为JTable添加单元格工具提示
覆盖JTable的getToolTipText(MouseEvent e)方法
@Override
public String getToolTipText(MouseEvent e) {
int col = columnAtPoint(e.getPoint());
if (col != 0) {
return null;
}
int row = rowAtPoint(e.getPoint());
String toolTip = null;
if (row > -1 && col > -1) {
Object value = getValueAt(row, col);
if (value != null && !value.toString().isEmpty())
toolTip = value.toString();
}
return toolTip;
}
