Detailed Description

The QItemDelegate class provides display and editing facilities for data items from a model.

\inmodule QtWidgets

QItemDelegate can be used to provide custom display features and editor widgets for item views based on 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 \l{Model/View Classes} and is part of Qt's \l{Model/View Programming}{model/view framework}. Note that QStyledItemDelegate has taken over the job of drawing Qt's item views. We recommend the use of QStyledItemDelegate when creating new delegates.

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 \l{Qt::ItemDataRole}{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 paint() and sizeHint() virtual functions, defined in 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 QItemEditorFactory; a default static instance provided by QItemEditorFactory is installed on all item delegates. You can set a custom factory using setItemEditorFactory() or set a new default factory with QItemEditorFactory::setDefaultFactory(). It is the data stored in the item model with the Qt::EditRole that is edited.

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

\list

createEditor() returns the widget used to change data from the model and can be reimplemented to customize editing behavior.
setEditorData() provides the widget with data to manipulate.
updateEditorGeometry() ensures that the editor is displayed correctly with respect to the item view.
setModelData() returns updated data to the model. \endlist

The closeEditor() signal indicates that the user has completed editing the data, and that the editor widget can be destroyed.

overridevirtual

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 \l{QStyleOption::rect}{rect} variable, using the option's \l{QStyleOption::state}{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:

if (option.state & QStyle::State_Selected)

painter->fillRect(option.rect, option.palette.highlight());

QStyle::State_Selected

@ State_Selected

Definition qstyle.h:83

option

GLuint GLenum option

Definition qopenglext.h:5929

painter

QPainter painter(this)

[7]

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 QPainter::save() before painting and QPainter::restore() afterwards.
