eu.webtoolkit.jwt.WIdentityProxyModel

public class WIdentityProxyModel
extends WAbstractProxyModel

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 WAbstractProxyModel#getData(), but retain all other characteristics of the source model.

Method Details

getColumnCount

public int getColumnCount(WModelIndex parent)

Returns the number of columns.

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

Specified by:

getColumnCount in class WAbstractItemModel

See Also:

WAbstractItemModel.getRowCount(WModelIndex parent)

getRowCount

public int getRowCount(WModelIndex parent)

Returns the number of rows.

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

Specified by:

getRowCount in class WAbstractItemModel

See Also:

WAbstractItemModel.getColumnCount(WModelIndex parent)

getParent

public WModelIndex getParent(WModelIndex child)

Returns the parent for a model index.

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

Specified by:

getParent in class WAbstractItemModel

See Also:

WAbstractItemModel.getIndex(int row, int column, WModelIndex parent)

getIndex

public WModelIndex getIndex(int row,
int column,
WModelIndex parent)

Returns the child index for the given row and column.

Specified by:

getIndex in class WAbstractItemModel

See Also:

WAbstractItemModel.getParent(WModelIndex index)

mapFromSource

public WModelIndex mapFromSource(WModelIndex sourceIndex)

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.

Specified by:

mapFromSource in class WAbstractProxyModel

See Also:

WAbstractProxyModel.mapToSource(WModelIndex proxyIndex)

mapToSource

public WModelIndex mapToSource(WModelIndex proxyIndex)

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.

Specified by:

mapToSource in class WAbstractProxyModel

See Also:

WAbstractProxyModel.mapFromSource(WModelIndex sourceIndex)

setSourceModel

public void setSourceModel(WAbstractItemModel newSourceModel)

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.

Overrides:

setSourceModel in class WAbstractProxyModel

insertColumns

public boolean insertColumns(int column,
int count,
WModelIndex parent)

Inserts one or more columns.

Inserts count columns at column column in the source model.

Forwards the result indicating success from the source model.

Overrides:

insertColumns in class WAbstractProxyModel

See Also:

WAbstractItemModel.insertRows(int row, int count, WModelIndex parent), WAbstractItemModel.removeColumns(int column, int count, WModelIndex parent), WAbstractItemModel.beginInsertColumns(WModelIndex parent, int first, int last), WAbstractItemModel.endInsertColumns()

insertRows

public boolean insertRows(int row,
int count,
WModelIndex parent)

Inserts one or more rows.

Inserts count rows at row row in the source model.

Forwards the result indicating success from the source model.

Overrides:

insertRows in class WAbstractItemModel

See Also:

WAbstractItemModel.insertColumns(int column, int count, WModelIndex parent), WAbstractItemModel.removeRows(int row, int count, WModelIndex parent), WAbstractItemModel.beginInsertRows(WModelIndex parent, int first, int last), WAbstractItemModel.endInsertRows()

removeColumns

public boolean removeColumns(int column,
int count,
WModelIndex parent)

WAbstractItemModel.removeRows(int row, int count, WModelIndex parent), WAbstractItemModel.insertColumns(int column, int count, WModelIndex parent), WAbstractItemModel.beginRemoveColumns(WModelIndex parent, int first, int last), WAbstractItemModel.endRemoveColumns()

removeRows

public boolean removeRows(int row,
int count,
WModelIndex parent)

Removes rows.

Removes count rows at row row in the source model.

Forwards the result indicating success from the source model.

Overrides:

WAbstractItemModel.removeColumns(int column, int count, WModelIndex parent), WAbstractItemModel.insertRows(int row, int count, WModelIndex parent), WAbstractItemModel.beginRemoveRows(WModelIndex parent, int first, int last), WAbstractItemModel.endRemoveRows()

setHeaderData

public boolean setHeaderData(int section,
Orientation orientation,
java.lang.Object value,
int role)

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.
