void *clientData
);
Parameters
interactionContext
Handle to the Interaction Context.

Remarks
Provides enhanced gesture recognition support compared to INTERACTION_CONTEXT_OUTPUT_CALLBACK callback function.
Each instance of an Interaction Context is limited to one output callback. Registering a callback function overwrites any existing callback registration for the Interaction Context.
This function is typically called after the creation of an Interaction Context or when the Interaction Context is reassigned to another UI element.
