<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qtextblockformat.html">QTextBlockFormat</a> class provides formatting information for blocks of text in a <a href="qtextdocument.html">QTextDocument</a>.</p>
<p>A document is composed of a list of blocks, represented by <a href="qtextblock.html">QTextBlock</a> objects. Each block can contain an item of some kind, such as a paragraph of text, a table, a list, or an image. Every block has an associated <a href="qtextblockformat.html">QTextBlockFormat</a> that specifies its characteristics.</p>
<p>To cater for left-to-right and right-to-left languages you can set a block's direction with setDirection(). Paragraph alignment is set with <a href="qtextblockformat.html#setAlignment">setAlignment</a>(). Margins are controlled by <a href="qtextblockformat.html#setTopMargin">setTopMargin</a>(), <a href="qtextblockformat.html#setBottomMargin">setBottomMargin</a>(), <a href="qtextblockformat.html#setLeftMargin">setLeftMargin</a>(), <a href="qtextblockformat.html#setRightMargin">setRightMargin</a>(). Overall indentation is set with <a href="qtextblockformat.html#setIndent">setIndent</a>(), the indentation of the first line with <a href="qtextblockformat.html#setTextIndent">setTextIndent</a>().</p>
<p>Line spacing is set with <a href="qtextblockformat.html#setLineHeight">setLineHeight</a>() and retrieved via <a href="qtextblockformat.html#lineHeight-1">lineHeight</a>() and <a href="qtextblockformat.html#lineHeightType">lineHeightType</a>(). The types of line spacing available are in the <a href="qtextblockformat.html#LineHeightTypes-enum">LineHeightTypes</a> enum.</p>
<p>Line breaking can be enabled and disabled with <a href="qtextblockformat.html#setNonBreakableLines">setNonBreakableLines</a>().</p>
<p>The brush used to paint the paragraph's background is set with <a href="qtextformat.html#setBackground">setBackground()</a>, and other aspects of the text's appearance can be customized by using the <a href="qtextformat.html#setProperty">setProperty()</a> function with the <code>OutlinePen</code>, <code>ForegroundBrush</code>, and <code>BackgroundBrush</code> <a href="qtextformat.html#Property-enum">QTextFormat::Property</a> values.</p>
<p>If a text block is part of a list, it can also have a list format that is accessible with the listFormat() function.</p>
