Detailed Description

Warning

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.
Ctrl+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 NoSelection .

The QAbstractItemView class is one of the Model/View Classes and is part of Qt’s 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:

def resizeEvent(self, event):
    horizontalScrollBar().setRange(0, realWidth - width())
    ...

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.

Note

If you inherit QAbstractItemView and intend to update the contents of the viewport, you should use viewport-> update() instead of update() as all painting operations take place on the viewport.

View Classes Model/View Programming QAbstractItemModel

class PySide6.QtWidgets.QAbstractItemView([parent=None])

Parameters:

parent – PySide6.QtWidgets.QWidget

Constructs an abstract item view with the given parent.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property PᅟySide6.QtWidgets.QAbstractItemView.alternatingRowColors: bool

This property holds whether to draw the background using alternating colors.

If this property is true, the item background will be drawn using QPalette::Base and QPalette::AlternateBase; otherwise the background will be drawn using the QPalette::Base color.

By default, this property is false.

Access functions:

• alternatingRowColors ()

• setAlternatingRowColors (enable)

property PᅟySide6.QtWidgets.QAbstractItemView.autoScroll: bool

This property holds whether autoscrolling in drag move events is enabled.

If this property is set to true (the default), the QAbstractItemView automatically scrolls the contents of the view if the user drags within 16 pixels of the viewport edge. If the current item changes, then the view will scroll automatically to ensure that the current item is fully visible.

This property only works if the viewport accepts drops. Autoscroll is switched off by setting this property to false.

Access functions:

• hasAutoScroll ()

• setAutoScroll (enable)

property PᅟySide6.QtWidgets.QAbstractItemView.autoScrollMargin: int

This property holds the size of the area when auto scrolling is triggered.

This property controls the size of the area at the edge of the viewport that triggers autoscrolling. The default value is 16 pixels.

Access functions:

• autoScrollMargin ()

• setAutoScrollMargin (margin)

property PᅟySide6.QtWidgets.QAbstractItemView.defaultDropAction: DropAction

This property holds the drop action that will be used by default in QAbstractItemView::drag().

If the property is not set, the drop action is CopyAction when the supported actions support CopyAction.

See also

showDropIndicator dragDropOverwriteMode

Access functions:

• defaultDropAction ()

• setDefaultDropAction (dropAction)

property PᅟySide6.QtWidgets.QAbstractItemView.dragDropMode: DragDropMode

This property holds the drag and drop event the view will act upon.

See also

showDropIndicator dragDropOverwriteMode

Access functions:

• dragDropMode ()

• setDragDropMode (behavior)

property PᅟySide6.QtWidgets.QAbstractItemView.dragDropOverwriteMode: bool

This property holds the view’s drag and drop behavior.

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.

Note: This is not intended to prevent overwriting of items. The model’s implementation of flags() should do that by not returning Qt::ItemIsDropEnabled.

See also

dragDropMode

Access functions:

• dragDropOverwriteMode ()

• setDragDropOverwriteMode (overwrite)

property PᅟySide6.QtWidgets.QAbstractItemView.dragEnabled: bool

This property is a selection of flags defined by EditTrigger , combined using the OR operator. The view will only initiate the editing of an item if the action performed is set in this property.

Access functions:

• editTriggers ()

• setEditTriggers (triggers)

property PᅟySide6.QtWidgets.QAbstractItemView.horizontalScrollMode: ScrollMode

PySide6.QtWidgets.QAbstractItemView.SelectionMode

This enum indicates how the view responds to user selections:

Constant	Description
QAbstractItemView.SingleSelection	When the user selects an item, any already-selected item becomes unselected. It is possible for the user to deselect the selected item by pressing the Ctrl key when clicking the selected item.
QAbstractItemView.ContiguousSelection	When the user selects an item in the usual way, the selection is cleared and the new item selected. However, if the user presses the Shift key while clicking on an item, all items between the current item and the clicked item are selected or unselected, depending on the state of the clicked item.
QAbstractItemView.ExtendedSelection	When the user selects an item in the usual way, the selection is cleared and the new item selected. However, if the user presses the Ctrl key when clicking on an item, the clicked item gets toggled and all other items are left untouched. If the user presses the Shift key while clicking on an item, all items between the current item and the clicked item are selected or unselected, depending on the state of the clicked item. Multiple items can be selected by dragging the mouse over them.
QAbstractItemView.MultiSelection	When the user selects an item in the usual way, the selection status of that item is toggled and the other items are left alone. Multiple items can be toggled by dragging the mouse over them.
QAbstractItemView.NoSelection	Items cannot be selected.

The most commonly used modes are SingleSelection and ExtendedSelection.

PySide6.QtWidgets.QAbstractItemView.setIndexWidget(index, widget)

Parameters:

• index – PySide6.QtCore.QModelIndex

• widget – PySide6.QtWidgets.QWidget

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

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, QLineEdit())
...
setIndexWidget(index, 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.

indexWidget() Delegate Classes

PySide6.QtWidgets.QAbstractItemView.setItemDelegate(delegate)

Parameters:

delegate – PySide6.QtWidgets.QAbstractItemDelegate

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()

PySide6.QtWidgets.QAbstractItemView.setItemDelegateForColumn(column, delegate)

Parameters:

• column – int

• delegate – PySide6.QtWidgets.QAbstractItemDelegate

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.

See also

itemDelegateForColumn() setItemDelegateForRow() itemDelegate()

PySide6.QtWidgets.QAbstractItemView.setItemDelegateForRow(row, delegate)

Parameters:

• row – int

• delegate – PySide6.QtWidgets.QAbstractItemDelegate

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.

PySide6.QtWidgets.QAbstractItemView.setModel(model)

Parameters:

model – PySide6.QtCore.QAbstractItemModel

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

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:

m = view.selectionModel()
view.setModel(model())
del 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.

model() selectionModel() setSelectionModel()

PySide6.QtWidgets.QAbstractItemView.setRootIndex(index)

Parameters:

index – PySide6.QtCore.QModelIndex

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

abstract PySide6.QtWidgets.QAbstractItemView.setSelection(rect, command)

Parameters:

• rect – PySide6.QtCore.QRect

• command – Combination of QItemSelectionModel.SelectionFlag

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.

PySide6.QtWidgets.QAbstractItemView.setSelectionModel(selectionModel)

Parameters:

selectionModel – PySide6.QtCore.QItemSelectionModel

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.
