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.

Detailed Description

       SCXML event target service for zoom-behaviour.

       Events:

       x-coin-navigation.Zoom.*

       { BEGIN _sessionid {string} mouseposition {SbVec2f}

       UPDATE _sessionid {string} mouseposition {SbVec2f}

       END _sessionid {string} mouseposition {SbVec2f} }

       ZOOM _sessionid factor {float}

       ZOOM_IN _sessionid {string} [factor] {float=1.2} [count] {float=1}

       ZOOM_OUT _sessionid {string} [factor] {float=1.2} [count] {float=1}

       RESET _sessionid {string}

Member Function Documentation

   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::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.
