The Windows wait cursor, informally the Blue circle of death (known as the hourglass cursor until Windows Vista) is a throbber that indicates that an application is busy performing an operation. It can be accompanied by an arrow if the operation is being performed in the background.
The wait cursor can display on programs using the Windows API.
From Windows 1.0 to Windows XP, it was represented by an hourglass. Windows Vista introduced a new, animated wait cursor. The wait cursor in Windows 7 was almost identical. [1] It is possible, however, to change the appearance of the cursor into the original hourglass cursor. Windows 8 introduced a new flat wait cursor. The new cursor is light blue on dark blue and removes the fade and the particles from the animated part.
There are two uses for the wait cursor: short term and long term. The wait cursor is a shared resource in the system across applications and windows. By default, when the mouse cursor is in a window, the cursor shown is controlled by the window's registered window class and handling of WM_SETCURSOR. Different scenarios can be used instead. [2]
In Microsoft Foundation Class Library (MFC) the wait cursor can be controlled by CWaitCursor. If a local instance is created, the wait cursor is reset when the instance goes out of scope. It is used primarily for short term wait cursors. [2]
In Windows Forms, each Control instance has a Cursor property, which can be controlled by the application itself. Control.Cursor is the cursor shown when the mouse is in the control's region; System.Windows.Forms.Cursor.Current is the cursor shown when the mouse enters any window of the application. [2]
For long term wait cursors, the UseWaitCursor property can be set (either Control level or application level) on one occasion and reset at another time. [2]
A scrollbar is an interaction technique or widget in which continuous text, pictures, or any other content can be scrolled in a predetermined direction on a computer display, window, or viewport so that all of the content can be viewed, even if only a fraction of the content can be seen on a device's screen at one time. It offers a solution to the problem of navigation to a known or unknown location within a two-dimensional information space. It was also known as a handle in the very first GUIs. They are present in a wide range of electronic devices including computers, graphing calculators, mobile phones, and portable media players. The user interacts with the scrollbar elements using some method of direct action, the scrollbar translates that action into scrolling commands, and the user receives feedback through a visual updating of both the scrollbar elements and the scrolled content.
In computing, a button is a graphical control element that provides the user a simple way to trigger an event, like searching for a query at a search engine, or to interact with dialog boxes, like confirming an action.
The spinning pinwheel is a type of throbber or variation of the mouse pointer used in Apple's macOS to indicate that an application is busy.
Control Panel is a component of Microsoft Windows that provides the ability to view and change system settings. It consists of a set of applets that include adding or removing hardware and software, controlling user accounts, changing accessibility options, and accessing networking settings. Additional applets are provided by third parties, such as audio and video drivers, VPN tools, input devices, and networking tools.
Extensible Storage Engine (ESE), also known as JET Blue, is an ISAM data storage technology from Microsoft. ESE is the core of Microsoft Exchange Server, Active Directory, and Windows Search. It is also used by a number of Windows components including Windows Update client and Help and Support Center. Its purpose is to allow applications to store and retrieve data via indexed and sequential access.
In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to input.
A throbber, also known as a loading icon, is an animated graphical control element used to show that a computer program is performing an action in the background. In contrast to a progress bar, a throbber does not indicate how much of the action has been completed.
A progress indicator is an element of a command-line interface, a textual user interface, or a graphical user interface that is intended to inform the user that an operation is in progress, to reassure that the system is not hung or waiting for user input, and often to provide the user with an estimate of how far through a task the system has progressed.
The X Window System core protocol is the base protocol of the X Window System, which is a networked windowing system for bitmap displays used to build graphical user interfaces on Unix, Unix-like, and other operating systems. The X Window System is based on a client–server model: a single server controls the input/output hardware, such as the screen, the keyboard, and the mouse; all application programs act as clients, interacting with the user and with the other clients via the server. This interaction is regulated by the X Window System core protocol. Other protocols related to the X Window System exist, both built at the top of the X Window System core protocol or as separate protocols.
Compared with previous versions of Microsoft Windows, features new to Windows Vista are very numerous, covering most aspects of the operating system, including additional management features, new aspects of security and safety, new I/O technologies, new networking features, and new technical features. Windows Vista also removed some others.
The Windows shell is the graphical user interface for the Microsoft Windows operating system. Its readily identifiable elements consist of the desktop, the taskbar, the Start menu, the task switcher and the AutoPlay feature. On some versions of Windows, it also includes Flip 3D and the charms. In Windows 10, the Windows Shell Experience Host interface drives visuals like the Start Menu, Action Center, Taskbar, and Task View/Timeline. However, the Windows shell also implements a shell namespace that enables computer programs running on Windows to access the computer's resources via the hierarchy of shell objects. "Desktop" is the top object of the hierarchy; below it there are a number of files and folders stored on the disk, as well as a number of special folders whose contents are either virtual or dynamically created. Recycle Bin, Libraries, Control Panel, This PC and Network are examples of such shell objects.
Alt+Tab ↹ is the common name for a keyboard shortcut that has been in Microsoft Windows since Windows 2.0 (1987). This shortcut switches between application-level windows without using the mouse; hence it was named Task Switcher.
Windows Speech Recognition (WSR) is speech recognition developed by Microsoft for Windows Vista that enables voice commands to control the desktop user interface, dictate text in electronic documents and email, navigate websites, perform keyboard shortcuts, and operate the mouse cursor. It supports custom macros to perform additional or supplementary tasks.
A mouse button is an electric switch on a computer mouse which can be pressed (“clicked”) to select or interact with an element of a graphical user interface. Mouse buttons are most commonly implemented as miniature snap-action switches.
Windows Search is a content index desktop search platform by Microsoft introduced in Windows Vista as a replacement for both the previous Indexing Service of Windows 2000 and the optional MSN Desktop Search for Windows XP and Windows Server 2003, designed to facilitate local and remote queries for files and non-file items in compatible applications including Windows Explorer. It was developed after the postponement of WinFS and introduced to Windows constituents originally touted as benefits of that platform.
In computing, a hang or freeze occurs when either a process or system ceases to respond to inputs. A typical example is when computer's graphical user interface no longer responds to the user typing on the keyboard or moving the mouse. The term covers a wide range of behaviors in both clients and servers, and is not limited to graphical user interface issues.
Some of the new features included in Windows 7 are advancements in touch, speech and handwriting recognition, support for virtual hard disks, support for additional file formats, improved performance on multi-core processors, improved boot performance, and kernel improvements.
The transition from Windows 7 to Windows 8 introduced a number of new features across various aspects of the operating system. These include a greater focus on optimizing the operating system for touchscreen-based devices and cloud computing.
