inputeventcodes

InputEventCodes is a system used in various operating systems and software to represent different types of input events. These events can originate from a variety of sources, including keyboards, mice, touchscreens, game controllers, and other input devices. Each distinct action or state change from an input device is assigned a unique numerical code.

These codes are fundamental to how applications process user interactions. When a user presses a key on a keyboard, for instance, the operating system generates an input event with a specific code corresponding to that key. Similarly, moving a mouse, clicking a button, or touching a screen all result in distinct input event codes.

The primary purpose of InputEventCodes is to provide a standardized and abstract way for software to receive and interpret user input. Instead of dealing with the low-level details of specific hardware, applications can listen for these general event codes. This abstraction allows developers to create software that is compatible with a wide range of input devices without needing to write custom code for each one.

Different operating systems and frameworks may implement their own specific sets of input event codes, though there are often commonalities for widely used devices like keyboards and mice. Understanding these codes is particularly important for game development, accessibility features, and low-level system programming where precise control over user input is required.
