DESCRIPTION
The QFontInfo class provides general information about
fonts.
The QFontInfo class mirrors QFont exactly, but where QFont
access functions return set values, QFontInfo returns the
values that apply to the font in use.
For example, when the program asks for a 25pt Courier font
on a machine that has a 24pt Courier font but not a
scalable one, QFont will (normally) use the 24pt Courier
for rendering. In this case, QFont::pointSize() returns 25
and QFontInfo::pointSize() 24.
The access functions in QFontInfo mirror QFont exactly,
except for this difference.
There are three ways to create a QFontInfo object.
The QFontInfo constructor with a QFont creates a font info
object for a screen-compatible font, i.e. the font can not
be a printer font.
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 does not affect
the font info object.
QPainter::fontInfo() returns the font info for a painter's
current font. The font info object is automatically
two above cases, which take a" snapshot" of a font.
See also QFont and QFontMetrics.
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. If font is a
printer font, you'll probably get wrong results.
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.
QFontInfo::QFontInfo ( const QFontInfo & fi )
Constructs a copy of fi.
QFontInfo::~QFontInfo ()
Destructs the font info object.
bool QFontInfo::bold () const
Returns TRUE if weight() would return a greater than
QFont::Normal, and FALSE otherwise.
See also weight() and QFont::bold().
QFont::CharSet QFontInfo::charSet() const
Returns the character set of the matched window system
font.
See also QFont::charSet().
bool QFontInfo::exactMatch () const
Returns TRUE if the matched window system font is exactly
the one specified by the font.
See also QFont::exactMatch().
QString QFontInfo::family () const
Returns the family name of the matched window system font.
See also QFont::family().
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.
See also QFont::fixedPitch().
Returns the italic value of the matched window system
font.
See also QFont::italic().
QFontInfo & QFontInfo::operator= ( const QFontInfo & fi )
Font info assignment.
int QFontInfo::pointSize () const
Returns the point size of the matched window system font.
See also QFont::pointSize().
bool QFontInfo::rawMode () const
Returns TRUE if the font is a raw mode font.
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().
bool QFontInfo::strikeOut () const
Returns the strike out value of the matched window system
font.
See also QFont::strikeOut().
QFont::StyleHint QFontInfo::styleHint() const
Returns the style of the matched window system font.
Currently only returns the hint set in QFont.
See also QFont::styleHint().
bool QFontInfo::underline () const
Returns the underline value of the matched window system
font.
See also QFont::underline().
int QFontInfo::weight () const
Returns the weight of the matched window system font.
See also QFont::weight() and bold().
