## Detailed Description

TlsInteraction - Interaction with the user during TLS operations.

TlsInteraction provides a mechanism for the TLS connection and database code to interact with the user. It can be used to ask the user for passwords.

To use a TlsInteraction with a TLS connection use Gio::TlsConnection::set_interaction().

Callers should instantiate a derived class that implements the various interaction methods to show the required dialogs.

Callers should use the 'invoke' functions like invoke_ask_password() to run interaction methods. These functions make sure that the interaction is invoked in the main loop and not in the current thread, if the current thread is not running the main loop.

Derived classes can choose to implement whichever interactions methods they'd like to support by overriding those virtual methods. Any interactions not implemented will return Gio::TLS_INTERACTION_UNHANDLED. If a derived class implements an async method, it must also implement the corresponding finish method.

Since glibmm 2.36:

## Member Function Documentation

TlsInteractionResult Gio::TlsInteraction::ask_password | ( | const Glib::RefPtr< TlsPassword >& | password,
|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |

Run synchronous interaction to ask the user for a password.

In general, g_tls_interaction_invoke_ask_password() should be used instead of this function.

Derived subclasses usually implement a password prompt, although they may also choose to provide a password from elsewhere. The password value will be filled in and then callback will be called. Alternatively the user may abort this password request, which will usually abort the TLS connection.

If the interaction is cancelled by the cancellation object, or by the user then TLS_INTERACTION_FAILED will be returned with an error that contains a IO_ERROR_CANCELLED error code. Certain implementations may not support immediate cancellation.

Since glibmm 2.30:

Parameters

  password | A TlsPassword object.
  cancellable | An optional Cancellable cancellation object.

Returns
  The status of the ask password interaction.

TlsInteractionResult Gio::TlsInteraction::ask_password | ( | const Glib::RefPtr< TlsPassword >& | password | ) |

A ask_password() convenience overload.

void Gio::TlsInteraction::ask_password_async | ( | const Glib::RefPtr< TlsPassword >& | password,
|  | const SlotAsyncReady& | slot,
|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |

Run asynchronous interaction to ask the user for a password.

In general, g_tls_interaction_invoke_ask_password() should be used instead of this function.

Derived subclasses usually implement a password prompt, although they may also choose to provide a password from elsewhere. The password value will be filled in and then slot will be called. Alternatively the user may abort this password request, which will usually abort the TLS connection.

If the interaction is cancelled by the cancellation object, or by the user then TLS_INTERACTION_FAILED will be returned with an error that contains a IO_ERROR_CANCELLED error code. Certain implementations may not support immediate cancellation.

Certain implementations may not support immediate cancellation.

Since glibmm 2.30:

Parameters

  password | A TlsPassword object.
  cancellable | An optional Cancellable cancellation object.
  slot | Will be called when the interaction completes.

void Gio::TlsInteraction::ask_password_async | ( | const Glib::RefPtr< TlsPassword >& | password,
|  | const SlotAsyncReady& | slot
| ) |  |

A ask_password_async() convenience overload.

void Gio::TlsInteraction::ask_password_async | ( | const Glib::RefPtr< TlsPassword >& | password,
|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |

virtual void Gio::TlsInteraction::ask_password_async_vfunc | ( | const Glib::RefPtr< TlsPassword >& | password,

|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |
| virtual

TlsInteractionResult Gio::TlsInteraction::ask_password_finish | ( | const Glib::RefPtr< AsyncResult >& | result | ) |

Complete an ask password user interaction request.

This should be once the g_tls_interaction_ask_password_async() completion callback is called.

If TLS_INTERACTION_HANDLED is returned, then the TlsPassword passed to g_tls_interaction_ask_password() will have its password filled in.

If the interaction is cancelled by the cancellation object, or by the user then TLS_INTERACTION_FAILED will be returned with an error that contains a IO_ERROR_CANCELLED error code.

Since glibmm 2.30:

Parameters

  result | The result passed to the callback.

Returns
  The status of the ask password interaction.

GTlsInteraction* Gio::TlsInteraction::gobj_copy | ( |  | ) |

TlsInteractionResult Gio::TlsInteraction::invoke_ask_password | ( | const Glib::RefPtr< TlsPassword >& | password,
|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |

Invoke the interaction to ask the user for a password.

It invokes this interaction in the main loop, specifically the MainContext returned by Glib::main_context_get_thread_default() when the interaction is created. This is called by called by TlsConnection or TlsDatabase to ask the user for a password.

Derived subclasses usually implement a password prompt, although they may also choose to provide a password from elsewhere. The password value will be filled in and then callback will be called. Alternatively the user may abort this password request, which will usually abort the TLS connection.

The implementation can either be a synchronous (eg: modal dialog) or an asynchronous one (eg: modeless dialog). This function will take care of calling which ever one correctly.

If the interaction is cancelled by the cancellation object, or by the user then TLS_INTERACTION_FAILED will be returned with an error that contains a IO_ERROR_CANCELLED error code. Certain implementations may not support immediate cancellation.

Since glibmm 2.30:

Parameters

  password | A TlsPassword object.
  cancellable | An optional Cancellable cancellation object.

Returns
  The status of the ask password interaction.

TlsInteractionResult Gio::TlsInteraction::invoke_ask_password | ( | const Glib::RefPtr< TlsPassword >& | password | ) |
