Data Widgets Effective TCL/TK Programming: Writing Better Programs in TCL and TK by Mark Harrison, The Tcl scripting language and the Tk toolkit create a powerful programming environment for building graphical user interfaces. With two lines of code you can create a simple button; with two hundred lines of code, a desktop calculator; and with a thousand lines of code, an industrial-strength groupware calendar and appointment minder. Your applications run on all of the major platforms: UNIX, Windows 95/NT, and Macintosh. You can even embed your programs in a Web page to make them available online. Mark Harrison and Michael McLennan, two noted Tcl/Tk experts, combine their extensive experience in this practical programming guide. It is ideal for developers who are acquainted with the basics of Tcl/Tk and are now moving on to build real applications. "Effective Tcl/Tk Programming" shows you how to build Tcl/Tk applications effectively and efficiently through plenty of real-world advice. It clarifies some of the more powerful aspects of Tcl/Tk, such as the packer, the canvas widget, and binding tags. The authors describe valuable design strategies and coding techniques that will make your Tcl/Tk projects successful. You will learn how to: Create interactive displays with the canvas widget Create customized editors with the text widget Create new geometry managers, like tabbed notebooks or paned windows Implement client/server architectures Handle data structures Interface with existing applications Package Tcl/Tk code into reusable libraries Deliver Tcl/Tk applications that are easy to configure and install Embed applications in a Web page Build applications that will run on multiple platforms Throughout the book, the authors develop numerous applications and a library ofreusable components. Learn from their approach, follow their strategies, and steal their code for your own applications! But don't bother retyping all of the examples.
Python with CDROM by Harvey M. Deitel, The authoritative DEITEL™ LIVE-CODE™ introduction to Python programming This new book by the world's leading programming language textbook authors carefully explains how to use Python as a general-purpose programming language and how to program multi-tier, client/server, database-intensive, Internet- and Web-based applications. Dr. Harvey M. Deitel and Paul J. Deitel are the founders of Deitel & Associates, Inc., the internationally-recognized corporate-training and content-creation organization specializing in Python, Visual Basic(R) .NET, C#, Visual C++(R) .NET, Java™, C++, C, XML, Perl, Internet, Web, wireless and object technologies. The Deitels are the authors of several worldwide #1 programming-language textbooks, including "Java How to Program, 4/e, C++ How to Program, 3/e" and "Internet & World Wide Web How to Program, 2/e." In "Python How to Program," the Deitels and their colleagues, Jonathan Liperi and Ben Wiedermann, discuss topics you need to build complete Web-based applications, including: HTML/XHTML™ /CSS™ Python Server Pages/CGI Networking/Sockets GUI/Tkinter/Python Mega Widgets PyOpenGL/Multimedia/Accessibility Databases/DB-API/SQL File Processing/Serialization Modules/Classes/Class Attributes Class Customization/Method Overriding Control Structures/Functions/Inheritance String Manipulation/Regular Expressions Lists/Tuples/Dictionaries/Data Structures Process Management/Multithreading Interprocess Communication Exceptions/XML Processing Security/Restricted Execution "Python How to Program" includes extensive pedagogic features: Hundreds of LIVE-CODE™ programs with screen captures that show exact outputs World Wide Web andInternet resources to encourage further research Hundreds of tips, recommended practices and cautions--all marked with icons "Python How to Program" is the centerpiece of a complete family of resources for teaching and learning Python, including Web sites (www.deitel.com, www.
Data link - In telecommunication a data link is the means of connecting one location to another for the purpose of transmitting and receiving data. It can also be an assembly, consisting of parts of two data terminal equipments (DTEs) and the interconnecting data circuit, that is controlled by a link protocol enabling data to be transferred from a data source to a data sink. Data Processor - In data processing or information processing, a Data Processor or Data Processing Unit or Data Processing System is a system which processes data which has been captured and encoded in a format recognizable by the data processing system or has been created and stored by another unit of an information processing system. Global Oceanographic Data Archaeology and Rescue Project - The Global Oceanographic Data Archaeology and Rescue Project, or GODAR Project was established to increase the volume of historical oceanographic data available to climate change and other researchers. The project attempts to locate ocean profile and plankton data sets not yet in digital form, digitizes these data, and ensures their submission to national data centers and the World Data Center system (WDC). Resource construction set - A resource construction set is a computer program with a relatively easy to use point-and-click interface for creating and editing data structures representing GUI widgets for programs running under GEM. The original resource construction set, GEM RCS, was written by Digital Research. datawidgets
