<p>The QTextBlockGroup class provides a container for text blocks 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> </div> <p><b>See also </b><a href="qtextblock.html">QTextBlock</a> and <a href="qtextdocument.html">QTextDocument</a>.</p> <!-- @@@QTextBlockGroup --> <div class="func"> <h2>Member Function Documentation</h2> <!-- $$$QTextBlockGroup[overload1]$$$QTextBlockGroupQTextDocument* --> <h3 class="fn"><a name="QTextBlockGroup"></a>QTextBlockGroup::<span class="name">QTextBlockGroup</span> ( <span class="type"><a href="qtextdocument.html">QTextDocument</a></span> * <i>document</i> )<tt> [protected]</tt></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> <!-- @@@QTextBlockGroup --> <!-- $$$~QTextBlockGroup[overload1]$$$~QTextBlockGroup --> <h3 class="fn"><a name="dtor.QTextBlockGroup"></a>QTextBlockGroup::<span class="name">~QTextBlockGroup</span> ()<tt> [protected]</tt></h3> <p>Destroys this block group; the blocks are not deleted, they simply don't belong to this block anymore.</p> <!-- @@@~QTextBlockGroup --> <!-- $$$blockFormatChanged[overload1]$$$blockFormatChangedconstQTextBlock& --> <h3 class="fn"><a name="blockFormatChanged"></a><span class="type">void</span> QTextBlockGroup::<span class="name">blockFormatChanged</span> ( const <span class="type"><a href="qtextblock.html">QTextBlock</a></span> & <i>block</i> )<tt> [virtual protected]</tt></h3> <p>This function is called whenever the specified <i>block</i> of text is changed.
