void SMESH_subMeshEventListener::ProcessEvent	(	const int	event,
		const int	eventType,
		SMESH_subMesh *	subMesh,
		SMESH_subMeshEventListenerData *	data,
		const SMESH_Hypothesis *	hyp = 0
	)		[virtual]

Do something on a certain event.

Parameters:

event	- algo_event or compute_event itself (of SMESH_subMesh)
eventType	- ALGO_EVENT or COMPUTE_EVENT (of SMESH_subMesh)
subMesh	- the submesh where the event occures
data	- listener data stored in the subMesh
hyp	- hypothesis, if eventType is algo_event

The base implementation (see SMESH_subMesh.cxx) translates CLEAN event to the subMesh stored in the listener data. Also it sends SUBMESH_COMPUTED event in case of successful COMPUTE event.

Parameters:

event	- algo_event or compute_event itself
eventType	- algo_event or compute_event
subMesh	- the submesh where the event occures
data	- listener data stored in the subMesh
hyp	- hypothesis, if eventType is algo_event

The base implementation translates CLEAN event to the subMesh stored in listener data. Also it sends SUBMESH_COMPUTED event in case of successful COMPUTE event.

Reimplemented in VISCOUS._SrinkShapeListener, and VISCOUS._ViscousListener.
