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.

- QSArgument::QObjectPtr - Holds a QObject pointer
- QSArgument::VoidPointer - Holds an untyped pointer (void*)
Member Function Documentation
QSArgument::QSArgument ()
Creates an invalid QSArgument
QSArgument::QSArgument ( const QVariant & v )
Creates a QSArgument which holds the variant v as its value and
is of type Variant.
QSArgument::QSArgument ( QObject * o )
Creates a QSArgument which holds the QObject pointer o as its value
and is of type QObjectPtr.
QSArgument::QSArgument ( void * p )
Creates a QSArgument which holds the pointer p as its value and
is of type VoidPointer.
void * QSArgument::ptr () const
If this QSArgument's type() is VoidPointer, it returns the void pointer;
otherwise returns 0.
QObject * QSArgument::qobject () const
If this QSArgument's type() is QObjectPtr, it returns the object
pointer; otherwise returns 0.
Type QSArgument::type () const
Returns the type of this QSArgument. This can be Invalid, Variant, QObjectPtr, or VoidPointer
See also typeName().
QString QSArgument::typeName () const
Returns the type name of this argument.
QVariant QSArgument::variant () const
If this QSArgument's type() is Variant, it returns the variant value;
otherwise returns an invalid variant.
