## Functions

### gdaui_login_new ()

    GtkWidget *
    gdaui_login_new (const gchar *dsn);

Creates a new login widget which enables the user to specify connection parameters.

a new widget.

### gdaui_login_set_mode ()

    void
    gdaui_login_set_mode (GdauiLogin *login,
                          GdauiLoginMode mode);

Set how `login` operates

### gdaui_login_get_connection_information ()

    const GdaDsnInfo *
    gdaui_login_get_connection_information
                                   (GdauiLogin *login);

Get the information specified in `login` as a pointer to a (read-only) GdaDsnInfo. If the connection is not specified by a DSN, then the 'name' attribute of the returned GdaDsnInfo will be `NULL`, and otherwise it will contain the name of the selected DSN.

#### Parameters

login | a GdauiLogin object |

### gdaui_login_set_dsn ()

    void
    gdaui_login_set_dsn (GdauiLogin *login,
                         const gchar *dsn);

Changes the information displayed in `login` , to represent `dsn` . If `login` 's mode has `GDA_UI_LOGIN_HIDE_DSN_SELECTION_MODE`, then the DSN information is extracted and displayed in the direct login area.

If `dsn` is not a declared data source name, then a warning is shown and the result is the same as having passed `NULL` for the `dsn` argument.

In any case `login` 's mode (set by `gdaui_login_set_mode()`) is not changed.

#### Parameters

login | a GdauiLogin object |
dsn | a data source name, or `NULL`. | [allow-none]

### gdaui_login_set_connection_information ()

    void
    gdaui_login_set_connection_information

                                    const GdaDsnInfo *cinfo);

Changes the information displayed in `login` , to represent `cinfo` . If `login` 's mode has `GDA_UI_LOGIN_HIDE_DIRECT_CONNECTION_MODE`, then if `cinfo->name` is not `NULL` it is displayed in the DSN selector, otherwise a warning is shown and the result is the same as having passed `NULL` for the `cinfo` argument.

In any case `login` 's mode (set by `gdaui_login_set_mode()`) is not changed.

#### Parameters

login | a GdauiLogin object |
cinfo | a pointer to a structure representing the information to display. |
