<!-- $$$QStackedLayout-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QStackedLayout class provides a stack of widgets where only one widget is visible at a time.</p>
<p>QStackedLayout can be used to create a user interface similar to the one provided by <a href="qtabwidget.html">QTabWidget</a>. There is also a convenience <a href="qstackedwidget.html">QStackedWidget</a> class built on top of QStackedLayout.</p>
<p>A QStackedLayout can be populated with a number of child widgets ("pages"). For example:</p>
<pre class="cpp"> <span class="type"><a href="qwidget.html">QWidget</a></span> <span class="operator">*</span>firstPageWidget <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qwidget.html">QWidget</a></span>;
<span class="type"><a href="qwidget.html">QWidget</a></span> <span class="operator">*</span>secondPageWidget <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qwidget.html">QWidget</a></span>;
<span class="type"><a href="qwidget.html">QWidget</a></span> <span class="operator">*</span>thirdPageWidget <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qwidget.html">QWidget</a></span>;
<span class="type">QStackedLayout</span> <span class="operator">*</span>stackedLayout <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QStackedLayout</span>;
stackedLayout<span class="operator">-</span><span class="operator">></span>addWidget(firstPageWidget);
stackedLayout<span class="operator">-</span><span class="operator">></span>addWidget(secondPageWidget);
stackedLayout<span class="operator">-</span><span class="operator">></span>addWidget(thirdPageWidget);
<span class="type"><a href="qvboxlayout.html">QVBoxLayout</a></span> <span class="operator">*</span>mainLayout <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qvboxlayout.html">QVBoxLayout</a></span>;
mainLayout<span class="operator">-</span><span class="operator">></span>addLayout(stackedLayout);
setLayout(mainLayout);</pre>
<p>QStackedLayout provides no intrinsic means for the user to switch page. This is typically done through a <a href="qcombobox.html">QComboBox</a> or a <a href="qlistwidget.html">QListWidget</a> that stores the titles of the QStackedLayout's pages. For example:</p>
<pre class="cpp"> <span class="type"><a href="qcombobox.html">QComboBox</a></span> <span class="operator">*</span>pageComboBox <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qcombobox.html">QComboBox</a></span>;
pageComboBox<span class="operator">-</span><span class="operator">></span>addItem(tr(<span class="string">"Page 1"</span>));
pageComboBox<span class="operator">-</span><span class="operator">></span>addItem(tr(<span class="string">"Page 2"</span>));
pageComboBox<span class="operator">-</span><span class="operator">></span>addItem(tr(<span class="string">"Page 3"</span>));
connect(pageComboBox<span class="operator">,</span> SIGNAL(activated(<span class="type">int</span>))<span class="operator">,</span>
stackedLayout<span class="operator">,</span> SLOT(setCurrentIndex(<span class="type">int</span>)));</pre>
<p>When populating a layout, the widgets are added to an internal list. The <a href="qlayout.html#indexOf">indexOf</a>() function returns the index of a widget in that list. The widgets can either be added to the end of the list using the <a href="qstackedlayout.html#addWidget">addWidget</a>() function, or inserted at a given index using the <a href="qstackedlayout.html#insertWidget">insertWidget</a>() function. The <a href="qlayout.html#removeWidget">removeWidget</a>() function removes the widget at the given index from the layout. The number of widgets contained in the layout, can be obtained using the <a href="qstackedlayout.html#count-prop">count</a>() function.</p>
<p>The <a href="qstackedlayout.html#widget">widget</a>() function returns the widget at a given index position. The index of the widget that is shown on screen is given by <a href="qstackedlayout.html#currentIndex-prop">currentIndex</a>() and can be changed using <a href="qstackedlayout.html#currentIndex-prop">setCurrentIndex</a>(). In a similar manner, the currently shown widget can be retrieved using the <a href="qstackedlayout.html#currentWidget">currentWidget</a>() function, and altered using the <a href="qstackedlayout.html#setCurrentWidget">setCurrentWidget</a>() function.</p>
<p>Whenever the current widget in the layout changes or a widget is removed from the layout, the <a href="qstackedlayout.html#currentChanged">currentChanged</a>() and <a href="qstackedlayout.html#widgetRemoved">widgetRemoved</a>() signals are emitted respectively.</p>
