<hr><h2><a name="details"></a>Detailed Description</h2>
Provides information about available fonts.
<p>
QFontDatabase provides information about the available fonts of the
underlying window system.
<p>Most often you will simply want to query the database for all font
<a href="#4cec70">families</a>(), and their respective <a href="#00d369">pointSizes</a>(), <a href="#c45b15">styles</a>() and
<a href="#6c428e">charSets</a>().
<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="a5138b"></a>QFontDatabase::QFontDatabase()</h3>
<p>Creates a font database object.
<h3 class="fn">bool<a name="25a4e9"></a>QFontDatabase::bold(const<a href="qstring.html">QString</a>&family, const<a href="qstring.html">QString</a>&style, const<a href="qstring.html">QString</a>&charSet=QString::null)const</h3>
<p>Returns if the font which matches the settings <em>family, style</em> and
<em>charSet</em> is bold or not.
<p>See also <a href="#074127">italic</a>() and <a href="#6005f9">weight</a>().
<h3 class="fn"><a href="qstring.html">QString</a><a name="d20be2"></a>QFontDatabase::charSetSample(const<a href="qstring.html">QString</a>&charSetName) <code>[static]</code></h3>
<p>Returns some sample characters which are in the charset <em>charSetName.</em>
<h3 class="fn"><a href="qstringlist.html">QStringList</a><a name="6c428e"></a>QFontDatabase::charSets(const<a href="qstring.html">QString</a>&family, boolonlyForLocale=TRUE)const</h3>
<p>Returns a list of all char sets in which the font <em>family</em> is available in the
current locale if <em>onlyForLocale</em> is TRUE, otherwise all charsets of <em>family</em>
independent of the locale are returned.
<h3 class="fn"><a href="qstringlist.html">QStringList</a><a name="4cec70"></a>QFontDatabase::families(boolonlyForLocale=TRUE)const</h3>
<p>Returns a list of names of all available font families in the current locale if
<em>onlyForLocale</em> is TRUE, otherwise really all available font families independent
of the current locale are returned.
<p>If a family exists in several foundries, the returned name will be "foundry-family".
<h3 class="fn"><a href="qfont.html">QFont</a><a name="30ea99"></a>QFontDatabase::font(const<a href="qstring.html">QString</a>family, const<a href="qstring.html">QString</a>&style, intpointSize, const<a href="qstring.html">QString</a>charSet=QString::null)</h3>
<p>Returns a <a href="qfont.html">QFont</a> object which matches the settings of <em>family, style, pointsize</em> and <em>charSet.</em> If no matching font could be created
an empty QFont object is returned.
<h3 class="fn">bool<a name="ae12c2"></a>QFontDatabase::isBitmapScalable(const<a href="qstring.html">QString</a>&family, const<a href="qstring.html">QString</a>&style=QString::null, const<a href="qstring.html">QString</a>&charSet=QString::null)const</h3>
<p>Returns whether the font which matches <em>family, style</em> and <em>charSet</em> is
a scaleable bitmap font. Scaling a bitmap font produces a bad, often hardly
readable result, as the pixels of the font are scaled. It's better to scale such
a font only to the available fixed sizes (which you can get with <a href="#14e456">smoothSizes</a>()).
<p>See also <a href="#e01948">isScalable</a>() and <a href="#72207a">isSmoothlyScalable</a>().
<h3 class="fn">bool<a name="e03ae8"></a>QFontDatabase::isFixedPitch(const<a href="qstring.html">QString</a>&family, const<a href="qstring.html">QString</a>&style=QString::null, const<a href="qstring.html">QString</a>&charSet=QString::null)const</h3>
<p>Returns whether the font which matches <em>family, style</em> and <em>charSet</em> is
fixed pitch.
<h3 class="fn">bool<a name="e01948"></a>QFontDatabase::isScalable(const<a href="qstring.html">QString</a>&family, const<a href="qstring.html">QString</a>&style=QString::null, const<a href="qstring.html">QString</a>&charSet=QString::null)const</h3>
<p>Returns TRUE if the font which matches the settings <em>family, style</em> and <em>charSet</em>
is scaleable.
<p>See also <a href="#ae12c2">isBitmapScalable</a>() and <a href="#72207a">isSmoothlyScalable</a>().
<h3 class="fn">bool<a name="72207a"></a>QFontDatabase::isSmoothlyScalable(const<a href="qstring.html">QString</a>&family, const<a href="qstring.html">QString</a>&style=QString::null, const<a href="qstring.html">QString</a>&charSet=QString::null)const</h3>
<p>Returns whether the font which matches <em>family, style</em> and <em>charSet</em> is
a smoothly scaleable. If this function returns TRUE, it's save to scale this font
to every size as the result will always look good.
<p>See also <a href="#e01948">isScalable</a>() and <a href="#ae12c2">isBitmapScalable</a>().
<h3 class="fn">bool<a name="074127"></a>QFontDatabase::italic(const<a href="qstring.html">QString</a>&family, const<a href="qstring.html">QString</a>&style, const<a href="qstring.html">QString</a>&charSet=QString::null)const</h3>
<p>Returns if the font which matches the settings <em>family, style</em> and
<em>charSet</em> is italic or not.
<p>See also <a href="#6005f9">weight</a>() and <a href="#25a4e9">bold</a>().
<h3 class="fn"><a href="qvaluelist.html">QValueList</a><int><a name="00d369"></a>QFontDatabase::pointSizes(const<a href="qstring.html">QString</a>&family, const<a href="qstring.html">QString</a>&style=QString::null, const<a href="qstring.html">QString</a>&charSet=QString::null)</h3>
<p>Returns a list of all available sizes of the font <em>family</em> in the
style <em>style</em> and the char set <em>charSet.</em>
<p>See also <a href="#14e456">smoothSizes</a>() and <a href="#dbeea8">standardSizes</a>().
<h3 class="fn"><a href="qvaluelist.html">QValueList</a><int><a name="14e456"></a>QFontDatabase::smoothSizes(const<a href="qstring.html">QString</a>&family, const<a href="qstring.html">QString</a>&style, const<a href="qstring.html">QString</a>&charSet=QString::null)</h3>
<p>Returns the point sizes of a font which matches <em>family, style</em> and <em>charSet,</em>
that is guaranteed to look good. For non-scalable fonts and smoothly scalable fonts this function
is equivalent to <a href="#00d369">pointSizes</a>().
<p>See also <a href="#00d369">pointSizes</a>() and <a href="#dbeea8">standardSizes</a>().
<h3 class="fn"><a href="qvaluelist.html">QValueList</a><int><a name="dbeea8"></a>QFontDatabase::standardSizes() <code>[static]</code></h3>
<p>Returns a list of standard fontsizes.
<p>See also <a href="#14e456">smoothSizes</a>() and <a href="#00d369">pointSizes</a>().
<h3 class="fn"><a href="qstring.html">QString</a><a name="6a1e1f"></a>QFontDatabase::styleString(const<a href="qfont.html">QFont</a>&f)</h3>
<p>Returns a string with describes the style of the font <em>f.</em> This is Something like
"Bold Italic".
<h3 class="fn"><a href="qstringlist.html">QStringList</a><a name="c45b15"></a>QFontDatabase::styles(const<a href="qstring.html">QString</a>&family, const<a href="qstring.html">QString</a>&charSet=QString::null)const</h3>
<p>Retruns all available styles of the font <em>family</em> in the
char set <em>charSet.</em>
<h3 class="fn"><a href="qstring.html">QString</a><a name="f263a1"></a>QFontDatabase::verboseCharSetName(const<a href="qstring.html">QString</a>&charSetName) <code>[static]</code></h3>
<p>Returns a string which gives a quite detailed description of the <em>charSetName</em>
which can be used e.g. for displaying in a dialog for the user.
<h3 class="fn">int<a name="6005f9"></a>QFontDatabase::weight(const<a href="qstring.html">QString</a>&family, const<a href="qstring.html">QString</a>&style, const<a href="qstring.html">QString</a>&charSet=QString::null)const</h3>
<p>Returns the weight of the font which matches the settings <em>family, style</em> and
<em>charSet.</em>
