Coin contains its own set of event classes, independent of the underlying window system. Upon system specific events, a translation is done by the window specific device classes into one of the Coin event object classes listed below. The event is then typically sent by the render area to an SoSceneManager which will apply it to the scene graph through an SoHandleEventAction. Events may be caught by the user by attaching an SoEventCallback node to the scene graph, or they can automatically be handled by a dragger or manipulator in the graph. See also SoButtonEvent, SoKeyboardEvent, SoLocation2Event, SoMotion3Event SoMouseButtonEvent, SoSpaceballButtonEvent SoEventCallback, SoHandleEventAction Constructor & Destructor Documentation SoEvent::SoEvent (void ) Constructor, will set all modifiers to 'off' state. SoEvent::~SoEvent () [virtual] Destructor. Member Function Documentation SoType SoEvent::getClassTypeId (void ) [static] This static method returns the SoType object associated with objects of this class. This static method returns the SoType object associated with objects of this class. SoType SoEvent::getTypeId (void ) const [virtual] Returns the type identification of an object derived from a class inheriting SoEvent. This is used for runtime type checking and 'downward' casting. Returns the actual type id of an instantiated object. Reimplemented in SoButtonEvent, SoKeyboardEvent, SoLocation2Event, SoMotion3Event, SoMouseButtonEvent, and SoSpaceballButtonEvent. void SoEvent::initClass (void ) [static] Initialize SoEvent and all its known subclasses (i.e. all subclasses which are part of the standard classes in the Coin library). This method is called from SoDB::init(), so it is very unlikely that you will have to call it explicitly. SbBool SoEvent::isOfType (SoType type) const Returns TRUE if this object either has the same type as the given type parameter, or if type belongs to a superclass of ourselves. void SoEvent::setTime (const SbTime t) From a system specific device object, set the time the event occurred. See also getTime() SbTime SoEvent::getTime (void ) const Returns the time the event occurred. See also getPosition(), wasShiftDown(), wasCtrlDown(), wasAltDown() void SoEvent::setPosition (const SbVec2s & p) From a system specific device object, set the mouse pointer position when the event occurred. See also getPosition(), getNormalizedPosition() const SbVec2s & SoEvent::getPosition (void ) const Returns the mouse pointer position when the event occurred. The coordinates are given relative to the window coordinates. See also getNormalizedPosition(), getTime(), wasShiftDown(), wasCtrlDown(), wasAltDown() const SbVec2s & SoEvent::getPosition (const SbViewportRegion & vpRgn) const Returns the mouse pointer position when the event occurred. The coordinates are given relative to the viewport coordinates. See also getNormalizedPosition(), getTime(), wasShiftDown(), wasCtrlDown(), wasAltDown() const SbVec2f & SoEvent::getNormalizedPosition (const SbViewportRegion & vpRgn) const Returns the mouse pointer position when the event occurred. The coordinates are given relative to the viewport coordinates, normalized according to the size of the viewport. See also getPosition(), getTime(), wasShiftDown(), wasCtrlDown(), wasAltDown() void SoEvent::setShiftDown (SbBool isDown) From a system specific device object, set the state of the Shift key(s) when the event occurred. See also wasShiftDown(), setCtrlDown(), setAltDown() SbBool SoEvent::wasShiftDown (void ) const Returns state of Shift key(s) when the event occurred. See also wasCtrlDown(), wasAltDown(), getPosition(), getTime() void SoEvent::setCtrlDown (SbBool isDown) From a system specific device object, set the state of the Ctrl key(s) when the event occurred. See also wasCtrlDown(), setShiftDown(), setAltDown() SbBool SoEvent::wasCtrlDown (void ) const Returns state of Ctrl key(s) when the event occurred. See also wasShiftDown(), wasAltDown(), getPosition(), getTime() void SoEvent::setAltDown (SbBool isDown) From a system specific device object, set the state of the Alt key(s) when the event occurred. See also wasAltDown(), setCtrlDown(), setShiftDown() SbBool SoEvent::wasAltDown (void ) const Returns state of Alt key(s) when the event occurred.
