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 QTextBlockFormat
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">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 <tt>OutlinePen</tt>, <tt>ForegroundBrush</tt>,
and <tt>BackgroundBrush</tt> <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>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="LineHeightTypes-enum" />QTextBlockFormat.LineHeightTypes</h3><p>This enum describes the various types of line spacing support
paragraphs can have.</p>
