wxSocketClient::wxSocketClient | ( | wxSocketFlags | flags = wxSOCKET_NONE | ) |
Constructor.
Notice that if the object is created from a worker thread or if it is created from the main thread but the event loop is not running, flags parameter must include wxSOCKET_BLOCK as non-blocking sockets require dispatching events, which can only be done in the main thread.
flags | Socket flags (See wxSocketBase::SetFlags()) |
|
virtual |
Destructor.
Please see wxSocketBase::Destroy().

virtual |
Connects to a server using the specified address.
If wait is true, Connect() will wait until the connection completes.
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).
address | Address of the server. |
wait | If true, waits for the connection to complete. |
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).
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. |
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.
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. |
