DESCRIPTIONSoEvent is the base class for events in the Inventor event model. An
event typically represents a user action, such as a mouse button being
pressed or a keyboard key being released. SoEvent contains general
information found in all Inventor events, including the time the event
occurred, the position of the locater when the event occurred, and the
state of the modifier keys when the event occurred.
FUNCTIONSSoEvent * SoEvCreate()
void SoEvDelete(SoEv *this)
Constructor and destructor.
SoType SoEvGetTypeId(const SoEv *this)
Return the type id for this event instance.
SoType SoEvGetClassTypeId()
Return the type id for the SoEvent class.
Page 1SoEvent(3IV)
SbBool SoEvIsOfType(const SoEv *this, SoType type)
This returns TRUE if the event is an instance of or derived from an
event of the passed type.
void SoEvSetTime(SoEv *this, SbTime t)
SbTime SoEvGetTime(const SoEv *this)
Set and get the time at which the event occurred.
void SoEvSetPos(SoEv *this, const SbVec2s *p)
const SbVec2s * SoEvGetPos(const SoEv *this)
Set the window pixel location of the cursor when the event occurred.
The position is relative to the lower left corner of the window in
which the event occurred.
const SbVec2s * SoEvGetPosInVP(const SoEv *this, const
SbViewportRegion *vpRgn)
Get the viewport pixel location of the cursor when the event
occurred, relative to the specified viewport region.
const SbVec2f * SoEvGetNormPos(const SoEv *this, const
SbViewportRegion *vpRgn)
Get the normalized location of the cursor when the event occurred,
relative to the specified viewport region. The returned value will
lie between 0.0 and 1.0.
void SoEvSetShiftDown(SoEv *this, SbBool isDown)
void SoEvSetCtrlDown(SoEv *this, SbBool isDown)
void SoEvSetAltDown(SoEv *this, SbBool isDown)
Set whether the modifier keys were down when the event occurred.
SbBool SoEvWasShiftDown(const SoEv *this)
SbBool SoEvWasCtrlDown(const SoEv *this)
SbBool SoEvWasAltDown(const SoEv *this)
Get whether the modifier keys were down when the event occurred.
