Hello, you should use QStandardPaths. DataLocation is correct, it using
applicationName and organizationName from you QGuiApplication instance.

Hi,
i have some questions about what are the correct config and data paths
for an application.
The harbour faq [ https://harbour.jolla.com/faq#2.4.0 ] says that for
these paths a subfolder during run time named <HARBOUR_APP_NAME>
inside a folder defined by the XDG Base Directory Specification should
be used. My question is how to get these values using QT.
I though of using the QStandardPaths [
http://doc.qt.io/qt-5/qstandardpaths.html ] or the QProcessEnvironment
[ http://doc.qt.io/qt-5/qprocessenvironment.html ] modules, but i
don't know if i am getting the correct values.
Using the QStandardPaths module I get this output:
[D] main:66 - QStandardPaths::DataLocation:
"/home/nemo/.local/share/harbour-batzap/harbour-batzap"
[D] main:67 - QStandardPaths::GenericDataLocation:
"/home/nemo/.local/share"
[D] main:68 - QStandardPaths::CacheLocation:
"/home/nemo/.cache/harbour-batzap/harbour-batzap"
[D] main:69 - QStandardPaths::GenericCacheLocation:
"/home/nemo/.cache"
[D] main:70 - QStandardPaths::TempLocation: "/tmp"
[D] main:71 - QStandardPaths::ConfigLocation: "/home/nemo/.config"
[D] main:72 - QStandardPaths::GenericConfigLocation:
"/home/nemo/.config"
(i'm returning these values using: /qDebug() <<
"QStandardPaths::<enum-name>: " <<
QStandardPaths::writableLocation(QStandardPaths::<enum-name>);/
According to the harbour faq, for application data the
$XDG_DATA_HOME/<harbour-name> folder should be used, ( freedesktop.org
<http://freedesktop.org> says that a possible value for $XDG_DATA_HOME
is "$HOME/.local/share/", so i'll assume that value, and assuming
<harbour-name> is "harbour-batsap") should the correct application
data folder be "/home/new/.local/share/harbour-batzap"
insted "/home/new/.local/share/harbour-batzap/harbour-batzap" as qt
returns for QStandardPaths::DataLocation?
Note: the qt docs suggest that
/QStandardPaths::AppDataLocation/ should be used while
/QStandardPaths::DataLocation/ is a deprecated value. But i'm getting
errors (/AppDataLocation /is not a member of /QStandardPaths/) using
/QStandardPaths::AppDataLocation/ (it was introduced in Qt 5.4, i
really don't remember what Qt5 version jolla ships)
If i try to get the values of the XDG variables using the
QProcessEnvironment module, i'm always getting blank values:
[D] main:75 -
QProcessEnvironment::systemEnvironment().value("$XDG_DATA_HOME"): ""
[D] main:76 -
QProcessEnvironment::systemEnvironment().value("XDG_DATA_HOME"): ""
[D] main:77 -
QProcessEnvironment::systemEnvironment().value("$XDG_CACHE_HOME"): ""
[D] main:78 -
QProcessEnvironment::systemEnvironment().value("XDG_CACHE_HOME"): ""
[D] main:79 -
QProcessEnvironment::systemEnvironment().value("$XDG_CONFIG_HOME"): ""
[D] main:80 -
QProcessEnvironment::systemEnvironment().value("XDG_CONFIG_HOME"): ""
(i'm returning these values using: /qDebug() <<
"QProcessEnvironment::systemEnvironment().value(<variable>, "");/
/
/
Using qDebug() << "getenv(<variable>): " << /getenv(<variable>);/ also
returns me an empty value:
[D] main:81 - getenv("XDG_DATA_HOME"):
[D] main:82 - getenv("$XDG_DATA_HOME"):
[D] main:83 - getenv("XDG_CACHE_HOME"):
[D] main:84 - getenv("$XDG_CACHE_HOME"):
[D] main:85 - getenv("XDG_CONFIG_HOME"):
[D] main:86 - getenv("$XDG_CONFIG_HOME"):
/
/
I'm executing the app thought qtcreator in my jolla device (deploying
it as an RPM package).
What are the correct path values? and how should I get them throught qt?.
Thanks!
