Detailed Description

A proxy model that proxies its source model unmodified.

A WIdentityProxyModel simply forwards the structure of the source model, without any transformation. WIdentityProxyModel can be used as a base class for implementing proxy models that reimplement data(), but retain all other characteristics of the source model.

int Wt::WIdentityProxyModel::columnCount

(

const WModelIndex &

parent = WModelIndex()

)

const [virtual]

Returns the number of columns.

Translates the parent index to the source model, and returns the number of columns of the source model.

Implements Wt::WAbstractItemModel.

WModelIndex Wt::WIdentityProxyModel::index	(	int	row,
		int	column,
		const WModelIndex &	parent = WModelIndex()
	)		const [virtual]

Returns the child index for the given row and column.

Implements Wt::WAbstractItemModel.

bool Wt::WIdentityProxyModel::insertColumns	(	int	column,
		int	count,
		const WModelIndex &	parent = WModelIndex()
	)		[virtual]

Inserts one or more columns.

Inserts count columns at column column in the source model.

Forwards the result indicating success from the source model.

Reimplemented from Wt::WAbstractProxyModel.

bool Wt::WIdentityProxyModel::insertRows	(	int	row,
		int	count,
		const WModelIndex &	parent = WModelIndex()
	)		[virtual]

Inserts one or more rows.

Inserts count rows at row row in the source model.

Forwards the result indicating success from the source model.

Reimplemented from Wt::WAbstractItemModel.

WModelIndex Wt::WIdentityProxyModel::mapFromSource

(

const WModelIndex &

sourceIndex

)

const [virtual]

Maps a proxy model index to the source model.

Returns a model index with the same row and column as the source index. The parent index is mapped recursively.

Implements Wt::WAbstractProxyModel.

WModelIndex Wt::WIdentityProxyModel::mapToSource

(

const WModelIndex &

proxyIndex

)

const [virtual]

Maps a source model index to the proxy model.

Returns a model index with the same row and column as the proxy index. The parent index is mapped recursively.

Implements Wt::WAbstractProxyModel.

WModelIndex Wt::WIdentityProxyModel::parent

(

const WModelIndex &

child

)

const [virtual]

Returns the parent for a model index.

Translates the child index to the source model, and translates its parent back to this proxy model.

Implements Wt::WAbstractItemModel.

bool Wt::WIdentityProxyModel::removeColumns	(	int	column,
		int	count,
		const WModelIndex &	parent = WModelIndex()
	)		[virtual]

Removes columns.

Removes count columns at column column in the source model.

Forwards the result indicating success from the source model.

Reimplemented from Wt::WAbstractProxyModel.

bool Wt::WIdentityProxyModel::removeRows	(	int	row,
		int	count,
		const WModelIndex &	parent = WModelIndex()
	)		[virtual]

Removes rows.

Removes count rows at row row in the source model.

Forwards the result indicating success from the source model.

Reimplemented from Wt::WAbstractItemModel.

int Wt::WIdentityProxyModel::rowCount

(

const WModelIndex &

parent = WModelIndex()

)

const [virtual]

Returns the number of rows.

Translates the parent index to the source model, and returns the number of rows of the source model.

Implements Wt::WAbstractItemModel.

bool Wt::WIdentityProxyModel::setHeaderData	(	int	section,
		Orientation	orientation,
		const boost::any &	value,
		int	role = EditRole
	)		[virtual]

Set header data for a column or row.

Sets the header data for a column or row in the source model.

Forwards the result indicating success from the source model.

Reimplemented from Wt::WAbstractItemModel.

void Wt::WIdentityProxyModel::setSourceModel

(

WAbstractItemModel *

sourceModel

)

[virtual]

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 forwarded to the proxy model.

Reimplemented from Wt::WAbstractProxyModel.
