the basic functionality for
item view classes.</p>
<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. The keyboard navigation
implements this functionality:</p>
<table class="generic">
<thead>
<tr class="qt-style">
<th>Keys</th>
<th>Functionality</th>
</tr>
</thead>
<tr class="odd" valign="top">
<td>Arrow keys</td>
<td>Changes the current item and selects it.</td>
</tr>
<tr class="even" valign="top">
<td>Ctrl+Arrow keys</td>
<td>Changes the current item but does not select it.</td>
</tr>
<tr class="odd" valign="top">
<td>Shift+Arrow keys</td>
<td>Changes the current item and selects it. The previously
selected item(s) is not deselected.</td>
</tr>
<tr class="even" valign="top">

<td>Toggles selection of the current item.</td>

<tr class="odd" valign="top">

</tr>
<tr class="even" valign="top">
<td>Home/End</td>
<td>Selects the first/last item in the model.</td>

<tr class="odd" valign="top">
<td>Page up/Page down</td>
<td>Scrolls the rows shown up/down by the number of visible rows in
the view.</td>

<tr class="even" valign="top">

</tr>
</table>
<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 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>
<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>
<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>(),
<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 QAbstractItemView'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><a href="qabstractitemview.html#resizeEvent">resizeEvent</a>(<span class="type"><a href="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="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>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>
<p><b>Note:</b> If you inherit QAbstractItemView 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>

<p>This function will create and set a new selection model,
replacing any model that was previously set with <a href="qabstractitemview.html#setSelectionModel">setSelectionModel</a>().
However, the old selection model will not be deleted as it may be
shared between several views. We recommend that you delete the old
selection model if it is no longer required. This is done with the
following code:</p>
<pre class="cpp">
<span class="type"><a href="qitemselectionmodel.html">QItemSelectionModel</a></span> <span class="operator">*</span>m <span class="operator">=</span> view<span class="operator">-</span><span class="operator">></span><a href="qabstractitemview.html#selectionModel">selectionModel</a>();
view<span class="operator">-</span><span class="operator">></span>setModel(<span class="keyword">new</span> model);
<span class="keyword">delete</span> m;
</pre>
<p>If both the old model and the old selection model do not have
parents, or if their parents are long-lived objects, it may be
preferable to call their <a href="qobject.html#deleteLater">deleteLater</a>() functions to
explicitly delete them.</p>
<p>The view <i>does not</i> take ownership of the model unless it
is the model's parent object because the model may be shared
between many different views.</p>

the rectangle, <i>rect</i>.</p>
<p>When implementing your own itemview setSelection should call
<a href="qabstractitemview.html#selectionModel">selectionModel</a>()->select(selection,
flags) where selection is either an empty <a href="qmodelindex.html">QModelIndex</a> or a <a href="qitemselection.html">QItemSelection</a> that contains all items
that are contained in <i>rect</i>.</p>

<p>Note that, if you call <a href="qabstractitemview.html#setModel">setModel</a>() after this
function, the given <i>selectionModel</i> will be replaced by one
created by the view.</p>
<p><b>Note:</b> It is up to the application to delete the old
selection model if it is no longer needed; i.e., if it is not being
used by other views. This will happen automatically when its parent
object is deleted. However, if it does not have a parent, or if the
parent is a long-lived object, it may be preferable to call its
<a href="qobject.html#deleteLater">deleteLater</a>() function to
explicitly delete it.</p>
