JasperReports:防止textField在空格或连字符上拆分 [英] JasperReports: Prevent textField to split on space or hyphen

问题描述

我有一个JasperReports模板，其中包含一个textField元素，该元素将包含可变长度的字符串.如果字符串太长而无法适合宽度，则将其拆分，除非字符串包含连字符或空格字符，否则可以进行拆分.在这种情况下，字符串将从该char拆分.以下是一些输入，观察到的结果以及想要的结果和摘要的示例，使我的观点更容易理解.

I have a JasperReports template that contains a textField element that will contain a variable length of strings. If the string is too long to fit the width, it'll be split which is fine except when the string contains a hyphen or a space char. In this case the string is split from that char. Below are some example of what's the input, observed outcome and wanted outcome + summary to make my point easier to understand.

input      observed   wanted   summary
_____________________________________
overflow  -> overfl -> overfl : OK
over flow -> over   -> over f : NOT OK
over-flow -> over-  -> over-f : NOT OK

将reportElement设置为具有isStretchWithOverflow ="true"属性会将文本分为两行，但这不是我们想要的行为.

Setting the reportElement to have isStretchWithOverflow="true" attribute will split the text on two lines, but this is not wanted behaviour.

反正有解决此问题的方法吗?

Is there anyway to fix this?

谢谢.

编辑:输入数据来自外部来源，因此我无法直接更改它.我进行了一些测试，发现使用不间断的空格将对空格有效.另一方面，不打断连字符根本不会打印，即文本"over-flow"变成"overflow".不太想要什么.

EDIT: The input data comes from an external source, so I cannot directly change that. I ran some tests and noticed that using non-breaking space will do for spaces. non-breaking hyphen on the other hand is not printed at all, i.e. text 'over-flow' becomes 'overflow'. Not quite what is wanted.

尽管输入源不在我的控制范围内，但我可以编写一个Scriptlet来解决此问题，该脚本必须将空格改为不间断的连字符，并将连字符改为不间断的连字符，只有打印出那些令人讨厌的连字符为止

Despite the input source not in my control, I could fix this problem by writing a Scriptlet that'll change spaces to non-breaking spaces and hyphens to non-breaking hyphens, only if those darn non-breaking hyphens would be printed.

通过打印为PDF的方式，以防出现问题.

Printing to PDF by the way, in case that gives some hints of the problem.

推荐答案

这是字体问题.如果字体支持连字符，连字符也可以正常工作(\ u2011).有关如何加载默认字体(例如，DejaVu Sans)的信息，请参见字体示例.

It's a font issue. Non-breaking hyphen works(\u2011) fine, when the font supports it. See fonts sample on how load other than the default font (DejaVu Sans for example).

如果有人比Scriptlet拥有更好的输入源修改选项，请告诉我.

If anyone has a better option for the input source modification than the Scriptlet, please let me know.
