Description
GTlsInteraction 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 GTlsInteraction with a TLS connection use
g_tls_connection_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
g_tls_interaction_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 in their class
initialization function. Any interactions not implemented will return
G_TLS_INTERACTION_UNHANDLED
. If a derived class implements an async method,
it must also implement the corresponding finish method.
Functions
g_tls_interaction_invoke_ask_password ()
GTlsInteractionResult g_tls_interaction_invoke_ask_password (GTlsInteraction *interaction
,GTlsPassword *password
,GCancellable *cancellable
,GError **error
);
Invoke the interaction to ask the user for a password. It invokes this
interaction in the main loop, specifically the GMainContext returned by
g_main_context_get_thread_default()
when the interaction is created. This
is called by called by GTlsConnection or GTlsDatabase 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 G_TLS_INTERACTION_FAILED
will be returned with an error that
contains a G_IO_ERROR_CANCELLED
error code. Certain implementations may
not support immediate cancellation.
Parameters
interaction |
a GTlsInteraction object |
|
password |
a GTlsPassword object |
|
cancellable |
an optional GCancellable cancellation object |
|
error |
an optional location to place an error on failure |

g_tls_interaction_invoke_request_certificate ()
GTlsInteractionResult g_tls_interaction_invoke_request_certificate (GTlsInteraction *interaction
,GTlsConnection *connection
,GTlsCertificateRequestFlags flags
,GCancellable *cancellable
,GError **error
);
Invoke the interaction to ask the user to choose a certificate to
use with the connection. It invokes this interaction in the main
loop, specifically the GMainContext returned by
g_main_context_get_thread_default()
when the interaction is
created. This is called by called by GTlsConnection when the peer
requests a certificate during the handshake.
Derived subclasses usually implement a certificate selector, although they may also choose to provide a certificate from elsewhere. Alternatively the user may abort this certificate request, which may or may not 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 G_TLS_INTERACTION_FAILED
will be returned with an error that
contains a G_IO_ERROR_CANCELLED
error code. Certain implementations may
not support immediate cancellation.

g_tls_interaction_ask_password_finish ()
GTlsInteractionResult g_tls_interaction_ask_password_finish (GTlsInteraction *interaction
,GAsyncResult *result
,GError **error
);
Complete an ask password user interaction request. This should be once
the g_tls_interaction_ask_password_async()
completion callback is called.
If G_TLS_INTERACTION_HANDLED
is returned, then the GTlsPassword 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 G_TLS_INTERACTION_FAILED

);
Run synchronous interaction to ask the user to choose a certificate to use
with the connection. In general, g_tls_interaction_invoke_request_certificate()
should be used instead of this function.
Derived subclasses usually implement a certificate selector, although they may also choose to provide a certificate from elsewhere. Alternatively the user may abort this certificate request, which will usually abort the TLS connection.

The class for GTlsInteraction. Derived classes implement the various virtual interaction methods to handle TLS interactions.
Derived classes can choose to implement whichever interactions methods they'd like to support by overriding those virtual methods in their class initialization function. If a derived class implements an async method, it must also implement the corresponding finish method.
The synchronous interaction methods should implement to display modal dialogs, and the asynchronous methods to display modeless dialogs.
If the user cancels an interaction, then the result should be
G_TLS_INTERACTION_FAILED
and the error should be set with a domain of
G_IO_ERROR
and code of G_IO_ERROR_CANCELLED
.
