struct GdaDataModelPrivate
struct GdaDataModelPrivate; |
gda_data_model_changed ()
void gda_data_model_changed (GdaDataModel *model); |
Notify 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.
gda_data_model_freeze ()
void gda_data_model_freeze (GdaDataModel *model); |
Disable notifications of changes on the given data model. To
re-enable notifications again, you should call the
gda_data_model_thaw function.
gda_data_model_thaw ()
void gda_data_model_thaw (GdaDataModel *model); |
Re-enable notifications of changes on the given data model.
gda_data_model_get_n_rows ()
gint gda_data_model_get_n_rows (GdaDataModel *model); |
Return the number of rows in the given data model.
gda_data_model_get_n_columns ()
gint gda_data_model_get_n_columns (GdaDataModel *model); |
Return the number of columns in the given data model.
gda_data_model_describe_column ()
Query 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.
gda_data_model_get_column_title ()
const gchar* gda_data_model_get_column_title
(GdaDataModel *model,
gint col); |
Return the title for the given column in a data model object.
gda_data_model_set_column_title ()
void gda_data_model_set_column_title (GdaDataModel *model,
gint col,
const gchar *title); |
gda_data_model_get_column_position ()
gint gda_data_model_get_column_position
(GdaDataModel *model,
const gchar *title); |
Get the position of a column on the data model, based on
the column's title.
gda_data_model_get_row ()
const GdaRow* gda_data_model_get_row (GdaDataModel *model,
gint row); |
Retrieve a given row from a data model.
gda_data_model_get_value_at ()
const GdaValue* gda_data_model_get_value_at (GdaDataModel *model,
gint col,
gint row); |
Retrieve 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.
gda_data_model_is_editable ()
gboolean gda_data_model_is_editable (GdaDataModel *model); |
Check whether the given data model can be edited or not.
gda_data_model_append_row ()
const GdaRow* gda_data_model_append_row (GdaDataModel *model,
const GList *values); |
Append a row to the given data model.
gda_data_model_remove_row ()
gboolean gda_data_model_remove_row (GdaDataModel *model,
const GdaRow *row); |
Remove a row from the data model. This results in the underlying
database row being removed in the database.
gda_data_model_update_row ()
gboolean gda_data_model_update_row (GdaDataModel *model,
const GdaRow *row); |
Update a row data model. This results in the underlying
database row's values being changed.
GdaDataModelForeachFunc ()
gboolean (*GdaDataModelForeachFunc) (GdaDataModel *model,
GdaRow *row,
gpointer user_data); |
gda_data_model_foreach ()
Call 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.
The callback function must have the following form:
gboolean foreach_func (GdaDataModel *model, GdaRow *row, gpointer user_data)
where "row" would be the row being read, and "user_data" the parameter
specified in user_data in the call to gda_data_model_foreach.
This callback function can return FALSE to stop the processing. If it
gda_data_model_is_editing ()
gboolean gda_data_model_is_editing (GdaDataModel *model); |
Check whether this data model is in editing mode or not. Editing
mode is set to TRUE when gda_data_model_begin_edit has been
called successfully, and is not set back to FALSE until either
gda_data_model_cancel_edit or gda_data_model_end_edit have
been called.
gda_data_model_begin_edit ()
gboolean gda_data_model_begin_edit (GdaDataModel *model); |
Start edition of this data model. This function should be the
first called when modifying the data model.
gda_data_model_cancel_edit ()
gboolean gda_data_model_cancel_edit (GdaDataModel *model); |
Cancels edition of this data model. This means that all changes
will be discarded, and the old data put back in the model.
gda_data_model_end_edit ()
gboolean gda_data_model_end_edit (GdaDataModel *model); |
Approves all modifications and send them to the underlying
data source/store.
gda_data_model_to_comma_separated ()
gchar* gda_data_model_to_comma_separated
(GdaDataModel *model); |
Convert the given model into a comma-separated series of rows.
gda_data_model_to_tab_separated ()
gchar* gda_data_model_to_tab_separated (GdaDataModel *model); |
gda_data_model_to_xml ()
gchar* gda_data_model_to_xml (GdaDataModel *model,
gboolean standalone); |
gda_data_model_to_xml_node ()
xmlNodePtr gda_data_model_to_xml_node (GdaDataModel *model,
const gchar *name); |
gda_data_model_get_command_text ()
const gchar* gda_data_model_get_command_text
(GdaDataModel *recset); |
Get the text of command that generated this data model.
gda_data_model_set_command_text ()
void gda_data_model_set_command_text (GdaDataModel *recset,
const gchar *txt); |
gda_data_model_get_command_type ()
GdaCommandType gda_data_model_get_command_type
(GdaDataModel *recset); |
Get the type of command that generated this data model.
gda_data_model_set_command_type ()
void gda_data_model_set_command_type (GdaDataModel *recset,
GdaCommandType type); |
