## Detailed Description

Register and deregister plug-in services with Maya.

This class is used in the initializePlugin and uninitializePlugin functions of a Maya plug-in to respectively register and deregister the plug-in's services (commands, node types, etc) with Maya. The constructor for this class must be passed the MObject that Maya provides as an argument to initializePlugin and uninitializePlugin.

MFnPlugin provides various registration methods for use inside initializePlugin, when the plug-in is being loaded, and deregistration methods for use inside uninitializePlugin, when the plug-in is being unloaded. In general it is good practice to have uninitializePlugin deregister the plug-in's services in the reverse order in which they were registered in initializePlugin. This ensures, for example, that a custom datatype is not deregistered before the node types which use it.

A plug-in's uninitializePlugin function is only called when the plug-in is explicitly unloaded. It is not called when Maya exits. Normally this is not a problem because system resources such as memory and open file handles are automatically released by the operating system when Maya exits. However, if there are cleanup tasks which a plug-in must perform even when Maya exits, for example deleting a temporary file, then the plug-in's initializePlugin can use the MSceneMessage::addCallback method with a message of "kMayaExiting" to register a callback function that will be executed when Maya is about to exit. The callback function can then handle any cleanup activities which the operating system won't handle automatically on exit.

A side effect of including MFnPlugin.h in a source file is to embed an API version string into the corresponding compiled object file. Because of this, including MFnPlugin.h in more than one source file in the same plug-in will lead to conflicts when the plug-in is linked. If it is necessary to include MFnPlugin.h in more than one of a plug-in's source files the preprocessor macro MNoVersionString should be defined in all but one of those files prior to the inclusion of MFnPlugin.h. Normally, this issue will not arise as only the file that contains the initializePlugin and uninitializePlugin routines should need to include MFnPlugin.h.

It is unusual, but possible, to instantiate several MFnPlugin objects within a single plug-in binary. In this case the vendor and version information that is set for the plug-in is taken from the first instance as this information works per binary rather than per command/node etc.

Register a new dependency node with Maya.

Once registered, the node can be used from MEL in a manner identical to built-in Maya nodes.

Parameters:

  [in] | typeName | the name of the new type of node
  [in] | typeId | a unique id that identifies this node
  [in] | creatorFunction | a pointer to a function that will return a pointer to a new instance of the class (derived from MPxNode) that implements the new node type
  [in] | initFunction | a pointer to a function that will initialize all the attributes of the new node type
  [in] | type | the type of plugin node to be registered
  [in] | classification | a string that determines how the node will be categorized in various rendering-related UI, such as the Create Render Node and HyperShade windows. See the documentation for the getClassification command for a list of the supported classifications. If no string is supplied then the node will not be considered a rendering node and will not be displayed in those UI. The classification also allows the node type to be recognized as a shape with Viewport 2.0. A classification string which starts with "drawdb/geometry" (plus any further subclassifications) is required. Note that adding the subclassification "transform" immediately after "geometry" will indicate that this is a transform instead of shape. See the documentation for registerTransform().

Returns:
  Status code

Status Codes:
  - MS::kSuccess if the node type was successfully registered
  - MS::kFailure the registration failed.
  - MS::kObjectDoesNotExist if the function set is not attached to an MObject.

Examples:
  blindDataPluginMain.cpp, hlslPluginMain.cpp, latticeNoise.cpp, meshOpMain.cpp, particleAttrNodeMain.cpp, pointOnMeshInfoPlugin.cpp, slopeShader.cpp, and splitUVMain.cpp.

MStatus deregisterNode | ( | const MTypeId & | typeId | ) |

Search for all occurrences

Deregister the given user defined dependency node type Maya.

Once deregistered new instances of the user defined dependency node can no longer be created. Additionally, any existing instances of the node type will be changed to the special type Unknown and will no longer evaluate in the dependency graph although they will be saved correctly if the scene is written.

Parameters:

  [in] | typeId | the unique type id of the node type to deregister

Returns:
  Status code

Status Codes:
  - MS::kSuccess if successful
  - MS::kFailure the node type was not owned by this plug-in
  - MS::kObjectDoesNotExist if the function set is not attached to an MObject.

Examples:
  latticeNoise.cpp.

  [in] | classification | a string that determines how the node will be categorized in various rendering-related UI, such as the Create Render Node and HyperShade windows. See the documentation for the getClassification command for a list of the supported classifications.

MStatus deregisterData | ( | const MTypeId & | typeId | ) |

Search for all occurrences

Deregister the given user defined data type from Maya.

It is important to note that this method will always fail if there are any instances of the user-defined data in the scene.

  [in] | typeId | the unique type id of the data type to deregister

Returns:
  Status code

Status Codes:
  - MS::kSuccess if successful
  - MS::kFailure the data type is being used by current instances of nodes in the dependency graph
  - MS::kObjectDoesNotExist if the function set is not attached to an MObject.

MStatus registerUIStrings | ( | MInitializeFunction | registerMStringResources,
|  | const MString & | pluginStringsProc
| ) |  |

Search for all occurrences

Set the callback and procedure names of routines that register plugin string resources and optionally load localized values for them.

These procedures are called immediately upon plugin load. They are responsible for registering all string resources that can be referred to during the plugin execution. If the string resources are localized, the localized values are also loaded at this time.

Each string resource is given a default value when it is registered. If the plugin is localized, any localized values specified will override the registered default and will be used instead of the default value when the resource value is queried.

The registerMStringResources callback is a function which makes a series of calls to MStringResource::registerString for each MStringResourceId to be registered. Its signature is described by the MInitializeFunction typedef.

The pluginStringsProc is a mel procedure that will be evaluated to register any other strings resources for the plugin, i.e. those used in the plugin's scripts (see the registerPluginString command). It is also responsible for loading the localized resource overrides if they are available (see loadPluginLanguageResources).

See also the following classes: MStringResourceId, MStringResource.

Parameters:

  [in] | registerMStringResources | This callback is used to register MStringResources that are used by the plugin code. The callback signature type is defined by MInitializeFunction.
  [in] | pluginStringsProc | The name of the mel procedure to be run during plugin load to register script-based resources. This script will also make the necessary calls to load localized string values if they exist.

Returns:
  Status code

Status Codes:
  - MS::kSuccess if successful
  - MS::kObjectDoesNotExist if the function set is not attached to an MObject.

NO SCRIPT SUPPORT.

Sets the names of the mel procedures to be evaled to create and destroy any UI associated with the plugin.

You can use MEL procedure names as arguments to this method as long as the procedure is located in a file named procedure.mel. This works because, as described in the MEL documentation, when MEL is given a undefined procedure, it searchs MAYA_SCRIPT_PATH looking for a file with the name procedure.mel. If it finds such a file it is sourced and if the procedure was defined by the file, it is then executed.

Example: The procedure lassoToolCreateUI will be run when the plugin is loaded, the procedure lassoToolDeleteUI when the plugin is unloaded. This works as long as the MEL procedure lassoToolCreateUI is defined in a file called lassoToolCreateUI.mel and the procedure lassoToolDeleteUI is defined in a file called lassoToolDeleteUI.mel.
