The third step in developing an event-driven program is to write themain loop. This is a function that checks for the occurrence of events, and then calls the matching event handler to process it. Most event-driven programming environments already provide this main loop, so it need not be ...

At the top of our main loop we have our event loop. What this does is keep processing the event queue until it is empty. When you press a key, move the mouse, or touch a touch screen you put events onto the event queue. The event queue will then store them in the order the even...
First, let’s establish a definition for event-driven development. This is a programming paradigm where the flow of execution is determined by events triggered by actions (such user interaction, messaging from other threads, etc). In this sense, Android is partially event-driven: we ...
An Introduction to Programming Using Alice Boolean Logic Boolean logic is a form of mathematics in which the only values used are true and false. Boolean logic is the basis of all modern computing. There are three basic operations in Boolean logic – AND, OR, and ...
The control resides in the event-driven infrastructure, so from the application standpoint the control isinvertedcompared to sequential programs, such as threads in a traditional RTOS. This is the key characteristic of all event-driven systems and is the essence of event-driven programming. The inv...
