JTable中的单元验证 [英] Cell validation in JTable

问题描述

我有一个JTable需要对用户可以输入文本的单元格进行单元验证。当用户输入无效文本时，单元格的边框变为红色。

I have a JTable that needs cell validation for the cells where the user can input text. When a user enters invalid text the border of the cell turns red.

我设法让这个工作关联一个二维数组，以标记每个单元格是否有错误或不是。

I've managed to get this working associating a two dimension array to flag if each cell has errors or not.

问题是用户必须能够重新排序表（按列）。我必须将错误标志存储在表模型中，而不是分开存储。任何人都有想法如何做到这一点？

The problem is that the user must be able to reorder the table (by column). I have to store the error flag in the table model, not separatly. Anyone has ideas how to do this?

推荐答案

还要考虑自定义 TableCellEditor ，见此处及以下。添加 InputVerifier ，如此处所示，是一个不错的选择。

Also consider a custom TableCellEditor, seen here and below. Adding an InputVerifier, as shown here, is a good alternative.

由于用户必须能够按列对表格重新排序：

As the user must be able to reorder the table by column:

JTable 提供从模型坐标转换为视图坐标的方法 - convertColumnIndexToView 和 convertRowIndexToView - 并且从视图坐标转换为模型坐标 - convertColumnIndexToModel 和 convertRowIndexToModel 。

JTable provides methods that convert from model coordinates to view coordinates — convertColumnIndexToView and convertRowIndexToView — and that convert from view coordinates to model coordinates — convertColumnIndexToModel and convertRowIndexToModel.
