| Caret | A special blinking indicator for text input (see MEditBox). |
| Collection classes | 8 classes that store data in various forms. Also called "data structures". See Collections and iterators for more information. |
| Complexity | A measure of algorithmic performance. |
| Container | A type of window whose primary task is to contain other windows for a more structured app design (see window classes). |
| Cursor | Analog (or pseudo-analog) input device. |
| DEBUG mode | A special compiler mode, which generates an app with various safety checks inside. |
| Digger | A special kind of MWindow revealer, essential for message processing. |
| Drawing functions | See Painting functions. |
| Drawing transformation | The rationale for using drawing transformations: MTransform and MWindow::setDrawTransform. |
| Embedded | Child window with z<0, which is embedded within its parent. |
| Error reporting | Elgrint supports three mechanisms for reporting errors: exceptions, error flags, and assertion macros. |
| Exit code | A "return value" of the app itself. |
| External message | Same as System message. See Messages. |
| Floating | Child window with z>0, which "floats in front" of its parent. |
| Handler | Message handler is a protected virtual method of MWindow, which can be (and usually is) overloaded in order to customize a derived window class. |
| Input message | A message that reports an event from an input device. See Messages. |
| Invalid | Invalid values for various types. |
| Iterator | Collection iterator is a special object, which provides a safe and efficient access to the data stored in a collection (see collection classes). |
| Key | Binary input device. |
| Label | A type of window that displays information with little to no user interaction (see window classes). |
| Local pathname | Pathname which points to a local file system. See pathname. |
| Message loop | See MWindow::runMessageLoop. |
| Multithreading | Describes the support for multithreaded operations in Elgrint-based apps. |
| Online pathname | Pathname which points to a server location via FTP or HTTP/HTTPS protocols. See pathname. |
| Painting functions | MWindow functions that define graphical content inside the window. |
| Pathname | A unique identifier of a file or a directory in the local system or on the Internet. |
| Plugin | A plugin is a child window object, which has a special meaning for its parent window. |
| Presentation message | A message that reports some change in a window of this app. See Messages. |
| Property | A window class setting that can be revealed and changed freely by the developer who uses that class. |
| RELEASE mode | A standard compiler mode, which generates the final app, which can be released to users. |
| Rounded out | MRect, adjusted so that all of its components are integral values. |
| Screen window | A window object that represents the entire screen. |
| Selector | A type of window that lets a user select a value of a certain type from a predefined range (see window classes). |
| Standard form | Constructor, which has the signature WC(MWindow&,MRect), where WC is a window class. |
| System message | A message that is generated outside of the main thread of this app. See Messages. |
| Valid | Opposite of invalid. |
| Web pathname | Same as online pathname. |
| Window class | A class that creates a window object. Any class that inherits from MWindow, and MWindow itself. |
| Window object | An instance of one of the window classes. |
| Window pointer | A safe, smart pointer for a window object. See MPtr for a full description. |
| Wrapper | Window pointer wrappers are special type definitions that make the process of a window pointer creation more convenient. See WCPtr for a full description. |
