<hr><a name="_details"></a><h2>Detailed Description</h2>
A PangoFontset C++ wrapper class.
<p>
A <a class="el" href="classGFC_1_1Pango_1_1Fontset.html">Fontset</a> represents a set of <a class="el" href="classGFC_1_1Pango_1_1Font.html">Font</a> to use when rendering text. It is the result of resolving a <a class="el" href="classGFC_1_1Pango_1_1FontDescription.html">FontDescription</a> against a particular <a class="el" href="classGFC_1_1Pango_1_1Context.html">Context</a>. It has operations for finding the component font for a particular Unicode character, and for finding a composite set of metrics for the entire fontset.
