event
Description:
public virtual signal void event (SocketClientEvent event, SocketConnectable connectable, IOStream? connection)
Emitted when client
's activity on connectable
changes state.
Among other things, this can be used to provide progress information about a network connection in the UI. The meanings of the different
event
values are as follows:
- g_socket_client_resolving:
client
is about to look upconnectable
in DNS.connection
will be null. - g_socket_client_resolved:
client
has successfully resolvedconnectable
in DNS.connection
will be null. - g_socket_client_connecting:
client
is about to make a connection to a remote host; either a proxy server or the destination server itself.connection
is the SocketConnection, which is not yet connected. Since GLib 2.40, you can access the remote address via get_remote_address. - g_socket_client_connected:
client
has successfully connected to a remote host.connection
is the connected SocketConnection. - g_socket_client_proxy_negotiating:
client
is about to negotiate with a proxy to get it to connect toconnectable
.connection
is the SocketConnection to the proxy server. - g_socket_client_proxy_negotiated:
client
has negotiated a connection toconnectable
through a proxy server.connection
is the stream returned from connect, which may or may not be a SocketConnection. - g_socket_client_tls_handshaking:
client
is about to begin a TLS handshake.connection
is a TlsClientConnection. - g_socket_client_tls_handshaked:
client
has successfully completed the TLS handshake.connection
is a TlsClientConnection. - g_socket_client_complete:
client
has either successfully connected toconnectable
(in which caseconnection
is the SocketConnection that it will be returning to the caller) or has failed (in which caseconnection
is null and the client is about to return an error).
Each event except g_socket_client_complete may be emitted multiple times (or not at all) for a given
connectable (in particular, if client
ends up attempting to connect to more than one address). However, if client
emits the event signal at all for a given connectable, then it will always emit it with
g_socket_client_complete when it is done.
Note that there may be additional SocketClientEvent values in the future;
unrecognized event
values should be ignored.
Parameters:
event |
the event that is occurring |
connectable |

connection |
