Detailed Description

A proxy model for Wt's item models that provides batch editing.

This proxy model presents data from a source model, and caches any editing operation without affecting the underlying source model, until commitAll() or revertAll() is called. In this way, you can commit all the editing in batch to the underlying source model, only when the user confirms the changes.

All editing operations are supported:

changing data (setData())
inserting and removing rows (insertRows() and removeRows())
inserting and removing columns (insertColumns() and removeColumns())

The model supports both simple tabular models, as well as hierarchical (tree-like / treetable-like) models, with children under items in the first column.

Default values for a newly inserted row can be set using setNewRowData() and flags for its items using setNewRowFlags().

Member Function Documentation

◆ columnCount()

int Wt::WBatchEditProxyModel::columnCount ( const WModelIndex & parent = WModelIndex() ) const

overridevirtual

Returns the number of columns.

This returns the number of columns at index parent.

See also: rowCount()

Implements Wt::WAbstractItemModel.

◆ commitAll()

void Wt::WBatchEditProxyModel::commitAll ( )

Commits changes.

This commits all changes to the source model.

See also: revertAll()

◆ data() [1/3]

cpp17::any Wt::WBatchEditProxyModel::data	(	const WModelIndex &	index,
		ItemDataRole	role = `ItemDataRole::Display`
	)		const

overridevirtual

Returns the data at a specific model index.

The default proxy implementation translates the index to the source model, and calls sourceModel()->data() with this index.

Reimplemented from Wt::WAbstractProxyModel.

◆ data() [2/3]

virtual cpp17::any Wt::WAbstractItemModel::data

Returns data at a specified model index for the given role.

You should check the role to decide what data to return. Usually a View class will ask for data for several roles which affect not only the contents (Wt::ItemDataRole::Display) but also icons (Wt::ItemDataRole::Decoration), URLs (Wt::ItemDataRole::Link), and other visual aspects. If your item does not specify data for a particular role, it should simply return a Wt::cpp17::any().

See also: flags(), headerData(), setData()

◆ data() [3/3]

cpp17::any Wt::WAbstractItemModel::data

Returns the data item at the given column and row.

This is a convenience method, and is equivalent to:

index(row, column, parent).data(role)

Wt::WBatchEditProxyModel::index

virtual WModelIndex index(int row, int column, const WModelIndex &parent=WModelIndex()) const override

Returns the child index for the given row and column.

Definition: WBatchEditProxyModel.C:319

Wt::WBatchEditProxyModel::parent

virtual WModelIndex parent(const WModelIndex &index) const override

Returns the parent for a model index.

Definition: WBatchEditProxyModel.C:326

Wt::WModelIndex::data

cpp17::any data(ItemDataRole role=ItemDataRole::Display) const

Returns data in the model at this index.

Definition: WModelIndex.C:44

See also: index(), data()

◆ flags()

WFlags< ItemFlag > Wt::WBatchEditProxyModel::flags ( const WModelIndex & index ) const

overridevirtual

Returns the flags for an item.

The default proxy implementation calls sourceModel()->flags(mapToSource(index))

Reimplemented from Wt::WAbstractProxyModel.

◆ headerData()

cpp17::any Wt::WBatchEditProxyModel::headerData	(	int	section,
		Orientation	orientation = `Orientation::Horizontal`,
		ItemDataRole	role = `ItemDataRole::Display`
	)		const

overridevirtual

Returns the row or column header data.

The default proxy implementation constructs a dummy WModelIndex with the row set to 0 and column set to section if the orientation is Wt::Orientation::Horizontal, or with the row set to section and the column set to 0 if the orientation is Wt::Orientation::Vertical.

The resulting section that is forwarded to sourceModel()->headerData() depends on how the WModelIndex is transformed with mapToSource().

Reimplemented from Wt::WAbstractProxyModel.

◆ index()

WModelIndex Wt::WBatchEditProxyModel::index	(	int	row,
		int	column,
		const WModelIndex &	parent = `WModelIndex()`
	)		const

overridevirtual

Returns the child index for the given row and column.

When implementing this method, you can use createIndex() to create an index that corresponds to the item at row and column within parent.

If the location is invalid (out of bounds at the parent), then an invalid index must be returned.

See also: parent()

Implements Wt::WAbstractItemModel.

◆ insertColumns()

bool Wt::WBatchEditProxyModel::insertColumns	(	int	column,
		int	count,
		const WModelIndex &	parent = `WModelIndex()`
	)

overridevirtual

Inserts one or more columns.

The default proxy implementation calls sourceModel()->insertColumns(column, count, parent)

Reimplemented from Wt::WAbstractProxyModel.

◆ insertRows()

bool Wt::WBatchEditProxyModel::insertRows	(	int	row,
		int	count,
		const WModelIndex &	parent = `WModelIndex()`
	)

overridevirtual

Inserts one or more rows.

In models that support row insertion, this inserts count rows, starting at row, and returns true if the operation was successful. The new rows are inserted under parent.

If parent had no children, then a single column is added with count rows.

The default implementation returns false.

The model implementation must call beginInsertRows() and endInsertRows() before and after the operation whenever its geometry is changed by inserting rows. This emits signals for views to properly react to these changes.

See also: insertColumns(), removeRows(), beginInsertRows(), endInsertRows()

Reimplemented from Wt::WAbstractItemModel.

◆ isDirty()

bool Wt::WBatchEditProxyModel::isDirty ( ) const

Returns whether changes have not yet been committed.

Returns whether have been made to the proxy model, which could be committed using commitAll() or reverted using revertAll().

◆ mapFromSource()

WModelIndex Wt::WBatchEditProxyModel::mapFromSource ( const WModelIndex & sourceIndex ) const

overridevirtual

Maps a source model index to the proxy model.

This method returns a model index in the proxy model that corresponds to the model index sourceIndex in the source model. This method must only be implemented for source model indexes that are mapped and thus are the result of mapToSource().

See also: mapToSource()

Implements Wt::WAbstractProxyModel.

◆ mapToSource()

WModelIndex Wt::WBatchEditProxyModel::mapToSource ( const WModelIndex & proxyIndex ) const

overridevirtual

Maps a proxy model index to the source model.

This method returns a model index in the source model that corresponds to the proxy model index proxyIndex.

See also: mapFromSource()

Implements Wt::WAbstractProxyModel.

◆ parent()

WModelIndex Wt::WBatchEditProxyModel::parent ( const WModelIndex & index ) const

overridevirtual

Returns the parent for a model index.

An implementation should use createIndex() to create a model index that corresponds to the parent of a given index.

Note that the index itself may be stale (referencing a row/column within the parent that is outside the model geometry), but its parent (identified by the WModelIndex::internalPointer()) is referencing an existing parent. A stale index can only be used while the model geometry is being updated, i.e. during the emission of the corresponding [rows/columns](Being)[Removed/Inserted]() signals.

See also: index()

Implements Wt::WAbstractItemModel.

◆ removeColumns()

bool Wt::WBatchEditProxyModel::removeColumns	(	int	column,
		int	count,
		const WModelIndex &	parent = `WModelIndex()`
	)

overridevirtual

Removes columns.

The default proxy implementation calls sourceModel()->removeColumns(column, count, parent)

Reimplemented from Wt::WAbstractProxyModel.

◆ removeRows()

bool Wt::WBatchEditProxyModel::removeRows	(	int	row,
		int	count,
		const WModelIndex &	parent = `WModelIndex()`
	)

overridevirtual

Removes rows.

Returns true if the operation was successful.

The default implementation returns false.

The model implementation must call beginRemoveRows() and endRemoveRows() before and after the operation whenever its geometry is changed by removing rows. This emits signals for views to properly react to these changes.

See also: removeColumns(), insertRows(), beginRemoveRows(), endRemoveRows()

Reimplemented from Wt::WAbstractItemModel.

◆ revertAll()

void Wt::WBatchEditProxyModel::revertAll ( )

Reverts changes.

This reverts all changes.

See also: commitAll()

◆ rowCount()

int Wt::WBatchEditProxyModel::rowCount ( const WModelIndex & parent = WModelIndex() ) const

overridevirtual

Returns the number of rows.

This returns the number of rows at index parent.

See also: columnCount()

Implements Wt::WAbstractItemModel.

◆ setData() [1/3]

virtual bool Wt::WAbstractItemModel::setData

Sets data at the given model index.

Returns true if the operation was successful.

The default implementation returns false.

The model implementation must emit the dataChanged() signal after data was changed.

See also: data()

◆ setData() [2/3]

bool Wt::WBatchEditProxyModel::setData	(	const WModelIndex &	index,
		const cpp17::any &	value,
		ItemDataRole	role = `ItemDataRole::Edit`
	)

overridevirtual

Sets item data.

The default implementation will copy Wt::ItemDataRole::Edit data to Wt::ItemDataRole::Display. You may want to specialize the model to provide a more specialized editing behaviour.

Reimplemented from Wt::WAbstractProxyModel.

◆ setData() [3/3]

bool Wt::WAbstractItemModel::setData

Sets data at the given row and column.

This is a convience method, and is equivalent to:

setData(index(row, column, parent), value, role);

Wt::WBatchEditProxyModel::setData

virtual bool setData(const WModelIndex &index, const cpp17::any &value, ItemDataRole role=ItemDataRole::Edit)

Sets data at the given model index.

Returns true if the operation was successful.

See also: setData(), index()

◆ setDirtyIndication()

void Wt::WBatchEditProxyModel::setDirtyIndication	(	ItemDataRole	role,
		const cpp17::any &	data
	)

Configures data used to indicate a modified item.

This sets data for item data role role to be returned by data() for an item that is dirty (e.g. because it belongs to a newly inserted row/column, or because new data has been set for it.

When role is Wt::ItemDataRole::StyleClass, the style class is appended to any style already returned by the source model or set by setNewRowData().

By default there is no dirty indication.

◆ setHeaderData() [1/2]

bool Wt::WAbstractItemModel::setHeaderData

Sets column header data.

Returns true if the operation was successful.

See also: setHeaderData(int, Orientation, const cpp17::any&, int)

◆ setHeaderData() [2/2]

virtual bool Wt::WAbstractItemModel::setHeaderData

Sets header data for a column or row.

Returns true if the operation was successful.

See also: headerData()

◆ setNewRowData()

void Wt::WBatchEditProxyModel::setNewRowData	(	int	column,
		const cpp17::any &	data,
		ItemDataRole	role = `ItemDataRole::Display`
	)

Sets default data for a newly inserted row.

You can use this method to initialize data for a newly inserted row.

◆ setNewRowFlags()

void Wt::WBatchEditProxyModel::setNewRowFlags	(	int	column,
		WFlags< ItemFlag >	flags
	)

Sets the item flags for items in a newly inserted row.

By default, flags() will return ItemFlag::Selectable.

◆ setSourceModel()

void Wt::WBatchEditProxyModel::setSourceModel ( const std::shared_ptr< WAbstractItemModel > & sourceModel )

overridevirtual

Sets the source model.

The source model provides the actual data for the proxy model.

Ownership of the source model is not transferred.

All signals of the source model are propagated to the proxy model.

Reimplemented from Wt::WAbstractProxyModel.

◆ sort()

void Wt::WBatchEditProxyModel::sort	(	int	column,
		SortOrder	order = `SortOrder::Ascending`
	)

overridevirtual

Sorts the model according to a particular column.

If the model supports sorting, then it should emit the layoutAboutToBeChanged() signal, rearrange its items, and afterwards emit the layoutChanged() signal.

See also: layoutAboutToBeChanged(), layoutChanged()

Reimplemented from Wt::WAbstractItemModel.
