Detailed Description

Double indexed component function set.

This function set allows you to create, edit, and query double indexed components. Double indexed components store 2 dimensional index values.

Examples:: customComponentTagNode/customComponentTagNode.cpp, listRichSelectionCmd/listRichSelectionCmd.cpp, and paintCallback/paintCallback.cpp.

Constructor & Destructor Documentation

MFnDoubleIndexedComponent	(	MObject &	object,
		MStatus *	ReturnStatus = `NULL`
	)

Constructor.

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

Parameters

[in]	object	The MObject to attach the function set to
[out]	ReturnStatus	the 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

MFnDoubleIndexedComponent	(	const MObject &	object,
		MStatus *	ReturnStatus = `NULL`
	)

NO SCRIPT SUPPORT.

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

Constructor

Parameters

[in]	object	The MObject to attach the function set to
[out]	ReturnStatus	the 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

Member Function Documentation

MFn::Type type ( ) const

Return the class type : MFn::kDoubleIndexedComponent.

Returns: the class type.

Reimplemented from MFnComponent.

OPENMAYA_MAJOR_NAMESPACE_OPEN const char * className ( )

static

Returns the name of this class.

Return the class name : "MFnDoubleIndexedComponent".

Returns: Name of this class.

MObject create	(	MFn::Type	compType,
		MStatus *	ReturnStatus = `NULL`
	)

Create a double indexed component of the given type.

Allowable types are

MFn::kSurfaceCVComponent MFn::kSurfaceEPComponent MFn::kSurfaceKnotComponent MFn::kMeshVtxFaceComponent

Parameters

[in]	compType	the type of component to create
[out]	ReturnStatus	status code

Returns: The new component

Status Codes:

MS::kSuccess the method was successful.
MS::kInvalidParameter invalid component type

Examples:: customComponentTagNode/customComponentTagNode.cpp.

MStatus addElement	(	int	uIndex,
		int	vIndex
	)

Add the specified element to the component.

Parameters

[in]	uIndex	the u index to add
[in]	vIndex	the v index to add

Returns: Status code

Status Codes:

MS::kSuccess the method was successful
MS::kFailure an object error has occurred

Examples:: customComponentTagNode/customComponentTagNode.cpp.

MStatus addElements	(	const MIntArray &	uIndices,
		const MIntArray &	vIndices
	)

Add the specified elements to the component.

Parameters

[in]	uIndices	the array of u indices to be added
[in]	vIndices	the array of v indices to be added

Returns: Status code

Status Codes:

MS::kSuccess the method was successful
MS::kFailure an object error has occurred

MStatus getElement	(	int	index,
		int &	uIndex,
		int &	vIndex
	)		const

Get the specified element from the component.

Parameters

[in]	index	the index of the element to retrieve
[out]	uIndex	the u index of the component
[out]	vIndex	the v index of the component

Returns: Status code

Status Codes:

MS::kSuccess the method was successful

Examples:: paintCallback/paintCallback.cpp.

MStatus setCompleteData	(	int	maxU,
		int	maxV
	)

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]	maxU	the maximum number of U elements
[in]	maxV	the maximum number of V elements

Returns: Status code

Status Codes:

MS::kSuccess the method was successful
MS::kFailure an object error has occurred

MStatus getCompleteData	(	int &	maxU,
		int &	maxV
	)		const

Returns the number of elements for the complete component.

A complete component means that all elements are selected.

Parameters

[out]	maxU	storage for the maximum number of U elements
[out]	maxV	storage for the maximum number of V elements

Returns: Status code

Status Codes:

MS::kSuccess the method was successful
MS::kFailure an object error has occurred
