示例1: adjustmentValueChanged
import javax.swing.JScrollBar; //導入方法依賴的package包/類
/**
* Listens to changes of the scroll bar of the text are showing the EULA text, enables the check
* box once the user scrolled to the end of the document.
*/
@Override
public void adjustmentValueChanged(AdjustmentEvent e) {
JScrollBar scrollBar = this.scrollPane.getVerticalScrollBar();
if (e.getSource() == scrollBar) {
// the maximum value of the scroll bar assumes that the content is
// not visible anymore, since this is not the case when scrolling
// to the end of the document (the last part is still visible),
// we have to include the visible amount in the comparison

if (currentValue >= scrollBar.getMaximum()) {
// the user scrolled to the end of the document
this.acceptCheckBox.setEnabled(true);
this.acceptCheckBox.requestFocusInWindow();
}
