Add a Jlist to a JScrollPane

Question

I have a JList that I need to Place inside a scroll Pane because I am getting the JList from the database and the values can increase greatly. I need to be able to scroll th

Answer 1

As mentioned, the list is already added to JScrollPane, hence need not be added again. Also, for scroll to work, it needs to define the list method setVisibleRowCount(int). I have modified the code above in CheckBoxListener method to make it work.

Checkboxlistener() 
{   
    setSize(1300, 600);

    String labels[] = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J"};
    checkBoxesJList = new JList(labels);
    checkBoxesJList.setBounds(10, 30, 80, 600);
    checkBoxesJList.setBackground(Color.LIGHT_GRAY);
    checkBoxesJList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

    checkBoxesJList.setVisibleRowCount(5);

    JScrollPane scrollPane = new JScrollPane(checkBoxesJList);  

    jpAcc.add(scrollPane);

    add(jpAcc);

    setVisible(true);

}
