简述
我有一个配置文件，其中一个组General ，怎么都读不出正确的值，全是空，但是别的组能读出来，改General2试试， 果然可以，就怀疑是不是组名称被内置了。
打开QSettings的帮助文档，搜索General ，有内容，看下解释
The INI file format has severe restrictions on the syntax of a key. Qt works around this by using % as an escape
character in keys. In addition, if you save a top-level setting (a key with no slashes in it, e.g., "someKey"),
it will appear in the INI file's "General" section. To avoid overwriting other keys,
if you save something using a key such as "General/someKey",
the key will be located in the "%General" section, not in the "General" section.
大概意思是说General 被内置了。。他就不能带个qt啥的么，影响我起名字
方法1
不要指组名称，直接读写就是General 中的信息，value(“key”)就可以了
方法2
显式用General读 ，如value(“General/key”)，在ini文件中被存为[%General ]
方法3
换个组名称，避免冲突
