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.

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.

void SoButtonEvent::initClass (void) [static]

Initialize the type information data.
