Swing layout Managers

Swing Layout Managers in Java Java basics notes Java Fundamental notes The AI Revolution MALAYALAM ARTICLE Swing layout manager. The layout manager automatically positions all the components within the container. Layout refers to the arrangement of components within the container. Layout is placing the components at a particular position within the container. The task of laying out the controls is done automatically by the layout manager. Even if you do not use the layout manager, the components are still positioned by the default layout manager. It is possible to lay out the controls by hand, however, it becomes complicated. Java provides various layout managers to position the controls. Properties like size, shape, and arrangement vary from one layout manager to another. There are the following classes that represent the layout managers: java.awt.BorderLayout java.awt.FlowLayout java.awt.GridLayout java.awt.CardLayout java.awt.GridBagLayout javax.swing.GroupLayout javax.swing....

Component and containers

Component and containers Component A component is an independent visual control, such as a push button or slider. A component is an object with a graphical representation that can be displayed on the screen and interact with the user. Examples of components include buttons, checkboxes, and scrollbars commonly found in graphical user interfaces. Swing components inherit from the javax.Swing.JComponent class, which is the root of the swing component hierarchy. Swing components are derived from the JComponent class. JComponent provides the functionality that is common to all components. For example, JComponent supports the pluggable look and feel. JComponent inherits the AWT classes Container and component. Thus, a swing component is built on and compatible with an AWT component. All of the swing's components are represented by classes defined within the package javax.swing. The following table shows the class names for swing components JApplet JColorChooser JDialo...

Model View Controller-Hierarchy of Swing Classes

Model view controller(MVC) The Hierarchy of Swing Classes Model view controller(MVC) Swing mainly follows the Model view controller( MVC ) architecture. Using the Model view controller, we can make changes in one component without impacting or touching other components. It is also known as loosely coupled architecture. The Model-View-Controller is a well-known software architectural pattern ideal for implementing user interfaces on computers by dividing an application into three interconnected parts. Swing uses the Model-View-Controller Architecture( MVC ) as the fundamental design behind each of its components. Essentially, MVC breaks GUI components into three elements. Each of these elements plays a crucial role in how the component behaves. The main goal of MVC is to separate internal representations of an application from the ways information is presented to the user. Initially, MVC was designed for desktop GUI applications but it’s quickly become an ...
