Public Member Functions

 ChangeBlenderAction ()
 Constructor for the action.
 ~ChangeBlenderAction ()
virtual ActionCode Execute ()
 Executes the action.

Static Public Member Functions

static ActionCode Init (Operation *pOp, ActionList *pActionList, NodeBlender *pNodeBlender, ChangeBlenderOpParam &ChangeParam)
 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.
