[英]JFormattedTextField using a regular expression formatter?
After much frustration with getting a JFormattedTextField to work with my custom formats, I was wondering if there was a Formatter
or FormatterFactory
that uses regular expressions? 在让JFormattedTextField与我的自定义格式一起使用后,我感到非常沮丧,我想知道是否有使用正则表达式的Formatter
或FormatterFactory
?
My idea is that if there is one, then I could wrap it in a static class and invoke it like so: 我的想法是,如果有一个,那么我可以将它包装在一个静态类中并像这样调用它:
mFormattedTextField.setFormatterFactory(
SomeStaticClass.getRegexFormatFactory("^(\\d{1,}h)(\\s([0-5])?[0-9]m)?$"));
See my previous question for more background: 有关更多背景,请参阅我之前的问题
" I want to use a JFormattedTextField to allow the user to input time duration values into a form. Sample valid values are: 2h 30m
72h 15m
6h
0h
" “我想使用JFormattedTextField来允许用户将持续时间值输入到表单中。示例有效值为: 2h 30m
72h 15m
6h
0h
”
Have you read this article ? 你读过这篇文章了吗? In case that link rots away, it says all you really need to do override AbstractFormatter's stringToValue
method, like this: 如果链接腐烂,它表示你真正需要做的就是覆盖AbstractFormatter的stringToValue
方法,如下所示:
public Object stringToValue(String text) throws ParseException {
Pattern pattern = getPattern();
if (pattern != null) {
Matcher matcher = pattern.matcher(text);
if (matcher.matches()) {
return super.stringToValue(text);
}
throw new ParseException("Pattern did not match", 0);
}
return text;
}
