15 1. Graphical User Interfaces


The Status and Prompt Area is located below the Main Menu and the Graphics Window. This area displays information, prompts, and instructions based on the current status of the program. For some dialog boxes, it also displays the name and a brief description of the command to be executed.

Yes, GUI helps the user to understand the functionalities present within the computer through Graphical icons and a click on the icon initiates the action and the desired communication of the user. It was designed and priced for high-end corporate workstations. Most modern operating systems provide both a GUI and some level of a CLI, although the GUIs usually receive more attention. The GUI is usually WIMP-based, although occasionally other metaphors surface, such as those used in Microsoft Bob, 3dwm, or File System Visualizer.

What are the 4 features of a graphical user interface GUI )?

the four features of A Graphical User Interface (GUI) are constituted of four main parts – Windows, Icons, Menus and Pointer. They are also the Main Components of the Interface, also known as the WIMP system.

Unless you’ve been living in the jungle for the last 30 years like our primate friends, you’ve probably heard of Microsoft Windows and Apple Mac OS X, both of which are operating systems that come with their own GUIs. Some other GUIs currently used include Chrome OS, GNOME, and KDE, which are GUIs for Linux , and Android . The main idea is to present self-explanatory (or at least guessable!) picture-like doodads, so that simply moving them around and clicking will result in user joy.

What language is used for UI design?

UI Developer Skills & Responsibilities
Are skilled in modern application programming languages, such as Java, . Net, AJAX, PHP, XHTML and Ruby. Use Adobe Creative Suite programs, e.g., Photoshop, Illustrator, Flash & Flex to mockup UI elements.

This is a nice little application that demonstrates the vast majority of the widgets that are included with wxPython. The demo allows a developer to view the code in one tab and run it in a second tab. You can even edit and re-run the code in the demo to see how your changes affect the application. For example, titles, labels, figure properties and variables may all be changed using the MATLAB command-line interface. Figures can be printed using the MATLAB’s print command, as normal.

Of course, text characters will probably always be involved at some point (for example, doing a web search or writing that blog article would be super hard using just icons!). As said above, there are a lot of standards and GUI delines for a programmer to design and develop a GUI. A good GUI provides a lot of freedom to users like backtracking to the last step. A user with no computer knowledge can literally start learning about the machine because of GUI as it provides scope for users to explore and provides discoverability. This is particularly inconvenient because you have to literally feed-in commands for each and every action. If there is no GUI, we have to open a command prompt and add the application command line Interface and feed instructions to start an application, run the video player, etc. In the above screen, if you want to access or start an application, say a video player, then all we need is to click the VLC Media player icon using the pointer.

A simple case study of displaying and interacting with some biomedical data is used to illustrate the basics of GUI creation using the MATLAB ‘guide’ tool. Concepts such as adding components to the GUI, controlling their behavior in response to different events and callback functions are described. The idea of maintaining state between different callback function calls is also covered.

  • Inputting commands manually also offers precision that a WYSIWYG option in a GUI interface might not provide.
  • Users interact with information by manipulating visual widgets, which are designed to respond in accordance with the type of data they hold and support the actions necessary to complete the user’s task.
  • Those who write code know the command codes they need to include and don’t want to waste time pointing and clicking if it’s not necessary.
  • Graphical user interface applications are self descriptive, feedback is typically immediate, and visual cues encourage and steer discoverability.

This would also mean that traditional test coverage criteria are probably not adequate any longer and have to be replaced by a more property- or situation-based test input generation. In addition, the automation of the test oracle would need a heuristic approach when testing complex GUIs to overcome their characteristics of unpredictable test outcomes. This would tend toward an oracle that would find suspicious deviations and would need to define some new qualitative measurements. The input into this element is the flow sheet of the process system and the output is a file in XML format which contains essential information about the process system design. It’s a wrapper around tkinter that presents the programmer with a very Python-like interface. Among the above-mentioned tools, Tkinter is the easiest tool to develop GUI based interfaces. Tkinter is very well documented as you mentioned, but rather limited, as Tk is, so it’s fine for very simple interfaces but not much more.

In the process, the concept of a handle in MATLAB is introduced as a way to interact with different components of the GUI. sueñ They also give customers an impression of a shoddy, unprofessional product, especially when a GUI has many of them.

wxPython is much more capable is and is pretty good, but is rather poorly documented, so you just have to find your way with it. Formerly known as PyGTK, thePython GTK+ 3project provides Python bindings to GTK objects . GTK+ is most famously used as the foundation for the GNOME desktop, but it’s available for stand-alone applications on Linux, Windows, and Mac. With Python GTK+ 3, the same framework is available for your Python projects. This opens up the possibility of developing applications in Python which have a familiar look and feel across many platforms, while taking advantage of the tools and knowledge of the large Qt community.

Fortunately, they are fairly easy for usability experts to spot. Finally, they are usually easy to correct unless they are due to limitations of the GUI tools used to build the software. This chapter describes the most common GUI control bloopers, with design rules for avoiding them. MBT tends to generate a large amount of test cases which will become impractical even if executed automatically for future GUIs. On the contrary side testing needs to withstand the coverage of the exponential growth of GUIs comprising more and more features. Thus, testing GUIs will require even more emphasis to optimize and minimize test suites in the future. The goal is to find coverage of GUI interactions and events by test instances of test inputs and test sequences with high defect detection likelihood.
