==Подробное описание==

The QAbstractItemView class provides the basic functionality for item view classes.

QAbstractItemView class is the base class for every standard view that uses a [[Qt:Документация 4.3.2/qabstractitemmodel | QAbstractItemModel]]. 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 QAbstractItemView class is one of the [[Qt:Документация 4.3.2/model-view | Model/View Classes]] and is part of Qt's [[Qt:Документация 4.3.2/model-view-programming | model/view framework]].

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.

QAbstractItemView provides common slots such as [[Qt:Документация 4.3.2/qabstractitemview#edit | edit]]() and [[Qt:Документация 4.3.2/qabstractitemview#setCurrentIndex | setCurrentIndex]](). Many protected slots are also provided, including [[Qt:Документация 4.3.2/qabstractitemview#dataChanged | dataChanged]](), [[Qt:Документация 4.3.2/qabstractitemview#rowsInserted | rowsInserted]](), [[Qt:Документация 4.3.2/qabstractitemview#rowsAboutToBeRemoved | rowsAboutToBeRemoved]](), [[Qt:Документация 4.3.2/qabstractitemview#selectionChanged | selectionChanged]](), and [[Qt:Документация 4.3.2/qabstractitemview#currentChanged | currentChanged]]().

The root item is returned by [[Qt:Документация 4.3.2/qabstractitemview#rootIndex | rootIndex]](), and the current item by [[Qt:Документация 4.3.2/qabstractitemview#currentIndex | currentIndex]](). To make sure that an item is visible use [[Qt:Документация 4.3.2/qabstractitemview#scrollTo | scrollTo]]().

Some of QAbstractItemView's functions are concerned with scrolling, for example [[Qt:Документация 4.3.2/qabstractitemview#horizontalScrollMode-prop | setHorizontalScrollMode]]() and [[Qt:Документация 4.3.2/qabstractitemview#verticalScrollMode-prop | setVerticalScrollMode]](). To set the range of the scroll bars, you can, for example, reimplement the view's [[Qt:Документация 4.3.2/qabstractitemview#resizeEvent | resizeEvent]]() function:
<source lang="cpp-qt"> void MyView::resizeEvent(QResizeEvent *event) {
     horizontalScrollBar()->setRange(0, realWidth - width());
     ...
 }</source> 
Note that the range is not updated until the widget is shown.

Several other functions are concerned with selection control; for example [[Qt:Документация 4.3.2/qabstractitemview#selectionMode-prop | setSelectionMode]](), and [[Qt:Документация 4.3.2/qabstractitemview#selectionBehavior-prop | setSelectionBehavior]](). This class provides a default selection model to work with ([[Qt:Документация 4.3.2/qabstractitemview#selectionModel | selectionModel]]()), but this can be replaced by using [[Qt:Документация 4.3.2/qabstractitemview#setSelectionModel | setSelectionModel]]() with an instance of [[Qt:Документация 4.3.2/qitemselectionmodel | QItemSelectionModel]].

For complete control over the display and editing of items you can specify a delegate with [[Qt:Документация 4.3.2/qabstractitemview#setItemDelegate | setItemDelegate]]().

QAbstractItemView provides a lot of protected functions. Some are concerned with editing, for example, [[Qt:Документация 4.3.2/qabstractitemview#edit | edit]](), and [[Qt:Документация 4.3.2/qabstractitemview#commitData | commitData]](), whilst others are keyboard and mouse event handlers.

Sets the given ''widget'' on the item at the given ''index'', passing the ownership of the widget to the viewport.

If ''index'' is invalid (e.g&#x2e;, if you pass the root index), this function will do nothing.

Note that the given ''widget'''s [[Qt:Документация 4.3.2/qwidget | autoFillBackground]] property must be set to true, otherwise the widget's background will be transparent, showing both the model data and the item at the given ''index''.

This function should only be used to display static content within the visible area corresponding to an item of data. If you want to display custom dynamic content or implement a custom editor widget, subclass [[Qt:Документация 4.3.2/qitemdelegate | QItemDelegate]] instead.

This function was introduced in Qt 4.1.

See also [[Qt:Документация 4.3.2/qabstractitemview#indexWidget | indexWidget]]() and [[Qt:Документация 4.3.2/model-view-delegate | Delegate Classes]].

===<div id="setItemDelegate"></div>void QAbstractItemView::setItemDelegate ( [[Qt:Документация 4.3.2/qabstractitemdelegate | QAbstractItemDelegate]] * ''delegate'' )===

Sets the item delegate for this view and its model to ''delegate''. This is useful if you want complete control over the editing and display of items.

Any existing delegate will be removed, but not deleted. [[Qt:Документация 4.3.2/qabstractitemview | QAbstractItemView]] does not take ownership of ''delegate''.

'''Warning:''' You should not share the same instance of a delegate between views. Doing so can cause incorrect or unintuitive editing behavior since each view connected to a given delegate may receive the [[Qt:Документация 4.3.2/qabstractitemdelegate#closeEditor | closeEditor()]] signal, and attempt to access, modify or close an editor that has already been closed.

See also [[Qt:Документация 4.3.2/qabstractitemview#itemDelegate | itemDelegate]]().

===<div id="setItemDelegateForColumn"></div>void QAbstractItemView::setItemDelegateForColumn ( int ''column'', [[Qt:Документация 4.3.2/qabstractitemdelegate | QAbstractItemDelegate]] * ''delegate'' )===

Sets the given item ''delegate'' used by this view and model for the given ''column''. All items on ''column'' will be drawn and managed by ''delegate'' instead of using the default delegate (i.e&#x2e;, [[Qt:Документация 4.3.2/qabstractitemview#itemDelegate | itemDelegate]]()).

Any existing column delegate for ''column'' will be removed, but not deleted. [[Qt:Документация 4.3.2/qabstractitemview | QAbstractItemView]] does not take ownership of ''delegate''.

'''Note:''' If a delegate has been assigned to both a row and a column, the row delegate will take presedence and manage the intersecting cell index.

'''Warning:''' You should not share the same instance of a delegate between views. Doing so can cause incorrect or unintuitive editing behavior since each view connected to a given delegate may receive the [[Qt:Документация 4.3.2/qabstractitemdelegate#closeEditor | closeEditor()]] signal, and attempt to access, modify or close an editor that has already been closed.

This function was introduced in Qt 4.2.

See also [[Qt:Документация 4.3.2/qabstractitemview#itemDelegateForColumn | itemDelegateForColumn]](), [[Qt:Документация 4.3.2/qabstractitemview#setItemDelegateForRow | setItemDelegateForRow]](), and [[Qt:Документация 4.3.2/qabstractitemview#itemDelegate | itemDelegate]]().

===<div id="setItemDelegateForRow"></div>void QAbstractItemView::setItemDelegateForRow ( int ''row'', [[Qt:Документация 4.3.2/qabstractitemdelegate | QAbstractItemDelegate]] * ''delegate'' )===

Sets the given item ''delegate'' used by this view and model for the given ''row''. All items on ''row'' will be drawn and managed by ''delegate'' instead of using the default delegate (i.e&#x2e;, [[Qt:Документация 4.3.2/qabstractitemview#itemDelegate | itemDelegate]]()).

Any existing row delegate for ''row'' will be removed, but not deleted. [[Qt:Документация 4.3.2/qabstractitemview | QAbstractItemView]] does not take ownership of ''delegate''.

'''Note:''' If a delegate has been assigned to both a row and a column, the row delegate (i.e&#x2e;, this delegate) will take presedence and manage the intersecting cell index.

'''Warning:''' You should not share the same instance of a delegate between views. Doing so can cause incorrect or unintuitive editing behavior since each view connected to a given delegate may receive the [[Qt:Документация 4.3.2/qabstractitemdelegate#closeEditor | closeEditor()]] signal, and attempt to access, modify or close an editor that has already been closed.

This function was introduced in Qt 4.2.

===<div id="setModel"></div>void QAbstractItemView::setModel ( [[Qt:Документация 4.3.2/qabstractitemmodel | QAbstractItemModel]] * ''model'' )  <tt> [virtual]</tt>===

Sets the ''model'' for the view to present.

'''Note:''' This function will also create and set a new selection model, replacing any previously set with [[Qt:Документация 4.3.2/qabstractitemview#setSelectionModel | setSelectionModel]](), but the old selection model will not be deleted.

See also [[Qt:Документация 4.3.2/qabstractitemview#model | model]](), [[Qt:Документация 4.3.2/qabstractitemview#selectionModel | selectionModel]](), and [[Qt:Документация 4.3.2/qabstractitemview#setSelectionModel | setSelectionModel]]().

===<div id="setRootIndex"></div>void QAbstractItemView::setRootIndex ( const [[Qt:Документация 4.3.2/qmodelindex | QModelIndex]] &amp; ''index'' )  <tt> [virtual slot]</tt>===

Sets the root item to the item at the given ''index''.

See also [[Qt:Документация 4.3.2/qabstractitemview#rootIndex | rootIndex]]().

===<div id="setSelection"></div>void QAbstractItemView::setSelection ( const [[Qt:Документация 4.3.2/qrect | QRect]] &amp; ''rect'', [[Qt:Документация 4.3.2/qitemselectionmodel#SelectionFlag-enum | QItemSelectionModel::SelectionFlags]] ''flags'' )  <tt> [pure virtual protected]</tt>===

Applies the selection ''flags'' to the items in or touched by the rectangle, ''rect''.

When implementing your own itemview setSelection should call [[Qt:Документация 4.3.2/qabstractitemview#selectionModel | selectionModel]]()->select(selection, flags) where selection is either an empty [[Qt:Документация 4.3.2/qmodelindex | QModelIndex]] or a [[Qt:Документация 4.3.2/qitemselection | QItemSelection]] that contains all items that are contained in ''rect''.

See also [[Qt:Документация 4.3.2/qabstractitemview#selectionCommand | selectionCommand]]() and [[Qt:Документация 4.3.2/qabstractitemview#selectedIndexes | selectedIndexes]]().

===<div id="setSelectionModel"></div>void QAbstractItemView::setSelectionModel ( [[Qt:Документация 4.3.2/qitemselectionmodel | QItemSelectionModel]] * ''selectionModel'' )  <tt> [virtual]</tt>===

Sets the current selection model to the given ''selectionModel''.

Note that, if you call [[Qt:Документация 4.3.2/qabstractitemview#setModel | setModel]]() after this function, the given ''selectionModel'' will be replaced by a one created by the view.

See also [[Qt:Документация 4.3.2/qabstractitemview#selectionModel | selectionModel]](), [[Qt:Документация 4.3.2/qabstractitemview#setModel | setModel]](), and [[Qt:Документация 4.3.2/qabstractitemview#clearSelection | clearSelection]]().

===<div id="setState"></div>void QAbstractItemView::setState ( [[Qt:Документация 4.3.2/qabstractitemview#State-enum | State]] ''state'' )  <tt> [protected]</tt>===

Sets the item view's state to the given ''state''.

See also [[Qt:Документация 4.3.2/qabstractitemview#state | state]]().

===<div id="sizeHintForColumn"></div>int QAbstractItemView::sizeHintForColumn ( int ''column'' ) const  <tt> [virtual]</tt>===

Returns the width size hint for the specified ''column'' or -1 if there is no model.

This function is used in views with a horizontal header to find the size hint for a header section based on the contents of the given ''column''.

See also [[Qt:Документация 4.3.2/qabstractitemview#sizeHintForRow | sizeHintForRow]]().

===<div id="sizeHintForIndex"></div>[[Qt:Документация 4.3.2/qsize | QSize]] QAbstractItemView::sizeHintForIndex ( const [[Qt:Документация 4.3.2/qmodelindex | QModelIndex]] &amp; ''index'' ) const===

Returns the size hint for the item with the specified ''index'' or an invalid size for invalid indexes.

See also [[Qt:Документация 4.3.2/qabstractitemview#sizeHintForRow | sizeHintForRow]]() and [[Qt:Документация 4.3.2/qabstractitemview#sizeHintForColumn | sizeHintForColumn]]().

===<div id="sizeHintForRow"></div>int QAbstractItemView::sizeHintForRow ( int ''row'' ) const  <tt> [virtual]</tt>===

Returns the height size hint for the specified ''row'' or -1 if there is no model.

The returned height is calculated using the size hints of the given ''row'''s items, i.e&#x2e; the returned value is the maximum height among the items. Note that to control the height of a row, you must reimplement the [[Qt:Документация 4.3.2/qabstractitemdelegate#sizeHint | QAbstractItemDelegate::sizeHint]]() function.

This function is used in views with a vertical header to find the size hint for a header section based on the contents of the given ''row''.

See also [[Qt:Документация 4.3.2/qabstractitemview#sizeHintForColumn | sizeHintForColumn]]().

===<div id="startDrag"></div>void QAbstractItemView::startDrag ( [[Qt:Документация 4.3.2/qt#DropAction-enum | Qt::DropActions]] ''supportedActions'' )  <tt> [virtual protected]</tt>===

Starts a drag by calling drag->start() using the given ''supportedActions''.

Reimplemented from [[Qt:Документация 4.3.2/qobject#timerEvent | QObject]].

See also [[Qt:Документация 4.3.2/qobject#timerEvent | QObject::timerEvent]]().

===<div id="update"></div>void QAbstractItemView::update ( const [[Qt:Документация 4.3.2/qmodelindex | QModelIndex]] &amp; ''index'' )  <tt> [slot]</tt>===

Updates the area occupied by the given ''index''.

This function was introduced in Qt 4.3.

===<div id="verticalOffset"></div>int QAbstractItemView::verticalOffset () const  <tt> [pure virtual protected]</tt>===

Returns the vertical offset of the view.

In the base class this is a pure virtual function.

See also [[Qt:Документация 4.3.2/qabstractitemview#horizontalOffset | horizontalOffset]]().

===<div id="viewOptions"></div>[[Qt:Документация 4.3.2/qstyleoptionviewitem | QStyleOptionViewItem]] QAbstractItemView::viewOptions () const  <tt> [virtual protected]</tt>===

This function is used to handle tool tips, and What's This? mode, if the given ''event'' is a [[Qt:Документация 4.3.2/qevent#Type-enum | QEvent::ToolTip]],or a [[Qt:Документация 4.3.2/qevent#Type-enum | QEvent::WhatsThis]]. It passes all other events on to its base class viewportEvent() handler.

Reimplemented from [[Qt:Документация 4.3.2/qabstractscrollarea#viewportEvent | QAbstractScrollArea]].

===<div id="visualRect"></div>[[Qt:Документация 4.3.2/qrect | QRect]] QAbstractItemView::visualRect ( const [[Qt:Документация 4.3.2/qmodelindex | QModelIndex]] &amp; ''index'' ) const  <tt> [pure virtual]</tt>===

Returns the rectangle on the viewport occupied by the item at ''index''.

If your item is displayed in several areas then visualRect should return the primary area that contains index and not the complete area that index might encompasses, touch or cause drawing.

In the base class this is a pure virtual function.

See also [[Qt:Документация 4.3.2/qabstractitemview#indexAt | indexAt]]() and [[Qt:Документация 4.3.2/qabstractitemview#visualRegionForSelection | visualRegionForSelection]]().
