如何使jtable在java中不可编辑?

I created a function which loads data into a JTable. Everything's working fine except that all the cells in this table are editable. Btw, I used defaultTableModel for the table model. Im doing this in Netbeans IDE. Please help. Here's my code:

我创建了一个将数据加载到JTable的函数。除了该表中的所有单元格都是可编辑的之外，其他一切都运行良好。顺便说一下，我使用defaultTableModel作为表模型。我在Netbeans IDE中这样做。请帮助。这是我的代码:

private void updateTable(String searchText){

    if(searchText != null)
        this._sqlCmd = this._sqlCmd + " WHERE "+columnCombo.getSelectedItem()+" LIKE '%"+searchText+"%'";
    jTable1.setSurrendersFocusOnKeystroke(true);
    table = (javax.swing.table.DefaultTableModel) jTable1.getModel();  

    try{
        table.setRowCount(0);
    }catch(Exception e){}

    try {
        ResultSet rs = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY).executeQuery(_sqlCmd);
        while (rs.next()){
            Object[] data = new Object[numOfCols];
            for(int i=0; i<data.length; i++){
                data[i] = rs.getObject(i+1);
            }
            table.addRow(data);
        }
        table.fireTableDataChanged();


    } catch (SQLException ex) {
        Logger.getLogger(FindContactGrid.class.getName()).log(Level.SEVERE, null, ex);
    } 
}

5 个解决方案

#1

 private TableModel model = new DefaultTableModel(data, columnNames)
  {
    public boolean isCellEditable(int row, int column)
    {
      return false;//This causes all cells to be not editable
    }
  };
  private JTable table = new JTable(model);

Edited. If you are doing this in Netbeans IDE designer, follow the steps below:

编辑。如果您正在Netbeans IDE designer中进行此操作，请遵循以下步骤:

• Select the form on which the JTable is placed
• 选择放置JTable的表单
• From the Navigation Pane, expand JScrollPane and right-click on JTable and Select Customize Code as shown below:
• 从导航窗格中展开JScrollPane，右键单击JTable，选择Customize代码，如下所示:

• On the code customizer, select the second drop down and choose custom property. This enables you to edit the DefaultTableModel code definition.
• 在代码定制器上，选择第二个下拉并选择custom属性。这使您能够编辑DefaultTableModel代码定义。
• Now paste this: {public boolean isCellEditable(int row, int column){return false;}} before the last closing blacket );
• 现在粘贴这个:{公共布尔型isCellEditable(int row, int列){返回false;}}在最后关闭blacket之前;

Your final setup should look as shown below:

最后的设置应该如下所示:

• Press ok to save - and job done.
• 按ok保存-完成任务。

If you use DefaultTableModel you can override the method isCellEditable and implement it when constructing GUI:

如果您使用DefaultTableModel，您可以重写方法isCellEditable，并在构建GUI时实现它:

table.setModel(new DefaultTableModel() {

    @Override
    public boolean isCellEditable(int row, int column) {
       return false;
    }
});

#3

Using Netbeans ANOTHER WAY is possible. if you want to continue using the default table model as the OP mentions It's not necessary to create a new table model if you don't want to.

使用Netbeans也有可能。如果您想继续使用默认的表模型，就像OP提到的那样，如果您不想创建一个新的表模型，那就没有必要了。

1. Select the JTable "properties"

   选择JTable“属性”

2. Select the "TableModel" field in "properties" which will open another DialogBox.

   在“属性”中选择“TableModel”字段，该字段将打开另一个对话框。

3. From there it is possible to modify the "editable" checkbox field for each column.

   从这里可以修改每个列的“可编辑”复选框字段。

Not sure from which version this starts but I'm using Netbeans 7.2

不确定从哪个版本开始，但我使用Netbeans 7.2

#4

As other said you have to create you own DefaultTableModel and override isCellEditable. In order to use it in Netbeans designer :

正如其他人所说，您必须创建自己的DefaultTableModel并覆盖isCellEditable。为了在Netbeans设计者中使用:

• Right click on your table
• 右键单击您的表
• Properties -> Code
• 属性- >代码
• In Custom Creation Code add this : new JTable(new MyModel()) (assuming you create class MyModel extends AbstractTableModel)
• 在自定义创建代码中添加以下内容:new JTable(new MyModel())(假设您创建了类MyModel，扩展了AbstractTableModel)

Try This

试试这个

JTable table = new JTable();
table.setEnabled(false);
