java-以编程方式启用在按键时编辑JTable单元格

我想启用编辑键F2上的JTable单元的功能.

我知道默认情况下双击将启用编辑,但是有没有办法将该事件绑定到键？我尝试了此链接JTable edit on keypress,但对我不起作用.

这是我的代码：

public class DatabaseJTable extends JTable implements MouseListener {
    public DatabaseJTable(Object [][] data, Object [] columnNames) {
        super(data, columnNames);
        InputMap inputMap = this.getInputMap(JComponent.WHEN_FOCUSED);
        ActionMap actionMap = this.getActionMap();
        this.addMouseListener(this);

    // bind edit record to F2 key
        inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_F2, 0), "edit");
        actionMap.put("edit", new AbstractAction() {
            @Override
            public void actionPerformed(ActionEvent ae) {
                // TODO Auto-generated method stub
                DatabaseJTable table = (DatabaseJTable)ae.getSource();
                table.changeSelection(table.getSelectedRow(), 1, false, false);
                table.editCellAt(table.getSelectedRow(), 1);
                System.out.println("F2 pressed");
            }
        });
    // binding delete record to Delete key
        inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_DELETE, 0), "delete");
        actionMap.put("delete", new AbstractAction() {
            @Override
            public void actionPerformed(ActionEvent ae) {
                // TODO Auto-generated method stub

            }
        });
    }

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

提前致谢.

解决方法:

F2已经是JTable用来开始编辑的默认KeyStroke.

有关所有组件使用的所有按键的表格,请参见Key Bindings.您还将找到使用键绑定的示例.

如果您确实创建了自己的操作,则应使用类似以下代码的方法：

int row = table.getSelectedRow();
int column = table.getSelectedColumn();

if (editCellAt(row, column))
{
    Component editor = table.getEditorComponent();
    editor.requestFocusInWindow();
}

因此,一旦按下该键,编辑器就会获得焦点.

显然,Aqua LAF不会绑定F2,因此您似乎需要自己执行此操作.假设在ActionMap中定义了“ startEditing”操作,则可以使用：

KeyStroke keyStroke = KeyStroke.getKeyStroke("F2");
InputMap im = table.getInputMap(JTable.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
im.put(keystroke, "startEditing");
