The JList Class

The JList class is the generic Swing implementation of a list component. In the default selection mode, you can make multiple selections by clicking with the mouse while holding down the modifier key defined by the current L&F (generally Shift for a single, contiguous range and Ctrl or Command for noncontiguous selections). The JList class does not provide scrolling capabilities, but it can be set as the viewport of a JScrollPane to support scrolling. Figure 7-8 shows the JList component in four different L&Fs.

Properties

The JList class essentially combines the features of the data model, the selection model, and the cell renderer into a single Swing component. The properties of the JList class are shown in Table 7-9.
