This example demonstrates how to display labels (numerical values) at the major ticks (see e797 显示JSlider的标记).

    // Create a horizontal slider that moves left-to-right

    JSlider slider = new JSlider();

    // Set major tick marks every 25 units

    int tickSpacing = 25;

    slider.setMajorTickSpacing(tickSpacing);

    // Determine if currently painting labels

    boolean b = slider.getPaintLabels(); // false

    // Paint labels at the major ticks - 0, 25, 50, 75, and 100

    slider.setPaintLabels(true);

The slider allows you to use an arbitrary label at any particular major tick mark. This example configures a slider that shows an icon at the minimum and maximum positions. The component is only used to render the label and so it can be used at more than one position. Unfortunately, it also means that if the component is interactive (e.g., a button), it will not respond to mouse and keyboard gestures.

    // Retrieve current table

    java.util.Dictionary table = slider.getLabelTable();

    // Create icon

    ImageIcon icon = new ImageIcon("icon.gif");

    JLabel label = new JLabel(icon);

    // Set at desired positions

    table.put(new Integer(slider.getMinimum()), label);

    table.put(new Integer(slider.getMaximum()), label);

    // Force the slider to use the new labels

    slider.setLabelTable(table);
