MArgList

The MArgList class provides an entry point for a list of arguments that are passed to your command plug-in.

MArgList is similar to the argc and argv parameters in C and C++. However, an important difference between MArgList and argv/argc parameters is that the zeroth element of an MArgList is the first argument to the command and not the command name itself.

The list of arguments is passed to MPxCommand::doIt(). For example,

MStatus doHelix::doIt( const MArgList& args )

Use a loop to parse the individual arguments from the list. For example,

// Parse the arguments.
for ( i = 0; i < args.length(); i++ )
    if ( MString( "-p" ) == args.asString( i ) )
        pitch = args.asDouble( ++i );
    else if ( MString( "-r" ) == args.asString( i ) )
        radius = args.asDouble( ++i );
