Confirmation Dialog Box
Confirmation dialog (sometimes called a warning alert box or chicken box) is a dialog box that asks user to approve requested operation. Usually this dialog appears before a potentially dangerous operation is performed (program termination, file deletion, etc.) Typically confirmation dialog boxes have two buttons (e.g. ''Yes'' / ''No'', ''Confirm'' / ''Cancel'') or three buttons (e. g. ''Save'' / ''Discard'' / ''Cancel''). Some human interface guidelines recommend avoiding unnecessary confirmation dialogs. BlackBerry and Sun Java Java is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea (a part of Pacific Ocean) to the north. With a population of 156.9 million people (including Madura) in mid 2024, proje ... UI guidelines recommended a confirmation button be put before a cancellation button; but a default button should not be associated with a major destructive action.

Alert Dialog Box
An alert dialog box is a special dialog box that is displayed in a graphical user interface when something unexpected occurred that requires immediate user action. The typical alert dialog provides information in a separate box to the user, after which the user can only respond in one way: by closing it. Closing an alert dialog will provide access to the original window, which is not available while the alert dialog is presented. Alert dialogs that block the application are regarded as a bad design solution by usability practitioners, since they are prone to produce mode errors. Also when used as error dialogs, they have been shown to be ineffective in their goals to inform users about an error condition or protect from a destructive operation. Usage Alerts have several typical uses: * Error: informs the user than an operation could not continue or complete due to some insurmountable error. * Warning: alerts that the current course of action could be in some way dangerou ...

Dialog Box
In computing, a dialog box (also simply dialog) is a graphical control element in the form of a small window that communicates information to the user and prompts them for a response. Dialog boxes are classified as " modal" or "modeless", depending on whether they block interaction with the software that initiated the dialog. The type of dialog box displayed is dependent upon the desired user interaction. The simplest type of dialog box is the alert, which displays a message and may require an acknowledgment that the message has been read, usually by clicking "OK", or a decision as to whether or not an action should proceed, by clicking "OK" or "Cancel". Alerts are also used to display a "termination notice"—sometimes requesting confirmation that the notice has been read—in the event of either an intentional closing or unintentional closing (" crash") of an application or the operating system. ( E.g., " Gedit has encountered an error and must close.") Although t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Button (computing)
In computing, a button (sometimes known as a command button or push button) is a Graphical control element (software), graphical control element that provides the user a simple way to trigger an event (computing), event, like searching for a query at a search engine, or to interact with dialog boxes, like confirming an action. Overview A typical button is a rectangle or rounded rectangle, wider than it is tall, with a descriptive caption in its center. Other buttons may be square or round, with simple Icon (computing), icons. The most common method of pressing a button is clicking it with a pointer (user interface), pointer controlled by a mouse (computing), mouse, or a touchpad, but other input such as keystroke can be used to execute the command of a button. However, a button is not always restricted to a rectangular shape. The sole requirement of button interaction is that the user can execute a command by a point-and-click, click action. Thus, pictures and background areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Interface Guidelines
Human interface guidelines (HIG) are software development documents which offer application developers a set of recommendations. Their aim is to improve the experience for the users by making application interfaces more intuitive, learnable, and consistent. Most guides limit themselves to defining a common look and feel for applications in a particular desktop environment. The guides enumerate specific policies. Policies are sometimes based on usability studies of human–computer interaction, but most reflect the platform developers' preferences. The central aim of a HIG is to create a consistent experience across the environment (generally an operating system or desktop environment), including the applications and other tools being used. This means both applying the same visual design and creating consistent access to and behaviour of common elements of the interface – from simple ones such as buttons and icons up to more complex constructions, such as dialog boxes. ...

BlackBerry
BlackBerry is a discontinued brand of handheld devices and related mobile services, originally developed and maintained by the Canadian company Research In Motion (RIM, later known as BlackBerry Limited) until 2016. The first BlackBerry device launched in 1999 in North America, running on the Mobitex network (later also DataTAC) and became very popular because of its "always on" state and ability to send and receive email messages wirelessly. The BlackBerry pioneered push notifications and popularized the practise of " thumb typing" using its QWERTY keyboard, something that would become a trademark feature of the line. In its early years, the BlackBerry proved to be a major advantage over the (typically) one-way communication pagers and it also removed the need for users to tether to personal computers. It became especially used in the corporate world in the US and Canada. RIM debuted the BlackBerry in Europe in September 2001, but it had less appeal there where text mess ...

Java (software Platform)
Java is a set of computer software and specifications that provides a software platform for developing application software and deploying it in a cross-platform computing environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. Java applets, which are less common than standalone Java applications, were commonly run in secure, Sandbox (computer security), sandboxed environments to provide many features of native applications through being embedded in HTML pages. Writing in the Java (programming language), Java programming language is the primary way to produce code that will be deployed as Java byte code, byte code in a Java virtual machine (JVM); byte code compilers are also available for other languages, including Ada (programming language), Ada, JavaScript, Kotlin (programming language), Kotlin (Google's preferred Android language), Python (programming language), Python, and Ruby (p ...

Error-tolerant Design
An error-tolerant design (or human-error-tolerant design) is one that does not unduly penalize user or human errors. It is the human equivalent of fault tolerant design that allows equipment to continue functioning in the presence of hardware faults, such as a "limp-in" mode for an automobile electronics unit that would be employed if something like the oxygen sensor failed. Use of behavior shaping constraints to prevent errors Use of forcing functions or behavior-shaping constraints is one technique in error-tolerant design. An example is the interlock or lockout of reverse in the transmission of a moving car. This prevents errors, and prevention of errors is the most effective technique in error-tolerant design. The practice is known as poka-yoke in Japan where it was introduced by Shigeo Shingo as part of the Toyota Production System. Mitigation of the effects of errors The next most effective technique in error-tolerant design is the mitigation or limitation of the effe ...
