Detailed Description

Constructor & Destructor Documentation

MFnSingleIndexedComponent ( MObject object,
MStatus ReturnStatus = NULL 
)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters
[in]objectThe MObject to attach the function set to
[out]ReturnStatusthe return status
Status Codes:
  • MS::kSuccess if the function set is successfully attached
  • MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject
MFnSingleIndexedComponent ( const MObject object,
MStatus ReturnStatus = NULL 
)

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters
[in]objectThe MObject to attach the function set to
[out]ReturnStatusthe return status
Status Codes:
  • MS::kSuccess if the function set is successfully attached
  • MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MStatus setCompleteData ( int  numElements)

Marks the component as complete (meaning all items are selected) and uses the argument to identify the total number of elements selected.

If the component should contain N element indices, then the range would be [0,N-1].

Also sets the complete state of the component to 'true' (i.e. setComplete(true)).

Parameters
[in]numElementsthe maximum number of elements in the component

MStatus getCompleteData ( int &  numElements) const

Returns the number of elements for the complete component.

A complete component means that all elements are selected.

Parameters
[out]numElementsstorage for the maximum number of elements
Returns
Status code
Status Codes:
  • MS::kSuccess the method was successful
  • MS::kFailure an object error has occurred
