Typedef Documentation

typedef void(* xn::StateChangedHandler)(ProductionNode &node, void *pCookie)

Type definition to define event handlers for the 'State Change' event.

Parameters:
[in]nodeNode issuing the event.
[in]pCookieUser cookie passed on registration.

Remarks

The 'State Change' event can be invoked by a number of OpenNI objects. For example, this event is invoked by the ErrorStateCapability object whenever a node's error state changes. As another example, this event is also invoked by the MirrorCapability object whenever a node's mirror configuration has been changed.

Example:

The following is an example of a callback method that follows that signature:

    void XN_CALLBACK_TYPE OnEvent(ProductionNode& node, void* pCookie)
    {
    }
