  • Tkgecko: Another Attempt for an HTML Renderer for Tk Georgios Petasis
    TkGecko: Another Attempt for an HTML Renderer for Tk Georgios Petasis Software and Knowledge Engineering Laboratory, Institute of Informatics and Telecommunications, National Centre for Scientific Research “Demokritos”, Athens, Greece [email protected] Abstract The support for displaying HTML and especially complex Web sites has always been problematic in Tk. Several efforts have been made in order to alleviate this problem, and this paper presents another (and still incomplete) one. This paper presents TkGecko, a Tcl/Tk extension written in C++, which allows Gecko (the HTML processing and rendering engine developed by the Mozilla Foundation) to be embedded as a widget in Tk. The current status of the TkGecko extension is alpha quality, while the code is publically available under the BSD license. 1 Introduction The support for displaying HTML and contemporary Web sites has always been a problem in the Tk widget, as Tk does not contain any support for rendering HTML pages. This shortcoming has been the motivation for a large number of attempts to provide support from simple rendering of HTML subsets on the text or canvas widgets (i.e. for implementing help systems) to full-featured Web browsers, like HV3 [1] or BrowseX [2]. The relevant Tcl Wiki page [3] lists more than 20 projects, and it does not even cover all of the approaches that try to embed existing browsers in Tk through COM or X11 embedding. One of the most popular, and thus important, projects is Tkhtml [4], an implementation of an HTML rendering component in C for the Tk toolkit. Tkhtml has been actively maintained for several years, and the current version supports many HTML 4 features, including CCS and possibly JavaScript through the Simple ECMAScript Engine (SEE) [5].

  • Entice – Embedding Firefox in Tk
    Entice – Embedding Firefox in Tk Steve Landers Digital Smarties [email protected] Abstract This paper describes Entice - a Tcl/Tk extension that allows multiple Firefox windows to be embedded into Tk and controlled from a Tcl/Tk application. Entice brings to Tcl/Tk applications on X11 similar functionality to that provided by using Internet Explorer and Optcl on Windows. The paper describes the use of the TkXext extention to embed Firefox, the use of web technologies (XUL, Javascript and AJAX) and a small embedded web server for communication with Firefox. Future developments such as providing a generalised cross-platform/cross-browser API will be discussed. Background On Windows it is possible to embed instances of Internet Explorer (IE) into a Tk application using COM – via the Optcl[1] or Tcom[2] extensions. This makes practical a new genre of hybrid client/web applications such as NewzPoint[3] (which displays multiple web pages in a two-tiered tab layout arrangement using IE as the display engine). Entice is an attempt to provide the same (or similar) functionality for Unix/Linux platforms - in the first instance, Tk under X11 but potentially under other windowing systems such as MacOS X Aqua (although that is beyond the scope of this paper). There are three distinct requirements in doing this: • embedding a browser in Tk • communicating with the browser (i.e. sending content) • controlling the browser from Tcl A browser in a Tk application? There are a number of approaches to providing a browser within a Tk application: • use a Tk extension that “wraps” a browser library • use a Tk browser extension • embed an external browser window into a Tk frame The first approach was used in the TkGecko[4] project, which wraps the Mozilla Gecko rendering engine as a Tk extension.

  • PDF Booklet for Ebook Readers, Excerpt of This Wiki
    AndroWish Executive Summary Tcl (Tool Command Language) is a very powerful but easy to learn dynamic programming language, suitable for a very wide range of uses, including web and desktop applications, networking, administration, testing and many more. Open source and business-friendly, Tcl is a mature yet evolving language that is truly cross platform, easily deployed and highly extensible. Tk is a graphical user interface toolkit that takes developing desktop applications to a higher level than conventional approaches. Tk is the standard GUI not only for Tcl, but for many other dynamic languages, and can produce rich, native applications that run unchanged across Windows, Mac OS X, Linux and more. AndroWish allows to run desktop Tcl and Tk programs almost unaltered on the Android Platform while it opens the door to script a rich feature set of a mobile platform. Its sibling undroidwish uses the same code base and offers a similar feature set on various desktop and embedded platforms. Quick Links Tcl/Tk 8.6 manual, ble, borg, dmtx, modbus, muzic, rfcomm, sdltk, snap7, tclcan, topcua, usbserial, uvc, wmf, v4l2, zbar, zipfs, Documentation list of extensions, list of releases, environment, undroidwish, undroidwish command line switches PDF booklet for eBook readers, excerpt of this wiki Development AndroWish SDK, building#1, building#2, examples Downloads AndroWish-debug.apk, AWSDK.zip Features Native Tcl/Tk 8.6 port for Android (version 2.3.3 or above) available for ARM and x86 processors.

    7th USENIX Tcl/Tk Conference February 14-18, 2000 Austin, Texas, USA Tutorial Sessions Monday, Feb. 14 to Tuesday, Feb. 15, 2000 Please select one morning and one afternoon tutorial. Sorry, no partial registrations are allowed. Monday, February 14, 2000 Morning Sessions (9:00 am - 12:30 pm) M1am: Effective Tcl/Tk Programming Michael McLennan, Cadence Design Systems, Inc. Who should attend: Programmers and managers who are using Tcl/Tk to build real-world applications. This tutorial assumes a working knowledge of Tcl/Tk and goes beyond that to show how nontrivial Tcl/Tk programs are put together. Topics include: • How to use the Tk canvas widget to synthesize new types of widgets • How to use binding tags to add new widget behaviors • How to organize Tcl code into reusable libraries and packages. These techniques come together to create professional-looking applications that are easier to maintain and extend. Michael McLennan has been a Tcl/Tk enthusiast since 1992. He has taught more than 100 Tcl/Tk courses, and is co-author of Effective Tcl/Tk Programming and Tcl/Tk Tools. He also developed [incr Tcl], an object-oriented extension of Tcl/Tk. Michael, who received a Ph.D. in 1990 from Purdue University, is currently an Architect at Cadence Design Systems, Inc. M2am: XML and Tcl/Tk Steve Ball, Zveno Pty. Ltd. Who should attend: Developers who wish to add XML support to their applications, use XML for storing data, or process XML documents using Tcl. XML is set to revolutionize not only the Web but also many industries and businesses, as it allows easy, robust data exchange between machines.

  • Capítulo 8. Telepatología Estática
    Capítulo 8. Telepatología Estática FRANCISCO G. LA ROSA, ERNESTO MORO RODRÍGUEZ 8.1.- Introducción La Telepatología Estática se define como la práctica de patología a distancia basada en la transmisión por vías de telecomunicación de imágenes fijas o estacionarias de especímenes patológicos para su correspondiente interpretación y diagnóstico. Incluidas también en estas transmisiones están la transferencia de información demográfica del paciente, historia clínica, números de identificación, datos de laboratorio, estadísticas, etc. En telepatología estática, es necesario que la persona que selecciona y transmite las imágenes patológicas sea un profe- sional patólogo competente y con conocimientos básicos de patología informática. Al otro lado de las vías de comunicación, es el telepatólogo el que recibe las imágenes electrónicas y efec- túa su evaluación y diagnóstico basado en la información clínica proporcionada. Seguidamente el telepatólogo envía un reporte con sus resultados usando vías de telecomunicación. Dentro de la práctica de patología debe tenerse siempre presente que ésta no se limita al área del diagnóstico médico sino que también incluye las áreas de educación y de investigación. El tiempo mínimo aproximado que puede demorar una consulta por telepat ología estática es de una hora, esto cuando se usan cámaras de TV o cámaras digitales para la captura de las imágenes. En caso del uso de imágenes obtenidas con fotografía de diapositivas (i.e. Kodach- rome, Ektachrome, Fujichrome), seguidas por escaneado, este tiempo puede prolongarse has- ta no más de 3 horas (véase sección 8.2.2a). En la práctica, es importante considerar que el tiempo de consulta por medio de telepatología estática depende en mucho de la disponibilidad del telepatólogo que recibe el caso y de la complejidad del mismo.
