Event driven programs key features
Title: unit 14 - event driven programming, author: anthony samrai, name: unit 14 - event driven programming, length: 11 pages, page: 1, published: 2011-12-01 coursework for the btec year 11 group explain the key features of event driven programs. Task 1 in this report i will be talking about the key features of event driven programming, the areas i will be talking about are: service orientated time driven event handlers trigger functions events (mouse, keyboard, user interface) pre-defined functions local variables global. 3 be able to design and implement event driven programs design: event handling using control structures p1 identify the key features of event driven programming m1 describe the features of an event driven language that make it suitable for creating a gui. - 2 - event-driven programming event-driven programming parts of programs wait for messages from an event loop representing system events that have occurred at run-time.
Introduction event driven programming is one of the paradigms within programming the flow in which the program runs is determined by the events which occur within that program. Event driven paradigm has to do with interaction by interaction i mean user inputs for example, when the user presses this button then this happens, if user presses that button then that happens. Video was made for my coursework btec edexel information technology book 1 level 3. Explain the key features of event driven programs p1 key features are listed below an event handler is a computer program known as a function in order to process thee event the event handler must get the information about the event.
Key features of event driven programs service orientated these are programs that have no user interface but can be started and stopped whenever a user requires it alternatively, they can be set to activate at a certain time. P1 - explain the following key features of event driven programs events event handlers event loops/listeners forms triggers events - an event is something that happens outside of the normal flow of a program this mostly happens by the user taking an action of some sort the most. Event loops each and every event driven program needs to have event loops this is usually something a programmer is unaware of event loops are the things which regularly test/check the interface to see whether an event has occurred or not. Service oriented event driven programming can be considered service oriented because it allows the user to define what they want out of the software and receive the expected outcome.
Event driven programs key features
Service oriented provides services that are available on a network, so the code doesn't have to be rewritten every time it is needed, makes it easier to use and saves time. Event-driven program definition is your organization aware of these 6 key public cloud risks the pros and cons of intranets the opposite of event-driven programming would be programming that is written to act regardless of user input.
Event driven programming key features event driven programs typically used for most modern day software applications examples include: word processing, spreadsheets, drawing packages etc usually used for guis where many types of events are generated ie clicking on a button or another object. An event driven program's code does not run from start to finish in order key presses, etc it does not have to be graphical interactions though what is event driven programming imagine that you're building the interface for a photo editor. Developing a program in an event driven language is easy because of the way the programmer only has to deal with event of one control at a time. Key features of procedural programs procedural programming paradigm procedural programming is a paradigm which programmers use to create a structured program key features of event driven programs event driven operating systems.
Unit 14 - p1 - event driven programming event driven programs key features event driven programming is a programming in which the control flow of the programme is determined through events such as: mouse clicks, key presses and timers. Event driven program event-driven programming is a flow of programs which are determined by events like user actions for example mouse clicks, sensor outputs, or messages from other programs there are a lot of key features that are used in event driven program without these feature then. Slide 3 - key features event handlers trigger functions events event loops forms flexibility service oriented suitability for guis simplicity of programming time driven. Features object-oriented programming uses objects based on a small number of key ideas from software engineering and computer science oop toolkits also enhanced the popularity of event-driven programming. This is a written report on the features of event driven programming it will include everything from examples of an event driven program, simple architecture of how an event driven program operates.
