from another thread. And only the thread owning a socket instance can use this socket. This implies that you must stop any running timers in the thread that started them and you must call QTcpSocket::close() in the thread owning the socket. Both examples are usually executed in destructors...
A media player, for example, can have a thread for pre-buffering the incoming media, possibly from a harddrive, CD, DVD, or network socket, a thread to process user input, and a thread to play the actual media. A stall in any single thread won't keep the others from doing their job...
Socket accessThe sockets in ZeroMQ are used to manage and enable communication between different parts of a distributed application. As they are thread-safe, so it is recommended to avoid sharing sockets between threads if not necessary. Instead, each thread should work with its own set of ...

While doing Multithreading programming in Java, you would need to have the following concepts very handy − What is thread synchronization? Handling interthread communication Handling thread deadlock Major thread operations Print Page Previous
Asynchronous programming Performance and responsiveness are important factors in the success of your application. Users quickly tire of using even the most functional application if it is unresponsive or regularly appears to freeze when the user initiates an action. Even though it may be a back-end...

It seems to work with every conceivable programming language, operating system, and hardware. This means ØMQ connects entire applications as well as the pieces of applications. It provides a single consistent model for all language APIs. This means that investment in learning ØMQ is rapidly po...
But if the processing-thread uses some resource (file, window, DC, socket, file, and so on), you need to request it to exit gracefully. You can use events to do the same, as explained in the previous article. The attached projects have the complete code. As a last note, you should...
They can be defined withprivate,protectedorpublicvisibility. The method body is referred to as "event scope" of a given Eventbox object. Code in the event scope is based on an event driven programming style where events are signaled by method calls or by callback functions. ...
