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 scenegraph through an SoHandleEventAction.
Events may be caught by the user by attaching an SoEventCallback node to the scenegraph, or it can automatically be handled by a dragger or manipulator in the graph.
|
Constructor, will set all modifiers to "off" state. |
|
Destructor. |
|
Returns TRUE if this object either has the same type as the given |
|
This static method returns the SoType object associated with objects of this class. |
|
Returns the actual type id of an instantiated object. |
|
From a system specific device object, set the time the event occurred.
|
|
Returns the time the event occurred.
|
|
From a system specific device object, set the mouse pointer position when the event occurred.
|
|
Returns the mouse pointer position when the event occurred. The coordinates are given relative to the window coordinates.
|
|
Returns the mouse pointer position when the event occurred. The coordinates are given relative to the viewport coordinates.
|
|
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.
|
|
From a system specific device object, set the state of the Shift key(s) when the event occurred.
|
|
Returns state of Shift key(s) when the event occurred.
|
|
From a system specific device object, set the state of the Ctrl key(s) when the event occurred.
|
|
Returns state of Ctrl key(s) when the event occurred.
|
|
From a system specific device object, set the state of the Alt key(s) when the event occurred.
|
|
Returns state of Alt key(s) when the event occurred.
|

Initialize SoEvent and all it's 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's very unlikely that you will have to call it explicitly. Reimplemented in SoButtonEvent, SoKeyboardEvent, SoLocation2Event, SoMotion3Event, SoMouseButtonEvent, and SoSpaceballButtonEvent. |
