Public Member Functions

 InitBlendersAction ()
 Constructor for the action.
 ~InitBlendersAction ()
virtual ActionCode Execute ()
 Executes the action. This remaps the blend node using the inverse mapping indexes it was initialised with, creating another InitBlendersAction to invert this mapping.

Static Public Member Functions

static ActionCode Init (OpBlendNodes *pOp, ActionList *pActionList, List *pBlenderInfoList, BOOL DeinitState, InitBlendersAction **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_NO_RECORD 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 = ptr to the operation to which this action belongs [INPUTS] pActionList = ptr to action list to which this action should be added pBlenderInfoList= ptr to a NodeBlend Deinit = TRUE if deinit blend, else reinit
ppNewAction = ptr to a ptr to an action, allowing the function to return [OUTPUTS] a pointer to the created action
Returns:
ActionCode, one of AC_OK, AC_NO_RECORD or AC_FAIL
If Deinit == TRUE, then undo will reinit the blenders and redo will deinit them again. The reverse happens if Deinit == FALSE;
