Spinners

You might be wondering just what a spinner is. It’s a new 1.4 component similar to the JComboBox, but it shows only one item. It includes up and down arrows to "scroll” through its set of values. A JFormattedTextField is used to edit and render those values. Spinners are quite flexible. They work nicely with a set of choices (such as the months of the year) as well as with unbounded ranges such as a set of integers. Figure 7-13 shows several examples of spinners in different L&Fs. The Mac L&F is missing from this figure because the SDK 1.4 was not available on OS X at the time we went to press.

The classes involved in spinners are shown in Figure 7-14.

Properties

JSpinner has several properties related to the values it displays (see Table 7-16). Most of the properties are easy to understand from their names alone. The currently selected value is available through the read/write value property.
