available in the underlying window system.</p>
<p>The most common uses of this class are to query the database for
the list of font <a href="qfontdatabase.html#families">families</a>() and for the <a href="qfontdatabase.html#pointSizes">pointSizes</a>() and <a href="qfontdatabase.html#styles">styles</a>() that are available for
each family. An alternative to <a href="qfontdatabase.html#pointSizes">pointSizes</a>() is <a href="qfontdatabase.html#smoothSizes">smoothSizes</a>() which returns
the sizes at which a given family and style will look
attractive.</p>
<p>If the font family is available from two or more foundries the
foundry name is included in the family name; for example:
"Helvetica [Adobe]" and "Helvetica [Cronyx]". When you specify a
family, you can either use the old hyphenated "foundry-family"
format or the bracketed "family [foundry]" format; for example:
"Cronyx-Helvetica" or "Helvetica [Cronyx]". If the family has a
foundry it is always returned using the bracketed format, as is the
case with the value returned by <a href="qfontdatabase.html#families">families</a>().</p>
<p>The <a href="qfontdatabase.html#font">font</a>() function
returns a <a href="qfont.html">QFont</a> given a family, style and
point size.</p>
<p>A family and style combination can be checked to see if it is
<a href="qfontdatabase.html#italic">italic</a>() or <a href="qfontdatabase.html#bold">bold</a>(), and to retrieve its <a href="qfontdatabase.html#weight">weight</a>(). Similarly we can call
<a href="qfontdatabase.html#isBitmapScalable">isBitmapScalable</a>(),
<a href="qfontdatabase.html#isSmoothlyScalable">isSmoothlyScalable</a>(),
<a href="qfontdatabase.html#isScalable">isScalable</a>() and
<a href="qfontdatabase.html#isFixedPitch">isFixedPitch</a>().</p>
<p>Use the <a href="qfontdatabase.html#styleString">styleString</a>() to obtain a text
version of a style.</p>
<p>The QFontDatabase class also supports some static functions, for
example, <a href="qfontdatabase.html#standardSizes">standardSizes</a>(). You can
retrieve the description of a writing system using <a href="qfontdatabase.html#writingSystemName">writingSystemName</a>(), and
a sample of characters in a writing system with <a href="qfontdatabase.html#writingSystemSample">writingSystemSample</a>().</p>
<p>Example:</p>
<pre class="cpp">
<span class="type">QFontDatabase</span> database;
<span class="type"><a href="qtreewidget.html">QTreeWidget</a></span> fontTree;
fontTree<span class="operator">.</span>setColumnCount(<span class="number">2</span>);
fontTree<span class="operator">.</span>setHeaderLabels(<span class="type"><a href="qstringlist.html">QStringList</a></span>() <span class="operator"><</span><span class="operator"><</span> <span class="string">"Font"</span> <span class="operator"><</span><span class="operator"><</span> <span class="string">"Smooth Sizes"</span>);
foreach (<span class="keyword">const</span> <span class="type"><a href="qstring.html">QString</a></span> <span class="operator">&</span>family<span class="operator">,</span> database<span class="operator">.</span>families()) {

familyItem<span class="operator">-</span><span class="operator">></span>setText(<span class="number">0</span><span class="operator">,</span> family);
foreach (<span class="keyword">const</span> <span class="type"><a href="qstring.html">QString</a></span> <span class="operator">&</span>style<span class="operator">,</span> database<span class="operator">.</span>styles(family)) {
<span class="type"><a href="qtreewidgetitem.html">QTreeWidgetItem</a></span> <span class="operator">*</span>styleItem <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qtreewidgetitem.html">QTreeWidgetItem</a></span>(familyItem);
styleItem<span class="operator">-</span><span class="operator">></span>setText(<span class="number">0</span><span class="operator">,</span> style);
<span class="type"><a href="qstring.html">QString</a></span> sizes;
foreach (<span class="type">int</span> points<span class="operator">,</span> database<span class="operator">.</span>smoothSizes(family<span class="operator">,</span> style))
sizes <span class="operator">+</span><span class="operator">=</span> <span class="type"><a href="qstring.html">QString</a></span><span class="operator">.</span>number(points) <span class="operator">+</span> <span class="string">" "</span>;
styleItem<span class="operator">-</span><span class="operator">></span>setText(<span class="number">1</span><span class="operator">,</span> sizes<span class="operator">.</span>trimmed());
}
}
</pre>
<p>This example gets the list of font families, the list of styles
for each family, and the point sizes that are available for each
combination of family and style, displaying this information in a
tree view.</p>

Scaling a bitmap font usually produces an unattractive hardly
readable result, because the pixels of the font are scaled. If you

and the result will always look attractive.</p>
