我知道如何在单元格编辑时选择全部,通过用SwingUtilities.invokeLater(参见elsewhere)中的所有选项替换单元格编辑器,但会导致打字行为中断.当我这样做并开始输入单元格时,首先将类型化的字符附加到字符串,然后选择它(但是选择是不可见的！),并且当输入另一个字符时,内容被替换.

当输入突出显示(但不是编辑)单元格时,是否有方法立即替换内容,但是在单击单元格时全选？

这是CellEditor使用的代码：

public class TextFieldCellEditor extends JTextField implements TableCellEditor
{
    private CellEditorListener  cellEditorListener  = null;

    private boolean             isInteger           = false;
    private Object              oldValue;

    // Start editing
    @Override
    public Component getTableCellEditorComponent(JTable table,Object obj,boolean isSelected,int row,int column)
    {
        Color color2 = DefaultLookup.getColor(this,ui,"Table.alternateRowColor");
        super.setBackground(color2 != null && (row & 1) == 1? color2 : table.getBackground());
        super.setForeground(table.getForeground());
        super.setBorder(DefaultLookup.getBorder(this,"Table.focusCellHighlightBorder"));

        super.setText(obj.toString());

        isInteger = obj instanceof Integer;
        if (isInteger)
        {
            super.setHorizontalAlignment(SwingConstants.RIGHT);
            oldValue = obj;
        }

        // SwingUtilities.invokeLater(new Runnable()
        // {
        // public void run()
        // {
        // TextFieldCellEditor.this.selectAll();
        // }
        // });

        return this;
    }

    // Retrieve e dited value
    @Override
    public Object getCellEditorValue()
    {
        if (isInteger)
        {
            // Try to convert to integer. If input is invalid,revert.
            try
            {
                return new Integer(super.getText());
            }
            catch (NumberFormatException e)
            {
                return oldValue;
            }
        }
        return super.getText();
    }

    @Override
    public boolean isCellEditable(EventObject e)
    {
        return true;
    }

    @Override
    public boolean shouldSelectCell(EventObject e)
    {
        return true;
    }

    @Override
    public boolean stopCellEditing()
    {
        cellEditorListener.editingStopped(new ChangeEvent(this));
        return true;
    }

    @Override
    public void cancelCellEditing()
    {
        cellEditorListener.editingCanceled(new ChangeEvent(this));
    }

    @Override
    public void addCellEditorListener(CellEditorListener celleditorlistener)
    {
        cellEditorListener = celleditorlistener;
    }

    @Override
    public void removeCellEditorListener(CellEditorListener celleditorlistener)
    {
        if (cellEditorListener == cellEditorListener) cellEditorListener = null;
    }
}
