.SH DESCRIPTION
The QFontInfo class provides general information about fonts.
.PP
The QFont class might not always map exactly to the specified font for a paint device. The QFontInfo class provides information of the actual font that matched a QFont specification.
.PP
There are three ways you can create a QFontInfo object:
.IP 1
The QFontInfo constructor with a QFont creates a font info object for a screen-compatible font, i.e. the font must not be a printer font.
.IP 2
QWidget::fontInfo() returns the font info for a widget's font. This is equivalent to QFontInfo(widget->font()). Setting a new font for the widget later will not affect the font info object.
.IP 3
QPainter::fontInfo() returns the font info for a painter's current font. The font info object is automatically updated if somebody sets a new painter font (unlike the two above cases, which take a "snapshot" of a font).
.PP
Example:
.PP
.nf
.br
    QFont font("reykjavik",24);
.br
    QFontInfo fi(font);
.br
    if ( font.family() == fi.family() ) {
.br
        ; // got this font
.br
    } else {
.br
        ; // got fi.family() instead
.br
    }
.fi
.PP
See also: QFont and QFontMetrics.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QFontInfo::QFontInfo ( const QFont & font )"
Constructs a font info object for \fIfont.\fR
.PP
The font must be screen-compatible, i.e. a font you use when drawing text in widgets or pixmaps. If \fIfont\fR is a printer font, you'll probably get wrong results.
.PP
Use the QPainter::fontInfo() to get the font info when painting. This is a little slower than using this constructor, but it always gives correct results.
.SH "QFontInfo::QFontInfo ( const QFontInfo & fi )"
Constructs a copy of \fIfi.\fR
.SH "QFontInfo::~QFontInfo ()"
Destroys the font info object.
.SH "bool QFontInfo::bold () const"
Returns TRUE if weight() would return a greater than \fCQFont::Normal,\fR and FALSE otherwise.
.PP
See also: weight() and QFont::bold().
.SH "QFont::CharSet QFontInfo::charSet() const"
Returns the character set of the matched window system font.
.PP
See also: QFont::charSet().
.SH "bool QFontInfo::exactMatch () const"
Returns TRUE if the matched window system font is exactly the one specified by the font.
.PP
See also: QFont::exactMatch().
.SH "QString QFontInfo::family () const"
Returns the family name of the matched window system font.
.PP
See also: QFont::family().
.SH "bool QFontInfo::fixedPitch () const"
Returns the fixed pitch value of the matched window system font. A fixed pitch font is a font that has constant character pixel width.
.PP
See also: QFont::fixedPitch().
.SH "bool QFontInfo::italic () const"
Returns the italic value of the matched window system font.
.PP
See also: QFont::italic().
.SH "QFontInfo & QFontInfo::operator= ( const QFontInfo & fi )"
Font info assignment.
.SH "int QFontInfo::pointSize () const"
Returns the point size of the matched window system font.
.PP
See also: QFont::pointSize().
.SH "bool QFontInfo::rawMode () const"
Returns TRUE if the font is a raw mode font.
.PP
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.
.PP
See also: QFont::rawMode().
.SH "bool QFontInfo::strikeOut () const"
Returns the strike out value of the matched window system font.
.PP
See also: QFont::strikeOut().
.SH "QFont::StyleHint QFontInfo::styleHint() const"
Returns the style of the matched window system font.
.PP
Currently only returns the hint set in QFont.
.PP
See also: QFont::styleHint().
.SH "bool QFontInfo::underline () const"
Returns the underline value of the matched window system font.
.PP
See also: QFont::underline().
.SH "int QFontInfo::weight () const"
Returns the weight of the matched window system font.
.PP
See also:  QFont::weight() and bold().
