Detailed Description

Static class providing common API global functions.

Provide methods for selection, 3D-views, time, model manipulation and MEL commands.

MGlobal is a static class which provides access to Maya's model (3d graphical database).

MGlobal provides methods for selection, 3d-views, setting the global time, adding to the DAG, and executing MEL commands from within the API. There are multiple methods provided in this class for executing MEL within the API. Plug-ins requiring the execution of MEL from the non-main Maya thread must use the executeCommandOnIdle() method to avoid program errors.

MGlobal also provides methods for controlling error logging in the API.

Examples:
apiMeshShape/apiMeshGeometryOverride.cpp, apiMeshShape/apiMeshSubSceneOverride.cpp, and hwApiTextureTest/hwRendererHelperDX.cpp.

int apiVersion ( )
static

Returns a number describing the version of the Maya API at runtime.

Returns
The current API version
bool isCustomVersion ( )
static

Returns true if this is a custom version of Maya.

Returns
A boolean indicating whether this is a custom version of Maya

int customVersion ( )
static

Returns an encoded number describing the custom version of Maya at runtime.

This number can be used to compare custom versions of Maya and is encoded as (10000 * maya_major_version + 100 * custom_major_version + custom_minor_version). Note: If this is not a custom version then (10000 * maya_major_version) will be returned.

An encoded number describing the custom version of Maya.
MString getAbsolutePathToResources ( )
static

Return the absolute path of Maya's "Resources" fold on the system, including the "Resources" folder itself.

Returns
An MString object containing the absolute path to the "Resources" folder
bool isDefaultLanguage ( )
static

Returns True when no specific localization has been requested, or the localization requested was not supported or installed.

Returns
Returns true if the current UI language is the default (en_US).
MString getUILanguage ( )
static

Return standardized string identifier representing the UI language to use.

This will either be a localized language, or the default language.

MGlobal::MMayaState mayaState ( MStatus ReturnStatus = NULL)
static

Returns an enumerated type specifying the way in which Maya was invoked.

Parameters
[out]ReturnStatusStatus code.
Returns
Status Codes:
  • MS::kSuccess Method was successful
  • MS::kFailure Object error
Examples:
autoLoader/autoLoader.cpp, cgFx/cgfxShaderCmd.cpp, cgFx/pluginMain.cpp, dx11Shader/dx11Shader.cpp, dx11Shader/dx11ShaderPluginMain.cpp, glslShader/GLSLShader.cpp, glslShader/GLSLShaderMainMaya.cpp, gpuCache/gpuCacheCmd.cpp, gpuCache/gpuCachePluginMain.cpp, gpuCache/gpuCacheShapeNode.cpp, gpuCache/gpuCacheVramQuery.cpp, hlslShader/hlslPluginMain.cpp, and sceneAssembly/sceneAssemblyPluginMain.cpp.
MStatus getFunctionSetList ( MObject  forObject,
MStringArray array 
)
static

Gets a list of strings that represent the type of each function set that will accept this object.

The strings match the values in MFn.h.

Parameters
[in]forObjectobject to get list of function sets for
[out]arraystorage for the array of strings
Returns
Status Code
Status Codes:
  • MS::kSuccess Selection was successful
Examples:
whatisCmd/whatisCmd.cpp.
MStatus getAssociatedSets ( const MSelectionList list,
MObjectArray setArray 
)
static

This utility method finds all the sets that the items in the given selection list are members of.

Parameters
[in]listitems to finds sets for
[out]setArraystorage for the array of sets
Returns
Status Code
Status Codes:
  • MS::kSuccess Selection was successful
  • MS::kFailure An error occurred while getting the sets
MStatus getSelectionListByName ( const MString name,
MSelectionList list 
)
static

This method fills a selection list with all of the objects that match a specified name.

The name may use the same type of regular expressions the can be used in MEL commands. For example, the pattern "pCube*" will match all occurances of objects that begin their names with "pCube".

Taking this a step further, the following example looks for all objects that both start their names with "pCube" but also have a child that starts its name with "pCubeShape". Since the pattern is matching a DAG path, the items that match the pattern should be DAG nodes.

MStatus testCommand::doIt()
{
MString toMatch ("pCube*|pCubeShape*");
unsigned int ii = 0;
unsigned int nMatches = sList.length();
for (ii = 0; ii < nMatches; ++ii) {
sList.getDagPath(ii, dp);
cout << dp.fullPathName() << endl;
}
return MS::kSuccess ;
}

For the case where a polyCube (pCube1) is the parent of another polyCube (pCube2), the output of the above example would be as follows:

|pCube1|pCubeShape1 |pCube1|pCube2|pCubeShape2

Parameters
[in]nameRegular expression to match object name.
[out]listSelection list into which the objects matching the name will be placed.
Returns
Status code
Status Codes:
  • MS::kSuccess Objects matching the name were successfully found
  • MS::kFailure Error getting the objects.
Examples:
ik2Bsolver/ik2Bsolver.cpp.
MStatus getActiveSelectionList ( MSelectionList dest,
bool  orderedSelectionIfAvailable = false 
)
static

Returns a copy of the active selection list, or optionally a copy of the ordered active selection list.

This is the active selection list but with components as well as objects appearing in the order that they were selected.

In order to get the ordered selection list, tracking component selection order must be enabled through either the 'selectPref' Maya command or through the MGlobal function 'setTrackSelectionOrderEnabled'.

Parameters
[out]destStorage for the selection list
[in]orderedSelectionIfAvailableIf true, and tracking is enabled, will return the selected items in the order that they were selected.
Returns
Status code
Status Codes:
  • MS::kSuccess Active selection list was successfully returned
  • MS::kFailure Error getting the active selection list

MStatus addToModel ( MObject object,

This method is used to add new dag objects to the model.

If no parent node is specified, then the node is added under the world. When a node is added under the world, then a transform node is automatically created as a parent. This assumes that the node being added is not already a transform node. This method is only valid for dag nodes. If the specified object is not of type MFn::kDagNode then MS::kInvalidParameter will be returned.

Parameters
[in]objectobject to be added
[in]parentparent dag node (optional)
Returns
Status Code
Status Codes:
  • MS::kSuccess Object was successfully added
  • MS::kInvalidParameter Object or parent is invalid or object is already in the model
  • MS::kFailure Could not add object to model
MStatus addToModelAt ( MObject object,
const MVector point,

Adds the specified dag object to the DAG and transform the object by the specified arguments.

This method is only valid for dag nodes. If the specified object is not of type MFn::kDagNode then MS::kInvalidParameter will be returned.

Parameters
[in]objectthe object to be added to the DAG
[in]pointtranslation vector
[in]scalescale amount
[in]rotationrotation amount
[in]rotOrderthe order of the rotation
Returns
Status Code
Status Codes:

MStatus removeFromModel ( MObject object)
static

Removes the specified dag node from the scene.

This method is only valid for dag nodes. If the specified object is not of type MFn::kDagNode then MS::kInvalidParameter will be returned.

Note that this method doesn't delete the dag node which means the node must be added back to scene by calling either MGlobal::addToModel() or MGlobal::addToModelAt() in later calls, otherwise the dag node is leaked. To delete the dag node, call MGlobal::deleteNode() instead.

Parameters
[in]objectdag node to be removed from the scene
Returns
Status Code
Status Codes:
  • MS::kSuccess node was successfully removed
  • MS::kInvalidParamter object is NULL, or is not a dag node, or has already been removed

Returns
Status Code
Status Codes:
  • MS::kSuccess Output to API error log is enabled
  • MS::kFailure Could not enable output to API error log - could not access error log handler or could not start log.

  • MS::kFailure Status of log unknown - could not access error log handler
MStatus closeErrorLog ( )
static

This method closes the API error log file.

If error logging is currently enabled this method disables it. The error log is time and date stamped before it is closed. After the log is closed the error log path name is reset to the default path name. If the error log file is already closed, then no action is taken.

Note that if a log is reopened after it is closed, all information previously logged to it is lost.

Returns
