function resets the zooming attributes of the camera to the default values.

SbBool SoScXMLZoomTarget::processOneEvent (const ScXMLEvent *event) [protected], [virtual]

This function processes one event. The base class implementation does nothing.

Reimplemented from ScXMLEventTarget.
