线程和并发编程范例

Qt makes it easy to write multithreaded applications. Signals and slots can be used to safely communicate between threads in your application.

Mandelbrot 范例 Mandelbrot example demonstrates multi-thread programming using Qt. It shows how to use a worker thread to perform heavy computations without blocking the main thread's event loop
队列自定义类型范例 Demonstrates multi-thread programming using Qt
信号量范例 Demonstrates multi-thread programming using Qt
等待条件范例 Demonstrates multi-thread programming using Qt

QtConcurrent namespace includes a collection of classes and functions for straightforward concurrent programming.

These examples show how to apply the basic techniques of concurrent programming to simple problems.
