<h2>Detailed Description</h2>
210
<p>The QAbstractItemView class provides the basic functionality for item view classes.</p>
211
<p>QAbstractItemView class is the base class for every standard view that uses a <a href="qabstractitemmodel.html">QAbstractItemModel</a>. QAbstractItemView 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.</p>
212
<p>The QAbstractItemView class is one of the <a href="model-view.html">Model/View Classes</a> and is part of Qt's <a href="model-view-programming.html">model/view framework</a>.</p>
213
<p>The view classes that inherit QAbstractItemView only need to implement their own view-specific functionality, such as drawing items, returning the geometry of items, finding items, etc.</p>
214
<p>QAbstractItemView 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>(), columnsInserted(), columnsRemoved(), <a href="qabstractitemview.html#selectionChanged">selectionChanged</a>(), and <a href="qabstractitemview.html#currentChanged">currentChanged</a>().</p>
215
<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>
216
<p>Some of QAbstractItemView's functions are concerned with scrolling, for example setHorizontalFactor() and setVerticalFactor(). 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="qitemselectionmodel.html">QItemSelectionModel</a>.</p>
217
<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>
218
<p>QAbstractItemView 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>
