<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qhistorystate.html">QHistoryState</a> class provides a means of returning to a previously active substate.</p>
<p>A history state is a pseudo-state that represents the child state that the parent state was in the last time the parent state was exited. A transition with a history state as its target is in fact a transition to one or more other child states of the parent state. <a href="qhistorystate.html">QHistoryState</a> is part of <a href="statemachine-api.html">The State Machine Framework</a>.</p>
<p>Use the <a href="qhistorystate.html#setDefaultState">setDefaultState</a>() function to set the state that should be entered if the parent state has never been entered. Example:</p>
<pre class="cpp">
<span class="type"><a href="qstatemachine.html">QStateMachine</a></span> machine;
<span class="type"><a href="qstate.html">QState</a></span> <span class="operator">*</span>s1 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qstate.html">QState</a></span>();

machine<span class="operator">.</span>addState(s1);
<span class="type"><a href="qstate.html">QState</a></span> <span class="operator">*</span>s2 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qstate.html">QState</a></span>();
machine<span class="operator">.</span>addState(s2);
<span class="type"><a href="../qtwidgets/qpushbutton.html">QPushButton</a></span> <span class="operator">*</span>button <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="../qtwidgets/qpushbutton.html">QPushButton</a></span>();
<span class="comment">// Clicking the button will cause the state machine to enter the child state</span>
<span class="comment">// that s1 was in the last time s1 was exited, or the history state's default</span>
<span class="comment">// state if s1 has never been entered.</span>
s1<span class="operator">-</span><span class="operator">></span>addTransition(button<span class="operator">,</span> SIGNAL(clicked())<span class="operator">,</span> s1h);
</pre>
<p>If more than one default state has to be entered, or if the transition to the default state(s) has to be acted upon, the <a href="qhistorystate.html#defaultTransition-prop">defaultTransition</a> should be set instead. Note that the eventTest() method of that transition will never be called: the selection and execution of the transition is done automatically when entering the history state.</p>
<p>By default a history state is shallow, meaning that it won't remember nested states. This can be configured through the <a href="qhistorystate.html#historyType-prop">historyType</a> property.</p>
