## Detailed 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.

`#include <MFnKeyframeDeltaMove.h>`

## 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

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

Search for all occurrences

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]`

Search for all occurrences

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.
