Class Description

Base class for interactive tool commands.

This is the base class for interactive tool commands.

An interactive tool command is a command that can be invoked as a MEL command or from within a user defined context (see MPxContext).

Tool commands have the same functionality as MPxCommands, but include several additional methods for use in interactive contexts: setUpInteractive, cancel, finalize, and doFinalize.

Examples:: helixTool/helixTool.cpp, listRichSelectionCmd/listRichSelectionCmd.cpp, manipOverride/manipOverride.cpp, moveNumericTool/moveNumericTool.cpp, moveTool/moveTool.cpp, and richMoveCmd/richMoveCmd.cpp.

Constructor & Destructor Documentation

OPENMAYA_MAJOR_NAMESPACE_OPEN MPxToolCommand ( )

Class constructor.

This constructor should only be called from within a user context that uses this tool.

The context is responsible for setting up the internal state variables for the derived tools and for creating a command string for journalling.

~MPxToolCommand ( )

virtual

Class Destructor.

The user can override this method to free up any allocated data within the derived MPxToolCommand class.

Member Function Documentation

virtual MStatus doIt ( const MArgList & args )

pure virtual

This method should perform a command by setting up internal class data and then calling the redoIt method.

The actual action performed by the command should be done in the redoIt method. This is a pure virtual method, and must be overridden in derived classes.

Parameters

[in] args List of arguments passed to the command.

Returns: Status code

Status Codes:

MS::kSuccess The command was successful
MS::kFailure An error occured during the command

Reimplemented from MPxCommand.

Implemented in MPxPolyTweakUVInteractiveCommand.

Examples:: helixTool/helixTool.cpp, listRichSelectionCmd/listRichSelectionCmd.cpp, manipOverride/manipOverride.cpp, moveNumericTool/moveNumericTool.cpp, moveTool/moveTool.cpp, and richMoveCmd/richMoveCmd.cpp.

MStatus cancel ( )

virtual

This method cancels the command.

The user should override this method when the original program state needs to be restored.

Returns: Status code

Status Codes:

MS::kSuccess The cancel was successfull.
MS::kFailure Object error.

Reimplemented in MPxPolyTweakUVInteractiveCommand.

MStatus finalize ( )

virtual

This method is used to create a string representing the command and its arguments.

Users should override this method and contruct an MArgList and then pass it to doFinalize for journalling.

Returns: Status code

Status Codes:

MS::kSuccess The finalize was successfull.
MS::kFailure Object error.

Reimplemented in MPxPolyTweakUVInteractiveCommand.

Examples:: helixTool/helixTool.cpp, listRichSelectionCmd/listRichSelectionCmd.cpp, manipOverride/manipOverride.cpp, moveNumericTool/moveNumericTool.cpp, moveTool/moveTool.cpp, and richMoveCmd/richMoveCmd.cpp.

const char * className ( )

static

Returns the name of this class.

Returns: Name of this class.

MStatus doFinalize ( MArgList & command )

protected

USE _doFinalize() IN SCRIPT.

Call this method with an MArgList representing your command.

This method will register the command with the undo manager for journalling.

Parameters

[in] command An MArgList reference representing an equivalent MEL command

Returns: Status code

Status Codes:

MS::kSuccess The doFinalize was successfull.
MS::kFailure Object error.

Examples:: helixTool/helixTool.cpp, listRichSelectionCmd/listRichSelectionCmd.cpp, manipOverride/manipOverride.cpp, moveNumericTool/moveNumericTool.cpp, moveTool/moveTool.cpp, and richMoveCmd/richMoveCmd.cpp.
