事件驱动编程(Event-Driven Programming) 事件驱动的编程侧重于事件。 最终,程序的流程取决于事件。 到目前为止,我们处理顺序或并行执行模型,但具有事件驱动编程概念的模型称为异步模型。 事件驱动的编程取决于始终侦听新传入事件的事件循环。 事件驱动编程的工作取决于事件。 一旦事件循环,然后事件决定执行什么以及以什么...
Event-Driven Programming Event-driven Pages one popular feature of the Web is its interactive nature e.g., you click on buttons to make windows appear e.g., you enter credit card information in a form and submit it pages that respond to user actions such as mouse clicks or form entries ...

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 ...
Event Driven Programming Last Updated 1/04/14 Besides just putting images on the screen, games require that you handle input from the user. You can do that with SDL using the event handling system. //Main loop flagboolquit =false;//Event handlerSDL_Event e; ...

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...
