.SH DESCRIPTION
The TQFontInfo class provides general information about fonts.
.PP
The TQFontInfo class provides the same access functions as TQFont, e.g. family(), pointSize(), italic(), weight(), fixedPitch(), styleHint() etc. But whilst the TQFont access functions return the values that were set, a TQFontInfo object returns the values that apply to the font that will actually be used to draw the text.
.PP
For example, when the program asks for a 25pt Courier font on a machine that has a non-scalable 24pt Courier font, TQFont will (normally) use the 24pt Courier for rendering. In this case, TQFont::pointSize() returns 25 and TQFontInfo::pointSize() returns 24.
.PP
There are three ways to create a TQFontInfo object. <ol type=1>
.IP 1
Calling the TQFontInfo constructor with a TQFont 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 \fInot\fR updated.
.IP 2
TQWidget::fontInfo() returns the font info for a widget's font. This is equivalent to calling TQFontInfo(widget->font()). If the widget's font is changed later, the font info object is \fInot\fR updated.
.IP 3
TQPainter::fontInfo() returns the font info for a painter's current font. If the painter's font is changed later, the font info object is \fInot\fR updated.
.PP
<sup>*</sup> If you use a printer font the values returned may be inaccurate. Printer fonts are not always accessible so the nearest screen font is used if a printer font is supplied.
.PP
See also TQFont, TQFontMetrics, TQFontDatabase, Graphics Classes, and Implicitly and Explicitly Shared Classes.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "TQFontInfo::TQFontInfo ( const TQFont & 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, not TQPicture or TQPrinter.
.PP
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.
.PP
Use TQPainter::fontInfo() to get the font info when painting. This will give correct results also when painting on paint device that is not screen-compatible.
.SH "TQFontInfo::TQFontInfo ( const TQFont & font, TQFont::Script script )"
Constructs a font info object for \fIfont\fR using the specified \fIscript\fR.
.SH "TQFontInfo::TQFontInfo ( const TQFontInfo & fi )"
Constructs a copy of \fIfi\fR.
.SH "TQFontInfo::~TQFontInfo ()"
Destroys the font info object.
.SH "bool TQFontInfo::bold () const"
Returns TRUE if weight() would return a value greater than TQFont::Normal; otherwise returns FALSE.
.PP
See also weight() and TQFont::bold().
.PP
Example: qfd/fontdisplayer.cpp.
.SH "bool TQFontInfo::exactMatch () const"
Returns TRUE if the matched window system font is exactly the same as the one specified by the font; otherwise returns FALSE.
.PP
See also TQFont::exactMatch().
.SH "TQString TQFontInfo::family () const"
Returns the family name of the matched window system font.
.PP
See also TQFont::family().
.PP
Examples:
.)l fonts/simple-tqfont-demo/viewer.cpp and qfd/fontdisplayer.cpp.
.SH "bool TQFontInfo::fixedPitch () const"
Returns the fixed pitch value of the matched window system font.
.PP
See also TQFont::fixedPitch().
.SH "bool TQFontInfo::italic () const"
Returns the italic value of the matched window system font.
.PP
See also TQFont::italic().
.PP
Example: qfd/fontdisplayer.cpp.
.SH "TQFontInfo & TQFontInfo::operator= ( const TQFontInfo & fi )"
Assigns the font info in \fIfi\fR.
.SH "int TQFontInfo::pixelSize () const"
Returns the pixel size of the matched window system font.
.PP
See also TQFont::pointSize().
.SH "int TQFontInfo::pointSize () const"
Returns the point size of the matched window system font.
.PP
See also TQFont::pointSize().
.PP
Examples:
.)l fonts/simple-tqfont-demo/viewer.cpp and qfd/fontdisplayer.cpp.
.SH "bool TQFontInfo::rawMode () const"
Returns TRUE if the font is a raw mode font; otherwise returns FALSE.
.PP
If it is a raw mode font, all other functions in TQFontInfo will return the same values set in the TQFont, regardless of the font actually used.
.PP
See also TQFont::rawMode().
.SH "TQFont::StyleHint TQFontInfo::styleHint () const"
Returns the style of the matched window system font.
.PP
Currently only returns the style hint set in TQFont.
.PP
See also TQFont::styleHint() and TQFont::StyleHint.
.SH "int TQFontInfo::weight () const"
Returns the weight of the matched window system font.
.PP
See also TQFont::weight() and bold().
