Detailed Description

Dependency node messages.

This class is used to register callbacks for dependency node messages of specific dependency nodes.

There are 2 add callback methods which will add callbacks for the following messages

  • Begin Camera Manipulation
  • End Camera Manipulation

Camera manipulation is triggered by:

  • Dolly
  • Orbit
  • PanZoom
  • Roll
  • Track
  • Tumble

The first parameter passed to each of the add callback methods is the cameraShape node that will trigger the callback.

Each method returns an id which is used to remove the callback.

To remove a callback use MMessage::removeCallback. All callbacks that are registered by a plug-in must be removed by that plug-in when it is unloaded. Failure to do so will result in a fatal error.

Member Function Documentation

MCallbackId addBeginManipulationCallback ( const MObject node,
MMessage::MNodeFunction  func,
void *  clientData = NULL,
MStatus ReturnStatus = NULL 
)
static

Registers callbacks for camera manipulation beginning messages.

Parameters
[in]nodethe set to register the callback for
[in]functhe callback function
  • node the cameraShape that has triggered a beginManipulation event
  • clientData User defined data passed to the callback function
Parameters
[in]clientDataUser defined data that will be passed to the callback function
[out]ReturnStatusstatus code
Returns
Identifier used for removing the callback.
Status Codes:
  • MS::kSuccess Operation succeeded
  • MS::kInsufficientMemory No memory available
  • MS::kFailure Error adding callback
Examples:
cameraMessageCmd/cameraMessageCmd.cpp.
MCallbackId addEndManipulationCallback ( const MObject node,

void *  clientData = NULL,
MStatus ReturnStatus = NULL 
)
static

Registers callbacks for camera manipulation ending messages.

Parameters
[in]nodethe set to register the callback for
[in]functhe callback function
