What platform are you at? 
Might be related or not but in windows, the default is to write QSettings to the registry.

blocks|key|346562|text|据我所知，你不能检索路径。在Qt源代码src/corelib/io/qsettings.cpp中，有一个函数可以获取路径：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|346563|static+QString+getPath(QSettings::Format+format,+QSettings::Scope+scope)

As far as I can tell, you can't retrieve the path. In the Qt source, <code>src/corelib/io/qsettings.cpp</code>, there is a function to get the path:

<pre><code>static QString getPath(QSettings::Format format, QSettings::Scope scope)
{
 ...
</code></pre>

but it's not accessible from code using Qt. You can't copy it and use it either, because it uses internal Qt globals to store the path...

EDIT: A solution was posted, using <code>QDesktopServices.storageLocation(QDesktopServices.DataLocation)</code> but it doesn't do exactly what the question was asking for, i.e. if I set a custom path using <code>QSettings.setPath()</code> it doesn't reflect the change.

I read more into the question than there was as it was originally posted. It is clearer after the edits. Ok, so can't you use..

<pre><code>QString QSettings::fileName () const
</code></pre>

Returns the path where settings are written to using this <code>QSettings</code> object are stored.

On Windows, if the format is <code>QSettings::NativeFormat</code>, the return value is a system registry path, not a file path.

blocks|key|3121389|text|为什么需要知道设置路径？如果你打算把设置放进去，你可以使用QSettings。我可以看到创建一个子目录来保存各种设置，但似乎最简单的方法是直接使用QSettings。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3121390|entityMap^0|T|9|21|9|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

Why do you need to know the settings path? If you are going to put settings in it, you could use <code>QSettings</code>. I could see making a subdirectory to hold various settings, but it seems like the easiest way would be to use <code>QSettings</code> directly.

blocks|key|3121398|text|这可能不能直接回答您的问题:如果您想存储每个用户的持久数据，不应该使用QDesktopServices::storageLocation(QDesktopServices::DataLocation)吗？|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3121399|entityMap|0|LINK|mutability|MUTABLE|url|http://qt-project.org/doc/qt-4.8/qdesktopservices.html#storageLocation^0|Z|1T|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

This might not answer your question directly: if you want to store per-user persistent data, shouldn't you use <a href="http://qt-project.org/doc/qt-4.8/qdesktopservices.html#storageLocation" rel="noreferrer">QDesktopServices::storageLocation(QDesktopServices::DataLocation)</a> instead?

blocks|key|344355|text|这是一个令人讨厌的变通方法。首先创建QSettings，然后获取它的位置。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|344356|QSettings+cfg(QSettings::IniFormat,+QSettings::UserScope,

This is a nasty workaround. First you create <code>QSettings</code>, then get its location.

<pre><code>QSettings cfg(QSettings::IniFormat, QSettings::UserScope,
 "organization", "application");

QString config_dir = QFileInfo(cfg.fileName()).absolutePath() + "/";
</code></pre>

Credits go to the Qt Centre forum.

<code>QSettings</code> stores the default config in the user AppData directory. See documentation for <a href="http://qt-project.org/doc/qt-4.8/qsettings.html" rel="nofollow noreferrer"><code>QSettings</code></a>. Also this code instructs to store the config in the Ini file format.

blocks|key|349216|text|这在qt+4和qt+5上都有效。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|349217|QApplication::setApplicationName("MyApp");

#if+QT_VERSION+>=+0x050000

this works on both qt 4 and qt 5

<pre><code>QApplication::setApplicationName("MyApp");
QApplication::setOrganizationName("Me");

QString homePath;

#if QT_VERSION &gt;= 0x050000
 homePath = QStandardPaths::writableLocation(QStandardPaths::DataLocation);
#else
 homePath = QDesktopServices::storageLocation(QDesktopServices::DataLocation);
#endif
</code></pre>

<ul>
<li>linux: <code>$HOME/.config</code></li>
<li>windows: <code>%APPDATA%</code></li>
<li>mac os: <code>$HOME/.config</code></li>
</ul>

It can be set using <a href="http://qt-project.org/doc/qt-4.8/qsettings.html#setPath" rel="noreferrer">http://qt-project.org/doc/qt-4.8/qsettings.html#setPath</a>, but it seems as I am not able to retrieve it.

<a href="http://qt-project.org/doc/qt-4.8/qlibraryinfo.html#location" rel="noreferrer">http://qt-project.org/doc/qt-4.8/qlibraryinfo.html#location</a> <code>QLibraryInfo::LibrariesPath</code> returns the system wide settings dir, which is not what I want.

Any ideas, or do I have to code it separately for each platform?

€: I want to create a sub directory, and store files into it. (You may punish me if this is a bad idea)
