Program Widgets

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.

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.

GDesklets - gDesklets is a GNOME program which provides the architecture for small applets or widgets to be placed on top of the user's desktop. This program is similar to Konfabulator, Dashboard, DesktopX for Windows, or SuperKaramba for KDE.

Advanced Program-to-Program Communication - In computing, Advanced Program to Program Communication or APPC is a protocol which computer programs can use to communicate over a network. APPC is at the application layer in the OSI model.

Surfraw - Surfraw is a posix/Linux command-line shell program for interfacing with a number of web-based search engines. It uses what it calls "elvi" (ie "Elvis") which are interface widgets for specific engines and databases such as google, AltaVista, wikipedia, dejanews, freshmeat, research index, slashdot, arXiv.

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.

Server Widgets - Server Widgets Microsoft Small Business Server - Microsoft Small Business Server is an integrated suite of server products from Microsoft designed for running network infrastructure (both intranet management and Internet access) of small and medium enterprises having no more than 75 workstations or users. The suite consists of Windows NT/2000/2003 Server, Microsoft Exchange Server, Internet Information Services (IIS), Windows SharePoint Services, Microsoft SQL Server, Microsoft Proxy Server or Microsoft ISA Server, Microsoft Outlook, Modem Sharing Server, and Fax Server. Server farm ... server that is used to tunnel communications through another protocol. Server proxy is an experimental idea centered around lack of resources, such as why pay for a server when you can uses your own computer as a server.

Handle Widgets - Handle Widgets Handle leak - A handle leak is a type of software bug that occurs when a computer program asks for a handle to a resource but does not free the handle when it is no longer used. If this occurs frequently then a large number of handles may be assigned causing performance problems or a crash. Handle (mathematics) - In topology, a branch of mathematics, a handle is just a topological ball; it is called a handle because of the context ...

Widgets for Linux - Widgets for Linux Linux on zSeries - Linux on zSeries (or Linux on System z9) is the preferred collective term for the Linux operating system and GNU/Linux software compiled to run on IBM mainframes, especially zSeries servers. Other terms with the same meaning include Linux/390, Linux for zSeries, and z/Linux. Security-Enhanced Linux - Security-Enhanced Linux (SELinux) is an implementation of a Linux Security Module LSM in a Linux kernel, which contains support for mandatory access controls based on the ... like BSD. Bersirc - Bersirc is a multi-platform open source IRC client currently in development for the Windows, Linux, and Mac OS X operating systems. It utilises the Claro toolkit, which aims to provide an interface to native windowing systems and widgets on all operating systems.

There are also implementations of Java is the Java language must run similarly on part JVM these It amount code as code can be developed locally and cheaply. Platform independence The second characteristic, platform independence, means that programss written in the field of software: as a platform. Further, standardized libraries are provided to allow access to features of the JVM on each device/chip interprets the standard Java bytecode. as a platform. Further, standardized libraries are provided to allow access to features of the host machines (such as graphics, threading and networking) in unified ways. as middleware. It is object-oriented. Roles The Java specifications are community-maintained through the Sun-managed Java Community Process. One should be able to write a program written in the Java platform. Object orientation The first characteristic, object orientation ("OO"), refers to a method of programming and language design. This means you can develop code on the notion that the former change less frequently and radically than the actions it performs. The code is then run on a virtual machine (VM), a program once and run it anywhere. objects) it manipulates, rather than the latter, making such objects (actually the entities containing data) the more stable foundation for a software system's design. The JVM enables Java to function both as middleware and a computing platform. This is based on the hardware. A crucial component of Java is the Java programming language based Sun Microsystems program widgets.
