DESCRIPTION
       The QSize class defines the size of a two-dimensional
       object.

       A size is specified by a width and a height.

       The coordinate type is QCOORD (defined in qwindowdefs.h as
       int). The minimum value of QCOORD is QCOORD_MIN
       (-2147483648) and the maximum value is QCOORD_MAX
       (2147483647).

MEMBER FUNCTION DOCUMENTATION
QSize::QSize ()
       Constructs a size with invalid (negative) width and
       height.

QSize::QSize ( int w, int h )
       Constructs a size with width w and height h.

QSize QSize::boundedTo ( const QSize & otherSize ) const
       Returns a size with the minimum width and height of this
       size and otherSize.

QSize QSize::expandedTo ( const QSize & otherSize ) const
       Returns a size with the maximum width and height of this
       size and otherSize.

int QSize::height () const
       Returns the height.

       See also width().

       Examples: qfd/qfd.cpp

bool QSize::isEmpty () const
       Returns TRUE if the width is <= 0 or the height is <= 0,
       otherwise FALSE.

bool QSize::isNull () const
       Returns TRUE if the width is 0 and the height is 0,
       otherwise FALSE.

bool QSize::isValid () const
       Returns TRUE if the width is equal to or greater than 0
       and the height is equal to or greater than 0, otherwise
       FALSE.

QSize & QSize::operator*= ( double c )
       Multiplies both the width and height with c and returns a
       reference to the size.

       Note that the result is truncated.

QSize & QSize::operator*= ( int c )
       Multiplies both the width and height with c and returns a
       reference to the size.

QSize & QSize::operator+= ( const QSize & s )
       Adds s to the size and returns a reference to this size.

       Example:

	   QSize s(  3, 7 );
	   QSize r( -1, 4 );
	   s += r;		       // s becomes (2,11)

QSize & QSize::operator-= ( const QSize & s )
       Subtracts s from the size and returns a reference to this
       size.

       Example:

	   QSize s(  3, 7 );
	   QSize r( -1, 4 );
	   s -= r;		       // s becomes (4,3)

QSize & QSize::operator/= ( double c )
       Divides both the width and height by c and returns a
       reference to the size.

       Note that the result is truncated.

QSize & QSize::operator/= ( int c )
       Divides both the width and height by c and returns a
       reference to the size.

QCOORD & QSize::rheight ()
       Returns a reference to the height.

       Using a reference makes it possible to directly manipulate
       the height.

       Example:

	   QSize s( 100, 10 );
	   s.rheight() += 5;	       // s becomes (100,15)

       See also rwidth().

QCOORD & QSize::rwidth ()
       Returns a reference to the width.

       Using a reference makes it possible to directly manipulate
       the width.

       Example:

	   QSize s( 100, 10 );
	   s.rwidth() += 20;	       // s becomes (120,10)

       See also rheight().

void QSize::setHeight ( int h )
       Sets the height to h.

QSize(3qt)					       QSize(3qt)

       See also height() and setWidth().

void QSize::setWidth ( int w )
       Sets the width to w.

       See also width() and setHeight().

void QSize::transpose ()
       Swaps the values of width and height.

int QSize::width () const
       Returns the width.

       See also height().

       Examples: qfd/qfd.cpp

RELATED FUNCTION DOCUMENTATION
QSize operator* (const QSize & s, int c)
       Multiplies s by c and returns the result.

QSize operator* (const QSize & s, double c)
       Multiplies s by c and returns the result.

QSize operator* (int c, const QSize & s)
       Multiplies s by c and returns the result.

bool operator!= (const QSize & s1, const QSize & s2)
       Returns TRUE if s1 and s2 are different, or FALSE if they
       are equal.

QSize operator/ (const QSize & s, int c)
       Divides s by c and returns the result.

bool operator== (const QSize & s1, const QSize & s2)
       Returns TRUE if s1 and s2 are equal, or FALSE if they are
       different.

QSize operator/ (const QSize & s, double c)
       Divides s by c and returns the result.

       Note that the result is truncated.

QDataStream & operator<;< (QDataStream & s, const QSize & sz)
       Writes the size to the stream and returns a reference to
       the stream.

       See also Format of the QDataStream operators

QDataStream & operator>> (QDataStream & s, QSize & sz)
       Reads the size from the stream and returns a reference to
       the stream.
