In this case, +<a href="qfont.html#pointSize">QFont::pointSize</a>() returns 25 and <a href="#pointSize">QFontInfo::pointSize</a>() returns +24. +<p> There are three ways to create a QFontInfo object. +<ol type=1> +<li> Calling the QFontInfo constructor with a QFont creates a font +info object for a screen-compatible font, i.e. the font cannot be +a printer font<sup>*</sup>. If the font is changed later, the font +info object is <em>not</em> updated. +<p> <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 <em>not</em> +updated. +<p> <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 <em>not</em> updated. +</ol> +<p> <sup>*</sup> 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> <p>See also <a href="qfont.html">QFont</a>, <a href="qfontmetrics.html">QFontMetrics</a>, <a href="qfontdatabase.html">QFontDatabase</a>, <a href="graphics.html">Graphics Classes</a>, and <a href="shared.html">Implicitly and Explicitly Shared Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="QFontInfo"></a>QFontInfo::QFontInfo ( const <a href="qfont.html">QFont</a> & font ) +</h3> +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>, not <a href="qpicture.html">QPicture</a> or <a href="qprinter.html">QPrinter</a>. +<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> 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. + +<h3 class=fn><a name="QFontInfo-2"></a>QFontInfo::QFontInfo ( const <a href="qfont.html">QFont</a> & font, <a href="qfont.html#Script-enum">QFont::Script</a> script ) +</h3> +Constructs a font info object for <em>font</em> using the specified <em>script</em>. + +<h3 class=fn><a name="QFontInfo-3"></a>QFontInfo::QFontInfo ( const <a href="qfontinfo.html">QFontInfo</a> & fi ) +</h3> +Constructs a copy of <em>fi</em>. + +<h3 class=fn><a name="~QFontInfo"></a>QFontInfo::~QFontInfo () +</h3> +Destroys the font info object. + +<h3 class=fn>bool <a name="bold"></a>QFontInfo::bold () const +</h3> + +<p> Returns TRUE if <a href="#weight">weight</a>() would return a value greater than <a href="qfont.html#Weight-enum">QFont::Normal</a>;
