<hr><a name="_details"></a><h2>Detailed Description</h2>
A PangoLayout C++ wrapper class.
<p>
The <a class="el" href="classGFC_1_1Pango_1_1Layout.html">Layout</a> object represents and entire paragraph of text. It is initialized with a <a class="el" href="classGFC_1_1Pango_1_1Context.html">Context</a>, UTF-8 string and a set of attributes for that string. Once that is done, the set of formatted lines can be extracted from the object, the layout can be rendered, and conversion between logical character positions within the layout's text, and the physical position of the resulting glyphs can be made.<p>
There are also a number of parameters to adjust the formatting of a <a class="el" href="classGFC_1_1Pango_1_1Layout.html">Layout</a>, which are illustrated in Figure 1. It is possible, as well, to ignore the 2-D setup, and simply treat the results of a <a class="el" href="classGFC_1_1Pango_1_1Layout.html">Layout</a> as a list of lines.<p>
<b>Figure 1:</b> Adjustable parameters for a <a class="el" href="classGFC_1_1Pango_1_1Layout.html">Layout</a>. <div align="center">
<img src="layout.png" alt="layout.png">
</div>
<p>
<br>
The <a class="el" href="classGFC_1_1Pango_1_1Layout.html">Layout</a> object provides a high-level driver for formatting entire paragraphs of text at once. While complete access to the layout capabilities of <a class="el" href="namespaceGFC_1_1Pango.html">Pango</a> is provided using the detailed interfaces for itemization and shaping, using that functionality directly involves writing a fairly large amount of code.<p>
<b>Note:</b> <layout.h> is the main <a class="el" href="namespaceGFC_1_1Pango.html">Pango</a> header file that your application will include, so for convenience, it includes all the required header files, except <break.h> (<a class="el" href="classGFC_1_1Pango_1_1LogAttr.html">LogAttr</a>) and <glyph.h> (<a class="el" href="classGFC_1_1Pango_1_1GlyphString.html">GlyphString</a>).

If the position count is positive, then the new strong cursor position will be one position to the right of the old cursor position.

Motion here is in cursor positions, not in characters, so a single call to <a class="el" href="classGFC_1_1Pango_1_1Layout.html#z1197_19">move_cursor_visually()</a> may move the cursor over multiple characters when multiple characters combine to form a single grapheme. </td>

Replaces the current text and attribute list. If accel_marker is nonzero, the given character will mark the character following it as an accelerator. For example, the accel marker might be an ampersand or underscore. All characters marked as an accelerator will receive a PANGO_UNDERLINE_LOW attribute, and the first character so marked will be returned in accel_char. Two accel_marker characters following each other produce a single literal accel_marker character. </td>
