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.

SoButtonEvent::SoButtonEvent (void )

Constructor.

SoButtonEvent::~SoButtonEvent () [virtual]

Destructor.

SoType SoButtonEvent::getClassTypeId (void ) [static]

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

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

Returns the type identification of an object derived from a class inheriting SoEvent. This is used for runtime type checking and 'downward' casting.

Reimplemented from SoEvent.

Reimplemented in SoKeyboardEvent, SoMouseButtonEvent, and SoSpaceballButtonEvent.

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

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

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.
