gnome_db_basic_form_new ()

GtkWidget *         gnome_db_basic_form_new             (GdaParameterList *data_set);

Creates a new GnomeDbBasicForm widget using all the parameters provided in paramlist.

The global layout is rendered using a table (a GtkTable), and an entry is created for each node of paramlist.

data_set :

Returns :

the new widget

gnome_db_basic_form_new_custom ()

GtkWidget *         gnome_db_basic_form_new_custom      (GdaParameterList *data_set,
                                                         const gchar *glade_file,

Creates a new GnomeDbBasicForm widget using all the parameters provided in paramlist.

The layout is specified in the glade_file specification, and an entry is created for each node of paramlist.

the name of the top-most widget in glade_file to use in the new form
