<h2>Detailed Description</h2>
<p>The QUndoView class displays the contents of a <a href="qundostack.html">QUndoStack</a>.</p>
<p>QUndoView is a <a href="qlistview.html">QListView</a> which displays the list of commands pushed on an undo stack. The most recently executed command is always selected. Selecting a different command results in a call to <a href="qundostack.html#setIndex">QUndoStack::setIndex</a>(), rolling the state of the document backwards or forward to the new command.</p>
<p>The stack can be set explicitly with <a href="qundoview.html#setStack">setStack</a>(). Alternatively, a <a href="qundogroup.html">QUndoGroup</a> object can be set with <a href="qundoview.html#setGroup">setGroup</a>(). The view will then update itself automatically whenever the active stack of the group changes.</p>

<h3 class="fn"><a name="cleanIcon-prop"></a><span class="name">cleanIcon</span> : <span class="type"><a href="qicon.html">QIcon</a></span></h3>
<p>This property holds the icon used to represent the clean state.</p>
<p>A stack may have a clean state set with <a href="qundostack.html#setClean">QUndoStack::setClean</a>(). This is usually the state of the document at the point it was saved. <a href="qundoview.html">QUndoView</a> can display an icon in the list of commands to show the clean state. If this property is a null icon, no icon is shown. The default value is the null icon.</p>
