Description: Reference for signal Gio.SocketClient::event

### Signal

# Gio SocketClient::event

since: 2.32

#### Declaration

    void
    event (
      GSocketClient* self,
      GSocketClientEvent event,
      GSocketConnectable* connectable,
      GIOStream* connection,
      gpointer user_data
    )

#### Description [src]

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 up `connectable` in DNS. `connection` will be `NULL`.

- `G_SOCKET_CLIENT_RESOLVED`: `client` has successfully resolved `connectable` 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 `GSocketConnection`, which is not yet connected. Since GLib 2.40, you can access the remote address via g_socket_connection_get_remote_address().

- `G_SOCKET_CLIENT_CONNECTED`: `client` has successfully connected to a remote host. `connection` is the connected `GSocketConnection`.

- `G_SOCKET_CLIENT_PROXY_NEGOTIATING`: `client` is about to negotiate with a proxy to get it to connect to `connectable`. `connection` is the `GSocketConnection` to the proxy server.

- `G_SOCKET_CLIENT_PROXY_NEGOTIATED`: `client` has negotiated a connection to `connectable` through a proxy server. `connection` is the stream returned from g_proxy_connect(), which may or may not be a `GSocketConnection`.

- `G_SOCKET_CLIENT_TLS_HANDSHAKING`: `client` is about to begin a TLS handshake. `connection` is a `GTlsClientConnection`.

- `G_SOCKET_CLIENT_TLS_HANDSHAKED`: `client` has successfully completed the TLS handshake. `connection` is a `GTlsClientConnection`.

- `G_SOCKET_CLIENT_COMPLETE`: `client` has either successfully connected to `connectable` (in which case `connection` is the `GSocketConnection` that it will be returning to the caller) or has failed (in which case `connection` 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 `GSocketClient::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 `GSocketClientEvent` values in the future; unrecognized `event` values should be ignored.

Default handler: The default handler is called after the handlers added via `g_signal_connect()`.
Available since: 2.32
