An Introduction to the X Window System Introduction to X's Anatomy
An Introduction to the X Window System Robert Lupton This is a limited and partisan introduction to ‘The X Window System’, which is widely but improperly known as X-windows, specifically to version 11 (‘X11’). The intention of the X-project has been to provide ‘tools not rules’, which allows their basic system to appear in a very large number of confusing guises. This document assumes that you are using the configuration that I set up at Peyton Hall † There are helpful manual entries under X and Xserver, as well as for individual utilities such as xterm. You may need to add /usr/princeton/X11/man to your MANPATH to read the X manpages. This is the first draft of this document, so I’d be very grateful for any comments or criticisms. Introduction to X’s Anatomy X consists of three parts: The server The part that knows about the hardware and how to draw lines and write characters. The Clients Such things as terminal emulators, dvi previewers, and clocks and The Window Manager A programme which handles negotiations between the different clients as they fight for screen space, colours, and sunlight. Another fundamental X-concept is that of resources, which is how X describes any- thing that a client might want to specify; common examples would be fonts, colours (both foreground and background), and position on the screen. Keys X can, and usually does, use a number of special keys. You are familiar with the way that <shift>a and <ctrl>a are different from a; in X this sensitivity extends to things like mouse buttons that you might not normally think of as case-sensitive. -

A Successor to the X Window System
Y: A Successor to the X Window System Mark Thomas <[email protected]> Project Supervisor: D. R¨uckert <[email protected]> Second Marker: E. Lupu <[email protected]> June 18, 2003 ii Abstract UNIX desktop environments are a mess. The proliferation of incompatible and inconsistent user interface toolkits is now the primary factor in the failure of enterprises to adopt UNIX as a desktop solution. This report documents the creation of a comprehensive, elegant framework for a complete windowing system, including a standardised graphical user interface toolkit. ‘Y’ addresses many of the problems associated with current systems, whilst keeping and improving on their best features. An initial implementation, which supports simple applications like a terminal emulator, a clock and a calculator, is provided. iii iv Acknowledgements Thanks to Daniel R¨uckert for supervising the project and for his help and advice regarding it. Thanks to David McBride for his assistance with setting up my project machine and providing me with an ATI Radeon for it. Thanks to Philip Willoughby for his knowledge of the POSIX standard and help with the GNU Autotools and some of the more obscure libc functions. Thanks to Andrew Suffield for his help with the GNU Autotools and Arch. Thanks to Nick Maynard and Karl O’Keeffe for discussions on window system and GUI design.

MIT 150 | Project Athena - X Window System Users and Developers Conference, Day 1 [3/4] 1/14/1987
MIT 150 | Project Athena - X Window System Users and Developers Conference, Day 1 [3/4] 1/14/1987 [MUSIC PLAYING] PALAY: My name is Andrew Palay I work at the Information Technology Center at Carnegie Mellon University. For those who don't know, the Information Technology Center is a joint project between Carnegie Mellon University and IBM. It also has some funding from the National Science Foundation. This talk is going to cover the Andrew toolkit. I'd like to begin this talk by providing a short example of what the toolkit's all about. In particular, how I made this slide. And actually some of the other slides. So I basically had the editor. In this case, I had typed in the text. And I selected a spot of the text and essentially asked to add a raster. This particular place, I added a raster. This object that we add into these will be referred to, and are referred to by the toolkit, as insets. The inset comes up as its default size, given that I've added nothing to it. I then request to read a known raster from the file, And this point, in this case the ITC logo. If you note, the actual inset itself hasn't increased in size to accommodate the raster image. The user has control over that size, can actually make it larger or smaller. Later in the talk, another slide you will see actually has a drawing. In this case, I selected areas that I wanted the drawing, actually created the drawing in place. -
