DESCRIPTION

       The QFontInfo class provides general information about fonts.

       The QFontInfo class provides the same access functions as QFont, e.g. family(), pointSize(), italic(), weight(), fixedPitch(), styleHint()
       etc. But whilst the QFont access functions return the values that were set, a QFontInfo object returns the values that apply to the font
       that will actually be used to draw the text.

       For example, when the program asks for a 25pt Courier font on a machine that has a non-scalable 24pt Courier font, QFont will (normally)
       use the 24pt Courier for rendering. In this case, QFont::pointSize() returns 25 and QFontInfo::pointSize() returns 24.

       There are three ways to create a QFontInfo object. <ol type=1>

       1      Calling the QFontInfo constructor with a QFont creates a font info object for a screen-compatible font, i.e. the font cannot be a
	      printer font<sup>*</sup>. If the font is changed later, the font info object is not updated.

       2      QWidget::fontInfo() returns the font info for a widget's font. This is equivalent to calling QFontInfo(widget->font()). If the
	      widget's font is changed later, the font info object is not updated.

       3      QPainter::fontInfo() returns the font info for a painter's current font. The font info object is automatically updated if you set a
	      new painter font.

       <sup>*</sup> If you use a printer font the values returned will almost certainly be inaccurate. Printer fonts are not always accessible so
       the nearest screen font is used if a printer font is supplied.

       See also QFont, QFontMetrics, QFontDatabase, Graphics Classes, and Implicitly and Explicitly Shared Classes.

MEMBER FUNCTION DOCUMENTATION

QFontInfo::QFontInfo ( const QFont & font )
       Constructs a font info object for font.

       The font must be screen-compatible, i.e. a font you use when drawing text in widgets or pixmaps, not QPicture or QPrinter.

       The font info object holds the information for the font that is passed in the constructor at the time it is created, and is not updated if
       the font's attributes are changed later.

       Use the QPainter::fontInfo() function to get the font info when painting. This is a little slower than using this constructor, but it
       always gives correct results because the font info data is updated.

QFontInfo::QFontInfo ( const QFontInfo & fi )
       Constructs a copy of fi.

QFontInfo::~QFontInfo ()
       Destroys the font info object.

bool QFontInfo::bold () const
       Returns TRUE if weight() would return a value greater than QFont::Normal; otherwise returns FALSE.

       See also weight() and QFont::bold().

bool QFontInfo::exactMatch () const
       Returns TRUE if the matched window system font is exactly the same as the one specified by the font; otherwise returns FALSE.

       See also QFont::exactMatch().

QString QFontInfo::family () const
       Returns the family name of the matched window system font.

       See also QFont::family().

       Example: fonts/simple-qfont-demo/viewer.cpp.

bool QFontInfo::fixedPitch () const
       Returns the fixed pitch value of the matched window system font.

       See also QFont::fixedPitch().

bool QFontInfo::italic () const
       Returns the italic value of the matched window system font.

       See also QFont::italic().

QFontInfo &; QFontInfo::operator= ( const QFontInfo & fi )
       Assigns the font info in fi.

int QFontInfo::pixelSize () const
       Returns the pixel size of the matched window system font.

       See also QFont::pointSize().

int QFontInfo::pointSize () const
       Returns the point size of the matched window system font.

       See also QFont::pointSize().

       Example: fonts/simple-qfont-demo/viewer.cpp.

bool QFontInfo::rawMode () const
       Returns TRUE if the font is a raw mode font; otherwise returns FALSE.

       If it is a raw mode font, all other functions in QFontInfo will return the same values set in the QFont, regardless of the font actually
       used.

       See also QFont::rawMode().

QFont::StyleHint QFontInfo::styleHint () const
       Returns the style of the matched window system font.

       Currently only returns the style hint set in QFont.

       See also QFont::styleHint() and QFont::StyleHint.

int QFontInfo::weight () const
       Returns the weight of the matched window system font.

       See also QFont::weight() and bold().
