选择下一个单元格 JTable

发布于 2024-08-04 17:17:51 字数 104 浏览 5 评论 0原文

我想制作一个 jTable,其中当用户选择不可编辑的单元格时,它应该自动将焦点更改到下一个可编辑的单元格。重要提示:用户可以通过键盘(选项卡或箭头)和鼠标单击来选择单元格。是否可以??怎么去呢?

I would like to make a jTable in which when user select an uneditable cell then it should change focus to the next editable cell automatically. Important: the user could select a cell by keyboard (tab or arrow) and by mouse clicking. Is it possible?? How to to it?

此链接详细介绍了以编程方式在 JTable 组件中进行选择;你必须将鼠标监听器/等链接起来才能解决这个问题。

This link details Programmatically Making Selections in a JTable Component; you'd have to have mouselisteners/etc chained to work off this.

表格选项卡展示了如何使用键盘进行操作。

我从未尝试过,但当您单击单元格时,您应该能够使用 MouseListener 来调用相同的操作。

刚刚对 MouseListener 进行了快速测试,它似乎工作正常:

JTable table = new JTable(...);
final EditableCellFocusAction action = 
    new EditableCellFocusAction(table, KeyStroke.getKeyStroke("TAB"));

MouseListener ml = new MouseAdapter()
{
    public void mouseReleased(MouseEvent e)
    {
        JTable table = (JTable)e.getSource();
        int row = table.rowAtPoint(e.getPoint());
        int column = table.columnAtPoint(e.getPoint());

        if (! table.isCellEditable(row, column))
        {
                ActionEvent event = new ActionEvent(
                    table,
                    ActionEvent.ACTION_PERFORMED,
                    "");
                action.actionPerformed(event);
        }
    }
};
table.addMouseListener(ml);

Table Tabbing shows how you can do it with the keyboard.

I've never tried it but you should be able to use a MouseListener to invoke the same Action when you click on a cell.

Just did a quick test for the MouseListener and it seems to work fine:

JTable table = new JTable(...);
final EditableCellFocusAction action = 
    new EditableCellFocusAction(table, KeyStroke.getKeyStroke("TAB"));

MouseListener ml = new MouseAdapter()
{
    public void mouseReleased(MouseEvent e)
    {
        JTable table = (JTable)e.getSource();
        int row = table.rowAtPoint(e.getPoint());
        int column = table.columnAtPoint(e.getPoint());

        if (! table.isCellEditable(row, column))
        {
                ActionEvent event = new ActionEvent(
                    table,
                    ActionEvent.ACTION_PERFORMED,
                    "");
                action.actionPerformed(event);
        }
    }
};
table.addMouseListener(ml);
