Public Member Functions

 ChangeFillProfileAction ()
 Construct an object of this type.
 ~ChangeFillProfileAction ()
 Destruct an object of this type.
virtual ActionCode Execute ()
 Executes the action. This will reset the fill profile in m_pNodeFill to its previous one, after creating another action to record the current fill profile of m_pNodeFill in.

Static Public Member Functions

static ActionCode Init (Operation *pOp, ActionList *pActionList, AttrFillGeometry *pThisNodeFill, CProfileBiasGain &Profile, ChangeFillProfileAction **NewAction, BOOL bReverse=TRUE, BOOL bCache=FALSE)
 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 ChangeFillProfileWithNoUndo (CProfileBiasGain &Profile)
 When applying fill 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 OpChangeFillProfile::DoWithParam ()). This function is ONLY called from within GradInfoBarOp::ChangeProfile () - after OpChangeFillProfile::DoWithParam () has been called.
