A PangoItem C++ wrapper class. 
<p>
<a class="el" href="classGFC_1_1Pango_1_1Item.html">Item</a> is an object that stores information about a segment of text. You can obtain an <a class="el" href="classGFC_1_1Pango_1_1Item.html">Item</a> by calling <a class="el" href="classGFC_1_1Pango_1_1Context.html#z1149_6">Pango::Context::itemize()</a> which returns a vector of Pointer&lt;Item&gt;.

You can think of <em>split_index</em> as the length of the returned item. <em>split_index</em> may not be 0, and it may not be greater than or equal to the length this item before the split (that is, there must be at least one byte assigned to each item, you can't create a zero-length item). <em>split_offset</em> is the length chars of the first (returned) item, and must be provided because the text used to generate the item isn't available, so <a class="el" href="classGFC_1_1Pango_1_1Item.html#z1186_0">split()</a> can't count the character length of the split items itself.     </td>
