==Подробное описание==

Класс QItemDelegate обеспечивает вывод и редактирование отдельных элементов модели.

QItemDelegate can be used to provide custom display features and editor widgets for item views based on [[Qt:Документация 4.3.2/qabstractitemview | QAbstractItemView]] subclasses. Using a delegate for this purpose allows the display and editing mechanisms to be customized and developed independently from the model and view.

The QItemDelegate 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]].

When displaying items from a custom model in a standard view, it is often sufficient to simply ensure that the model returns appropriate data for each of the [[Qt:Документация 4.3.2/qt#ItemDataRole-enum | roles]] that determine the appearance of items in views. The default delegate used by Qt's standard views uses this role information to display items in most of the common forms expected by users. However, it is sometimes necessary to have even more control over the appearance of items than the default delegate can provide.

This class provides default implementations of the functions for painting item data in a view and editing data from item models. Default implementations of the [[Qt:Документация 4.3.2/qitemdelegate#paint | paint]]() and [[Qt:Документация 4.3.2/qitemdelegate#sizeHint | sizeHint]]() virtual functions, defined in [[Qt:Документация 4.3.2/qabstractitemdelegate | QAbstractItemDelegate]], are provided to ensure that the delegate implements the correct basic behavior expected by views. You can reimplement these functions in subclasses to customize the appearance of items.

When editing data in an item view, QItemDelegate provides an editor widget, which is a widget that is placed on top of the view while editing takes place. Editors are created with a [[Qt:Документация 4.3.2/qitemeditorfactory | QItemEditorFactory]]; a default static instance provided by [[Qt:Документация 4.3.2/qitemeditorfactory | QItemEditorFactory]] is installed on all item delagates. You can set a custom factory using [[Qt:Документация 4.3.2/qitemdelegate#setItemEditorFactory | setItemEditorFactory]]() or set a new default factory with [[Qt:Документация 4.3.2/qitemeditorfactory#setDefaultFactory | QItemEditorFactory::setDefaultFactory]](). It is the data stored in the item model with the [[Qt:Документация 4.3.2/qt#ItemDataRole-enum | Qt::EditRole]] that is edited.

Only the standard editing functions for widget-based delegates are reimplemented here:

*[[Qt:Документация 4.3.2/qitemdelegate#createEditor | createEditor]]() returns the widget used to change data from the model and can be reimplemented to customize editing behavior.
*[[Qt:Документация 4.3.2/qitemdelegate#setEditorData | setEditorData]]() provides the widget with data to manipulate.
*[[Qt:Документация 4.3.2/qitemdelegate#updateEditorGeometry | updateEditorGeometry]]() ensures that the editor is displayed correctly with respect to the item view.
*[[Qt:Документация 4.3.2/qitemdelegate#setModelData | setModelData]]() returns updated data to the model.

The [[Qt:Документация 4.3.2/qabstractitemdelegate#closeEditor | closeEditor]]() signal indicates that the user has completed editing the data, and that the editor widget can be destroyed.

===Standard Roles and Data Types===

The default delegate used by the standard views supplied with Qt associates each standard role (defined by [[Qt:Документация 4.3.2/qt#ItemDataRole-enum | Qt::ItemDataRole]]) with certain data types. Models that return data in these types can influence the appearance of the delegate as described in the following table.

If the default delegate does not allow the level of customization that you need, either for display purposes or for editing data, it is possible to subclass QItemDelegate to implement the desired behavior.
<div id="subclassing"></div>
===Subclassing===

When subclassing QItemDelegate to create a delegate that displays items using a custom renderer, it is important to ensure that the delegate can render items suitably for all the required states; e.g&#x2e; selected, disabled, checked. The documentation for the [[Qt:Документация 4.3.2/qitemdelegate#paint | paint]]() function contains some hints to show how this can be achieved.

You can provide custom editors by using a [[Qt:Документация 4.3.2/qitemeditorfactory | QItemEditorFactory]]. The [[Qt:Документация 4.3.2/itemviews-coloreditorfactory | Color Editor Factory Example]] shows how a custom editor can be made available to delegates with the default item editor factory. This way, there is no need to subclass QItemDelegate. An alternative is to reimplement [[Qt:Документация 4.3.2/qitemdelegate#createEditor | createEditor]](), [[Qt:Документация 4.3.2/qitemdelegate#setEditorData | setEditorData]](), [[Qt:Документация 4.3.2/qitemdelegate#setModelData | setModelData]](), and [[Qt:Документация 4.3.2/qitemdelegate#updateEditorGeometry | updateEditorGeometry]](). This process is described in the [[Qt:Документация 4.3.2/itemviews-spinboxdelegate | Spin Box Delegate example]].

See also [[Qt:Документация 4.3.2/model-view-delegate | Delegate Classes]], [[Qt:Документация 4.3.2/qabstractitemdelegate | QAbstractItemDelegate]], [[Qt:Документация 4.3.2/itemviews-spinboxdelegate | Spin Box Delegate Example]], [[Qt:Документация 4.3.2/tools-settingseditor | Settings Editor Example]], and [[Qt:Документация 4.3.2/widgets-icons | Icons Example]].

===<div id="eventFilter"></div>bool QItemDelegate::eventFilter ( [[Qt:Документация 4.3.2/qobject | QObject]] * ''editor'', [[Qt:Документация 4.3.2/qevent | QEvent]] * ''event'' )  <tt> [virtual protected]</tt>===

Returns true if the given ''editor'' is a valid [[Qt:Документация 4.3.2/qwidget | QWidget]] and the given ''event'' is handled; otherwise returns false. The following key press events are handled by default:

*'''Tab'''
*'''Backtab'''
*'''Enter'''
*'''Return'''
*'''Esc'''

In the case of '''Tab''', '''Backtab''', '''Enter''' and '''Return''' key press events, the ''editor'''s data is comitted to the model and the editor is closed. If the ''event'' is a '''Tab''' key press the view will open an editor on the next item in the view. Likewise, if the ''event'' is a '''Backtab''' key press the view will open an editor on the ''previous'' item in the view.

If the event is a '''Esc''' key press event, the ''editor'' is closed ''without'' committing its data.

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

See also [[Qt:Документация 4.3.2/qabstractitemdelegate#commitData | commitData]]() and [[Qt:Документация 4.3.2/qabstractitemdelegate#closeEditor | closeEditor]]().

===<div id="itemEditorFactory"></div>[[Qt:Документация 4.3.2/qitemeditorfactory | QItemEditorFactory]] * QItemDelegate::itemEditorFactory () const===

Returns the editor factory used by the item delegate. If no editor factory is set, the function will return null.

See also [[Qt:Документация 4.3.2/qitemdelegate#setItemEditorFactory | setItemEditorFactory]]().

===<div id="paint"></div>void QItemDelegate::paint ( [[Qt:Документация 4.3.2/qpainter | QPainter]] * ''painter'', const [[Qt:Документация 4.3.2/qstyleoptionviewitem | QStyleOptionViewItem]] &amp; ''option'', const [[Qt:Документация 4.3.2/qmodelindex | QModelIndex]] &amp; ''index'' ) const  <tt> [virtual]</tt>===

Renders the delegate using the given ''painter'' and style ''option'' for the item specified by ''index''.

When reimplementing this function in a subclass, you should update the area held by the option's [[Qt:Документация 4.3.2/qstyleoption#rect-var | rect]] variable, using the option's [[Qt:Документация 4.3.2/qstyleoption#state-var | state]] variable to determine the state of the item to be displayed, and adjust the way it is painted accordingly.

For example, a selected item may need to be displayed differently to unselected items, as shown in the following code:
<source lang="cpp-qt">     if (option.state &amp; QStyle::State_Selected)
         painter->fillRect(option.rect, option.palette.highlight());

     int size = qMin(option.rect.width(), option.rect.height());
     int brightness = index.model()->data(index, Qt::DisplayRole).toInt();
     double radius = (size/2.0) - (brightness/255.0 * size/2.0);
     if (radius == 0.0)
         return;

     painter->save();
     painter->setRenderHint(QPainter::Antialiasing, true);
     painter->setPen(Qt::NoPen);
     if (option.state &amp; QStyle::State_Selected)
         painter->setBrush(option.palette.highlightedText());
     else
     ...</source> 
After painting, you should ensure that the painter is returned to its the state it was supplied in when this function was called. For example, it may be useful to call [[Qt:Документация 4.3.2/qpainter#save | QPainter::save]]() before painting and [[Qt:Документация 4.3.2/qpainter#restore | QPainter::restore]]() afterwards.

Reimplemented from [[Qt:Документация 4.3.2/qabstractitemdelegate#paint | QAbstractItemDelegate]].

See also [[Qt:Документация 4.3.2/qstyle#StateFlag-enum | QStyle::State]].

===<div id="setEditorData"></div>void QItemDelegate::setEditorData ( [[Qt:Документация 4.3.2/qwidget | QWidget]] * ''editor'', const [[Qt:Документация 4.3.2/qmodelindex | QModelIndex]] &amp; ''index'' ) const  <tt> [virtual]</tt>===

Sets the data to be displayed and edited by the ''editor'' for the item specified by ''index''.

The default implementation uses the editor's user property to set values.

Reimplemented from [[Qt:Документация 4.3.2/qabstractitemdelegate#setEditorData | QAbstractItemDelegate]].

See also [[Qt:Документация 4.3.2/qmetaproperty#isUser | QMetaProperty::isUser]]().

===<div id="setItemEditorFactory"></div>void QItemDelegate::setItemEditorFactory ( [[Qt:Документация 4.3.2/qitemeditorfactory | QItemEditorFactory]] * ''factory'' )===

Sets the editor factory to be used by the item delegate to be the ''factory'' specified. If no editor factory is set, the item delegate will use the default editor factory.

See also [[Qt:Документация 4.3.2/qitemdelegate#itemEditorFactory | itemEditorFactory]]().

===<div id="setModelData"></div>void QItemDelegate::setModelData ( [[Qt:Документация 4.3.2/qwidget | QWidget]] * ''editor'', [[Qt:Документация 4.3.2/qabstractitemmodel | QAbstractItemModel]] * ''model'', const [[Qt:Документация 4.3.2/qmodelindex | QModelIndex]] &amp; ''index'' ) const  <tt> [virtual]</tt>===

Sets the data for the specified ''model'' and item ''index'' from that supplied by the ''editor''.

The default implementation uses the editor's user property to get values.

Reimplemented from [[Qt:Документация 4.3.2/qabstractitemdelegate#setModelData | QAbstractItemDelegate]].

See also [[Qt:Документация 4.3.2/qmetaproperty#isUser | QMetaProperty::isUser]]().

===<div id="sizeHint"></div>[[Qt:Документация 4.3.2/qsize | QSize]] QItemDelegate::sizeHint ( const [[Qt:Документация 4.3.2/qstyleoptionviewitem | QStyleOptionViewItem]] &amp; ''option'', const [[Qt:Документация 4.3.2/qmodelindex | QModelIndex]] &amp; ''index'' ) const  <tt> [virtual]</tt>===

Returns the size needed by the delegate to display the item specified by ''index'', taking into account the style information provided by ''option''.

When reimplementing this function, note that in case of text items, [[Qt:Документация 4.3.2/qitemdelegate | QItemDelegate]] adds a margin (i.e&#x2e; 2 * [[Qt:Документация 4.3.2/qstyle#PixelMetric-enum | QStyle::PM_FocusFrameHMargin]]) to the length of the text.

Reimplemented from [[Qt:Документация 4.3.2/qabstractitemdelegate#sizeHint | QAbstractItemDelegate]].

===<div id="updateEditorGeometry"></div>void QItemDelegate::updateEditorGeometry ( [[Qt:Документация 4.3.2/qwidget | QWidget]] * ''editor'', const [[Qt:Документация 4.3.2/qstyleoptionviewitem | QStyleOptionViewItem]] &amp; ''option'', const [[Qt:Документация 4.3.2/qmodelindex | QModelIndex]] &amp; ''index'' ) const  <tt> [virtual]</tt>===

Updates the ''editor'' for the item specified by ''index'' according to the style ''option'' given.

Reimplemented from [[Qt:Документация 4.3.2/qabstractitemdelegate#updateEditorGeometry | QAbstractItemDelegate]].
