## Detailed Description

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).

## 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::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.

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 | ( | State | enumval,
|  | 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.

Since
  Coin 3.0
