<p>A list contains a sequence of text blocks, each of which is marked with a bullet point or other symbol. Multiple levels of lists can be used, and the automatic numbering feature provides support for ordered numeric and alphabetical lists.</p>
<p>Lists are created by using a text cursor to insert an empty list at the current position or by moving existing text into a new list. The <a href="qtextcursor.html#insertList">QTextCursor.insertList</a>() function inserts an empty block into the document at the cursor position, and makes it the first item in a list.</p>
<pre> QTextListFormat listFormat;
if (list) {
listFormat = list->format();
listFormat.setIndent(listFormat.indent() + 1);
}
listFormat.setStyle(QTextListFormat.ListDisc);
cursor.insertList(listFormat);</pre>
<p>The <a href="qtextcursor.html#createList">QTextCursor.createList</a>() function takes the contents of the cursor's current block and turns it into the first item of a new list.</p>
<p>The cursor's current list is found with <a href="qtextcursor.html#currentList">QTextCursor.currentList</a>().</p>
<p>The number of items in a list is given by <a href="qtextlist.html#count">count</a>(). Each item can be obtained by its index in the list with the <a href="qtextlist.html#item">item</a>() function. Similarly, the index of a given item can be found with <a href="qtextlist.html#itemNumber">itemNumber</a>(). The text of each item can be found with the <a href="qtextlist.html#itemText">itemText</a>() function.</p>
<p>Note that the items in the list may not be 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>
<p>List items can be deleted by index with the <a href="qtextlist.html#removeItem">removeItem</a>() function. <a href="qtextlist.html#remove">remove</a>() deletes the specified item in the list.</p>
<p>The list's format is set with <a href="qtextlist.html#setFormat">setFormat</a>() and read with <a href="qtextlist.html#format">format</a>(). The format describes the decoration of the list itself, and not the individual items.</p>
