<p>
Sets the layout text and attribute list from marked-up text (see
<a href="PangoMarkupFormat.html" title="Text Attribute Markup">markup format</a>). Replaces
the current text and attribute list.
</p>
<p>
If <em class="parameter"><code>accel_marker</code></em> is nonzero, the given character will mark the
character following it as an accelerator. For example, <em class="parameter"><code>accel_marker</code></em>
might be an ampersand or underscore. All characters marked
as an accelerator will receive a <a href="pango-Text-Attributes.html#PANGO-UNDERLINE-LOW:CAPS"><code class="literal">PANGO_UNDERLINE_LOW</code></a> attribute,
and the first character so marked will be returned in <em class="parameter"><code>accel_char</code></em>.
Two <em class="parameter"><code>accel_marker</code></em> characters following each other produce a single
literal <em class="parameter"><code>accel_marker</code></em> character.</p>
