Member Function Documentation

SoType SoButtonEvent::getTypeId (void) const [virtual]Returns the actual type id of an instantiated object​. Reimplemented from SoEvent​. Reimplemented in SoSpaceballButtonEvent, SoMouseButtonEvent, and SoKeyboardEvent​.

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) constReturns 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​.
