Detailed 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

Examples:

apiMeshShape.cpp, apiMeshShape.h, apiMeshShapeUI.cpp, apiSimpleShapeUI.cpp, and quadricShape.cpp.

#include <MSelectionMask.h>

Sets the selection mask to the specified selection type.

Parameters:
[in]selTypethe selection type to be set
Returns:
MStatus setMask ( MSelectionMask mask)

Sets the selection type for this mask to the selection type of the specified mask.

Parameters:
[in]maskthe mask with the selection type to be set
Returns:
MStatus addMask ( MSelectionMask::SelectionType  selType)

Add the specified selection type to this mask.

Parameters:
[in]selTypethe selection type to add
Returns:
bool intersects ( MSelectionMask::SelectionType  selType,
MStatus ReturnStatus = NULL 
) const

Returns true if the specified selection type is contained within this selection mask.

Parameters:
[in]selTypethe selection type to test
[out]ReturnStatusstatus code
Returns:
  • true the specified selection type is contained in this mask
  • false the specified selection type is not in this mask
Status Codes:
bool intersects ( MSelectionMask mask,
MStatus ReturnStatus = NULL 
) const

Returns true if the specified selection mask is contained within this selection mask.

[in]maskthe mask containing the selection type to add
Returns:
The new mask
MSelectionMask & operator= ( const MSelectionMask other)

[in]otherthe mask to be copied
Returns:
A reference to the copied 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.
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.
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.
