<h2>Detailed Description</h2>
<p>The QPlainTextDocumentLayout class implements a plain text layout for <a href="qtextdocument.html">QTextDocument</a></p>
<p>A QPlainTextDocumentLayout is required for text documents that can be display or edited in a <a href="qplaintextedit.html">QPlainTextEdit</a>. See <a href="qtextdocument.html#setDocumentLayout">QTextDocument::setDocumentLayout</a>().</p>
<p>QPlainTextDocumentLayout uses the <a href="qabstracttextdocumentlayout.html">QAbstractTextDocumentLayout</a> API that <a href="qtextdocument.html">QTextDocument</a> requires, but redefines it partially in order to support plain text better. For instances, it does not operate on vertical pixels, but on paragraphs (called blocks) instead. The height of a document is identical to the number of paragraphs it contains. The layout also doesn't support tables or nested frames, or any sort of advanced text layout that goes beyond a list of paragraphs with syntax highlighting.</p>
