JTable 转到行

发布于 2024-10-10 18:15:07 字数 519 浏览 1 评论 0原文

我正在尝试实现 goto 函数。我有一个包含几千行的 JTable，我希望能够跳转到指定的行号。

else if (BUTTON_GOTO.equals(command))
{
    int gotoLine = Integer.valueOf(gotoField.getText());            
    logTable.setRowSelectionInterval(gotoLine, gotoLine);
}

上面的代码将突出显示我正在查找的行，但不会跳转到它。有谁知道该怎么做？

谢谢

编辑使用下面的解决方案时存在一个错误，应用程序会跳转到比所需行短的几行。有关更多详细信息，请参阅以下主题：

原文

I am trying to implement a goto function. I have a JTable that has a few thousand rows and I want to be able to jump to a specified row number.

else if (BUTTON_GOTO.equals(command))
{
    int gotoLine = Integer.valueOf(gotoField.getText());            
    logTable.setRowSelectionInterval(gotoLine, gotoLine);
}

The code above will highlight the row I am looking for, but does not jump to it. Does anyone know how to do this?

Thanks

EDIT
There is a bug using the solution below where the application jumps a few lines short of the desired line. See the topic below for further details:

尝试：

logTable.scrollRectToVisible(logTable.getCellRect(gotoLine, 0, true));

getCellRect() 返回一个将单元格限制在给定行和列的 矩形，并且 scrollRectToVisible() 告诉表的父级（如果您使用的是 JScrollPane，则应该是 JViewPort ) 滚动到那里。

Try:

logTable.scrollRectToVisible(logTable.getCellRect(gotoLine, 0, true));

getCellRect() returns a Rectangle which bounds the cell at the given row and column, and scrollRectToVisible() tells the table's parent (which should be a JViewPort if you are using a JScrollPane) to scroll there.

我有一个类似的问题，我在上面的帮助下解决了
首先我添加了 gotoButton 和文本字段

    JPanel gotoPanel = new JPanel();
    JButton gotoRowButton = new JButton("Goto Address");
    JTextField gotoAddressTextField = new JTextField();
    gotoAddressTextField.setColumns(12);
    gotoPanel.add(gotoRowButton);
    gotoPanel.add(gotoAddressTextField);

    frame.add(gotoPanel, BorderLayout.NORTH);

，然后我为 gotoRowButton 添加了一个 actionListnener

        gotoRowButton.addActionListener(new ActionListener() {
           public void actionPerformed(ActionEvent e) {
            
             table.setRowSelectionInterval(
                 Integer.parseInt(gotoAddressTextField.getText(), 
                 Integer.parseInt(gotoAddressTextField.getText()));
            table.scrollRectToVisible(
            table.getCellRect(
              Integer.parseInt(gotoAddressTextField.getText()), 1, true)
      );
        }
    });

这是我工作的视觉效果

I have had a similar issue which i solved with help of above
first I added gotoButton and text field

    JPanel gotoPanel = new JPanel();
    JButton gotoRowButton = new JButton("Goto Address");
    JTextField gotoAddressTextField = new JTextField();
    gotoAddressTextField.setColumns(12);
    gotoPanel.add(gotoRowButton);
    gotoPanel.add(gotoAddressTextField);

    frame.add(gotoPanel, BorderLayout.NORTH);

then I added an actionListnener for the gotoRowButton

        gotoRowButton.addActionListener(new ActionListener() {
           public void actionPerformed(ActionEvent e) {
            
             table.setRowSelectionInterval(
                 Integer.parseInt(gotoAddressTextField.getText(), 
                 Integer.parseInt(gotoAddressTextField.getText()));
            table.scrollRectToVisible(
            table.getCellRect(
              Integer.parseInt(gotoAddressTextField.getText()), 1, true)
      );
        }
    });
