<hr><a name="details"></a><h2>Detailed Description</h2>
The QFontDatabase class provides information about the fonts 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="#families">families</a>() and for the <a href="#pointSizes">pointSizes</a>() and <a href="#styles">styles</a>()
that are available for each family. An alternative to pointSizes()
is <a href="#smoothSizes">smoothSizes</a>() which returns the sizes at which a given family
and style will look attractive.
<p> If the font family is available from two or more foundries the
foundry name is included in the family name, e.g. "Helvetica
[Adobe]" and "Helvetica [Cronyx]". When you specify a family you
can either use the old hyphenated Qt 2.x "foundry-family" format,
e.g. "Cronyx-Helvetica", or the new bracketed Qt 3.x "family
[foundry]" format e.g. "Helvetica [Cronyx]". If the family has a
foundry it is always returned, e.g. by families(), using the
bracketed format.
<p> The <a href="#font">font</a>() function returns a <a href="qfont.html">QFont</a> given a family, style and
point size.
<p> A family and style combination can be checked to see if it is
<a href="#italic">italic</a>() or <a href="#bold">bold</a>(), and to retrieve its <a href="#weight">weight</a>(). Similarly we can
call <a href="#isBitmapScalable">isBitmapScalable</a>(), <a href="#isSmoothlyScalable">isSmoothlyScalable</a>(), <a href="#isScalable">isScalable</a>() and
<a href="#isFixedPitch">isFixedPitch</a>().
<p> A text version of a style is given by <a href="#styleString">styleString</a>().
<p> The QFontDatabase class also supports some static functions, for
example, <a href="#standardSizes">standardSizes</a>(). You can retrieve the Unicode 3.0
description of a <a href="qfont.html#Script-enum">script</a> using
<a href="#scriptName">scriptName</a>(), and a sample of characters in a script with
<a href="#scriptSample">scriptSample</a>().
<p> Example:
<pre>
#include <<a href="qapplication-h.html">qapplication.h</a>>
#include <<a href="qfontdatabase-h.html">qfontdatabase.h</a>>
#include <else.h>
int main( int argc, char **argv )
{
<a href="qapplication.html">QApplication</a> app( argc, argv );
QFontDatabase fdb;
<a href="qstringlist.html">QStringList</a> families = fdb.<a href="#families">families</a>();
for ( QStringList::Iterator f = families.<a href="qvaluelist.html#begin">begin</a>(); f != families.<a href="qvaluelist.html#end">end</a>(); ++f ) {
<a href="qstring.html">QString</a> family = *f;
<a href="qapplication.html#qDebug">qDebug</a>( family );
<a href="qstringlist.html">QStringList</a> styles = fdb.<a href="#styles">styles</a>( family );
for ( QStringList::Iterator s = styles.<a href="qvaluelist.html#begin">begin</a>(); s != styles.<a href="qvaluelist.html#end">end</a>(); ++s ) {
<a href="qstring.html">QString</a> style = *s;
<a href="qstring.html">QString</a> dstyle = "\t" + style + " (";
<a href="qvaluelist.html">QValueList</a><int> smoothies = fdb.<a href="#smoothSizes">smoothSizes</a>( family, style );
for ( QValueList<int>::Iterator points = smoothies.<a href="qvaluelist.html#begin">begin</a>();
points != smoothies.<a href="qvaluelist.html#end">end</a>(); ++points ) {
dstyle += QString::<a href="qstring.html#number">number</a>( *points ) + " ";
}
dstyle = dstyle.<a href="qstring.html#left">left</a>( dstyle.<a href="qstring.html#length">length</a>() - 1 ) + ")";
<a href="qapplication.html#qDebug">qDebug</a>( dstyle );
}
}
return 0;
}
</pre>
This example gets the list of font families, then the list of
styles for each family and the point sizes that are available for
each family/style combination.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QFontDatabase"></a>QFontDatabase::QFontDatabase ()
</h3>
Creates a font database object.
<h3 class=fn>bool <a name="bold"></a>QFontDatabase::bold ( const <a href="qstring.html">QString</a> & family, const <a href="qstring.html">QString</a> & style ) const
</h3>
Returns TRUE if the font that has family <em>family</em> and style <em>style</em> is bold; otherwise returns FALSE.
<p> <p>See also <a href="#italic">italic</a>() and <a href="#weight">weight</a>().
<h3 class=fn>bool <a name="bold-2"></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> & ) const
</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>
<h3 class=fn><a href="qstringlist.html">QStringList</a> <a name="families"></a>QFontDatabase::families () const
</h3> Returns a sorted list of the names of the available font families.
<p> If a family exists in several foundries, the returned name for
that font is in the form "family [foundry]". Examples: "Times
[Adobe]", "Times [Cronyx]", "Palatino".
<h3 class=fn><a href="qstringlist.html">QStringList</a> <a name="families-2"></a>QFontDatabase::families ( <a href="qfont.html#Script-enum">QFont::Script</a> script ) const
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Returns a sorted list of the available font families which support
the Unicode script <em>script</em>.
<p> If a family exists in several foundries, the returned name for
that font is in the form "family [foundry]". Examples: "Times
[Adobe]", "Times [Cronyx]", "Palatino".
<h3 class=fn><a href="qstringlist.html">QStringList</a> <a name="families-3"></a>QFontDatabase::families ( bool ) const
</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>
<h3 class=fn><a href="qfont.html">QFont</a> <a name="font"></a>QFontDatabase::font ( const <a href="qstring.html">QString</a> & family, const <a href="qstring.html">QString</a> & style, int pointSize )
</h3>
Returns a <a href="qfont.html">QFont</a> object that has family <em>family</em>, style <em>style</em>
and point size <em>pointSize</em>. If no matching font could be created,
a QFont object that uses the application's default font is
returned.
<h3 class=fn><a href="qfont.html">QFont</a> <a name="font-2"></a>QFontDatabase::font ( const <a href="qstring.html">QString</a> & familyName, const <a href="qstring.html">QString</a> & style, int pointSize, const <a href="qstring.html">QString</a> & )

</h3>
Returns TRUE if the font that has family <em>family</em> and style <em>style</em> is a scalable bitmap font; otherwise returns FALSE. Scaling
a bitmap font usually produces an unattractive hardly readable
result, because the pixels of the font are scaled. If you need to
scale a bitmap font it is better to scale it to one of the fixed
sizes returned by <a href="#smoothSizes">smoothSizes</a>().

</h3>
