NAME

       SoButtonEvent -

       The SoButtonEvent class is the base class for all button events.

       The event classes which results from the user pushing buttons on some device (keyboard,
       mouse or spaceball) all inherit this class. The SoButtonEvent class contains methods for
       setting and getting the state of the button(s).

SYNOPSIS

       #include <Inventor/events/SoButtonEvent.h>

       Inherits SoEvent.

       Inherited by SoKeyboardEvent, SoMouseButtonEvent, and SoSpaceballButtonEvent.

Member Enumeration Documentation

   enum SoButtonEvent::State
       This gives the actual state of the button.

       Enumerator

       UP     Button has been released.

       DOWN   Button has been pressed down.

       UNKNOWN
              The state of the button is unknown.

Constructor & Destructor Documentation

   SoButtonEvent::SoButtonEvent (void)
       Constructor.

   SoButtonEvent::~SoButtonEvent () [virtual]
       Destructor.

Member Function Documentation

   SoType SoButtonEvent::getTypeId (void) const [virtual]
       Returns the actual type id of an instantiated object.

       Reimplemented from SoEvent.

       Reimplemented in SoKeyboardEvent, SoSpaceballButtonEvent, and SoMouseButtonEvent.

   void SoButtonEvent::initClass (void) [static]
       Initialize the type information data.

   void SoButtonEvent::setState (SoButtonEvent::Statestate)
       Set the state of the button which the user interacted with.

       This method is used from the window specific device classes when translating events to the
       generic Coin library.

       See Also:
           getState()

   SoButtonEvent::State SoButtonEvent::getState (void) const
       Returns the state of the button which is the cause of the event, i.e. whether it was
       pushed down or released.

       See Also:
           wasShiftDown(), wasCtrlDown(), wasAltDown(), getPosition(), getTime()

   SbBool SoButtonEvent::enumToString (Stateenumval, SbString &stringrep) [static]
       Converts from an enum value of type SoButtonEvent::State to a string containing the enum
       symbol.

       This function is an extension for Coin, and it is not available in the original SGI Open
       Inventor v2.1 API.
