Re: [SailfishDevel] Folder permissions
QDir::homePath() inside app
while deploying you shouldnt copy anything to home. /usr/share for const
predefined data. $HOME/.local/share/appname for any downloaded/created
internal (!) application data like caches. Downloaded media you can save
in Video/Pictures/Music folders.
For settings use QSettings class and set default values in code like:
bool mySetting = settings.getValue("mySetting", true).toBool();
And remember: we can help you make your application better, we cant help
you continue development in bad direction.

Is this another "feature" of the QtCreator IDE? And when I say

on the emulator or the device from inside the IDE and I would have to
resolve to command line again?

You should clarify why you need write permissions, so that it's possible
to suggest the best way to handle your situation. In general, files
distributed as part of the rpm should never be written to.
If it's only things like config files or high scores that you need to
write, then there's standard ways to do it. They should be placed into
the user's home directory on first startup of your game, either by being
created from scratch, or by copying an initial version from your
/usr/share directory. (But don't hardcode /home. The best way to get the
path is to use QStandardPaths::writableLocation.)
I tried to use the /usr/share/$$(TARGET) folder where $$(TARGET) is the
name of my game but it seams the game doesn't have permissions on this
folder. Not even read permissions.
No, you should have read permissions. You just can't write.
I use:
FILE* pFile = fopen("/usr/share/MyGame/Home/settings.bin", "r+b");
That's not read permissions, You're asking for *both* read and write
permissions, which is denied because you can only have read permissions,
not write. To request read permissions only, use just "rb", not "r+b".

The Harbour FAQ has several detailed answers about where to ship (sic) read-only data in an RPM and where to store data at run-time: "Can I install files in /home/nemo?” https://harbour.jolla.com/faq#2.4.0 "I have a huge amount of data files which the user can edit/change during run time. What can I do?” https://harbour.jolla.com/faq#2.5.0 "Why can't I set a folder or a file under /usr/share// to be world writeable?” https://harbour.jolla.com/faq#2.12.0 “Where should I store application configuration, application data and cache files?” https://harbour.jolla.com/faq#2.13.0 “$XDG_CONFIG_HOME, $XDG_DATA_HOME and $XDG_CACHE_HOME are not set in the device environment. So which path should I use?” https://harbour.jolla.com/faq#2.14.0 For implementing XDG basedir, there’s a library, plus two README files (one for when you use Qt and one for when you use GLib, as both already implement XDG basedir): https://github.com/sailfish-sdk/xdg-helper HTH :) Thomas ___ SailfishOS.org Devel mailing list
