It is one of Java’s libraries to implement GUI (graphical user interface). By using Swing applications are highly interactive and flexible regarding features. We can check that in the JetBrains application IntelliJ IDEA. In the community version, we can find below:
2. How events works?
Swing beyond events is based on action listeners from the AWT and Swing is newer version of AWT library. An „event handling” mechanism is worth paying attention to because it is responsible for managing events.This mechanism recognises and decides what should happen when a specific event occurs. Please see a code example to understand it better.
When we press a specific keyboard key the code above calls a key event. Numbers: 38, 37, 39, and 40 are accordingly for: up, left, right and down arrows. Additionally, we can see on the terminal which key was pressed. Please see the below image:
Also, I prepared an example of an event called pressing the computer mouse. Please see below:
3. Sum up
On the one hand, „window applications” are highly interactive and flexible for users because of the Swing library. For example, it can be IntelliJ IDEA, which has plenty of features that help in the nowadays programming.
On the other hand, Swing is not as popular as other front-end frameworks such as React or Angular. Nevertheless, it is worth knowing Swing and events, and how they work together. It helps us to understand better more advanced matters.
