java - 删除 Jtable 中的行后出错

Question

我有一个框架，其中包含一个表格和两个按钮。

1) 重复行2) 删除行

表格第三列的组合

我有一个场景，我复制空白行并单击最后一行的组合框以选择该行，然后单击删除行按钮...然后在删除之后，每当我尝试单击任何单元格时，它都会给我以下错误。

Answer 1

当您单击按钮时，编辑器仍然处于 Activity 状态。您需要在删除行之前停止编辑。

您可以将以下内容添加到您的 ActionListener 中:

if (TblFilePane1.isEditing())
    TblFilePane1.getCellEditor().stopCellEditing();

您应该将它添加到两个监听器。或者您可能想查看 Table Stop Editing对于可以在表格上设置的属性，当表格失去焦点时停止编辑。

此外，变量名不应以大写字符开头。学习并关注 Java Conventions .
