Using synchronous socket operations blocks the -program, which is clearly not acceptable for an event-driven GUI -program. -<p> Once you have opened a non-blocking socket (whether for TCP, UDP, -a UNIX-domain socket, or any other protocol family your operating -system supports), you can create a socket notifier to monitor the -socket. Then you connect the <a href="#activated">activated</a>() signal to the slot you -want to be called when a socket event occurs. -<p> Note for Windows users: the socket passed to TQSocketNotifier will -become non-blocking, even if it was created as a blocking socket. -<p> There are three types of socket notifiers (read, write and -exception); you must specify one of these in the constructor. -<p> The type specifies when the activated() signal is to be emitted: -<ol type=1> -<li> TQSocketNotifier::Read - There is data to be read (socket read event). -<li> TQSocketNotifier::Write - Data can be written (socket write event). -<li> TQSocketNofifier::Exception - An exception has occurred (socket -exception event). We recommend against using this. -</ol> -<p> For example, if you need to monitor both reads and writes for the -same socket you must create two socket notifiers. -<p> For read notifiers it makes little sense to connect the -activated() signal to more than one slot because the data can be -read from the socket only once. -<p> Also observe that if you do not read all the available data when -the read notifier fires, it fires again and again. -<p> For write notifiers, immediately disable the notifier after the -<a href="#activated">activated</a>() signal has been received and you have sent the data to -be written on the socket. When you have more data to be written, -enable it again to get a new activated() signal. The exception is -if the socket data writing operation (send() or equivalent) fails -with a "would block" error, which means that some buffer is full -and you must wait before sending more data. In that case you do -not need to disable and re-enable the write notifier; it will fire -again as soon as the system allows more data to be sent. -<p> The behavior of a write notifier that is left in enabled state -after having emitting the first activated() signal (and no "would -block" error has occurred) is undefined. Depending on the -operating system, it may fire on every pass of the event loop or -not at all. -<p> If you need a time-out for your sockets you can use either <a href="tqobject.html#startTimer">timer events</a> or the <a href="tqtimer.html">TQTimer</a> class. -<p> Socket action is detected in the <a href="ntqapplication.html#exec">main - event loop</a> of TQt. The X11 version of TQt has a single UNIX -select() call that incorporates all socket notifiers and the X -socket. -<p> Note that on XFree86 for OS/2, select() works only in the thread -in which main() is running; you should therefore use that thread -for GUI operations. -<p> <p>See also <a href="ntqsocket.html">TQSocket</a>, <a href="ntqserversocket.html">TQServerSocket</a>, <a href="ntqsocketdevice.html">TQSocketDevice</a>, <a href="ntqfile.html#handle">TQFile::handle</a>(), and <a href="io.html">Input/Output and Networking</a>. - -<hr><h2>Member Type Documentation</h2> -<h3 class=fn><a name="Type-enum"></a>TQSocketNotifier::Type</h3> - -<ul> -<li><tt>TQSocketNotifier::Read</tt> -<li><tt>TQSocketNotifier::Write</tt> -<li><tt>TQSocketNotifier::Exception</tt> -</ul> -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQSocketNotifier"></a>TQSocketNotifier::TQSocketNotifier ( int socket, <a href="ntqsocketnotifier.html#Type-enum">Type</a> type, <a href="tqobject.html">TQObject</a> * parent = 0, const char * name = 0 ) -</h3> -Constructs a socket notifier called <em>name</em>, with the parent, <em>parent</em>.
