Usage

From source file:Main.java

public static void main(final String args[]) {
    String labels[] = { "A", "B", "C", "D", "E" };
    JFrame frame = new JFrame("Sizing Samples");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JList jlist1 = new JList();
    jlist1.setListData(labels);//from www  .j a  v  a2s  .  c  o m

    jlist1.setVisibleRowCount(4);
    JScrollPane scrollPane1 = new JScrollPane(jlist1);
    frame.add(scrollPane1, BorderLayout.NORTH);

    Rectangle r = jlist1.getCellBounds(0, 1);

    frame.setSize(300, 350);
    frame.setVisible(true);
