invoke_ask_password

Invoke the interaction to ask the user for a password.

It invokes this interaction in the main loop, specifically the MainContext returned by 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 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:

this	a TlsInteraction object
password	a TlsPassword object
cancellable	an optional Cancellable cancellation object

Returns:

The status of the ask password interaction.
