<h2 id="details">Detailed Description</h2>
<p>The <a href="qml-qtqml-statemachine-qabstracttransition.html">QAbstractTransition</a> type is the abstract base type of transitions between states (<a href="qml-qtqml-statemachine-qabstractstate.html">QAbstractState</a> objects) of a <a href="qml-qtqml-statemachine-statemachine.html">StateMachine</a>. <a href="qml-qtqml-statemachine-qabstracttransition.html">QAbstractTransition</a> is part of <a href="qmlstatemachine.html">The Declarative State Machine Framework</a>.</p>
<p>The sourceState() property has the source of the transition. The <a href="qml-qtqml-statemachine-qabstracttransition.html#targetState-prop">targetState</a> and <a href="qml-qtqml-statemachine-qabstracttransition.html#targetStates-prop">targetStates</a> properties return the target(s) of the transition.</p>
<p>The <a href="qml-qtqml-statemachine-qabstracttransition.html#triggered-signal">triggered()</a> signal is emitted when the transition has been triggered.</p>
<p>Do not use <a href="qml-qtqml-statemachine-qabstracttransition.html">QAbstractTransition</a> directly; use <a href="qml-qtqml-statemachine-signaltransition.html">SignalTransition</a> or <a href="qml-qtqml-statemachine-timeouttransition.html">TimeoutTransition</a> instead.</p>
