This article mainly introduces the Java Swing class has what the role of the relevant knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe you read this Java Swing class what the role of the article will have a harvest, let's take a look.

Overview of Swing Class Library

What we see, whether it is the browser or the use of software, they all need to have a graphical interface, which is convenient for users to use interactively. In Java, there are tools specifically for developing graphical interfaces, such as AWT and Swing.

As a new generation of graphical interface development tool, Swing is better than AWT in developing interface. Because Swing is a lightweight component, using pure Java development, it inherits the cross-platform nature of the Java language, is no longer limited to the graphical interface of the local platform, and can maintain the same running effect on more platforms. In addition, Swing provides more graphical interface components than AWT, which can be used to develop more beautiful and excellent graphical interface programs.

Swing class library structure

Swing components are designed in the way of MVC, so it realizes the separation of display logic and data logic of GUI components, which allows programmers to customize Render to change the display appearance of GUI components, thus providing more flexibility.

Swing is built primarily around JComponent components, while JComponent is extended from AWT's container.

It is not difficult to see from the figure that Swing components begin with J except for the AbstractButton class. Therefore, except that Swing container components directly inherit the container component classes in the AWT class library, most other components inherit JComponent components.

These components can be divided into two categories, container components and non-container components. Container components include JFmme and JDialog, while non-container components include JButton, JMenu, JPanel and so on.

Packages for the Swing class library

The Swing class library is made up of many packages, and it is with the classes in these packages that work together to complete the GUI design.

Of these, the javax.swing package is the largest package provided by the Swing class library, which contains nearly 100 classes and 25 interfaces. It can be said that almost all the Swing components are in this package.

Also widely used is the javax.swing.event package, which defines events and event listener classes that respond to events triggered by Swing components.

In addition, Swing's table component (JTable) is in the javax.swing package, but its supporting classes are in the javax.swing.table package. In addition to JTable, there are graphics drawing classes and editors that are all in the javax.swing.table package.

This is the end of this article on "what is the purpose of Java's Swing class?" Thank you for reading!
