What Is A Graphical User Interface


To this end, the Task Force decided to add two new classes—IntField and DoubleField—to simplify the development of applications that require numeric input. Each of these classes extends JTextField but provides additional methods to hide the complexity involved in numeric conversion and exception handling. The most useful methods available for DoubleField appear in Figure 4-4; the methods for IntField are the same except for the expected changes in the argument and result types. The interactors that you can place in the border regions are by no means limited to the JButton class used in the preceding examples. The javax.swing package includes a variety of useful interactor classes including JCheckBox, JComboBox, JLabel, JScrollBar, JRadioButton, JSlider, JSpinner, JToggleButton, JTextField.

The Start button starts the simulation, the Step button advances it a single step, the Stop button stops it, and the Reset button creates a new initial state. One of the most common uses of interactors in the border region is to control the state of an animation running in the primary window. The Java Task Force packages provides excellent support software transportes for this type of animation control through the Animator class in the acm.util package. At one level, the Animator class is simply an extension of Thread, so you can use it as the thread of control for an animation as described in section 3.1. The Animator class, however, exports several methods that are useful for writing simple animation code.

Create Apps With Graphical User Interfaces In Matlab

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. 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. 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. We introduced some of the important concepts of GUI programming in Java and also saw an overview of the GUI frameworks supported by Java. As shown above, a Panel container is embedded in a Frame window container.

How To Create A Gui Application With Python

Apps can also be packaged for installation into the MATLAB Apps tab. To share with non-MATLAB users, you can compile your apps into standalone desktop apps using MATLAB Compiler. App Designer apps can also be packaged for installation into the MATLAB Apps tab. To share with non-MATLAB users, you can compile apps into standalone desktop and web apps using MATLAB Compiler. Use the Live Editor to convert a script into a simple app that has interactive controls allowing others to experiment with variables in your code. Add sliders, dropdowns, edit fields, and buttons without writing any code. Specify what parts of the script will run when a value is changed.

None of these interactors are particularly hard to use, and the Java Task Force did not feel there was any need to extend the set of interactors except in one respect. Unfortunately, none of the existing classes is suitable for reading numeric data from the user. Note that the actions linked to the buttons are defined as methods of the widgets.

Then we can apply any layout manager to the panel that will organize the components or elements inside the panel. All the GUI components including frames have some common properties as they are a part of a common inheritance hierarchy shown above. So we can say that there is a powerful case of code sharing in the Java Swing package. Apart from these, it also contains classes related to Java 3D, Java 2D, Java Accessibility, etc. JFC is in sync with Java’s object and components model and thus is easy to use. We have also discussed the concept of multithreading and exceptions.

  • Graphical user interface , a computer program that enables a person to communicate with a computer through the use of symbols, visual metaphors, and pointing devices.
  • The GUI is now the standard computer interface, and its components have themselves become unmistakable cultural artifacts.
  • It was even argued that, with the advent of the GUI, engineering had merged with art to create a new medium of the interface.

Using all these concepts, we can develop high-level applications in Java that are reusable and robust as well as self-contained. indicates a table with seven columns and as many rows as needed to display the components in the table. That layout will form the basis for a calendar application in section 4.6. For the last several years, the Computer Science Advanced Placement course has used a marine biology simulation as its case study. In that simulation, different species of fish inhabit an environment and evolve by breeding, moving, and dying as specified by various parameters of the simulation. A sample run of the applet version of the Marine Biology Simulation appears in Figure 4-6, which shows both the random initial state of a simulation and a control panel at the bottom of the window.
