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 download and 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.
-
Run Function Example: Demonstrates how to run standard functions concurrently.
