Thread is surely one of the most discussed topic on Qt forums. Meanwhile, I never managed to find a simple example which describes how to simply do what I want to do: run a thread to do things and interrupt it if necessary (for example if the GUI is closed). That's why I'm writing this… Qt Thread | Kernelcoder's Blog Posts about Qt Thread written by KernelCoder. How to Use? Just inherit QThread class and override run method.Now while you call start slot through an instance of the inherited class, then while your overrided run get execution, another thread of control is begin with the starting point as run method.That is, run method execution life cycle (scope) run on another thread.

Whether it are Win32, POSIX or other threads, they all basically work the same… QThreads general usage - Qt Wiki The main thing in this example to keep in mind when using a QThread is that it's not a thread. It's a wrapper around a thread object. This wrapper provides the signals, slots and methods to easily use the thread object within a Qt project. To use it, prepare a QObject subclass with all your desired functionality in it. Qt thread: simple, complete and stable (with full sources ...

If the receiver is in the same thread, the event will be processed later, as the event loop iterates. The event will be deleted right after being processed in the thread that processes it. An event posted using a QueuedConnection is a QMetaCallEvent. When processed, that event will call the slot the same way we call them for direct connections. Communicating with the Main Thread - InformIT Communicating with the Main Thread. When a Qt application starts, only one thread is running—the main thread. This is the only thread that is allowed to create the QApplication or QCoreApplication object and call exec() on it. After the call to exec(), this thread is either waiting for an event or processing an event. Threads Events QObjects - Qt Wiki

Qt Signals & Slots: How they work | nidomiro The Qt:: QueuedConnection will ensure that the Slot is called in the thread of the corresponding QObject. It uses the fact, that every thread in Qt ( QThread) has a Event-queue by default. So if you call the Signal of the QObject the method generated by Qt will enqueue the command to call the Slot in the Event-queue of the other QObjects thread ... Qt - Calling one form from another form - Experts Exchange i am sorry if i have bruised your ego. i am grateful to you for solving my current problem. however, this solution is only temporary, coz if i increase the number of widgets and calling forms, it results in segmentation fault. secondly, there is a way out, where NO CODE WRITING is required to call another form. i am working on both of these.
