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>

<h3 class=fn><a name="StyleHint-enum"></a>QFont::StyleHint</h3>

<p> Style hints are used by the <a href="#fontmatching">font
    matching</a> algorithm to find an appropriate default family
if a selected font family is not available.
<ul>
<li><tt>QFont::AnyStyle</tt> - leaves the font matching algorithm to choose the
family. This is the default.
<li><tt>QFont::SansSerif</tt> - the font matcher prefer sans serif fonts.
<li><tt>QFont::Helvetica</tt> - is a synonym for <a href="#StyleHint-enum">SansSerif</a>.
<li><tt>QFont::Serif</tt> - the font matcher prefers serif fonts.
<li><tt>QFont::Times</tt> - is a synonym for <a href="#StyleHint-enum">Serif</a>.
<li><tt>QFont::TypeWriter</tt> - the font matcher prefers fixed pitch fonts.
<li><tt>QFont::Courier</tt> - a synonym for <a href="#StyleHint-enum">TypeWriter</a>.
<li><tt>QFont::OldEnglish</tt> - the font matcher prefers decorative fonts.
<li><tt>QFont::Decorative</tt> - is a synonym for <a href="#StyleHint-enum">OldEnglish</a>.
<li><tt>QFont::System</tt> - the font matcher prefers system fonts.
</ul>
<h3 class=fn><a name="StyleStrategy-enum"></a>QFont::StyleStrategy</h3>

<p> The style strategy tells the <a href="#fontmatching">font
    matching</a> algorithm what type of fonts should be used to
find an appropriate default family.
<p> The following strategies are available:
<ul>
<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
</ul>
