DESCRIPTION¶

SoButtonEvent represents generic button press and release events in the Inventor event model. It is the base class for device-specific button events, namely SoKeyboardEvent, SoMouseButtonEvent, and SoSpaceballButtonEvent. This class stores the down/up state of the button when the event occurred.

METHODS¶

SoButtonEvent()

Constructor.

static SoType getClassTypeId()

Return the type id for the SoButtonEvent class.

void setState(SoButtonEvent::State s)

SoButtonEvent::State getState() const

Set and get the state of the button.
