Volume 24, Number 2, June 2003 Ada User Journal 67 Editorial In this issue of the Ada User Journal we continue our close watch on the on-going Ada language revision process. Experience with Ada 95 has brought about the urge to push the language forward along the two main avenues of its advanced support: high-integrity real-time programming and object-oriented programming (OOP). After covering the former topic, we now turn our attention to the latter and have the pleasure of hosting S Tucker Taft, who illustrates for us the rationale and the outline of the proposed completion of the OOP language support in Ada 200Y. Our readers should know that the editing of the News section is by far the most effort-intensive part of the volunteer-based production of the Ada User Journal. Interestingly, this is so because of the health of the language user community and the impressive wealth of information that flows in the various channels monitored by our News editor. Over the last year we have seen the News section often account for about half of every 64-page issue. The feedback we receive suggests that our readers find the News section useful and informative. They should as well know that the section contents are only a small fragment (but hopefully a representative overview) of a much larger, some 30 times larger, material, which is to be logged, linked and excerpted. All in all a major effort, which may sometimes take longer than anticipated. Please, bear with us while we continue this effort to produce an enjoyable and timely journal.

  • 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.

  • 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.
