Glossary |
A key or key combination that immediately executes a command from a menu.
Text that appears on the buttons of a menu to remind the user of an accelerator.
The name (such as "Arm," "Activate," or "Help") of a widget's prescribed response to an event, as defined in the widget's translations table. Actions are mapped to functions in the widget's action table.
A function that performs an action. Many action routines are supplied with Motif. X-Designer users can also write their own action routines.
A table associated with a widget that maps actions to the action routines that perform them.
An applet is a small application written in Java which is embedded in a web page and runs when the page is browsed.
The name given to the Application Shell of a generated application. This name is used as a title for that Shell's window and to identify resources that belong to that application. In X-Designer, the application class name is assigned at code generation time.
The type of Shell widget that is used for the primary window in the application.
A constraint fixing one side of a widget to one side of a sibling widget or to one side of its parent layout widget. Attachments can be made at a fixed distance or at a percentage of the layout widget's dimension.
The area reserved for buttons at the bottom of a composite widget such as a MessageBox, DialogTemplate, or FileSelectionBox.
A widget in the design hierarchy that is designated as a C++ class. In the generated code, X-Designer defines a C++ class for the widget, with named descendant widgets as members of the class.
A field of a widget structure that designates a list of callback functions and a user action. When the user action occurs on that widget, the functions on the callback list are executed.
One of the functions on a callback list.
A group of functions (callback functions) associated with a callback.
A list of character (ideograph) choices for a given typed pronunciation produced from an input method. This normally applies only to ideographic scripts.
Analyze the design of a running Motif application and create a ".xd" file containing an identical design. XD/Capture does this.
Common Gateway Interface. The CGI standard lays down the rules for running external programs in a Web HTTP server. External programs are called gateways because they open up an outside world of information to the server.
A program or shell script written in any language which conforms to the CGI standard for data communication.
The widgets that are managed by, and (if visible) contained within the boundaries of, a parent widget. In X-Designer, children widgets appear below their parents in the design hierarchy.
A widget which X-Designer treats as a place-holder when generating code. No code is generated for the Children Only widget itself, but code is generated for any of its descendants that are designated as data structures, function structures, or C++ classes.
In Form layout, an attachment of Widget A to Widget B, when Widget B is attached to Widget A. Attachment of Widget A to B, B to C, and C to A, or any larger loop, is also considered circular. Circular attachments are not allowed in Motif.
The abstract hierarchy of widget classes in Motif. Class hierarchy is distinguished from design hierarchy.
The single parameter that can be passed to a callback function.
Lines of code supplied in a dialog in X-Designer and inserted at specific points in the generated code.
Association of a name with a color.

The special resource panel that lets you set the resources of the Core, Primitive, and Manager superclasses.
The broad superclass from which all widget classes are derived.
A function generated by X-Designer that creates a Shell widget with its children.
A widget for which X-Designer generates a typedef for a data structure, and a creation procedure that sets up that type of structure and returns a pointer to it.
A widget class that is below another class in the class hierarchy. The derived class possesses all attributes of the classes above it, plus specialized attributes of its own.
The hierarchy of individual widget instances that makes up the design for an interface. Distinguished from class hierarchy.
The last field in an event specification for a translation, normally used to specify which key must be pressed.

A widget for which X-Designer produces a separate creation procedure in the generated code.
An alternative version of certain widgets derived from the Primitive class. Unlike widgets, gadgets do not require the internal creation of a window for each instance. Use of gadgets instead of widgets may or may not be advantageous, depending on your system.
Graphic Interchange Format. A file format for storing images. GIFs only store 8 bits of color information per pixel which makes them less attractive than other formats.
Fuzzy display of an icon, pushbutton, or menu option. In X-Designer, graying out denotes that the command is inactive.
A resource value that is generated into the source code, not into the X resource file. Hard-wired resource values cannot be changed without remaking the application.
Acronym for "HyperText Markup Language". HTML is a public domain format which uses only printable characters and can, therefore, be created in any text editor. It is also a standard used by many applications.
HyperText Transfer Protocol. At the beginning of every URL, you see the four letters "http". They tell the Web server how your browser intends to communicate with it. When you connect to a World Wide Web server, both systems use this protocol to transfer the document from the server to your system. For more detailed information see:
http://info.cern.ch/hypertext/WWW/Protocols/HTTP/HTTP2.html
Text, graphics and other media connected through links.
Integrated Development Environment. An application comprising a set of integrated tools which help you to develop programs. IDEs normally include at least a compiler, debugger and code editor.
To possess the attributes of a superclass. Derived widget classes are said to inherit from their superclasses.
Indicates the window or component within a window that receives keyboard input. Sometimes called keyboard focus.
An individual widget data structure. Widget instances are specific examples of widget classes. To instantiate a widget means to create an instance of a widget class.
A network internal to an organization. There is usually no firewall between the computers on an intranet but there probably is one between the intranet and the internet.
Java is a programming language with libraries specifically geared for the Internet environment. Java is highly portable, object-oriented and interpreted. It is threaded, has automatic storage management and uses exceptions.

Microsoft Foundation Classes. A set of base classes for building user interfaces to run on Microsoft Windows.
Multimedia Internet Message Extension. MIME provides a way of extending the power of Web browsers to handle graphics, sound, multimedia and anything else except text. HTML handles only text--everything else is an extension. MIME is also used for binary email attachments. Browsers recognize MIME types in categories and file types, separated by a slash (such as image/gif). If you've registered a MIME type, the browser decodes the file and launches a helper application.
A single character (often the initial character) of a menu or menu selection, which initiates the selection when the menu is displayed and the character is pressed on the keyboard.
Lines of code inserted at the beginning of the generated primary module and the stubs file.

The selection of more than one widget from the construction area.
The fixed distance, in pixels, between two attached widgets, or between a widget and the side of the layout widget to which it is attached.
Said of an attachment. The origin of an attachment is the widget from which the attachment was made.
A term used in connection with Java code. A package is like a library in C. It provides a way to group together related object files. Each source file should be labelled with the name of the package to which it belongs. The package name is based on the directory containing the source file. Source files can "import" packages that they wish to use.
The options menu at the top of some resource panels that lets you move from one page of resources to another.
A widget that manages and determines the layout of its children. In X-Designer, parent widgets are shown above their children in the design hierarchy.
When replaying scripts--stop replaying and wait at the current point in the script.
Association of a name with a pixmap.
Attachment of one side of a widget at a specified percentage of the width or height of its parent Form. This type of attachment adjusts to the current Form dimensions.
A code prelude inserted just before the given widget is created.
A piece of code inserted into the generated files. See pre-create prelude, pre-manage prelude, module prelude.
A code prelude inserted after the given widget is created but before it is managed. Commonly used to set up client data for callbacks.
The code module generated by X-Designer that contains the creation procedures for your interface.
In the context of the layout editor--the primary selection is the widget which was selected last. When aligning widgets, any other selected widgets will be aligned to the primary selection.
In the Motif class hierarchy, a broad superclass from which all the button-type widgets and several other classes are derived. The Primitive widget is derived from the Core widget.
A proxy server is a system that caches items from other servers to speed up access. On the Web, a proxy first attempts to find data locally, and if it's not there, fetches it from the remote server where the data resides permanently.
As used in this document, a query string refers to the part of a URL which appears after a question mark (?). The query string has a standard format which is understood by applications such as search engines.
Toggle buttons grouped inside a RadioBox, or inside a Menu or RowColumn with the "Radio behavior" resource set to "Yes." Only one radio button in the group may be selected at a time.
A settable field in a widget data structure. Resources control many aspects of a widget's appearance and behavior. Resources can be set by the designer or the user, or both.
An interactive screen in X-Designer that lets you specify resource values for a widget.
A prelude inserted at the beginning of the generated X resource file. Commonly used to add loose resource bindings for the entire application rather than for individual widgets.
When running in record mode, the replay tool creates scripts containing a description of the actions performed on an application. In replay mode, the replay tool can read scripts and perform the actions described therein. Scripts are plain text and consist of keywords and variables.
In the context of the layout editor--the secondary selection is any widget other than the primary selection. When aligning widgets, those which are the secondary selection will be aligned to the primary selection.
The widget whose icon is currently highlighted in the design hierarchy. A widget must be selected before anything can be done to it in X-Designer.
The business end of a client/server setup, a server is usually a computer that provides the information, files, Web pages, and other services to the client that logs on to it. The word server is also used to describe the software and operating system designed to run server hardware. The client/server setup is analogous to a restaurant with waiters and customers.
Standard Generalized Markup Language is a data encoding that allows the information in documents to be shared--either by other document publishing systems or by applications for electronic delivery, configuration management, database management, inventory control, etc. Defined in ISO 8879:1986 Information Processing Text and Office Systems; Standard Generalized Markup Language (SGML).

(1) An area at the bottom left of the main X-Designer screen and the Layout Editor which provides information relating to the menu option, toolbar button or widget at the current cursor location.
(2) When an input method is active, an extra text line appears in the active window (usually at the bottom left). This informs the user of the current mode with respect to the input method along with any other information the input method wishes to convey.
A generated file containing #include statements, function declarations and empty braces for callbacks.
A widget class that is derived from another class.
A widget class from which another class is derived.
Hypertext help information, consisting of a document name and a hypertext marker within the document.
Used in AppGuru to describe an example user interface to be used as the starting point of a new design.
A client is the "customer" side of a client/server setup. For example, to download something from an ftp site, you use ftp client software. A thin clint refers to a clint which only provides the thin layer of user interface. All of the "business" is performed in the server.

One of the predefined data structures in the Motif toolkit, or other toolkits, that are used as building blocks for graphical user interfaces.
An attachment of one widget to another within the Form.
(1) The name used to distinguish a widget instance in the X resource file. This name does not have to be the same as the variable name and does not have to be unique.
