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. -

Whereas better and faster CPUs used to mean higher clock rates, better and faster CPUs now means more cores per chip. Additionally, GPUs are emerging as powerful parallel processing devices when computing particular types of problems. Computers today have a tremendous amount of varied parallel processing power. Utilizing these different devices typically means wrestling with varied architecture, vendor, or platform specific programming models and code. OpenCL is an open-standard designed to provide developers with a standard interface for programming varied (heterogeneous) parallel devices. This standard allows single source codes to define algorithms to solve vectorized problems on various parallel devices on the same machine. These programs are also portable. -

Understanding and Using Windows API Calls
09_bullen.qxd 1/7/05 10:00 AM Page 255 CHAPTER 9 Understanding and Using Windows API Calls In the Programming with the Windows API chapter of our Excel 2002 VBA Programmers Reference, we approached the subject of using Windows API calls by explaining how to locate the definitions for various functions on the MSDN Web site and translate those functions for use in VBA. The idea was to enable readers to browse through the API documentation and use anything of interest they found. In reality, extremely few people use Windows API calls in that manner; indeed, trying to include previously unexplored API calls in our Excel applications is very likely to result in a maintenance problem, because it’s doubtful that another developer will understand what we were trying to do. Instead, most of us go to Google and search the Web or the news- groups for the answer to a problem and find that the solution requires the use of API calls. (Searching Google for “Excel Windows API” results in more than 200,000 Web pages and 19,000 newsgroup posts.) We copy the solution into our application and hope it works, usually without really understanding what it does. This chapter shines a light on many of those solutions, explaining how they work, what they use the API calls for, and how they can be modified to better fit our applications. Along the way, we fill in some of the conceptual framework of common Windows API tech- niques and terminology. By the end of the chapter, you will be comfortable about including API calls in your applications, understand how they work, accept their use in the example applications we develop in this book and be able to modify them to suit your needs. -
