Class Description

Manage what is selectable in Maya. (OpenMaya) (OpenMaya.py)

Selection masks provide a way to control what is selectable in Maya.

Selection masks can be created by OR'ing several types together, or by using the addMask method to add a selection type to an MSelectionMask.

Example - to set the object selection mask to nurbsSurfaces, nurbsCurves, cameras, and lights

MSelectionMask mask( MSelectionMask::kSelectNurbsSurfaces );
mask.addMask( MSelectionMask::kSelectNurbsCurves );
mask = mask | MSelectionMask::kSelectCameras | MSelectionMask::kSelectLights;
MGlobal::setObjectSelectionMask( mask );

bool registerSelectionType ( const MString &  selTypeName,
int  priority = 0 
)
static

Registers a new selection type.

It is perfectly legal for 2 plug-ins to register the same selection type. Currently we use the registration count. The selection type is deleted only when deregisterSelectionType() as been called the same number of times as this function - registerSelectionType().

When registerSelectionType() is invoked and the selection type already exists,we neither enable it nor change its priority, just add its registration count by 1. The reason is the user might has modified these values after loading the plug-in that has register the selection type the first time.

Parameters
[in]selTypeNameName of the selection type.
[in]priorityPriority of the selection type,see 'selectPriority' command.
Returns
  • true The selection type was successfully registered.
  • false Failed to register the selection type.
+ Examples:
bool deregisterSelectionType ( const MString &  selTypeName)
static

Unregisters a previously registered selection type.

Parameters
[in]selTypeNameName of the selection type.
Returns
  • true The selection type was successfully unregistered.
  • false Failed to unregister the selection type.
+ Examples:
int getSelectionTypePriority ( const MString &  selTypeName)
static

Gets the selection priority corresponding to a given selection type.

Parameters
[in]selTypeNameName of the selection type.
Returns
The selection priority corresponding to a given selection type. return -1 if there is no select type named selTypeName.
