java - JTable Cell 中的 JDatechooser

Question

我想在 JTable 单元中添加一个 JDateChooser。我知道如何添加文本框、组合框和复选框。

我允许用户向表中输入数据。用户应该能够为每一行选择一个日期。

任何帮助，将不胜感激。
谢谢

Answer 1

阅读 Swing 教程中关于使用其他编辑器的部分。

它展示了如何使用 JColorChooser 创建自定义编辑器。我猜想代码与使用 JDateChooser 类似。

Answer 2

如下设置 CellEditor：

table.getColumnModel().getColumn(1).setCellEditor(new JDateChooserEditor(new JCheckBox()));

/************************************************* ************************/

这是 JDateChooserEditor 的代码：

class JDateChooserEditor extends DefaultCellEditor
{
  public JDateChooserEditor(JCheckBox checkBox)
  {
    super(checkBox);

  }

  JDateChooser date;
  public Component getTableCellEditorComponent(JTable table, Object value,
      boolean isSelected, int row, int column) 
  {

         date = new JDateChooser();
         date.setDateFormatString("dd-MM-yyyy");
         return date;
  }

  public Object getCellEditorValue() 
  {
    return new String(((JTextField)date.getDateEditor().getUiComponent()).getText());
  }

  public boolean stopCellEditing()
  {
    return super.stopCellEditing();
  }

  protected void fireEditingStopped() {
    super.fireEditingStopped();
  }
}
