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
