Threading and Concurrent Programming Examples

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

Mandelbrot Example	The 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.
Queued Custom Type Example	Demonstrates multi-thread programming using Qt
Semaphores Example	Demonstrates multi-thread programming using Qt
Wait Conditions Example	Demonstrates multi-thread programming using Qt

The 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.

Image Scaling Example	Demonstrates how to asynchronously scale images.
Map Example	Demonstrates how to scale images synchronously.
QtConcurrent Progress Dialog Example	Demonstrates how to monitor the progress of the active processes.
QtConcurrent Word Count Example	Demonstrates how to use the map-reduce algorithm
