    Visual Component Library VCL Autor: I. Stepanenko Fecha: Monday 27th of September 2021 04:09:10 PM VCL (Visual Component Library) es un marco de trabajo desarrollado por Borland basado en objetos visuales que tienen como finalidad diseñarframes para las aplicaciones que se han programado para Windows y diseñada bajo el concepto de componente: propiedades, métodos y eventos. Está estructuralmente y visualmente sincronizado con Windows, pues el aspecto de las ventanas, los botones o los accesos a internet, etc. son similares. Actualmente es propiedad de CodeGear, de Embarcadero Technologies. Está escrita en Object Pascal (orientado a objetos) por lo que la VCL es una librería usada por los entornos de desarrollo Delphi y C++ Builder. Al hablar de este tipo de bibliotecas o toolkits, se hace mención implícitamente a la programación orientada a objetos, pues los componentes son clases predeterminadas, haciendo su uso más sencillo, visual y cómodo. Se diferencian dos tipos de componentes. Componentes visuales Entre los visuales se distinguen los botones, las etiquetas, las formas y demás elementos visibles. Componentes no visuales Entre los no visuales están los temporizadores, las conexiones a bases de datos y demás elementos sin interfaz gráfica. Clases más importantes Aunque no todas las clases hacen referencia a componentes concretos algunas realizan tareas de gestión interna y se utilizan como clases bases de las cuales derivan otras clases mediante la herencia. VCL es bastante profundo y complicado; no obstante, las clases que forman la parte superior jerárquica son clases abstractas y son: Artículo descargado de www.masterhacks.net | 1 Visual Component Library VCL Autor: I.

  • Using Gtkada in Practice
    143 Using GtkAda in Practice Ahlan Marriott, Urs Maurer White Elephant GmbH, Beckengässchen 1, 8200 Schaffhausen, Switzerland; email: [email protected] Abstract This article is an extract from the industrial presentation “Astronomical Ada” which was given at the 2017 Ada-Europe conference in Vienna. The presentation was an experience report on the problems we encountered getting a program written entirely in Ada to work on three popular operating systems: Microsoft Windows (XP and later), Linux (Ubuntu Tahr) and OSX (Sierra). The main problem we had concerned the implementation of the Graphical User Interface (GUI). This article describes our work using GtkAda. Keywords: Gtk, GtkAda, GUI 1 Introduction The industrial presentation was called “Astronomical Ada” because the program in question controls astronomical telescopes. 1.1 Telescopes The simplest of telescopes have no motor. An object is viewed simply by pointing the telescope at it. However, due to the rotation of the earth, the viewed object, unless the telescope is continually adjusted, will gradually drift out of view. To compensate for this, a fixed speed motor can be attached such that when aligned with the Earth’s axis it effectively cancels out the Earth’s rotation. However many interesting objects appear to move relative to the Earth, for example satellites, comets and the planets. To track this type of object the telescope needs to have two motors and a system to control them. Using two motors the control system can position the telescope to view anywhere in the night sky. Our Ada program (SkyTrack) is one such program. It can drive the motors to position the telescope onto any given object from within its extensive database and thereafter Figure 1 - SkyTrack GUI follow the object either by calculating its path or, in the The screen shot shown as figure 1 shows the SkyTrack case of satellites and comets, follow the object according to program positioning the telescope on Mars.

  • The Desktop (Overview)
    The desktop (overview) The desktop is the main screen area that you see after you turn on your computer and log on to Windows. Like the top of an actual desk, it serves as a surface for your work. When you open programs or folders, they appear on the desktop. You can also put things on the desktop, such as files and folders, and arrange them however you want. The desktop is sometimes defined more broadly to include the taskbar and Windows Sidebar. The taskbar sits at the bottom of your screen. It shows you which programs are running and allows you to switch between them. It also contains the Start button , which you can use to access programs, folders, and computer settings. On the side of the screen, Sidebar contains small programs called gadgets. The desktop, taskbar, and Sidebar Where did my desktop go? Because programs run on top of the desktop, the desktop itself is often partially or completely hidden. But it's still there, underneath everything. To see the whole desktop without closing any of your open programs or windows, click the Show Desktop button on the taskbar. The desktop is revealed. Click the icon again to restore all of your windows to the way they were. Desktop Training Session Handout Page 1 http://ict.maxwell.syr.edu/vista/ Working with desktop icons Icons are small pictures that represent files, folders, programs, and other items. When you first start Windows, you'll see at least one icon on your desktop: the Recycle Bin (more on that later).

Like human–computer interaction (HCI), it draws from many disciplines and has links to a wide variety of topics. In this chapter, we briefly describe the history of 3D UIs to set the stage for the rest of the book. We also present a 3D UI “roadmap” that posi- tions the topics covered in this book relative to associated areas. After reading this chapter, you should have an understanding of the origins of 3D UIs and its relation to other fields, and you should know what types of information to expect from the remainder of this book. 2.1. History of 3D UIs The graphical user interfaces (GUIs) used in today’s personal computers have an interesting history. Prior to 1980, almost all interaction with com- puters was based on typing complicated commands using a keyboard. The display was used almost exclusively for text, and when graphics were used, they were typically noninteractive. But around 1980, several technologies, such as the mouse, inexpensive raster graphics displays, and reasonably priced personal computer parts, were all mature enough to enable the first GUIs (such as the Xerox Star). With the advent of GUIs, UI design and HCI in general became a much more important research area, since the research affected everyone using computers. HCI is an 11 30706 02 pp011-026 r1jm.ps 5/6/04 3:49 PM Page 12 12 Chapter 2 3D User Interfaces: History and Roadmap 1 interdisciplinary field that draws from existing knowledge in perception, 2 cognition, linguistics, human factors, ethnography, graphic design, and 3 other areas.

Introduction The power engineering domain uses both models and classic methods of operational research and the most recent ones are based on artificial intelligence for solving a large number of optimization problems. In this context, this paper presents an optimization software library for the power engineering domain, to solve several applications. The programs use classic operational research methods dedicated for linear and nonlinear optimization problem solving and those specific to graphs theory. The software library synthesizes the experience accumulated in this field at the Politehnica University of Timisoara, Power Systems Department in Romania.
