Public Member Functions

 ChangeContourObjectProfileAction ()
 Constructor for the action.
 ~ChangeContourObjectProfileAction ()
virtual ActionCode Execute ()
 Executes the action. This will reset the num blend steps in pThisNodeBlend to OldNumSteps, after creating another action to record the current num steps of pThisNodeBlend.

Static Public Member Functions

static ActionCode Init (Operation *pOp, ActionList *pActionList, NodeContourController *pThisNodeContour, CProfileBiasGain Profile, ChangeContourObjectProfileAction **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.
static void ChangeObjectProfileWithNoUndo (CProfileBiasGain &Profile)
 When applying contour (object) profiles, we only want to generate one bit of undo information. This function allows us to meet this requirement (the one bit of undo information is generated via OpChangeContourObjectProfile::DoWithParam ()). This function is ONLY called from within ContourInfoBarOp::ChangeProfile () - after OpChangeContourObjectProfile::DoWithParam () has been called.
