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.

Member Function Documentation

virtual const char* vtkCallbackCommand::GetClassName ( ) [virtual]

Reimplemented from vtkCommand.

static int vtkCallbackCommand::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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 vtkCommand.

virtual int vtkCallbackCommand::IsA ( const char * name ) [virtual]

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 vtkCommand.

static vtkCallbackCommand* vtkCallbackCommand::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkCommand.

static vtkCallbackCommand* vtkCallbackCommand::New ( ) [inline, static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObjectBase.

Definition at line 53 of file vtkCallbackCommand.h.

virtual void vtkCallbackCommand::Execute	(	vtkObject *	caller,
		unsigned long	eid,
		void *	callData
	)		`[virtual]`

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.

virtual void vtkCallbackCommand::SetClientData ( void * cd ) [inline, virtual]

Methods to set and get client and callback information, and the callback function.

virtual void* vtkCallbackCommand::GetClientData ( ) [inline, virtual]

Methods to set and get client and callback information, and the callback function.

Definition at line 67 of file vtkCallbackCommand.h.

virtual void vtkCallbackCommand::SetCallback ( void(*)(vtkObject *caller, unsigned long eid, void *clientdata, void *calldata) f ) [inline, virtual]

Methods to set and get client and callback information, and the callback function.

virtual void vtkCallbackCommand::SetClientDataDeleteCallback ( void(*)(void *) f ) [inline, virtual]

Methods to set and get client and callback information, and the callback function.

Definition at line 72 of file vtkCallbackCommand.h.

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.

Definition at line 80 of file vtkCallbackCommand.h.

int vtkCallbackCommand::GetAbortFlagOnExecute ( ) [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.

Definition at line 82 of file vtkCallbackCommand.h.

void vtkCallbackCommand::AbortFlagOnExecuteOn ( ) [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.

Definition at line 84 of file vtkCallbackCommand.h.

void vtkCallbackCommand::AbortFlagOnExecuteOff ( ) [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.
