<!-- $$$QAbstractItemView-description -->
<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qabstractitemview.html">QAbstractItemView</a> class provides the basic functionality for item view classes.</p>
<p><a href="qabstractitemview.html">QAbstractItemView</a> class is the base class for every standard view that uses a <a href="../qtcore/qabstractitemmodel.html">QAbstractItemModel</a>. <a href="qabstractitemview.html">QAbstractItemView</a> is an abstract class and cannot itself be instantiated. It provides a standard interface for interoperating with models through the signals and slots mechanism, enabling subclasses to be kept up-to-date with changes to their models. This class provides standard support for keyboard and mouse navigation, viewport scrolling, item editing, and selections. The keyboard navigation implements this functionality:</p>
<div class="table"><table class="generic">
<thead><tr class="qt-style"><th >Keys</th><th >Functionality</th></tr></thead>
<tr valign="top" class="odd"><td >Arrow keys</td><td >Changes the current item and selects it.</td></tr>
<tr valign="top" class="even"><td >Ctrl+Arrow keys</td><td >Changes the current item but does not select it.</td></tr>
<tr valign="top" class="odd"><td >Shift+Arrow keys</td><td >Changes the current item and selects it. The previously selected item(s) is not deselected.</td></tr>
<tr valign="top" class="even"><td >Ctr+Space</td><td >Toggles selection of the current item.</td></tr>
<tr valign="top" class="odd"><td >Tab/Backtab</td><td >Changes the current item to the next/previous item.</td></tr>
<tr valign="top" class="even"><td >Home/End</td><td >Selects the first/last item in the model.</td></tr>
<tr valign="top" class="odd"><td >Page up/Page down</td><td >Scrolls the rows shown up/down by the number of visible rows in the view.</td></tr>
<tr valign="top" class="even"><td >Ctrl+A</td><td >Selects all items in the model.</td></tr>
</table></div>
<p>Note that the above table assumes that the <a href="qabstractitemview.html#selectionMode-prop">selection mode</a> allows the operations. For instance, you cannot select items if the selection mode is <a href="qabstractitemview.html#SelectionMode-enum">QAbstractItemView::NoSelection</a>.</p>
<p>The <a href="qabstractitemview.html">QAbstractItemView</a> class is one of the <a href="model-view-programming.html#model-view-classes">Model/View Classes</a> and is part of Qt's <a href="model-view-programming.html">model/view framework</a>.</p>
<p>The view classes that inherit <a href="qabstractitemview.html">QAbstractItemView</a> only need to implement their own view-specific functionality, such as drawing items, returning the geometry of items, finding items, etc.</p>
<p><a href="qabstractitemview.html">QAbstractItemView</a> provides common slots such as <a href="qabstractitemview.html#edit">edit</a>() and <a href="qabstractitemview.html#setCurrentIndex">setCurrentIndex</a>(). Many protected slots are also provided, including <a href="qabstractitemview.html#dataChanged">dataChanged</a>(), <a href="qabstractitemview.html#rowsInserted">rowsInserted</a>(), <a href="qabstractitemview.html#rowsAboutToBeRemoved">rowsAboutToBeRemoved</a>(), <a href="qabstractitemview.html#selectionChanged">selectionChanged</a>(), and <a href="qabstractitemview.html#currentChanged">currentChanged</a>().</p>
<p>The root item is returned by <a href="qabstractitemview.html#rootIndex">rootIndex</a>(), and the current item by <a href="qabstractitemview.html#currentIndex">currentIndex</a>(). To make sure that an item is visible use <a href="qabstractitemview.html#scrollTo">scrollTo</a>().</p>
<p>Some of <a href="qabstractitemview.html">QAbstractItemView</a>'s functions are concerned with scrolling, for example <a href="qabstractitemview.html#horizontalScrollMode-prop">setHorizontalScrollMode</a>() and <a href="qabstractitemview.html#verticalScrollMode-prop">setVerticalScrollMode</a>(). To set the range of the scroll bars, you can, for example, reimplement the view's <a href="qabstractitemview.html#resizeEvent">resizeEvent</a>() function:</p>
<pre class="cpp">
<span class="type">void</span> MyView<span class="operator">::</span>resizeEvent(<span class="type"><a href="../qtgui/qresizeevent.html">QResizeEvent</a></span> <span class="operator">*</span>event) {
horizontalScrollBar()<span class="operator">-</span><span class="operator">></span>setRange(<span class="number">0</span><span class="operator">,</span> realWidth <span class="operator">-</span> width());
<span class="operator">.</span><span class="operator">.</span><span class="operator">.</span>
}
</pre>
<p>Note that the range is not updated until the widget is shown.</p>
<p>Several other functions are concerned with selection control; for example <a href="qabstractitemview.html#selectionMode-prop">setSelectionMode</a>(), and <a href="qabstractitemview.html#selectionBehavior-prop">setSelectionBehavior</a>(). This class provides a default selection model to work with (<a href="qabstractitemview.html#selectionModel">selectionModel</a>()), but this can be replaced by using <a href="qabstractitemview.html#setSelectionModel">setSelectionModel</a>() with an instance of <a href="../qtcore/qitemselectionmodel.html">QItemSelectionModel</a>.</p>
<p>For complete control over the display and editing of items you can specify a delegate with <a href="qabstractitemview.html#setItemDelegate">setItemDelegate</a>().</p>
<p><a href="qabstractitemview.html">QAbstractItemView</a> provides a lot of protected functions. Some are concerned with editing, for example, <a href="qabstractitemview.html#edit">edit</a>(), and <a href="qabstractitemview.html#commitData">commitData</a>(), whilst others are keyboard and mouse event handlers.</p>
<p><b>Note: </b>If you inherit <a href="qabstractitemview.html">QAbstractItemView</a> and intend to update the contents of the viewport, you should use viewport-><a href="qabstractitemview.html#update">update</a>() instead of <a href="qwidget.html#update">update()</a> as all painting operations take place on the viewport.</p></div>
