Detailed Description

The QAbstractItemModel class provides the abstract interface for item model classes.

The QAbstractItemModel class defines the standard interface that item models must use to be able to interoperate with other components in the model/view architecture. It is not supposed to be instantiated directly. Instead, you should subclass it to create new models.

The QAbstractItemModel class is one of the Model/View Classes and is part of Qt's model/view framework.

If you need a model to use with a QListView or a QTableView, you should consider subclassing QAbstractListModel or QAbstractTableModel instead of this class.

The underlying data model is exposed to views and delegates as a hierarchy of tables. If you do not make use of the hierarchy, then the model is a simple table of rows and columns. Each item has a unique index specified by a QModelIndex.

Every item of data that can be accessed via a model has an associated model index. You can obtain this model index using the index() function. Each index may have a sibling() index; child items have a parent() index.

Each item has a number of data elements associated with it and they can be retrieved by specifying a role (see Qt::ItemDataRole) to the model's data() function. Data for all available roles can be obtained at the same time using the itemData() function.

Data for each role is set using a particular Qt::ItemDataRole. Data for individual roles are set individually with setData(), or they can be set for all roles with setItemData().

Items can be queried with flags() (see Qt::ItemFlag) to see if they can be selected, dragged, or manipulated in other ways.

If an item has child objects, hasChildren() returns true for the corresponding index.

The model has a rowCount() and a columnCount() for each level of the hierarchy. Rows and columns can be inserted and removed with insertRows(), insertColumns(), removeRows(), and removeColumns().

The model emits signals to indicate changes. For example, dataChanged() is emitted whenever items of data made available by the model are changed. Changes to the headers supplied by the model cause headerDataChanged() to be emitted. If the structure of the underlying data changes, the model can emit layoutChanged() to indicate to any attached views that they should redisplay any items shown, taking the new structure into account.

The items available through the model can be searched for particular data using the match() function.

To sort the model, you can use sort().

Subclassing

Note: Some general guidelines for subclassing models are available in the Model Subclassing Reference.

When subclassing QAbstractItemModel, at the very least you must implement index(), parent(), rowCount(), columnCount(), and data(). These functions are used in all read-only models, and form the basis of editable models.

You can also reimplement hasChildren() to provide special behavior for models where the implementation of rowCount() is expensive. This makes it possible for models to restrict the amount of data requested by views, and can be used as a way to implement lazy population of model data.

To enable editing in your model, you must also implement setData(), and reimplement flags() to ensure that ItemIsEditable is returned. You can also reimplement headerData() and setHeaderData() to control the way the headers for your model are presented.

The dataChanged() and headerDataChanged() signals must be emitted explicitly when reimplementing the setData() and setHeaderData() functions, respectively.

Custom models need to create model indexes for other components to use. To do this, call createIndex() with suitable row and column numbers for the item, and an identifier for it, either as a pointer or as an integer value. The combination of these values must be unique for each item. Custom models typically use these unique identifiers in other reimplemented functions to retrieve item data and access information about the item's parents and children. See the Simple Tree Model Example for more information about unique identifiers.

It is not necessary to support every role defined in Qt::ItemDataRole. Depending on the type of data contained within a model, it may only be useful to implement the data() function to return valid information for some of the more common roles. Most models provide at least a textual representation of item data for the Qt::DisplayRole, and well-behaved models should also provide valid information for the Qt::ToolTipRole and Qt::WhatsThisRole. Supporting these roles enables models to be used with standard Qt views. However, for some models that handle highly-specialized data, it may be appropriate to provide data only for user-defined roles.

Models that provide interfaces to resizable data structures can provide implementations of insertRows(), removeRows(), insertColumns(),and removeColumns(). When implementing these functions, it is important to notify any connected views about changes to the model's dimensions both before and after they occur:

An insertRows() implementation must call beginInsertRows() before inserting new rows into the data structure, and endInsertRows() immediately afterwards.

An insertColumns() implementation must call beginInsertColumns() before inserting new columns into the data structure, and endInsertColumns() immediately afterwards.

A removeRows() implementation must call beginRemoveRows() before the rows are removed from the data structure, and endRemoveRows() immediately afterwards.

A removeColumns() implementation must call beginRemoveColumns() before the columns are removed from the data structure, and endRemoveColumns() immediately afterwards.

The private signals that these functions emit give attached components the chance to take action before any data becomes unavailable. The encapsulation of the insert and remove operations with these begin and end functions also enables the model to manage persistent model indexes correctly. If you want selections to be handled properly, you must ensure that you call these functions. If you insert or remove an item with children, you do not need to call these functions for the child items. In other words, the parent item will take care of its child items.

To create models that populate incrementally, you can reimplement fetchMore() and canFetchMore(). If the reimplementation of fetchMore() adds rows to the model, beginInsertRows() and endInsertRows() must be called.

Constructor & Destructor Documentation

QtCore.QAbstractItemModel.QAbstractItemModel ( System.Type  dummy )

protected

QtCore.QAbstractItemModel.QAbstractItemModel

(

QObject

parent = null

)

Constructs an abstract item model with the given parent.

Member Function Documentation

new void QtCore.QAbstractItemModel.BeginInsertColumns ( QModelIndex  parent, int  first, int  last  )

protected

Begins a column insertion operation.

When reimplementing insertColumns() in a subclass, you must call this function before inserting data into the model's underlying data store.

The parent index corresponds to the parent into which the new columns are inserted; first and last are the column numbers of the new columns will have after they have been inserted.

Specify the first and last column numbers for the span of columns you want to insert into an item in a model.For example, as shown in the diagram, we insert three columns before column 4, so first is 4 and last is 6:

beginInsertColumns(parent, 4, 6);

This inserts the three new columns as columns 4, 5, and 6.

To append columns, insert them after the last column.For example, as shown in the diagram, we append three columns to a collection of six existing columns (ending in column 5), so first is 6 and last is 8:

beginInsertColumns(parent, 6, 8);

This appends the two new columns as columns 6, 7, and 8.

new void QtCore.QAbstractItemModel.BeginInsertRows ( QModelIndex  parent, int  first, int  last  )

protected

Begins a row insertion operation.

When reimplementing insertRows() in a subclass, you must call this function before inserting data into the model's underlying data store.

The parent index corresponds to the parent into which the new rows are inserted; first and last are the row numbers that the new rows will have after they have been inserted.

Specify the first and last row numbers for the span of rows you want to insert into an item in a model.For example, as shown in the diagram, we insert three rows before row 2, so first is 2 and last is 4:

beginInsertRows(parent, 2, 4);

This inserts the three new rows as rows 2, 3, and 4.

To append rows, insert them after the last row.For example, as shown in the diagram, we append two rows to a collection of 4 existing rows (ending in row 3), so first is 4 and last is 5:

beginInsertRows(parent, 4, 5);

This appends the two new rows as rows 4 and 5.

new bool QtCore.QAbstractItemModel.BeginMoveColumns ( QModelIndex  sourceParent, int  sourceFirst, int  sourceLast, QModelIndex  destinationParent, int  destinationColumn  )

protected

Begins a column move operation.

When reimplementing a subclass, this method simplifies moving entities in your model. This method is responsible for moving persistent indexes in the model, which you would otherwise be required to do yourself. Using beginMoveRows and endMoveRows is an alternative to emitting layoutAboutToBeChanged and layoutChanged directly along with changePersistentIndexes. layoutAboutToBeChanged is emitted by this method for compatibility reasons.

The sourceParent index corresponds to the parent from which the columns are moved; sourceFirst and sourceLast are the first and last column numbers of the columns to be moved. The destinationParent index corresponds to the parent into which those columns are moved. The destinationChild is the column to which the columns will be moved. That is, the index at column sourceFirst in sourceParent will become column destinationChild in destinationParent, followed by all other columns up to sourceLast.

However, when moving columns down in the same parent (sourceParent and destinationParent are equal), the columnss will be placed before the destinationChild index. That is, if you wish to move columns 0 and 1 so they will become columns 1 and 2, destinationChild should be 3. In this case, the new index for the source column i (which is between sourceFirst and sourceLast) is equal to (destinationChild-sourceLast-1+i).

Note that if sourceParent and destinationParent are the same, you must ensure that the destinationChild is not within the range of sourceFirst and sourceLast + 1. You must also ensure that you do not attempt to move a column to one of its own children or ancestors. This method returns false if either condition is true, in which case you should abort your move operation.

This function was introduced in Qt 4.6.

See also endMoveColumns().

new bool QtCore.QAbstractItemModel.BeginMoveRows ( QModelIndex  sourceParent, int  sourceFirst, int  sourceLast, QModelIndex  destinationParent, int  destinationRow  )

protected

Begins a row move operation.

When reimplementing a subclass, this method simplifies moving entities in your model. This method is responsible for moving persistent indexes in the model, which you would otherwise be required to do yourself. Using beginMoveRows and endMoveRows is an alternative to emitting layoutAboutToBeChanged and layoutChanged directly along with changePersistentIndexes. layoutAboutToBeChanged is emitted by this method for compatibility reasons.

The sourceParent index corresponds to the parent from which the rows are moved; sourceFirst and sourceLast are the first and last row numbers of the rows to be moved. The destinationParent index corresponds to the parent into which those rows are moved. The destinationChild is the row to which the rows will be moved. That is, the index at row sourceFirst in sourceParent will become row destinationChild in destinationParent, followed by all other rows up to sourceLast.

However, when moving rows down in the same parent (sourceParent and destinationParent are equal), the rows will be placed before the destinationChild index. That is, if you wish to move rows 0 and 1 so they will become rows 1 and 2, destinationChild should be 3. In this case, the new index for the source row i (which is between sourceFirst and sourceLast) is equal to (destinationChild-sourceLast-1+i).

Note that if sourceParent and destinationParent are the same, you must ensure that the destinationChild is not within the range of sourceFirst and sourceLast + 1. You must also ensure that you do not attempt to move a row to one of its own children or ancestors. This method returns false if either condition is true, in which case you should abort your move operation.

Specify the first and last row numbers for the span of rows in the source parent you want to move in the model. Also specify the row in the destination parent to move the span to.For example, as shown in the diagram, we move three rows from row 2 to 4 in the source, so sourceFirst is 2 and sourceLast is 4. We move those items to above row 2 in the destination, so destinationChild is 2.

beginMoveRows(sourceParent, 2, 4, destinationParent, 2);

This moves the three rows rows 2, 3, and 4 in the source to become 2, 3 and 4 in the destination. Other affected siblings are displaced accordingly.

To append rows to another parent, move them to after the last row.For example, as shown in the diagram, we move three rows to a collection of 6 existing rows (ending in row 5), so destinationChild is 6:

beginMoveRows(sourceParent, 2, 4, destinationParent, 6);

This moves the target rows to the end of the target parent as 6, 7 and 8.

To move rows within the same parent, specify the row to move them to.For example, as shown in the diagram, we move one item from row 2 to row 0, so sourceFirst and sourceLast are 2 and destinationChild is 0.

beginMoveRows(parent, 2, 2, parent, 0);

Note that other rows may be displaced accordingly. Note also that when moving items within the same parent you should not attempt invalid or no-op moves. In the above example, item 2 is at row 2 before the move, so it can not be moved to row 2 (where it is already) or row 3 (no-op as row 3 means above row 3, where it is already)

To move rows within the same parent, specify the row to move them to.For example, as shown in the diagram, we move one item from row 2 to row 4, so sourceFirst and sourceLast are 2 and destinationChild is 4.

beginMoveRows(parent, 2, 2, parent, 4);

Note that other rows may be displaced accordingly.

new void QtCore.QAbstractItemModel.BeginRemoveColumns ( QModelIndex  parent, int  first, int  last  )

protected

Begins a column removal operation.

When reimplementing removeColumns() in a subclass, you must call this function before removing data from the model's underlying data store.

The parent index corresponds to the parent from which the new columns are removed; first and last are the column numbers of the first and last columns to be removed.

Specify the first and last column numbers for the span of columns you want to remove from an item in a model.For example, as shown in the diagram, we remove the three columns from column 4 to column 6, so first is 4 and last is 6:

beginRemoveColumns(parent, 4, 6);

new void QtCore.QAbstractItemModel.BeginRemoveRows ( QModelIndex  parent, int  first, int  last  )

protected

Begins a row removal operation.

When reimplementing removeRows() in a subclass, you must call this function before removing data from the model's underlying data store.

The parent index corresponds to the parent from which the new rows are removed; first and last are the row numbers of the rows to be removed.

Specify the first and last row numbers for the span of rows you want to remove from an item in a model.For example, as shown in the diagram, we remove the two rows from row 2 to row 3, so first is 2 and last is 3:

beginRemoveRows(parent, 2, 3);

new void QtCore.QAbstractItemModel.BeginResetModel ( )

protected

Begins a model reset operation.

A reset operation resets the model to its current state in any attached views.

Note: Any views attached to this model will be reset as well.

When a model is reset it means that any previous data reported from the model is now invalid and has to be queried for again. This also means that the current item and any selected items will become invalid.

When a model radically changes its data it can sometimes be easier to just call this function rather than emit dataChanged() to inform other components when the underlying data source, or its structure, has changed.

You must call this function before resetting any internal data structures in your model or proxy model.

This function was introduced in Qt 4.6.

See also modelAboutToBeReset(), modelReset(), and endResetModel().

virtual QModelIndex QtCore.QAbstractItemModel.Buddy ( QModelIndex  index )

virtual

Returns a model index for the buddy of the item represented by index. When the user wants to edit an item, the view will call this function to check whether another item in the model should be edited instead. Then, the view will construct a delegate using the model index returned by the buddy item.

The default implementation of this function has each item as its own buddy.

Reimplemented in QtGui.QSortFilterProxyModel, and QtGui.QAbstractProxyModel.

virtual bool QtCore.QAbstractItemModel.CanFetchMore ( QModelIndex  parent )

virtual

Returns true if there is more data available for parent; otherwise returns false.

The default implementation always returns false.

If canFetchMore() returns true, QAbstractItemView will call fetchMore(). However, the fetchMore() function is only called when the model is being populated incrementally.

See also fetchMore().

Reimplemented in QtGui.QSortFilterProxyModel, QtGui.QFileSystemModel, QtSql.QSqlQueryModel, and QtGui.QAbstractProxyModel.

new void QtCore.QAbstractItemModel.ChangePersistentIndex ( QModelIndex  from, QModelIndex  to  )

protected

Changes the QPersistentModelIndex that is equal to the given from model index to the given to model index.

If no persistent model index equal to the given from model index was found, nothing is changed.

See also persistentIndexList() and changePersistentIndexList().

new void QtCore.QAbstractItemModel.ChangePersistentIndexList ( System.Collections.Generic.List< QModelIndex >  from, System.Collections.Generic.List< QModelIndex >  to  )

protected

Changes the QPersistentModelIndexes that is equal to the indexes in the given from model index list to the given to model index list.

If no persistent model indexes equal to the indexes in the given from model index list was found, nothing is changed.

This function was introduced in Qt 4.1.

See also persistentIndexList() and changePersistentIndex().

new QModelIndex QtCore.QAbstractItemModel.CreateIndex ( int  row, int  column  )

protected

Creates a model index for the given row and column with the internal pointer ptr.

When using a QSortFilterProxyModel, its indexes have their own internal pointer. It is not advisable to access this internal pointer outside of the model. Use the data() function instead.

This function provides a consistent interface that model subclasses must use to create model indexes.

new QModelIndex QtCore.QAbstractItemModel.CreateIndex ( int  row, int  column, int  id  )

protected

Creates a model index for the given row and column with the internal pointer ptr.

When using a QSortFilterProxyModel, its indexes have their own internal pointer. It is not advisable to access this internal pointer outside of the model. Use the data() function instead.

This function provides a consistent interface that model subclasses must use to create model indexes.

new QModelIndex QtCore.QAbstractItemModel.CreateIndex ( int  row, int  column, uint  id  )

protected

Creates a model index for the given row and column with the internal pointer ptr.

When using a QSortFilterProxyModel, its indexes have their own internal pointer. It is not advisable to access this internal pointer outside of the model. Use the data() function instead.

This function provides a consistent interface that model subclasses must use to create model indexes.

override void QtCore.QAbstractItemModel.CreateProxy ( )

virtual

Reimplemented from QtCore.QObject.

Reimplemented in QtGui.QStringListModel, QtGui.QStandardItemModel, QtGui.QSortFilterProxyModel, QtGui.QProxyModel, QtGui.QFileSystemModel, QtGui.QDirModel, QtSql.QSqlTableModel, QtSql.QSqlRelationalTableModel, QtSql.QSqlQueryModel, QtCore.QAbstractTableModel, QtCore.QAbstractListModel, and QtGui.QAbstractProxyModel.

abstract object QtCore.QAbstractItemModel.Data ( QModelIndex  index, int  role = (int) Qt.ItemDataRole.DisplayRole  )

pure virtual

Returns the data stored under the given role for the item referred to by the index.

Note: If you do not have a value to return, return an invalid QVariant instead of returning 0.

See also Qt::ItemDataRole, setData(), and headerData().

Implemented in QtGui.QStringListModel, QtGui.QStandardItemModel, QtGui.QSortFilterProxyModel, QtGui.QProxyModel, QtGui.QFileSystemModel, QtGui.QDirModel, QtSql.QSqlTableModel, QtSql.QSqlRelationalTableModel, QtSql.QSqlQueryModel, and QtGui.QAbstractProxyModel.

new bool QtCore.QAbstractItemModel.DecodeData ( int  row, int  column, QModelIndex  parent, QDataStream  stream  )

protected

new void QtCore.QAbstractItemModel.Dispose

(

)

virtual bool QtCore.QAbstractItemModel.DropMimeData ( QMimeData  data, Qt.DropAction  action, int  row, int  column, QModelIndex  parent  )

virtual

Handles the data supplied by a drag and drop operation that ended with the given action.

Returns true if the data and action can be handled by the model; otherwise returns false.

The specified row, column and parent indicate the location of an item in the model where the operation ended. It is the responsibility of the model to complete the action at the correct location.

For instance, a drop action on an item in a QTreeView can result in new items either being inserted as children of the item specified by row, column, and parent, or as siblings of the item.

When row and column are -1 it means that the dropped data should be considered as dropped directly on parent. Usually this will mean appending the data as child items of parent. If row and column are greater than or equal zero, it means that the drop occurred just before the specified row and column in the specified parent.

See also supportedDropActions() and Using drag and drop with item views.

virtual

Returns a list of indexes for the items in the column of the start index where data stored under the given role matches the specified value. The way the search is performed is defined by the flags given. The list that is returned may be empty.

The search begins from the start index, and continues until the number of matching data items equals hits, the search reaches the last row, or the search reaches start again - depending on whether MatchWrap is specified in flags. If you want to search for all matching items, use hits = -1.

By default, this function will perform a wrapping, string-based comparison on all items, searching for items that begin with the search term specified by value.

Note: The default implementation of this function only searches columns. Reimplement this function to include a different search behavior.

new void QtCore.QAbstractItemModel.OnDataChanged ( QModelIndex  topLeft, QModelIndex  bottomRight  )

protected

This signal is emitted whenever the data in an existing item changes.

If the items are of the same parent, the affected ones are those between topLeft and bottomRight inclusive. If the items do not have the same parent, the behavior is undefined.

When reimplementing the setData() function, this signal must be emitted explicitly.

See also headerDataChanged(), setData(), and layoutChanged().

new void QtCore.QAbstractItemModel.OnHeaderDataChanged ( Qt.Orientation  orientation, int  first, int  last  )

protected

This signal is emitted whenever a header is changed. The orientation indicates whether the horizontal or vertical header has changed. The sections in the header from the first to the last need to be updated.

When reimplementing the setHeaderData() function, this signal must be emitted explicitly.

If you are changing the number of columns or rows you do not need to emit this signal, but use the begin/end functions (refer to the section on subclassing in the QAbstractItemModel class description for details).

See also headerData(), setHeaderData(), and dataChanged().

new void QtCore.QAbstractItemModel.OnLayoutAboutToBeChanged ( )

protected

This signal is emitted just before the layout of a model is changed. Components connected to this signal use it to adapt to changes in the model's layout.

Subclasses should update any persistent model indexes after emitting layoutAboutToBeChanged().

This function was introduced in Qt 4.2.

See also layoutChanged() and changePersistentIndex().

new void QtCore.QAbstractItemModel.OnLayoutChanged ( )

protected

This signal is emitted whenever the layout of items exposed by the model has changed; for example, when the model has been sorted. When this signal is received by a view, it should update the layout of items to reflect this change.

When subclassing QAbstractItemModel or QAbstractProxyModel, ensure that you emit layoutAboutToBeChanged() before changing the order of items or altering the structure of the data you expose to views, and emit layoutChanged() after changing the layout.

Subclasses should update any persistent model indexes before emitting layoutChanged(). In other words, when the structure changes:

emit layoutAboutToBeChanged

Remember the QModelIndex that will change

Update your internal data

Call changePersistentIndex()

emit layoutChanged

See also layoutAboutToBeChanged(), dataChanged(), headerDataChanged(), modelReset(), and changePersistentIndex().

new QObject QtCore.QAbstractItemModel.Parent

(

)

Returns the parent of the model item with the given index. If the item has no parent, an invalid QModelIndex is returned.

A common convention used in models that expose tree data structures is that only items in the first column have children. For that case, when reimplementing this function in a subclass the column of the returned QModelIndex would be 0.

When reimplementing this function in a subclass, be careful to avoid calling QModelIndex member functions, such as QModelIndex::parent(), since indexes belonging to your model will simply call your implementation, leading to infinite recursion.

See also createIndex().

abstract QModelIndex QtCore.QAbstractItemModel.Parent ( QModelIndex  child )
