fonts.</p>
<p>The QFontInfo class provides the same access functions as
<a href="qfont.html">QFont</a>, e.g. <a href="qfontinfo.html#family">family</a>(), <a href="qfontinfo.html#pointSize">pointSize</a>(), <a href="qfontinfo.html#italic">italic</a>(), <a href="qfontinfo.html#weight">weight</a>(), <a href="qfontinfo.html#fixedPitch">fixedPitch</a>(), <a href="qfontinfo.html#styleHint">styleHint</a>() etc. But whilst the
<a href="qfont.html">QFont</a> access functions return the values
that were set, a QFontInfo object returns the values that apply to
the font that will actually be used to draw the text.</p>
<p>For example, when the program asks for a 25pt Courier font on a
machine that has a non-scalable 24pt Courier font, <a href="qfont.html">QFont</a> will (normally) use the 24pt Courier for
rendering. In this case, <a href="qfont.html#pointSize">QFont.pointSize</a>() returns 25 and
<a href="qfontinfo.html#pointSize">QFontInfo.pointSize</a>()
returns 24.</p>
<p>There are three ways to create a QFontInfo object.</p>
<ol class="1">
<li>Calling the QFontInfo constructor with a <a href="qfont.html">QFont</a> creates a font info object for a
screen-compatible font, i.e. the font cannot be a printer font. If
the font is changed later, the font info object is <i>not</i>
updated.
<p>(Note: If you use a printer font the values returned may be
inaccurate. Printer fonts are not always accessible so the nearest
screen font is used if a printer font is supplied.)</p>
</li>
<li><a href="qwidget.html#fontInfo">QWidget.fontInfo</a>() returns
the font info for a widget's font. This is equivalent to calling
QFontInfo(widget->font()). If the widget's font is changed
later, the font info object is <i>not</i> updated.</li>
<li><a href="qpainter.html#fontInfo">QPainter.fontInfo</a>()
returns the font info for a painter's current font. If the
painter's font is changed later, the font info object is <i>not</i>
updated.</li>
</ol>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QFontInfo" />QFontInfo.__init__ (<i>self</i>, <a href="qfont.html">QFont</a>)</h3><p>Constructs a font info object for <i>font</i>.</p>
<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>, not <a href="qpicture.html">QPicture</a> or <a href="qprinter.html">QPrinter</a>.</p>
<p>The font info object holds the information for the font that is
passed in the constructor at the time it is created, and is not
updated if the font's attributes are changed later.</p>
<p>Use <a href="qpainter.html#fontInfo">QPainter.fontInfo</a>() to
get the font info when painting. This will give correct results
also when painting on paint device that is not
screen-compatible.</p>
<h3 class="fn"><a name="QFontInfo-2" />QFontInfo.__init__ (<i>self</i>, <a href="qfontinfo.html">QFontInfo</a>)</h3><p>Constructs a copy of <i>fi</i>.</p>
<h3 class="fn"><a name="bold" />bool QFontInfo.bold (<i>self</i>)</h3><p>Returns true if <a href="qfontinfo.html#weight">weight</a>()
would return a value greater than <a href="qfont.html#Weight-enum">QFont.Normal</a>; otherwise returns
false.</p>
<p><b>See also</b> <a href="qfontinfo.html#weight">weight</a>() and
<a href="qfont.html#bold">QFont.bold</a>().</p>
<h3 class="fn"><a name="exactMatch" />bool QFontInfo.exactMatch (<i>self</i>)</h3><p>Returns true if the matched window system font is exactly the
same as the one specified by the font; otherwise returns false.</p>
<p><b>See also</b> <a href="qfont.html#exactMatch">QFont.exactMatch</a>().</p>
<h3 class="fn"><a name="family" />QString QFontInfo.family (<i>self</i>)</h3><p>Returns the family name of the matched window system font.</p>
<p><b>See also</b> <a href="qfont.html#family">QFont.family</a>().</p>
<h3 class="fn"><a name="fixedPitch" />bool QFontInfo.fixedPitch (<i>self</i>)</h3><p>Returns the fixed pitch value of the matched window system
font.</p>
<p><b>See also</b> <a href="qfont.html#fixedPitch">QFont.fixedPitch</a>().</p>
<h3 class="fn"><a name="italic" />bool QFontInfo.italic (<i>self</i>)</h3><p>Returns the italic value of the matched window system font.</p>
<p><b>See also</b> <a href="qfont.html#italic">QFont.italic</a>().</p>
<h3 class="fn"><a name="pixelSize" />int QFontInfo.pixelSize (<i>self</i>)</h3><p>Returns the pixel size of the matched window system font.</p>
<p><b>See also</b> <a href="qfont.html#pointSize">QFont.pointSize</a>().</p>
<h3 class="fn"><a name="pointSize" />int QFontInfo.pointSize (<i>self</i>)</h3><p>Returns the point size of the matched window system font.</p>
<p><b>See also</b> <a href="qfontinfo.html#pointSizeF">pointSizeF</a>() and <a href="qfont.html#pointSize">QFont.pointSize</a>().</p>
<h3 class="fn"><a name="pointSizeF" />float QFontInfo.pointSizeF (<i>self</i>)</h3><p>Returns the point size of the matched window system font.</p>
<p><b>See also</b> <a href="qfont.html#pointSizeF">QFont.pointSizeF</a>().</p>
<h3 class="fn"><a name="rawMode" />bool QFontInfo.rawMode (<i>self</i>)</h3><p>Returns true if the font is a raw mode font; otherwise returns
false.</p>
<p>If it is a raw mode font, all other functions in <a href="qfontinfo.html">QFontInfo</a> will return the same values set in
the <a href="qfont.html">QFont</a>, regardless of the font actually
used.</p>
<p><b>See also</b> <a href="qfont.html#rawMode">QFont.rawMode</a>().</p>
<h3 class="fn"><a name="style" /><a href="qfont.html#Style-enum">QFont.Style</a> QFontInfo.style (<i>self</i>)</h3><p>Returns the style value of the matched window system font.</p>
<p><b>See also</b> <a href="qfont.html#style">QFont.style</a>().</p>
<h3 class="fn"><a name="styleHint" /><a href="qfont.html#StyleHint-enum">QFont.StyleHint</a> QFontInfo.styleHint (<i>self</i>)</h3><p>Returns the style of the matched window system font.</p>
<p>Currently only returns the style hint set in <a href="qfont.html">QFont</a>.</p>
<p><b>See also</b> <a href="qfont.html#styleHint">QFont.styleHint</a>() and <a href="qfont.html#StyleHint-enum">QFont.StyleHint</a>.</p>
<h3 class="fn"><a name="styleName" />QString QFontInfo.styleName (<i>self</i>)</h3><p>Returns the style name of the matched window system font on
system that supports it.</p>
<p>This function was introduced in Qt 4.8.</p>
<p><b>See also</b> <a href="qfont.html#styleName">QFont.styleName</a>().</p>
<h3 class="fn"><a name="weight" />int QFontInfo.weight (<i>self</i>)</h3><p>Returns the weight of the matched window system font.</p>
<p><b>See also</b> <a href="qfont.html#weight">QFont.weight</a>()
and <a href="qfontinfo.html#bold">bold</a>().</p>
