What Is A Graphical User Interface? Definition And Faqs


Graphical User Interface Definition

Users interact with information by manipulating visual widgets, which are designed to respond in accordance with the type of data they hold and support the actions necessary to complete the user’s task. Every technological device that requires user interaction employs a user interface. Common devices the public use on a daily basis include smartphones, computers and tablets, which all feature graphical user interfaces.

  • A good GUI makes an application easy, practical, and efficient to use, and the marketplace success of today’s software programs depends on good GUI design.
  • This article offers a general overview in one area, graphical user interfaces .
  • A GUI allows a computer user to move from application to application .

What Is A Graphical User Interface (gui)?

The end user’s experience should always come first, and the software’s aesthetics should never get in the way of its usability. Rather than get distracted by flashy graphics, choose the interface that makes the most sense for achieving your users’ objectives. Humans are visual creatures, and a good user interface can mean the difference between an application that’s a breakout success and one that lingers in obscurity.

The importance of good user interface design can hardly be understated — GUIs must be easy to understand while also giving users the power to accomplish all the tasks on their plate. When creating an application, many object-oriented tools exist that facilitate writing a graphical user interface. Each GUI element is defined as a class widget from which you can create object instances for your application.

You can code or modify prepackaged methods that an object will use to respond to user stimuli. You either use then as they are defined or extend them into your own classes. Listener methods and application methods are Java methods that you write. Listener methods respond to events by calling application methods. Application methods are ordinary Java methods that perform useful computations. They receive data from the GUI and send data to the GUI to be displayed, but are not usually themselves conderned with the user interface.

window and all objects associated with a task are confined in its window. On the screen, there is a special icon called a cursor whose position defines the current focus of the user, and all input given by the user will be delivered to the window where the cursor is located. The user can select any object he or she wants freely by moving the cursor to the top of the object and clicking a button on the mouse. A double click usually means to invoke a task represented by the clicked icon. Because users can intuitively manipulate objects, GUI is also referred to as direct manipulation user interface .

International Business Machines Corporation PC-compatible computers, that the GUI became the standard interface for personal computers. This in turn led to the development of various graphical interfaces for UNIX and other workstation operating systems. It was even argued that, with the advent of the GUI, engineering had merged with art to create a new medium of the interface. Files, programs, web pages etc. can be represented using a small picture in a graphical user interface. Using an icon is a fast way to open documents, run programs etc. because clicking on them yields instant access. In today’s times, graphical user interfaces are used in many devices such as mobiles, MP3 players, gaming devices, smartphones etc.

Why GUI is better than CLI?

GUIs offer better multitasking and control
Being more user-friendly than a command line (especially for new or novice users), a visual file system is utilized by more people. GUI users have windows that enable a user to view, control, manipulate, and toggle through multiple programs and folders at same time.
