QAbstractItemView::QAbstractItemView(QWidget *parent = nullptr)

Constructs an abstract item view with the given parent.

[signal] void QAbstractItemView::activated(const QModelIndex &index)

This signal is emitted when the item specified by index is activated by the user. How to activate items depends on the platform; e.g., by single- or double-clicking the item, or by pressing the Return or Enter key when the item is current.

See also clicked(), doubleClicked(), entered(), and pressed().

[slot] void QAbstractItemView::clearSelection()

Deselects all selected items. The current index will not be changed.

See also setSelection() and selectAll().

[signal] void QAbstractItemView::clicked(const QModelIndex &index)

This signal is emitted when a mouse button is left-clicked. The item the mouse was clicked on is specified by index. The signal is only emitted when the index is valid.

See also activated(), doubleClicked(), entered(), and pressed().

[virtual protected slot] void QAbstractItemView::closeEditor(QWidget *editor, QAbstractItemDelegate::EndEditHint hint)

Closes the given editor, and releases it. The hint is used to specify how the view should respond to the end of the editing operation. For example, the hint may indicate that the next item in the view should be opened for editing.

See also edit() and commitData().

[virtual protected slot] void QAbstractItemView::commitData(QWidget *editor)

Commit the data in the editor to the model.

See also closeEditor().

[virtual protected slot] void QAbstractItemView::currentChanged(const QModelIndex &current, const QModelIndex &previous)

This slot is called when a new item becomes the current item. The previous current item is specified by the previous index, and the new item by the current index.

If you want to know about changes to items see the dataChanged() signal.

[virtual protected slot] void QAbstractItemView::dataChanged(const QModelIndex &topLeft, const QModelIndex &bottomRight, const QVector<int> &roles = QVector<int>())

This slot is called when items with the given roles are changed in the model. The changed items are those from topLeft to bottomRight inclusive. If just one item is changed topLeft == bottomRight.

The roles which have been changed can either be an empty container (meaning everything has changed), or a non-empty container with the subset of roles which have changed.

Note: : Qt::ToolTipRole is not honored by dataChanged() in the views provided by Qt.

[signal] void QAbstractItemView::doubleClicked(const QModelIndex &index)

This signal is emitted when a mouse button is double-clicked. The item the mouse was double-clicked on is specified by index. The signal is only emitted when the index is valid.

See also clicked() and activated().

[slot] void QAbstractItemView::edit(const QModelIndex &index)

Starts editing the item corresponding to the given index if it is editable.

Note that this function does not change the current index. Since the current index defines the next and previous items to edit, users may find that keyboard navigation does not work as expected. To provide consistent navigation behavior, call setCurrentIndex() before this function with the same model index.

See also QModelIndex::flags().

[virtual protected slot] void QAbstractItemView::editorDestroyed(QObject *editor)

This function is called when the given editor has been destroyed.

See also closeEditor().

[signal] void QAbstractItemView::entered(const QModelIndex &index)

This signal is emitted when the mouse cursor enters the item specified by index. Mouse tracking needs to be enabled for this feature to work.

See also viewportEntered(), activated(), clicked(), doubleClicked(), and pressed().

[signal] void QAbstractItemView::pressed(const QModelIndex &index)

This signal is emitted when a mouse button is pressed. The item the mouse was pressed on is specified by index. The signal is only emitted when the index is valid.

Use the QGuiApplication::mouseButtons() function to get the state of the mouse buttons.

See also activated(), clicked(), doubleClicked(), and entered().

[virtual slot] void QAbstractItemView::reset()

Reset the internal state of the view.

Warning: This function will reset open editors, scroll bar positions, selections, etc. Existing changes will not be committed. If you would like to save your changes when resetting the view, you can reimplement this function, commit your changes, and then call the superclass' implementation.

[virtual protected slot] void QAbstractItemView::rowsAboutToBeRemoved(const QModelIndex &parent, int start, int end)

This slot is called when rows are about to be removed. The deleted rows are those under the given parent from start to end inclusive.

See also rowsInserted().

[virtual protected slot] void QAbstractItemView::rowsInserted(const QModelIndex &parent, int start, int end)

This slot is called when rows are inserted. The new rows are those under the given parent from start to end inclusive. The base class implementation calls fetchMore() on the model to check for more data.

See also rowsAboutToBeRemoved().

[slot] void QAbstractItemView::scrollToBottom()

Scrolls the view to the bottom.

This function was introduced in Qt 4.1.

See also scrollTo() and scrollToTop().

[slot] void QAbstractItemView::scrollToTop()

Scrolls the view to the top.

This function was introduced in Qt 4.1.

See also scrollTo() and scrollToBottom().

[virtual slot] void QAbstractItemView::selectAll()

Selects all items in the view. This function will use the selection behavior set on the view when selecting.

See also setSelection(), selectedIndexes(), and clearSelection().

[virtual protected slot] void QAbstractItemView::selectionChanged(const QItemSelection &selected, const QItemSelection &deselected)

This slot is called when the selection is changed. The previous selection (which may be empty), is specified by deselected, and the new selection by selected.

See also setSelection().

[slot] void QAbstractItemView::setCurrentIndex(const QModelIndex &index)

Sets the current item to be the item at index.

Unless the current selection mode is NoSelection, the item is also selected. Note that this function also updates the starting position for any new selections the user performs.

To set an item as the current item without selecting it, call

selectionModel()->setCurrentIndex(index, QItemSelectionModel::NoUpdate);

See also currentIndex(), currentChanged(), and selectionMode.

[virtual slot] void QAbstractItemView::setRootIndex(const QModelIndex &index)

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

This function is called with the given event when a key event is sent to the widget. The default implementation handles basic cursor movement, e.g. Up, Down, Left, Right, Home, PageUp, and PageDown; the activated() signal is emitted if the current index is valid and the activation key is pressed (e.g. Enter or Return, depending on the platform). This function is where editing is initiated by key press, e.g. if F2 is pressed.

See also edit(), moveCursor(), keyboardSearch(), and tabKeyNavigation.

[virtual] void QAbstractItemView::keyboardSearch(const QString &search)

Moves to and selects the item best matching the string search. If no item is found nothing happens.

In the default implementation, the search is reset if search is empty, or the time interval since the last search has exceeded QApplication::keyboardInputInterval().

Reimplements: QAbstractScrollArea::mousePressEvent(QMouseEvent *e).

This function is called with the given event when a mouse button is pressed while the cursor is inside the widget. If a valid item is pressed on it is made into the current item. This function emits the pressed() signal.

[override virtual protected] void QAbstractItemView::mouseReleaseEvent(QMouseEvent *event)

Reimplements: QAbstractScrollArea::mouseReleaseEvent(QMouseEvent *e).

This function is called with the given event when a mouse button is released, after a mouse press event on the widget. If a user presses the mouse inside your widget and then drags the mouse to another location before releasing the mouse button, your widget receives the release event. The function will emit the clicked() signal if an item was being pressed.

[pure virtual protected] QModelIndex QAbstractItemView::moveCursor(QAbstractItemView::CursorAction cursorAction, Qt::KeyboardModifiers modifiers)

Returns a QModelIndex object pointing to the next object in the view, based on the given cursorAction and keyboard modifiers specified by modifiers.

In the base class this is a pure virtual function.

See also setRootIndex().

[protected] void QAbstractItemView::scheduleDelayedItemsLayout()

Schedules a layout of the items in the view to be executed when the event processing starts.

Even if scheduleDelayedItemsLayout() is called multiple times before events are processed, the view will only do the layout once.

See also executeDelayedItemsLayout().

[protected] void QAbstractItemView::scrollDirtyRegion(int dx, int dy)

Prepares the view for scrolling by (dx,dy) pixels by moving the dirty regions in the opposite direction. You only need to call this function if you are implementing a scrolling viewport in your view subclass.

If you implement scrollContentsBy() in a subclass of QAbstractItemView, call this function before you call QWidget::scroll() on the viewport. Alternatively, just call update().

See also scrollContentsBy(), dirtyRegionOffset(), and setDirtyRegion().

[pure virtual] void QAbstractItemView::scrollTo(const QModelIndex &index, QAbstractItemView::ScrollHint hint = EnsureVisible)

Scrolls the view if necessary to ensure that the item at index is visible. The view will try to position the item according to the given hint.

In the base class this is a pure virtual function.

[virtual protected] QModelIndexList QAbstractItemView::selectedIndexes() const

This convenience function returns a list of all selected and non-hidden item indexes in the view. The list contains no duplicates, and is not sorted.

See also QItemSelectionModel::selectedIndexes().

[virtual protected] QItemSelectionModel::SelectionFlags QAbstractItemView::selectionCommand(const QModelIndex &index, const QEvent *event = nullptr) const

Returns the SelectionFlags to be used when updating a selection with to include the index specified. The event is a user input event, such as a mouse or keyboard event.

Reimplement this function to define your own selection behavior.

Returns the current selection model.

See also setSelectionModel() and selectedIndexes().

[protected] void QAbstractItemView::setDirtyRegion(const QRegion &region)

Marks the given region as dirty and schedules it to be updated. You only need to call this function if you are implementing your own view subclass.

This function was introduced in Qt 4.1.

See also scrollDirtyRegion() and dirtyRegionOffset().

void QAbstractItemView::setIndexWidget(const QModelIndex &index, QWidget *widget)

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., if you pass the root index), this function will do nothing.

The given widget's 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.

If index widget A is replaced with index widget B, index widget A will be deleted. For example, in the code snippet below, the QLineEdit object will be deleted.

setIndexWidget(index, new QLineEdit);
...
setIndexWidget(index, new QTextEdit);

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 QStyledItemDelegate instead.

This function was introduced in Qt 4.1.

See also indexWidget() and Delegate Classes.

void QAbstractItemView::setItemDelegate(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. 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 closeEditor() signal, and attempt to access, modify or close an editor that has already been closed.

See also itemDelegate().

void QAbstractItemView::setItemDelegateForColumn(int column, 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., itemDelegate()).

Any existing column delegate for column will be removed, but not deleted. 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 precedence 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 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 itemDelegateForColumn(), setItemDelegateForRow(), and itemDelegate().

void QAbstractItemView::setItemDelegateForRow(int row, 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., itemDelegate()).

Any existing row delegate for row will be removed, but not deleted. 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., this delegate) will take precedence 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 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 itemDelegateForRow(), setItemDelegateForColumn(), and itemDelegate().

[virtual] void QAbstractItemView::setModel(QAbstractItemModel *model)

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:

QItemSelectionModel *m = view->selectionModel();
view->setModel(new model);
delete m;

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.

See also model(), selectionModel(), and setSelectionModel().

[pure virtual protected] void QAbstractItemView::setSelection(const QRect &rect, QItemSelectionModel::SelectionFlags flags)

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

When implementing your own itemview setSelection should call selectionModel()->select(selection, flags) where selection is either an empty QModelIndex or a QItemSelection that contains all items that are contained in rect.

See also selectionCommand() and selectedIndexes().

[virtual] void QAbstractItemView::setSelectionModel(QItemSelectionModel *selectionModel)

Sets the current selection model to the given selectionModel.

Note that, if you call setModel() after this function, the given selectionModel will be replaced by one created by the view.

Note: 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 deleteLater() function to explicitly delete it.

See also selectionModel(), setModel(), and clearSelection().

[protected] void QAbstractItemView::setState(QAbstractItemView::State state)

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

See also state().

[virtual] int QAbstractItemView::sizeHintForColumn(int column) const

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 sizeHintForRow().

QSize QAbstractItemView::sizeHintForIndex(const QModelIndex &index) const

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

See also sizeHintForRow() and sizeHintForColumn().

[virtual] int QAbstractItemView::sizeHintForRow(int row) const

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. the returned value is the maximum height among the items. Note that to control the height of a row, you must reimplement the 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 sizeHintForColumn().

[virtual protected] void QAbstractItemView::startDrag(Qt::DropActions supportedActions)

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