How to create java swing jlist with detail examples

-Java swing JList allows you to display a list of group objects. In this article we will explore the basics of it.

Create and capture events in java swing jlist

-We are going to create a program that contains a Java swing jlist of colors. When you click a color, the background color of the JFrame will change with the color name.

File name: JListDemo.java

Continue JListDemo.java

* Java swing JList constructors:

- JList (): creates an empty JList
- JList (E [] listData): Creates a JList with an array of data
- JList (ListModel dataModel): create JList with an existing model
- JList (Vector listData): create JList with data in vertex

* How to capture an event when selecting an item in the java swing jlist?

- Add the addListSelectionListener method for JList. It then overrides the valueChanged method to accomplish the desired task. Use the getSelectedIndex method to get the selected location in JList

-Note in the example above that we use the JFrame directly, we want to change the background color of the frame we need to setLayout for the JFrame and when we change the background color we need to call getContentPane (). SetBackground.

Adding elements in java swing jlist

-The following example will add some elements in java swing JList. JFrame contains a JPanel (main panel), main panel is setLayout with BorderLayout and contains the object as shown below:

File name JListAddOrRemoveItem.java

Continue JListAddOrRemoveItem.java

Continue JListAddOrRemoveItem.java

-In this example java swing JList was initialized with a model called DefaultListModel, which is a model that Java built for us, it is very easy to use. Adding some elements to java swing jlist requires us to do it through the JList model, but not directly. (Unless you add a single list (or array) of elements and recreate the JList ). Detailed steps are clearly noted in the code, you follow in it.
