## Constructor & Destructor Documentation

wxSocketClient::wxSocketClient | ( | wxSocketFlags | flags = `wxSOCKET_NONE` | ) |

Constructor.

Parameters:

  | flags | Socket flags (See wxSocketBase::SetFlags())

virtual wxSocketClient::~wxSocketClient | ( |  | ) | `[virtual]`

Destructor.

Please see wxSocketBase::Destroy().

## Member Function Documentation

virtual bool wxSocketClient::Connect | ( | const wxSockAddress & | address,
|  | bool | wait = `true` |
| ) |  |  | `[virtual]`

Connects to a server using the specified address.

If wait is true, Connect() will wait until the connection completes.

Warning:
  This method will block the GUI.

If wait is false, Connect() will try to establish the connection and return immediately, without blocking the GUI. When used this way, even if Connect() returns false, the connection request can be completed later. To detect this, use WaitOnConnect(), or catch wxSOCKET_CONNECTION events (for successful establishment) and wxSOCKET_LOST events (for connection failure).

Parameters:

  | address | Address of the server.
  | wait | If true, waits for the connection to complete.

Returns:
  true if the connection is established and no error occurs. If wait was true, and Connect() returns false, an error occurred and the connection failed. If wait was false, and Connect() returns false, you should still be prepared to handle the completion of this connection request, either with WaitOnConnect() or by watching wxSOCKET_CONNECTION and wxSOCKET_LOST events.

Reimplemented in wxHTTP.

bool wxSocketClient::Connect | ( | const wxSockAddress & | address,
|  | const wxSockAddress & | local,
|  | bool | wait = `true` |
| ) |  |  |

Connects to a server using the specified address.

If wait is true, Connect() will wait until the connection completes. Warning: This will block the GUI.

If wait is false, Connect() will try to establish the connection and return immediately, without blocking the GUI. When used this way, even if Connect() returns false, the connection request can be completed later. To detect this, use WaitOnConnect(), or catch wxSOCKET_CONNECTION events (for successful establishment) and wxSOCKET_LOST events (for connection failure).

Parameters:

  | address | Address of the server.
  | local | Bind to the specified local address and port before connecting. The local address and port can also be set using SetLocal(), and then using the 2-parameter Connect() method.
  | wait | If true, waits for the connection to complete.

Returns:
  true if the connection is established and no error occurs. If wait was true, and Connect() returns false, an error occurred and the connection failed. If wait was false, and Connect() returns false, you should still be prepared to handle the completion of this connection request, either with WaitOnConnect() or by watching wxSOCKET_CONNECTION and wxSOCKET_LOST events.

  WaitOnConnect(), wxSocketBase::SetNotify(), wxSocketBase::Notify()

bool wxSocketClient::WaitOnConnect | ( | long | seconds = `-1`,
|  | long | milliseconds = `0` |
| ) |  |  |

Wait until a connection request completes, or until the specified timeout elapses.

Use this function after issuing a call to Connect() with wait set to false.

Parameters:

  | seconds | Number of seconds to wait. If -1, it will wait for the default timeout, as set with wxSocketBase::SetTimeout().
  | milliseconds | Number of milliseconds to wait.

Returns:
  WaitOnConnect() returns true if the connection request completes. This does not necessarily mean that the connection was successfully established; it might also happen that the connection was refused by the peer. Use wxSocketBase::IsConnected() to distinguish between these two situations.
  If the timeout elapses, WaitOnConnect() returns false.
  These semantics allow code like this:

                  // Issue the connection request
                  client->Connect(addr, false);

                  // Wait until the request completes or until we decide to give up
                  bool waitmore = true;
                  while ( !client->WaitOnConnect(seconds, millis) && waitmore )
                  {
                      // possibly give some feedback to the user,
                      // and update waitmore as needed.
                  }
                  bool success = client->IsConnected();
