Class 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 Viewport 2.0, all child manipulators will draw automatically. However for custom drawing (things done in the draw() method for the default viewport), the plugin must also implement preDrawUI() and drawUI(). Note that selection relies on the default viewport draw pass so the draw() method must still be implemented even if the manipulator is not intended for use in the default viewport.

preDrawUI() is called before drawUI() and should be used to prepare and cache data which will be needed to perform the custom drawing in drawUI().

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

MPxNode::Type type ( ) const

virtual

This method returns the type of the node.

Returns: MPxNode::kManipContainer

Reimplemented from MPxNode.

MStatus 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:: componentScaleManip/componentScaleManip.cpp, customAttrManip/customAttrManip.cpp, footPrintManip/footPrintManip.cpp, lineManipContainer/lineManipContainer.cpp, lineManipContainer/lineManipContainer.h, manipOverride/customTriadManip.cpp, manipOverride/customTriadManip.h, manipOverride/manipOverride.cpp, moveManip/moveManip.cpp, rotateManip/rotateManip.cpp, surfaceBumpManip/surfaceBumpManip.cpp, and swissArmyManip/swissArmyManip.cpp.

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
[out]	manipObject	manipulator object
[out]	ReturnStatus	Status code.

Returns: The new manipulator

void preDrawUI ( const M3dView & view )

virtual

This method is not available in Python.

This function is used to setup some drawing data for drawing the manipulator in Viewport 2.0 .

The data updated and cached in this function will be used later during 'drawUI()'.

This method is only called when the manipulator needs to be drawn in Viewport 2.0.

This method needs only be overridden if custom data is needed for drawing in drawUI(). If no such data is needed, this method may be left unimplemented.

This function is empty in this base class.

Parameters

[in] view the view in which to draw

Examples:: footPrintManip/footPrintManip.cpp, and swissArmyManip/swissArmyManip.cpp.

void drawUI	(	MHWRender::MUIDrawManager &	drawManager,
		const MHWRender::MFrameContext &	frameContext
	)		const

virtual

This method is not available in Python.

This is the primary method for doing custom drawing for the manipulator in Viewport 2.0.

All drawing should occur using the MUIDrawManager and any data cached in preDrawUI(). Raw OpenGL calls are not supported and if used behaviour will be undefined. Selection must still be handled in the draw() method, this method is only for display.

This method is only called when the manipulator needs to be drawn in Viewport 2.0.

We only need to override this function when we have some custom elements to draw other than the child manipulators in Viewport 2.0.

This function is empty in this base class.

Parameters

[in]	drawManager	The draw manager interface for drawing some simple UI
[in]	frameContext	Frame level context information

Examples:: footPrintManip/footPrintManip.cpp, lineManipContainer/lineManipContainer.h, and swissArmyManip/swissArmyManip.cpp.

void draw	(	M3dView &	view,
		const MDagPath &	path,
		M3dView::DisplayStyle	style,
		M3dView::DisplayStatus	status
	)

virtual

This method can be overloaded to customize the drawing of the child manipulators.

If the default draw is also required, this method should be called from the derived method.

Parameters

[in]	view	the view in which to draw
[in]	path	the current path
[in]	style	the display appearance
[in]	status	the display status

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

MStatus connectToDependNode ( const MObject & node )

virtual

This method connects the manipulator to the dependency node.

This is a virtual method and needs to be overridden from the plug-in.

Parameters

[in] node the node to which the manipulator should be connected

Returns: MS::kSuccess if successful, an error status otherwise. The base class returns MS::kFailure if there are no connections between manip values and plug values.

Examples:: componentScaleManip/componentScaleManip.cpp, customAttrManip/customAttrManip.cpp, footPrintManip/footPrintManip.cpp, lineManipContainer/lineManipContainer.h, manipOverride/customTriadManip.cpp, manipOverride/customTriadManip.h, manipOverride/manipOverride.cpp, moveManip/moveManip.cpp, rotateManip/rotateManip.cpp, surfaceBumpManip/surfaceBumpManip.cpp, and swissArmyManip/swissArmyManip.cpp.

MStatus createChildren ( )

virtual

This method should be overridden in user defined manipulators.

This method is called after the user node derived from MPxManipContainer is set up.

Examples:: componentScaleManip/componentScaleManip.cpp, customAttrManip/customAttrManip.cpp, footPrintManip/footPrintManip.cpp, lineManipContainer/lineManipContainer.h, manipOverride/customTriadManip.h, manipOverride/manipOverride.cpp, moveManip/moveManip.cpp, rotateManip/rotateManip.cpp, surfaceBumpManip/surfaceBumpManip.cpp, and swissArmyManip/swissArmyManip.cpp.

MManipData plugToManipConversion ( unsigned int manipIndex )

virtual

This virtual method calculates and returns the requested manipulator value, based upon the values of plugs on the nodes being manipulated.

To use, call addPlugToManipConversion() for each manipulator value (e.g. the start point of a distance manip) you want this method to calculate, then implement this method to calculate those manipulator values. Each manipulator value is identified by the unique index returned by the corresponding method of its functionset (e.g. MFnDistanceManip::startPointIndex).

Parameters

[in] manipIndex the index of the manipulator value to be calculated

Returns: New manipulator value.

Examples:: componentScaleManip/componentScaleManip.cpp.

MManipData manipToPlugConversion ( unsigned int plugIndex )

virtual

This virtual method calculates and returns the requested plug value, based upon the container's manipulator values.

To use, call addManipToPlugConversion() for each plug whose value you want this method to calculate then implement this method to calculate those plug values. Each plug is identified by the unique index returned by the addManipToPlugConversion() call.

Parameters

[in] plugIndex the index of the plug value to be calculated

Returns: New plug value.

Examples:: componentScaleManip/componentScaleManip.cpp.
