MFnKeyframeDeltaMove Class Reference

#include <MFnKeyframeDeltaMove.h>

Class Description

Function set for change in keyframe value or time.

This function set is used for keyframe deltas of type MFn::kKeyframeDeltaMove. These keyframe deltas are generated from 'move' events. For example, the user drags or scales a key from one position to another.

Constructor & Destructor Documentation

MFnKeyframeDeltaMove	(	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

MFnKeyframeDeltaMove	(	const 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

Member Function Documentation

MFn::Type type ( ) const

virtual

Function set type.

Return the class type : MFn::kKeyframeDeltaMove.

Reimplemented from MFnKeyframeDelta.

OPENMAYA_MAJOR_NAMESPACE_OPEN const char * className ( ) const

protectedvirtual

Class name.

Return the class name : "MFnKeyframeDeltaMove".

Reimplemented from MFnKeyframeDelta.

MTime previousTime

(

MStatus *

ReturnStatus = NULL

)

const

The previous time value of this key.

Parameters

[out]

ReturnStatus

Return Code

Returns

A MTime containing the previous time of this key.

Status Codes:

• MS::kSuccess The operation succeeded.
• MS::kFailure An object error has occurred.

MTime currentTime

(

MStatus *

ReturnStatus = NULL

)

const

The current/current time value.

Parameters

[out]

ReturnStatus

Status code.

Returns

A MTime containing the current time of this key.

Status Codes:

• MS::kSuccess The operation succeeded.
• MS::kFailure An object error has occurred.

double previousValue

(

MStatus *

ReturnStatus = NULL

)

const

The previous value of the key prior to the change.

The value corresponds to the units of the animation curve.

Parameters

[out]

ReturnStatus

Return code.

Returns

A double representing the previous value of the key.

Status Codes:

• MS::kSuccess The operation succeeded.
• MS::kFailure An object error has occurred.

double currentValue

(

MStatus *

ReturnStatus = NULL

)

const

The current value of the key.

The value corresponds to the units of the animation curve.

Parameters

[out]

ReturnStatus

Return code.

Returns

A double representing the current value of the key.

Status Codes:

• MS::kSuccess The operation succeeded.
• MS::kFailure An object error has occurred.

unsigned int previousIndex

(

MStatus *

ReturnStatus = NULL

)

const

The previous index value of this key.

If a key has been moved over another key then you can use this previous index to figure out where the key was moved from.

Parameters

[out]

ReturnStatus

Return code.

Returns

An unsigned value representing the previous index of this key on the curve.

Status Codes:

• MS::kSuccess The operation succeeded.
• MS::kFailure An object error has occurred.

unsigned int keyIndex ( MStatus *  ReturnStatus = NULL ) const

virtual

The current index value of this key.

Parameters

[out]

ReturnStatus

Return code.

Returns

An unsigned value representing the current index of this key on the curve.

Status Codes:

• MS::kSuccess The operation succeeded.
• MS::kFailure An object error has occurred.
