changed

void changed()

Notifies listeners of the given data model object of changes in the underlying data. Listeners usually will connect themselves to the "changed" signal in the GdaDataModel class, thus being notified of any new data being appended or removed from the data model.

rowInserted

void rowInserted(int row)

Emits the 'row_inserted' and 'changed' signals on model.

rowUpdated

void rowUpdated(int row)

Emits the 'row_updated' and 'changed' signals on model.

rowRemoved

void rowRemoved(int row)

Emits the 'row_removed' and 'changed' signal on model.

columnInserted

void columnInserted(int col)

Emits the 'column_inserted' and 'changed' signals on model.

columnUpdated

void columnUpdated(int col)

Emits the 'column_updated' and 'changed' signals on model.

columnRemoved

void columnRemoved(int col)

Emits the 'column_removed' and 'changed' signal on model.

freeze

void freeze()

Disables notifications of changes on the given data model. To re-enable notifications again, you should call the gda_data_model_thaw function.

thaw

void thaw()

Re-enables notifications of changes on the given data model.

getNRows

int getNRows()

getNColumns

int getNColumns()

describeColumn

FieldAttributes describeColumn(int col)

Queries the underlying data model implementation for a description of a given column. That description is returned in the form of a GdaFieldAttributes structure, which contains all the information about the given column in the data model.

getColumnTitle

string getColumnTitle(int col)

setColumnTitle

void setColumnTitle(int col, string title)

Sets the title of the given col in model.

getColumnPosition

int getColumnPosition(string title)

Gets the position of a column on the data model, based on the column's title.

getRow

Row getRow(int row)

Retrieves a given row from a data model.

getValueAt

Value getValueAt(int col, int row)

Retrieves the data stored in the given position (identified by the col and row parameters) on a data model. This is the main function for accessing data in a model.

isUpdatable

int isUpdatable()

Checks whether the given data model can be updated or not.

appendRow

Row appendRow(ListG values)

Appends a row to the given data model.

removeRow

int removeRow(Row row)

Removes a row from the data model. This results in the underlying database row being removed in the database.

updateRow

int updateRow(Row row)

Updates a row data model. This results in the underlying database row's values being changed.

appendColumn

int appendColumn(FieldAttributes attrs)

Appends a column to the given data model. If successful, the position of the new column in the data model is set on col, and you can grab it using gda_field_attributes_get_position.

updateColumn

int updateColumn(int col, FieldAttributes attrs)

Updates a column in the given data model. This results in the underlying database row's values being changed.

removeColumn

int removeColumn(int col)

Removes a column from the data model. This means that all values attached to this column in the data model will be destroyed in the underlying database.

foreac

void foreac(GdaDataModelForeachFunc func, void* userData)

Calls the specified callback function for each row in the data model. This will just traverse all rows, and call the given callback function for each of them.

hasChanged

int hasChanged()

Checks whether this data model is in updating mode or not. Updating mode is set to TRUE when gda_data_model_begin_update has been called successfully, and is not set back to FALSE until either gda_data_model_cancel_update or gda_data_model_end_update have been called.

beginUpdate

int beginUpdate()

Starts update of this data model. This function should be the first called when modifying the data model.

cancelUpdate

int cancelUpdate()

Cancels update of this data model. This means that all changes will be discarded, and the old data put back in the model.

endUpdate

int endUpdate()

Approves all modifications and send them to the underlying data source/store.

toCommaSeparated

string toCommaSeparated()

Converts the given model into a comma-separated series of rows.

toTabSeparated

string toTabSeparated()

Converts the given model into a tab-separated series of rows.

toXml

string toXml(int standalone)

Converts the given model into a XML representation.

toXmlNode

xmlNodePtr toXmlNode(string name)

Converts a GdaDataModel into a xmlNodePtr (as used in libxml).

addDataFromXmlNode

int addDataFromXmlNode(xmlNodePtr node)

Adds the data from a XML node to the given data model.

getCommandText

string getCommandText()

Gets the text of command that generated this data model.

setCommandText

void setCommandText(string txt)

Sets the command text of the given model.

getCommandType

GdaCommandType getCommandType()

Gets the type of command that generated this data model.

setCommandType

void setCommandType(GdaCommandType type)

Sets the type of command that generated this data model.
