感谢您的回复和示例。
不幸的是，滑块不起作用，因为只有大约20个有效值，它们不仅仅是相关的。
目前，用户键入一个值，但必须知道哪些值是可接受的。
我找到了一个相当粗略的解决方案，即将下拉输出写入文件，然后将其读入实际值。
它不优雅，但确实有效。编辑：pi于2014年3月17日上午8:49

Thanks for the response and example. Unfortunately a slider will not work as there are only about 20 valid values and they are not simply related. At present the user types in a value but has to know which values are acceptable.
I have found a rather crude solution which is to write the drop-down output to a file and then read it into a real value. It is not elegant but does work.
