## Functions

### e_dbus_authenticator_get_without_password ()

    gboolean
    e_dbus_authenticator_get_without_password
                                   (EDBusAuthenticator *object);

Gets the value of the "WithoutPassword" D-Bus property.

Since this D-Bus property is both readable and writable, it is meaningful to use this function on both the client- and service-side.

#### Parameters

object | A EDBusAuthenticator. |

#### Returns

The property value.

### e_dbus_authenticator_set_without_password ()

                                    gboolean value);

Sets the "WithoutPassword" D-Bus property to `value` .

Since this D-Bus property is both readable and writable, it is meaningful to use this function on both the client- and service-side.

#### Parameters

object | A EDBusAuthenticator. |
value | The value to set. |

### e_dbus_authenticator_proxy_new_for_bus ()

    void
    e_dbus_authenticator_proxy_new_for_bus
                                   (GBusType bus_type,
                                    GDBusProxyFlags flags,

                                    gpointer user_data);

Like `e_dbus_authenticator_proxy_new()` but takes a GBusType instead of a GDBusConnection.

When the operation is finished, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from. You can then call `e_dbus_authenticator_proxy_new_for_bus_finish()` to get the result of the operation.

See `e_dbus_authenticator_proxy_new_for_bus_sync()` for the synchronous, blocking version of this constructor.

#### Parameters

bus_type | A GBusType. |
flags | Flags from the GDBusProxyFlags enumeration. |
name | A bus name (well-known or unique). |
object_path | An object path. |
cancellable | A GCancellable or `NULL`. | [allow-none]
callback | A GAsyncReadyCallback to call when the request is satisfied. |
user_data | User data to pass to `callback` . |

[transfer full][type EDBusAuthenticatorSkeleton]

## Types and Values

### EDBusAuthenticator

    typedef struct _EDBusAuthenticator EDBusAuthenticator;

Abstract interface type for the D-Bus interface org.gnome.evolution.dataserver.Authenticator.

### struct EDBusAuthenticatorProxy

    struct EDBusAuthenticatorProxy;

The EDBusAuthenticatorProxy structure contains only private data and should only be accessed using the provided API.

### struct EDBusAuthenticatorSkeleton

    struct EDBusAuthenticatorSkeleton;

The EDBusAuthenticatorSkeleton structure contains only private data and should only be accessed using the provided API.

## Property Details

### The `“without-password”` property

      “without-password”         gboolean

Represents the D-Bus property "WithoutPassword".

Since the D-Bus property for this GObject property is both readable and writable, it is meaningful to both read from it and write to it on both the service- and client-side.

Flags: Read / Write

Default value: FALSE

## Signal Details

### The `“authenticate”` signal

    void
    user_function (EDBusAuthenticator *object,
                   gchar              *arg_encrypted_secret,
                   gpointer            user_data)

On the client-side, this signal is emitted whenever the D-Bus signal "Authenticate" is received.

On the service-side, this signal can be used with e.g. `g_signal_emit_by_name()` to make the object emit the D-Bus signal.

#### Parameters

object | A EDBusAuthenticator. |
arg_encrypted_secret | Argument. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

### The `“dismissed”` signal

    void
    user_function (EDBusAuthenticator *object,
                   gpointer            user_data)

On the client-side, this signal is emitted whenever the D-Bus signal "Dismissed" is received.

On the service-side, this signal can be used with e.g. `g_signal_emit_by_name()` to make the object emit the D-Bus signal.

#### Parameters

object | A EDBusAuthenticator. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

### The `“handle-accepted”` signal

    gboolean
    user_function (EDBusAuthenticator    *object,
                   GDBusMethodInvocation *invocation,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Accepted()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `e_dbus_authenticator_complete_accepted()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A EDBusAuthenticator. |
invocation | A GDBusMethodInvocation. |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

Flags: Run Last

### The `“handle-cancel”` signal

    gboolean
    user_function (EDBusAuthenticator    *object,
                   GDBusMethodInvocation *invocation,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Cancel()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `e_dbus_authenticator_complete_cancel()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A EDBusAuthenticator. |
invocation | A GDBusMethodInvocation. |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

Flags: Run Last

### The `“handle-ready”` signal

    gboolean
    user_function (EDBusAuthenticator    *object,
                   GDBusMethodInvocation *invocation,
                   gchar                 *arg_encryption_key,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Ready()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `e_dbus_authenticator_complete_ready()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A EDBusAuthenticator. |
invocation | A GDBusMethodInvocation. |
arg_encryption_key | Argument passed by remote caller. |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

Flags: Run Last

### The `“handle-rejected”` signal

    gboolean
    user_function (EDBusAuthenticator    *object,
                   GDBusMethodInvocation *invocation,
                   gpointer               user_data)

Signal emitted when a remote caller is invoking the `Rejected()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `e_dbus_authenticator_complete_rejected()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

#### Parameters

object | A EDBusAuthenticator. |
invocation | A GDBusMethodInvocation. |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.

Flags: Run Last

### The `“server-error”` signal

    void
    user_function (EDBusAuthenticator *object,
                   gchar              *arg_name,
                   gchar              *arg_message,
                   gpointer            user_data)

On the client-side, this signal is emitted whenever the D-Bus signal "ServerError" is received.

On the service-side, this signal can be used with e.g. `g_signal_emit_by_name()` to make the object emit the D-Bus signal.

#### Parameters

object | A EDBusAuthenticator. |
arg_name | Argument. |
arg_message | Argument. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last
