within a <a href="qtextdocument.html">QTextDocument</a>.</p>
<p>Block groups can be used to organize blocks of text within a
document. They maintain an up-to-date list of the text blocks that
belong to them, even when text blocks are being edited.</p>
<p>Each group has a parent document which is specified when the
group is constructed.</p>
<p>Text blocks can be inserted into a group with <a href="qtextblockgroup.html#blockInserted">blockInserted</a>(), and
removed with <a href="qtextblockgroup.html#blockRemoved">blockRemoved</a>(). If a
block's format is changed, <a href="qtextblockgroup.html#blockFormatChanged">blockFormatChanged</a>()
is called.</p>
<p>The list of blocks in the group is returned by <a href="qtextblockgroup.html#blockList">blockList</a>(). Note that the
blocks in the list are not necessarily adjacent elements in the
document; for example, the top-level items in a multi-level list
will be separated by the items in lower levels of the list.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QTextBlockGroup" />QTextBlockGroup.__init__ (<i>self</i>, <a href="qtextdocument.html">QTextDocument</a> <i>doc</i>)</h3><p>Creates a new new block group for the given <i>document</i>.</p>
<p><b>Warning:</b> This function should only be called from
<a href="qtextdocument.html#createObject">QTextDocument.createObject</a>().</p>
<h3 class="fn"><a name="blockFormatChanged" />QTextBlockGroup.blockFormatChanged (<i>self</i>, <a href="qtextblock.html">QTextBlock</a> <i>block</i>)</h3><p>This function is called whenever the specified <i>block</i> of
text is changed. The text block is a member of this group.</p>
<p>The base class implementation does nothing.</p>
<h3 class="fn"><a name="blockInserted" />QTextBlockGroup.blockInserted (<i>self</i>, <a href="qtextblock.html">QTextBlock</a> <i>block</i>)</h3><p>Appends the given <i>block</i> to the end of the group.</p>
<p><b>Warning:</b> If you reimplement this function you must call
the base class implementation.</p>
<h3 class="fn"><a name="blockList" />list-of-QTextBlock QTextBlockGroup.blockList (<i>self</i>)</h3><p>Returns a (possibly empty) list of all the blocks that are part
of the block group.</p>
<h3 class="fn"><a name="blockRemoved" />QTextBlockGroup.blockRemoved (<i>self</i>, <a href="qtextblock.html">QTextBlock</a> <i>block</i>)</h3><p>Removes the given <i>block</i> from the group; the block itself
is not deleted, it simply isn't a member of this group anymore.</p>
