@Override
public void mouseClicked(MouseEvent e) {
JTree tree = (JTree) e.getSource();
Point p = e.getPoint();
int row = tree.getRowForLocation(e.getX(), e.getY());

示例4: mouseClicked
import javax.swing.JTree; //导入方法依赖的package包/类
public void mouseClicked(MouseEvent e) {

// click - click should be possible only on the check box area
// and double click should be bordered by title text.
// we need a test how to detect where the mouse pointer is

Point p = e.getPoint();
int x = e.getX();
int y = e.getY();
int row = tree.getRowForLocation(x, y);

}
