Question

We would like to know how to layout JList items with horizontal wrap.

Answer

import java.awt.Dimension;
//w  w  w  .jav  a2s .c  o m
import javax.swing.DefaultListModel;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JScrollPane;
import javax.swing.ListSelectionModel;

public class Main {

  public static void main(String[] args) {
    DefaultListModel<String> model = new DefaultListModel<>();
    JList<String> sList = new JList<>(model);
    for (int i = 0; i < 100; i++) {
      model.addElement("String " + i);
    }

    sList.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
    sList.setVisibleRowCount(-1);
    sList.setLayoutOrientation(JList.HORIZONTAL_WRAP);

    JFrame frame = new JFrame("Foo001");
    frame.getContentPane().add(new JScrollPane(sList));
    frame.getContentPane().setPreferredSize(new Dimension(400, 300));
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.pack();
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);
  }
}
