Detailed Description

supports function callbacks

Use vtkCallbackCommand for generic function callbacks. That is, this class can be used when you wish to execute a function (of the signature described below) using the Command/Observer design pattern in VTK. The callback function should have the form

void func(vtkObject*, unsigned long eid, void* clientdata, void *calldata)

where the parameter vtkObject* is the object invoking the event; eid is the event id (see vtkCommand.h); clientdata is special data that should is associated with this instance of vtkCallbackCommand; and calldata is data that the vtkObject::InvokeEvent() may send with the callback. For example, the invocation of the ProgressEvent sends along the progress value as calldata.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

void vtkCallbackCommand::Execute	(	vtkObject *	caller,
		unsigned long	eid,
		void *	callData
	)

overridevirtual

Satisfy the superclass API for callbacks.

Recall that the caller is the instance invoking the event; eid is the event id (see vtkCommand.h); and calldata is information sent when the callback was invoked (e.g., progress value in the vtkCommand::ProgressEvent).

Implements vtkCommand.

void vtkCallbackCommand::SetAbortFlagOnExecute ( int f )

inline

Set/Get the abort flag on execute.

If this is set to true the AbortFlag will be set to On automatically when the Execute method is triggered and a callback is set.
