java - Swing:在Jtable中，当光标向下移动时，JScroll条也应该向下移动吗？

Question

当用户双击该行时，我正在使用 JTable，然后鼠标应该聚焦在下一行。 -> 好的在滚动条的时候如何将Jscrollbar & 鼠标同时移动

public void TableMouseListener implements MouseListener {


public void mouseClicked(MouseEvent e) {

            //if the double click is performed or left button
  if (SwingUtilities.isLeftMouseButton(e) && e.getClickCount() >= 2) {

    Robot r;
    Point p = e.getPoint();
    JTable table = (JTable) e.getSource();
    int rowNumber = table.rowAtPoint(p);
    PointerInfo a1 = MouseInfo.getPointerInfo();
    Point b1 = a1.getLocation();
    int x1 = (int) b1.getX();
    int y1 = (int) b1.getY();
    System.out.println(x1+" :X :  "+x1);
    System.out.println(y1+" : Y : "+y1);

    //Mouse move to next record based row height                
    r = new Robot();
    r.mouseMove(x1, y1 +table.getRowHeight());

    //Can any one suggest move the scrollbar based on the cursor move
    //Rectangle rect = viewport.getViewRect();
    //rect.y = rect.y + table.getRowHeight();
    //viewport.scrollRectToVisible(rect); -> IF scrollbar is used to move but not in next poistion
    } catch (Exception e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}




                }
            }
        }

Answer 1

• 适当设置 ListSelectionModel到 JTable

• 添加 ListSelectionListener而不是使用 AWT.Robot，必须测试是否选择了任何行 (.... >-1)，

• 必须测试JTables View 中的1st. 或last 行，

• 更改选择 table.setRowSelectionInterval(int index0, int index1)
