<hr><h2><a name="details"></a>Detailed Description</h2>
The QFontInfo class provides general information about fonts.
<p>
The QFontInfo class mirrors <a href="qfont.html">QFont</a> exactly, but where QFont access
functions return set values, QFontInfo returns the values that
apply to the font in use.
<p>For example, when the program asks for a 25pt Courier font on a
machine that has a 24pt Courier font but not a scalable one, QFont
will (normally) use the 24pt Courier for rendering.  In this case,
<a href="qfont.html#46f238">QFont::pointSize</a>() returns 25 and <a href="#391046">QFontInfo::pointSize</a>() 24.
<p>The access functions in QFontInfo mirror QFont exactly, except for
this difference.
<p>There are three ways to create a QFontInfo object.
<p>The QFontInfo constructor with a QFont creates a font info object
for a screen-compatible font, i.e. the font can not be a printer
font.
<p><a href="qwidget.html#205244">QWidget::fontInfo</a>() returns the font info for a widget's font.  This
is equivalent to QFontInfo(widget->font()).  Setting a new font for
the widget later does not affect the font info object.
<p><a href="qpainter.html#5bdc93">QPainter::fontInfo</a>() returns the font info for a painter's current
font. The font info object is automatically updated if somebody sets
a new painter font, unlike the two above cases, which take a
"snapshot" of a font.
<p>See also  <a href="qfont.html">QFont</a> and <a href="qfontmetrics.html">QFontMetrics</a>.

<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="86a9c9"></a>QFontInfo::QFontInfo(const<a href="qfont.html">QFont</a>&amp;font)</h3>
<p>Constructs a font info object for <em>font.</em>
<p>The font must be screen-compatible, i.e. a font you use when drawing
text in <a href="qwidget.html">widgets</a> or <a href="qpixmap.html">pixmaps</a>.
If <em>font</em> is a printer font, you'll probably get wrong results.
<p>Use the <a href="qpainter.html#5bdc93">QPainter::fontInfo</a>() to get the font info when painting.
This is a little slower than using this constructor, but it always
gives correct results.
<h3 class="fn"><a name="06ae58"></a>QFontInfo::QFontInfo(constQFontInfo&amp;fi)</h3>
<p>Constructs a copy of <em>fi.</em>
<h3 class="fn"><a name="143e45"></a>QFontInfo::~QFontInfo()</h3>
<p>Destructs the font info object.
<h3 class="fn">bool<a name="85b956"></a>QFontInfo::bold()const</h3>
<p>Returns TRUE if <a href="#f6d443">weight</a>() would return a greater than
<code>QFont::Normal,</code> and FALSE otherwise.
<p>See also  <a href="#f6d443">weight</a>() and <a href="qfont.html#30083e">QFont::bold</a>().
<h3 class="fn">QFont::CharSet<a name="0638f2"></a>QFontInfo::charSet()const</h3>
<p>Returns the character set of the matched window system font.
<p>See also  <a href="qfont.html#dec730">QFont::charSet</a>().
<h3 class="fn">bool<a name="9e539b"></a>QFontInfo::exactMatch()const</h3>
<p>Returns TRUE if the matched window system font is exactly the one specified
by the font.
<p>See also  <a href="qfont.html#5423b2">QFont::exactMatch</a>().
<h3 class="fn"><a href="qstring.html">QString</a><a name="643714"></a>QFontInfo::family()const</h3>
<p>Returns the family name of the matched window system font.
<p>See also  <a href="qfont.html#cb6c0d">QFont::family</a>().
<h3 class="fn">bool<a name="b0ce63"></a>QFontInfo::fixedPitch()const</h3>
<p>Returns the fixed pitch value of the matched window system font.
A fixed pitch font is a font that has constant character pixel width.
<p>See also  <a href="qfont.html#f13eeb">QFont::fixedPitch</a>().
<h3 class="fn">bool<a name="1d0fa7"></a>QFontInfo::italic()const</h3>
<p>Returns the italic value of the matched window system font.
<p>See also  <a href="qfont.html#b38bfa">QFont::italic</a>().
<h3 class="fn">QFontInfo&amp;<a name="b52b98"></a>QFontInfo::operator=(constQFontInfo&amp;fi)</h3>
<p>Font info assignment.
<h3 class="fn">int<a name="391046"></a>QFontInfo::pointSize()const</h3>
<p>Returns the point size of the matched window system font.
<p>See also  <a href="qfont.html#46f238">QFont::pointSize</a>().
<h3 class="fn">bool<a name="5829d5"></a>QFontInfo::rawMode()const</h3>
<p>Returns TRUE if the font is a raw mode font.
<p>If it is a raw mode font, all other functions in QFontInfo will return the
same values set in the <a href="qfont.html">QFont</a>, regardless of the font actually used.
<p>See also  <a href="qfont.html#95a609">QFont::rawMode</a>().
<h3 class="fn">bool<a name="48aaca"></a>QFontInfo::strikeOut()const</h3>
<p>Returns the strike out value of the matched window system font.
<p>See also  <a href="qfont.html#d8d538">QFont::strikeOut</a>().
<h3 class="fn">QFont::StyleHint<a name="8ae0b9"></a>QFontInfo::styleHint()const</h3>
<p>Returns the style of the matched window system font.
<p>Currently only returns the hint set in <a href="qfont.html">QFont</a>.
<p>See also  <a href="qfont.html#634c0c">QFont::styleHint</a>().
<h3 class="fn">bool<a name="38ad03"></a>QFontInfo::underline()const</h3>
<p>Returns the underline value of the matched window system font.
<p>See also  <a href="qfont.html#34e94b">QFont::underline</a>().
<h3 class="fn">int<a name="f6d443"></a>QFontInfo::weight()const</h3>
<p>Returns the weight of the matched window system font.
<p>See also  <a href="qfont.html#41db89">QFont::weight</a>() and <a href="#85b956">bold</a>().
