Public Member Functions

 ChangeBrushDefAction ()
 Constructor for the action.
 ~ChangeBrushDefAction ()
 destructor for the action
virtual ActionCode Execute ()
 Executes the action. This will reset the brush variables to their old values.

Static Public Member Functions

static ActionCode Init (Operation *pOp, ActionList *pActionList, ChangeBrushDefOpParam *pChangeParam, ChangeBrushDefAction **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.

ActionCode ChangeBrushDefAction::Init (  Operation *  pOp,
ActionList *  pActionList,
ChangeBrushDefOpParam *  pChangeParam,
ChangeBrushDefAction **  ppNewAction
)  [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_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.

Date:

Parameters:
pOp = ptr to the operation to which this action belongs [INPUTS] pActionList = ptr to action list to which this action should be added pBrushedNode = ptr to node with brush attribute to change pChangeParam = ptr to class that details how the blend should be changed.
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
This function actually changes the blend node in a way specified in pChangeParam
Returns:
