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.

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.
