The QAbstractItemView class provides the basic functionality for item view classes.
QAbstractItemView class is the base class for every standard view that uses a 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 keyboard navigation implements this functionality:
| Keys | Functionality |
| Arrow keys | Changes the current item and selects it. |
| Ctrl+Arrow keys | Changes the current item but does not select it. |
| Shift+Arrow keys | Changes the current item and selects it. The previously selected item(s) is not deselected. |
| Ctr+Space | Toggles selection of the current item. |
| Tab/Backtab | Changes the current item to the next/previous item. |
| Home/End | Selects the first/last item in the model. |
| Page up/Page down | Scrolls the rows shown up/down by the number of visible rows in the view. |
| Ctrl+A | Selects all items in the model. |
Note that the above table assumes that the selection mode allows the operations. For instance, you cannot select items if the selection mode is QAbstractItemView::NoSelection.
The QAbstractItemView class is one of the Model/View Classes and is part of Qt's 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 edit() and setCurrentIndex(). Many protected slots are also provided, including dataChanged(), rowsInserted(), rowsAboutToBeRemoved(), selectionChanged(), and currentChanged().
The root item is returned by rootIndex(), and the current item by currentIndex(). To make sure that an item is visible use scrollTo().
Some of QAbstractItemView's functions are concerned with scrolling, for example setHorizontalScrollMode() and setVerticalScrollMode(). To set the range of the scroll bars, you can, for example, reimplement the view's resizeEvent() function:
Note that the range is not updated until the widget is shown.
Several other functions are concerned with selection control; for example setSelectionMode(), and setSelectionBehavior(). This class provides a default selection model to work with (selectionModel()), but this can be replaced by using setSelectionModel() with an instance of QItemSelectionModel.
For complete control over the display and editing of items you can specify a delegate with setItemDelegate().
QAbstractItemView provides a lot of protected functions. Some are concerned with editing, for example, edit(), and commitData(), whilst others are keyboard and mouse event handlers.

Sets the model for the view to present.
This function will create and set a new selection model, replacing any model that was previously set with setSelectionModel(). 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:
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 deleteLater() functions to explicitly delete them.
The view does not take ownership of the model unless it is the model's parent object because the model may be shared between many different views.

If its value is true, the selected data will overwrite the existing item data when dropped, while moving the data will clear the item. If its value is false, the selected data will be inserted as a new item when the data is dropped. When the data is moved, the item is removed as well.
The default value is false, as in the QListView and QTreeView subclasses. In the QTableView subclass, on the other hand, the property has been set to true.
