<hr><a name="details"></a><h2>Detailed Description</h2>
<p> The QFont class specifies a font used for drawing text.
<p>
<p> When you create a QFont object you specify various attributes that
you want the font to have. Qt will use the font with the specified
attributes, or if no matching font exists, Qt will use the closest
matching installed font. The attributes of the font that is actually
used are retrievable from a <a href="qfontinfo.html">QFontInfo</a> object. If the window system
provides an exact match <a href="#exactMatch">exactMatch</a>() returns TRUE. Use <a href="qfontmetrics.html">QFontMetrics</a>
to get measurements, e.g. the pixel length of a string using
<a href="qfontmetrics.html#width">QFontMetrics::width</a>().
<p> Use <a href="qapplication.html#setFont">QApplication::setFont</a>() to set the application's default font.
<p> If a choosen X11 font does not include all the characters that need
to be displayed, QFont will try to find the characters in the
nearest equivalent fonts. When a <a href="qpainter.html">QPainter</a> draws a character from a
font the QFont will report whether or not it has the character; if
it does not, QPainter will draw an unfilled square.
<p> Create QFonts like this:
<pre>
QFont serifFont( "Times", 10, Bold );
QFont sansFont( "Helvetica [Cronyx]", 12 );
</pre>
<p> The attributes set in the constructor can also be set later, e.g.
<a href="#setFamily">setFamily</a>(), <a href="#setPointSize">setPointSize</a>(), <a href="#setPointSizeFloat">setPointSizeFloat</a>(), <a href="#setWeight">setWeight</a>() and
<a href="#setItalic">setItalic</a>(). The remaining attributes must be set after
contstruction, e.g. <a href="#setBold">setBold</a>(), <a href="#setUnderline">setUnderline</a>(), <a href="#setStrikeOut">setStrikeOut</a>() and
<a href="#setFixedPitch">setFixedPitch</a>(). <a href="qfontinfo.html">QFontInfo</a> objects should be created <em>after</em> the
font's attributes have been set. A QFontInfo object will not change,
even if you change the font's attributes. The corresponding "get"
functions, e.g. <a href="#family">family</a>(), <a href="#pointSize">pointSize</a>(), etc., return the values that
were set, even though the values used may differ. The actual values
are available from a QFontInfo object.
<p> If the requested font family is unavailable you can influence the
<a href="#fontmatching">font matching algorithm</a> by choosing a
particular <a href="#StyleHint-enum">QFont::StyleHint</a> and <a href="#StyleStrategy-enum">QFont::StyleStrategy</a> with
<a href="#setStyleHint">setStyleHint</a>(). The default family (corresponding to the current
style hint) is returned by <a href="#defaultFamily">defaultFamily</a>().
<p> The font-matching algorithm has a <a href="#lastResortFamily">lastResortFamily</a>() and
<a href="#lastResortFont">lastResortFont</a>() in cases where a suitable match cannot be found.
You can provide substitutions for font family names using
<a href="#insertSubstitution">insertSubstitution</a>() and <a href="#insertSubstitutions">insertSubstitutions</a>(). Substitutions can be
removed with <a href="#removeSubstitution">removeSubstitution</a>(). Use <a href="#substitute">substitute</a>() to retrieve a
family's first substitute, or the family name itself if it has no
substitutes. Use <a href="#substitutes">substitutes</a>() to retrieve a list of a family's
substitutes (which may be empty).
<p> Every QFont has a <a href="#key">key</a>() which you can use, for example, as the key
in a cache or dictionary. If you want to store a user's font
preferences you could use <a href="qsettings.html">QSettings</a>, writing the font information
with <a href="#toString">toString</a>() and reading it back with <a href="#fromString">fromString</a>(). The
<a href="#operator-lt-lt">operator<<</a>() and <a href="#operator-gt-gt">operator>></a>() functions are also available, but they
work on a data stream.
<p> It is possible to set the height of characters shown on the screen
to a specified number of pixels with <a href="#setPixelSize">setPixelSize</a>(); however using
<a href="#setPointSize">setPointSize</a>() has a similar effect and provides device
independence.
<p> Under the X Window System you can set a font using its system
specific name with <a href="#setRawName">setRawName</a>().
<p> Loading fonts can be expensive, especially on X11. QFont contains
extensive optimizations to make the copying of QFont objects fast,
and to cache the results of the slow window system functions it
depends upon.
<p> <a name="fontmatching"></a>
The font matching algorithm works as follows:
<ol type=1>
<li> The specified font family is searched for.
<li> If not found, the <a href="#styleHint">styleHint</a>() is used to select a replacement
family.
<li> Each replacement font family is searched for.
<li> If none of these are found or there was no styleHint(), "helvetica"
will be searched for.
<li> If "helvetica" isn't found Qt will try the <a href="#lastResortFamily">lastResortFamily</a>().
<li> If the lastResortFamily() isn't found Qt will try the
<a href="#lastResortFont">lastResortFont</a>() which will always return a name of some kind.
</ol>
<p> Once a font is found, the remaining attributes are matched in order of
priority:
<ol type=1>
<li> <a href="#fixedPitch">fixedPitch</a>()
<li> <a href="#pointSize">pointSize</a>() (see below)
<li> <a href="#weight">weight</a>()
<li> <a href="#italic">italic</a>()
</ol>
<p> If you have a font which matches on family, even if none of the
other attributes match, this font will be chosen in preference to a
font which doesn't match on family but which does match on the other
attributes. This is because font family is the dominant search
criteria.
<p> The point size is defined to match if it is within 20% of the
requested point size. When several fonts match and are only
distinguished by point size, the font with the closest point size to
the one requested will be chosen.
<p> The actual family, font size, weight and other font attributes used
for drawing text will depend on what's available for the chosen
family under the window system. A <a href="qfontinfo.html">QFontInfo</a> object can be used to
determine the actual values used for drawing the text.
<p> Examples:
<p> <pre>
QFont f("Helvetica");
</pre>
If you had both an Adobe and a Cronyx Helvetica, you might get
either.
<p> <pre>
QFont f1( "Helvetica [Cronyx]" ); // Qt 3.x
QFont f2( "Cronyx-Helvetica" ); // Qt 2.x compatibility
</pre>
You can specify the foundry you want in the family name. Both fonts,
f1 and f2, in the above example will be set to "Helvetica
[Cronyx]".
<p> To determine the attributes of the font actually used in the window
system, use a QFontInfo object, e.g.
<pre>
<a href="qfontinfo.html">QFontInfo</a> info( f1 );
<a href="qstring.html">QString</a> family = info.<a href="qfontinfo.html#family">family</a>();
</pre>
<p> To find out font metrics use a <a href="qfontmetrics.html">QFontMetrics</a> object, e.g.
<pre>
<a href="qfontmetrics.html">QFontMetrics</a> fm( f1 );
int pixelWidth = fm.<a href="qfontmetrics.html#width">width</a>( "How many pixels wide is this text?" );
int pixelHeight = fm.<a href="qfontmetrics.html#height">height</a>();
</pre>

<li><tt>QFont::PreferDefault</tt> - the default style strategy. It does not prefer
any type of font.
<li><tt>QFont::PreferBitmap</tt> - prefers bitmap fonts (as opposed to outline fonts). On X11, this will cause
Qt to disregard fonts from the Xft font extension.
<li><tt>QFont::PreferDevice</tt> - prefers device fonts.
<li><tt>QFont::PreferOutline</tt> - prefers outline fonts (as opposed to bitmap fonts).
<li><tt>QFont::ForceOutline</tt> - forces the use of outline fonts.
<li><tt>QFont::NoAntialias</tt> - don't antialias the fonts.
<li><tt>QFont::PreferAntialias</tt> - antialias if possible.
</ul><p> Any of these may be OR-ed with one of these flags:
<ul>
<li><tt>QFont::PreferMatch</tt> - prefer an exact match. The font matcher will try to
use the exact font size that has been specified.
<li><tt>QFont::PreferQuality</tt> - prefer the best quality font. The font matcher
will use the nearest standard point size that the font supports.
</ul>
<h3 class=fn><a name="Weight-enum"></a>QFont::Weight</h3>
<p> Qt uses a weighting scale from 0 to 99 similar to, but not
the same as, the scales used in Windows or CSS. A weight of
0 is ultralight, whilst 99 will be an extremely black.
<p> This enum contains the predefined font weights:
<ul>
<li><tt>QFont::Light</tt> - 25
<li><tt>QFont::Normal</tt> - 50
<li><tt>QFont::DemiBold</tt> - 63
<li><tt>QFont::Bold</tt> - 75
<li><tt>QFont::Black</tt> - 87

</h3>
Saves the glyphs in the font that have previously been accessed
as a QPF file. If <em>all</em> is TRUE (the default), then before saving,
all glyphs are marked as used.
<p> If the font is large and you are sure that only a subset of characters
will ever be required on the target device, passing FALSE for the
<em>all</em> parameter can save significant disk space.
<p> Note that this function is only applicable on Qt/Embedded.
<h3 class=fn>bool <a name="rawMode"></a>QFont::rawMode () const

<h3 class=fn><a href="qstring.html">QString</a> <a name="rawName"></a>QFont::rawName () const
</h3>
Returns the name of the font within the underlying window system.

<h3 class=fn>void <a name="setFamily"></a>QFont::setFamily ( const <a href="qstring.html">QString</a> & family )
</h3>
Sets the family name of the font. The name is case insensitive and
may include a foundry name.
<p> The <em>family</em> name may optionally also include a foundry name, e.g.
"Helvetica [Cronyx]". (The Qt 2.x syntax, i.e. "Cronyx-Helvetica",
is also supported.) If the <em>family</em> is available from more than one
foundry and the foundry isn't specified, an arbitrary foundry is
chosen. If the family isn't available a family will be set using the
<a href="#fontmatching">font matching</a> algorithm.

<h3 class=fn>void <a name="setItalic"></a>QFont::setItalic ( bool enable )
</h3>
If <em>enable</em> is TRUE, italic is set on; otherwise italic is set off.
<p> <p>See also <a href="#italic">italic</a>() and <a href="qfontinfo.html">QFontInfo</a>.
<p>Examples: <a href="fileiconview-example.html#x1541">fileiconview/qfileiconview.cpp</a>, <a href="simple-qfont-demo-walkthrough.html#x2392">fonts/simple-qfont-demo/viewer.cpp</a> and <a href="themes-example.html#x298">themes/metal.cpp</a>.
<h3 class=fn>void <a name="setPixelSize"></a>QFont::setPixelSize ( int pixelSize )
</h3> Sets the font size to <em>pixelSize</em> pixels.
<p> Using this function makes the font device dependent. Use
<a href="#setPointSize">setPointSize</a>() or <a href="#setPointSizeFloat">setPointSizeFloat</a>() to set the size of the font in
a device independent manner.
<p> <p>See also <a href="#pixelSize">pixelSize</a>().
<p>Example: <a href="qwerty-example.html#x629">qwerty/qwerty.cpp</a>.
<h3 class=fn>void <a name="setPixelSizeFloat"></a>QFont::setPixelSizeFloat ( float pixelSize )
</h3> <b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
<p> Sets the logical pixel height of font characters when shown on
the screen to <em>pixelSize</em>.
<h3 class=fn>void <a name="setPointSize"></a>QFont::setPointSize ( int pointSize )
</h3> Sets the point size to <em>pointSize</em>. The point size must be greater
than zero.
<p> <p>See also <a href="#pointSize">pointSize</a>() and <a href="#setPointSizeFloat">setPointSizeFloat</a>().
<p>Example: <a href="simple-qfont-demo-walkthrough.html#x2393">fonts/simple-qfont-demo/viewer.cpp</a>.
<h3 class=fn>void <a name="setPointSizeFloat"></a>QFont::setPointSizeFloat ( float pointSize )
</h3> Sets the point size to <em>pointSize</em>. The point size must be greater
than zero. The requested precision may not be achieved on all platforms.
<p> <p>See also <a href="#pointSizeFloat">pointSizeFloat</a>(), <a href="#setPointSize">setPointSize</a>() and <a href="#setPixelSize">setPixelSize</a>().
<h3 class=fn>void <a name="setRawMode"></a>QFont::setRawMode ( bool enable )
</h3>
If <em>enable</em> is TRUE, turns raw mode on; otherwise turns raw mode
off. This function only has an affect under X11.
<p> If raw mode is enabled, Qt will search for an X font with a complete
font name matching the family name, ignoring all other values set for
the QFont. If the font name matches several fonts, Qt will use the
first font returned by X. <a href="qfontinfo.html">QFontInfo</a> <em>cannot</em> be used to fetch
information about a QFont using raw mode (it will return the values
set in the QFont for all parameters, including the family name).
<p> <b>Warning:</b> Do not use raw mode unless you really, really need it! In
most (if not all) cases, <a href="#setRawName">setRawName</a>() is a much better choice.
<p> <p>See also <a href="#rawMode">rawMode</a>() and <a href="#setRawName">setRawName</a>().
<h3 class=fn>void <a name="setRawName"></a>QFont::setRawName ( const <a href="qstring.html">QString</a> & name )
</h3>
Sets a font by its system specific name. The function is in
particular useful under X, where system font settings (for example
X resources) are usually available in XLFD (X Logical Font
Description) form only. You can pass an XLFD as <em>name</em> to this
function.
<p> In Qt 2.0 and later, a font set with <a href="#setRawName">setRawName</a>() is still a
full-featured QFont. It can be queried (for example with <a href="#italic">italic</a>())
or modified (for example with <a href="#setItalic">setItalic</a>() ) and is therefore also
suitable for rendering rich text.
<p> If Qt's internal font database cannot resolve the raw name, the font
becomes a raw font with <em>name</em> as its family.
<p> Note that the present implementation does not handle
wildcards in XLFDs well, and that font aliases (file <tt>fonts.alias</tt>
in the font directory on X11) are not supported.
<p> <p>See also <a href="#rawName">rawName</a>(), <a href="#setRawMode">setRawMode</a>() and <a href="#setFamily">setFamily</a>().

<h3 class=fn>void <a name="setStyleHint"></a>QFont::setStyleHint ( <a href="qfont.html#StyleHint-enum">StyleHint</a> hint, <a href="qfont.html#StyleStrategy-enum">StyleStrategy</a> strategy = PreferDefault )
</h3> Sets the style hint and strategy to <em>hint</em> and <em>strategy</em>,
respectively.
