Detailed Description

Base class for user defined manipulator containers.

MPxManipContainer is the base class for user-defined container manipulators. This class is derived from MPxNode since manipulators in Maya are dependency nodes.

MPxManipContainer is a container manipulator that has at least one base manipulator. MPxManipContainer has methods for adding the following base manipulators types to the container: FreePointTriadManip, DirectionManip, DistanceManip, PointOnCurveManip, PointOnSurfaceManip, DiscManip, CircleSweepManip, ToggleManip, StateManip, and CurveSegmentManip.

A container manipulator has one converter which is the interface between the container's children manipulators and the node plugs they affect. The values on the converter that are related to children manipulators are called converterManipValues, and the values on the converter that are related to the node plugs are called converterPlugValues.

The conversion between converterManipValues and converterPlugValues are performed through conversion callback methods, except when there is a one-to-one connection between a converterManipValue and a converterPlugValue.

There are two kinds of conversion callback methods: manipToPlug and plugToManip. A plugToManipConversionCallback is used to calculate a converterManipValue from various converterPlugValues. This callback has access to all the converterPlugValues and returns the value of a converterManipValue. A manipToPlugConversionCallback is used to calculate a converterPlugValue from various converterManipValues. This callback has access to all the converterManipValues and returns the value of a converterPlugValue.

In order for an MPxManipContainer to be able to run, the manipulator needs to know that the initialization is finished through the finishAddingManips method.

Examples:

componentScaleManip.cpp, customAttrManip.cpp, footPrintManip.cpp, lineManipContainer.h, moveManip.cpp, rotateManip.cpp, surfaceBumpManip.cpp, and swissArmyManip.cpp.

MPxNode::Type MPxManipContainer::type (  )  const [virtual]

This method returns the type of the node.

Returns:
MPxNode::kManipContainer

Reimplemented from MPxNode.

MStatus MPxManipContainer::initialize (  )  [static]

This method initializes the manipulator, and should be overriden in user-defined manipulators.

Returns:
Status of the operation. The base class always returns MS::kSuccess.
Examples:

MPxManipContainer * MPxManipContainer::newManipulator ( const MString manipName,
MObject manipObject,
MStatus ReturnStatus = NULL 
) [static]

This static function is used to create a user-defined manipulator. The manipObject argument is set to the new manipulator node. Note that the manipName argument must be the name of a manipulator derived from MPxManipContainer. Also note that this method creates the newManipulator, but doesn't add it to the DAG. The primary use of this method is in conjunction with MPxSelectionContext::addManipulator, to add user-defined manipulators to a context.

Parameters:
[in] manipName manipulator name
[in] manipObject manipulator object
Returns:
