swt表对单元格中的文本长度有限制吗?

本文介绍了swt表对单元格中的文本长度有限制吗?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用JFace TableViewer和数据绑定来显示数据库表的数据，有些列的文本很长，我发现文本被切掉了.如果我激活与该单元格关联的文本编辑器，则可以看到全文.

I use JFace TableViewer and databinding to display data of a database table, some columns have very long text, I found the text is cut out. if I activate the text editor associated with that cell, I can see the full text.

swt表对单元格中的文本长度有限制吗?还是操作系统有这样的限制?(我正在使用eclipse 3.6和Windows 7 32位)

Does swt table has limitation on text length in a cell ? or the OS has such limitation ?(I am using eclipse 3.6 and windows 7 32 bit)

推荐答案

这是Windows bug/功能(有关详细信息，请参见bugzilla )，这是证明(代码的Linux屏幕截图)

It's windows bug/feature (see bugzilla for details), here is the proof (linux screenshot of your code)

我可能可以通过自我单元格渲染来解决此错误/功能(请参见自定义工程图表格和树项教程.

I may be possible to workaround this bug/feature by self cell rendering (see Custom Drawing Table and Tree Items tutorial).
