The GdauiDataStore object implements the GtkTreeModel interface on top of a GdaDataModel to be able to display its contents in a GtkTreeView.
GtkTreeModel * gdaui_data_store_new (GdaDataModel *model
);
Creates a GtkTreeModel interface with a GdaDataModel
|
a GdaDataModel object |
Returns : |
the new object. [transfer full] |
Since 4.2
GdaDataProxy * gdaui_data_store_get_proxy (GdauiDataStore *store
);
|
a GdauiDataStore object |
Returns : |
the internal GdaDataProxy being used by store . [transfer none]
|
Since 4.2
gint gdaui_data_store_get_row_from_iter (GdauiDataStore *store
,GtkTreeIter *iter
);
Get the number of the row represented by iter
|
a GdauiDataStore object |
|
a valid GtkTreeIter |
Returns : |
the row number, or -1 if an error occurred |
Since 4.2
gboolean gdaui_data_store_get_iter_from_values (GdauiDataStore *store
,GtkTreeIter *iter
,GSList *values
,gint *cols_index
);
Sets iter
to the first row where all the values in values
at the columns identified at
cols_index
match. If the row can't be identified, then the contents of iter
is not modified.
NOTE: the cols_index
array MUST contain a column index for each value in values
|
a GdauiDataStore object |
|
an unset GtkTreeIter to set to the requested row. [out] |
|
a list of GValue values |
|
an array of gint containing the column number to match each value of values
|
Returns : |
TRUE if the row has been identified iter was set |
Since 4.2
gboolean gdaui_data_store_set_value (GdauiDataStore *store
,GtkTreeIter *iter
,gint col
,const GValue *value
);
Stores a value in the store
data model.
|
a GdauiDataStore object |
|
the considered row |
|
the data model column |
|
the value to store (gets copied) |
Returns : |
TRUE on success |
Since 4.2
void gdaui_data_store_delete (GdauiDataStore *store
,GtkTreeIter *iter
);
Marks the row pointed by iter
to be deleted
|
a GdauiDataStore object |
|
the considered row |
Since 4.2
void gdaui_data_store_undelete (GdauiDataStore *store
,GtkTreeIter *iter
);
Remove the "to be deleted" mark the row pointed by iter
, if it existed.
|
a GdauiDataStore object |
|
the considered row |
Since 4.2
gboolean gdaui_data_store_append (GdauiDataStore *store
,GtkTreeIter *iter
);
Appends a new row.
|
a GdauiDataStore object |
|
an unset GtkTreeIter to set to the appended row |
Returns : |
TRUE if no error occurred |
Since 4.2
