Chapter SW1 Page 1 Chapter SW 1 FUNDAMENTALS of SOFTWARE USE If You Go out in the Computer Marketplace Today, You Will Find Thou Chapter SW 1 FUNDAMENTALS OF SOFTWARE USE If you go out in the computer marketplace today, you will find thousands of different software packages. They do different things such as word processing, graphics, control computers, e-mail, calendars, compress disks or files, or control a computer. Even though the software does different tasks, software packages exhibit similarities in the way that they work. Systems & Applications Software • Systems Software • Enable applications to run – Operating System – Language Translators – Utility Programs • Applications Software In the introduction we learned that software falls into two categories: Systems software consists of programs that enable applications software to run. Systems software consists of three different types - Operating systems manage the system and the running of other programs. Language translators translate a programming language into machine language. Utility programs are tools to provide some functions that the operating system doesn’t provide. An example might be the Windows disk defragmentation program or Windows Explorer. Software Suites • Software Suites – MS/Office, Corel WordPerfect Office • Integrated Software Programs – MS/Works, Claris Works, Corel PerfectWork One type of application program is the office oriented program. Many times office oriented programs of different types are bundled together in a suite. The most popular suite is MS/Office with 80% or more of the suite market. Suites are the primary way that office programs are sold to business. Related to these are programs which compress a suite into a smaller less comprehensive package with less functions. How an office suite is organized In a suite, there are multiple components or applications that are bundled together. The components share a library of routines and data so they don’t require as much space as when each component is installed separately. Microsoft Office 2000 If you buy the MS/Office Standard package, you get Word, Excel, Outlook, and PowerPoint. If you buy the Small Business package instead, you don’t get PowerPoint but you get Publisher and Small Business Tools. If you buy Professional you get all of those plus Access and if you buy Premium, you also get FrontPage and PhotoDraw. Corel WordPerfect Office 2000 Corel has a different set of packages but some of the same types of office software. Who Owns Software? • Publisher Owns • User Licenses • Classes: – Proprietary – Shareware – Freeware Chapter SW1 Page 1 There are misconceptions about who actually owns software. The publisher owns it. They decide who can use, copy, or distribute the program. As a user, you license the software. This gives you the right to use it within the specifications of the license agreement. If you use software without the right to use it, you are stealing from the publisher. Most software is proprietary. You are expected to buy a licensed copy or just a license to use it. Many times organizations acquire a site license which allows them to run up to some maximum number of copies at a site or multiple sites. Some software is distributed as shareware. In this case, the publisher doesn’t require any payment unless you want formal documentation or support. Others ask that you register and pay after you have used the product for a certain length of time. You can copy shareware and give it to your friends. In fact, that is one way that shareware is distributed. Your friend may end up using the software and buying it. Similar to shareware is freeware except that it is totally free. It is in the public domain. Some examples are Mosiac and Pegasus Mail. Since it is free, you don’t get any support and some freeware has errors or bugs. The User Interface The manner in which a program package makes its resources available to users it its user interface. The User Interface • Command Syntax – rules of a language – for use at the system prompt • Shortcut Keystrokes – Invoke command with minimal keystrokes – Saves time Until recently, we interfaced with computers through lines of a command language. These commands had a syntax. A syntax refers to the rules that govern the structure and content of a language. That is why this interface is called command syntax. MS/DOS is an example of a command syntax user interface. Show MS/DOS prompt, dir, copy. Many programs implemented shortcut keystrokes to save time. For example, in MS/DOS if you hit F3, the last command is repeated. In DOS Wordperfect, F5 is save. Once you learn the command language and the shortcuts, performing commands or operations is quick. But, it requires training and continual use. If you go on vacation for two weeks, you may find that you have forgotten half of the shortcuts. The User Interface • GUI – Graphical User Interface – Gooey – MS/Windows, Apple/MacOS Because of the availability of powerful CPUs and high-resolution graphics screens, the GUI or graphical user interface has become popular. GUI is often shortened to gooey. We are now going to look at the elements of the MS/Windows GUI. GUI Elements: Menu • Menu Bar • Pull Down or Drop Down Menus • Icon Menus • Hyperlinks • Palettes • Tab menus • Dialog boxes Chapter SW1 Page 2 A menu is a set of options from which you can choose a desired action. There are many types of menus. Menu elements 1/2 At the top of many windows below the title bar is a menu bar showing the major command sets. You can select a menu command with the mouse or by a shortcut-keystroke (ALT-?). Once you make a selection a pull-down or drop-down menu appears. Pull down menus typically conform to some conventions. For example: The active command on the menu bar is highlighted. The default command on the drop-down menu is highlighted. The default command can be selected by hitting the Enter key. Commands are selected by using the mouse or by the shortcut key if there is one. Ghosted commands means that the choice is not currently available. A checkmark on the left means that an option is on or active. By selecting the menu item, you toggle the option on & off. Separators are used to group related commands. Menu elements (2/2) An arrow to the right of an option means that the choice leads to another pull-down menu. Ellipses (…) means that you will get another set of choices - generally a dialog box. Shortcut keystrokes that you can use for commands without the menu are sometimes shown after an item and the icon for a command is sometimes shown before. GUI Elements: Menu (Cont.) • Menu Bar • Pull Down or Drop Down Menus • Icon Menus • Hyperlinks • Palettes • Tab menus • Dialog boxes • Command Button Often menus appear as icons. An icon is a small graphic image. The desktop is an icon menu. A toolbar is an icon menu composed of toolbar icon buttons. Generally if you rest the pointer over an icon button, it will display the name. <show> A palette is a menu that enables you to choose among colors, textures, or some graphic form. <show> Tabbed menus organize a screen into file-folder-like tabs. You click on the tab to show the tab panel. <View, Toolbars, Customize> A dialog box is a type of menu. Dialog boxes generally contain command buttons which have either the name of the command or an icon on it. They represent a command such as OK, Cancel, or Close. GUI: Windows • Tiling vs. Cascading • Resizing • Moving • Minimizing and Maximizing • Scroll bars A window is a box that is overlaid over other screen information. The name of the window is in the title bar at the top. Windows can be arranged on the screen side by side or cascading them on top of one another. Tiling allows you to see some information in several windows. Cascading allows you to see as much as possible in the foreground window. You can resize a window by selecting a border, keeping the mouse depressed, and moving the mouse. Chapter SW1 Page 3 You can move a window by selecting the title bar at the top of the window, keeping the button depressed, and dragging and dropping the window to the desired location. Windows can be minimized to an icon by selecting the minimize button. They can be restored by clicking on the icon. They can be maximized by selecting the maximize button and then restored by pressing the restore button. These are close to the close button which closes the window. On the left of the title bar is a drop down menu which also has some of these commands. Scroll bars, normally on the bottom and/or left, allow you to move the information that appears in a window. GUI: Dialog Boxes & Help • Dialog Boxes – Radio-Button Boxes – Check Boxes – Text Boxes – List Boxes – Combo Box – Spin Box – Message Boxes • Online Help – & Wizards Dialog boxes are special windows that prompt for further information. This information is provided by a variety of controls. <print> Radio buttons work like radio preset station buttons - only one can be selected at a time. Check boxes differ in that more than one can be selected. Text boxes allow you to type in information. A list box is a menu of selections, only one of which can be selected. A combo box is a combination text box and list box. You can make a selection or type in information. A spin box allows you to select a value in a range. A message box is a box or window that pops up to display special information. Many programs have help and documentation that are accessed through the program. Drag and Drop • Used for – Copy – Move – Make associations Another feature of the GUI is the drag and drop.

    Table of Contents MICROSOFT WORD 1 ONE LINC What is MSWord? MSWord is a word-processing program that allows users to create, edit, and enhance text in a variety of formats. Word is a powerful word processor with sophisticated editing and formatting as well as graphic- enhancement capabilities. Word is a good program for novice users since it is relatively easy to learn and can be integrated with language learning. Word processing has become popular due to its wide range of personal, business, and other applications. ESL learners, like others, need word processing for job search, employment, and personal purposes. Word-processing skills have become the backbone of computer literacy skills. Features PARTS OF THE SCREEN The Word screen can be overwhelming for novice learners. The numerous bars on the screen such as toolbars, scroll bars, and status bar confuse learners who are using Word for the first time. It is important that learners become familiar with parts of the screen and understand the function of each toolbar but we recommend that the Standard and Formatting toolbars as well as the Status bar be hidden for LINC One level.

  • The BIAS Soundscape Planning Tool for Underwater Continuous Low Frequency Sound
    The BIAS soundscape planning tool for underwater continuous low frequency sound User Guide The BIAS soundscape planning tool BIAS - Baltic Sea Information on the Acoustic Soundscape The EU LIFE+ project Baltic Sea Information on the Acoustic Soundscape (BIAS) started in September 2012 for supporting a regional implementation of underwater noise in the Baltic Sea, in line with the EU roadmap for the Marine Strategy Framework Directive (MSFD) and the general recognition that a regional handling of Descriptor 11 is advantageous, or even necessary, for regions such as the Baltic Sea. BIAS was directed exclusively towards the MSFD descriptor criteria 11.2 Continuous low frequency sound and aimed at the establishment of a regional implementation plan for this sound category with regional standards, methodologies, and tools allowing for cross-border handling of acoustic data and the associated results. The project was the first one to include all phases of implementation of a joint monitoring programme across national borders. One year of sound measurements were performed in 2014 by six nations at 36 locations across the Baltic Sea. The measurements, as well as the post-processing of the measurement data, were subject to standard field procedures, quality control and signal processing routines, all established within BIAS based on the recommendations by the Technical Subgroup on Underwater Noise (TSG-Noise). The measured data were used to model soundscape maps for low frequent continuous noise in the project area, providing the first views of the Baltic Sea soundscape and its variation on a monthly basis. In parallel, a GIS-based online soundscape planning tool was designed for handling and visualizing both the measured data and the modelled soundscape maps.

ABSTRACT The use of vegetation in remediating contaminated soils and sediments has been researched for a number of years. Positive laboratory results have lead to the use of vegetation at field sites. The design process involved with field sites and the associated decision processes are being developed. As part of this develop- ment, a computer-based graphical user interface decision support system was designed for use by practicing environmental professionals. The steps involved in designing the graphical user interface, incorporation of the contaminant degradation model, and development of the decision support system are presented. Key words: phytoremediation, simulation INTRODUCTION Vegetation has been shown to increase the degradation of petroleum and organic contaminants in contaminated soils. Laboratory experiments have shown promising results which has led to the deployment of vegetation in field trials. The design of field trials is different than the design of a treatment system. In a field trial, the type of vegetation, use of amendments, placement and division of plots, and monitoring requirements are geared toward producing statistically measurable results.

  • Developing GUI Applications. Architectural Patterns Revisited
    Developing GUI Applications: Architectural Patterns Revisited A Survey on MVC, HMVC, and PAC Patterns Alexandros Karagkasidis [email protected] Abstract. Developing large and complex GUI applications is a rather difficult task. Developers have to address various common soFtware engineering problems and GUI-speciFic issues. To help the developers, a number of patterns have been proposed by the software community. At the architecture and higher design level, the Model-View-Controller (with its variants) and the Presentation-Abstraction- Control are two well-known patterns, which specify the structure oF a GUI application. However, when applying these patterns in practice, problems arise, which are mostly addressed to an insuFFicient extent in the existing literature (iF at all). So, the developers have to find their own solutions. In this paper, we revisit the Model-View-Controller, Hierarchical Model-View- Controller, and Presentation-Abstraction-Control patterns. We first set up a general context in which these patterns are applied. We then identiFy Four typical problems that usually arise when developing GUI applications and discuss how they can be addressed by each of the patterns, based on our own experience and investigation oF the available literature. We hope that this paper will help GUI developers to address the identified issues, when applying these patterns. 1 Introduction Developing a large and complex graphical user interface (GUI) application for displaying, working with, and managing complex business data and processes is a rather difficult task. A common problem is tackling system complexity. For instance, one could really get lost in large number of visual components comprising the GUI, not to mention the need to handle user input or track all the relationships between the GUI and the business logic components.
