Detailed Description

The QSArgument class provides storage for various datatypes used in QSObjectFactory::create() calls.

When the user writes Qt Script code like this:

    var x = new AnotherCppObject( arg1, arg2 ); // Qt Script
  
the arguments are passed to the QSObjectFactory::create() call as a QValueList of QSArguments. A QSArgument can hold a QVariant, a QObject pointer or a void pointer. The type held by a QSArgument is returned by type() and the value is returned by variant(), qobject(), or ptr(), depending on the QSArgument type.
