To set a corner component, you can use the setCorner(String key,
Component corner) method. The legal values for the key are:
JScrollPane.LOWER_LEFT_CORNER
JScrollPane.LOWER_RIGHT_CORNER
JScrollPane.UPPER_LEFT_CORNER
JScrollPane.UPPER_RIGHT_CORNER
Listing 37.6 shows an example that displays a map in a label and
places the label in a scroll pane so that a large map can be scrolled.
The program lets you choose a map from a combo box and display it in
the scroll pane, as shown in Figure 37.12.
Figure 37.12
The scroll pane can be used to scroll contents automatically.
