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 Function Documentation

SoType SoButtonEvent::getClassTypeId (void) [static]

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

Reimplemented from SoEvent.

Reimplemented in SoKeyboardEvent, SoMouseButtonEvent, and SoSpaceballButtonEvent.

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

Returns the actual type id of an instantiated object.

Reimplemented from SoEvent.

Reimplemented in SoKeyboardEvent, SoMouseButtonEvent, and SoSpaceballButtonEvent.

void SoButtonEvent::setState (SoButtonEvent::State state)

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.
