Public Member Functions

 RecordChangeCodesAction ()
 Constructor for the action to undo Perspective modification.
 ~RecordChangeCodesAction ()
 Destructor for the action to undo Perspective modification.
virtual ActionCode Execute ()
 This is the virtual function that is called when the action is executed by the Undo/Redo system.

Static Public Member Functions

static ActionCode Init (Operation *pOp, ActionList *pActionList, NodeMould *pMould, Action **NewAction)
 This is the function which creates an instance of this action. If there is no room in the undo buffer (which is determined by the base class Init function called within) the function will either return AC_NORECORD which means the operation can continue, but no undo information needs to be stored, or AC_OK which means the operation should continue AND record undo information. If the function returns AC_FAIL, there was not enough memory to record the undo information, and the user has decided not to continue with the operation.

ActionCode RecordChangeCodesAction::Init (  Operation *  pOp,
ActionList *  pActionList,
NodeMould *  pMould,
Action **  NewAction
)  [static]
 

This is the function which creates an instance of this action. If there is no room in the undo buffer (which is determined by the base class Init function called within) the function will either return AC_NORECORD which means the operation can continue, but no undo information needs to be stored, or AC_OK which means the operation should continue AND record undo information. If the function returns AC_FAIL, there was not enough memory to record the undo information, and the user has decided not to continue with the operation.

Parameters:
pOp = a pointer to the operation to which this action belongs [INPUTS] pActionList = is the action list to which this action should be added pMould = a pointer to a NodeMould object
NewAction = a pointer to a pointer to an action, allowing the function to [OUTPUTS] return a pointer to the created action.
Returns:
ActionCode, = AC_OK if the action was created correctly = AC_NORECORD if no memory to undo/redo but go ahead anyway without undo = AC_FAIL stop the operation
