Detailed Description

Task dispatcher.

Use TaskDispatcher to schedule execution of callbacks to the Kanzi UI thread. You can access a Kanzi UI object only on the same thread where you create object. You can wrap code that accesses UI objects with tasks and submit them to the TaskDispatcher from any thread. The UI thread executes these tasks during its main loop.
