How to use libsailfishapp in your project
To use libsailfishapp in your project:
BuildRequires: pkgconfig(sailfishapp)to your .spec file
TARGET = harbour-yourappnamein your .pro file
CONFIG += sailfishappto your .pro file
sailfishapp.hin your .cpp file
- Use the
SailfishApp::methods in your
In the rest of this document, we will refer to the value of the
TARGET variable in your .pro file as
$$TARGET (this is also how you can use the variable itself in the .pro file).
Files that get installed by libsailfishapp, and have to be present in the same directory as the .pro file:
$$TARGET.png– An 86×86 pixel application icon
$$TARGET.desktop– The .desktop file for your app
qml/– A folder containing all your QML files
If you want to opt out of automatic deployment of the
qml/ folder, set
CONFIG += sailfishapp_no_deploy_qml before adding the sailfishapp configuration option. You might want to set this option if for some reason you intend to ship your QML files as Qt Resources (qrc). We recommend that you keep the default setup and install QML files in the filesystem instead.
How to use i18n support in your project
To use the internationalization convenience features of libsailfishapp:
- In your main .pro file, add:
CONFIG += sailfishapp_i18n
If you use id based translations also add:
CONFIG += sailfishapp_i18n_idbased
make(this will create or update the file
translations/$APPNAME.tsand all files in TRANSLATIONS)
- In your RPM packaging .yaml file, add the following entry to the files section:
To add a new language to your project:
- In your main .pro file, add (with $LANG replaced with the language):
TRANSLATIONS += translations/$APPNAME-$LANG.ts(for example, for German, use “$APPNAME-de.ts”, etc…)
If during development you want to skip building the translations every time, you can simply comment out the line
CONFIG += sailfishapp_i18n
in your qmake .pro file, and the translations will not be built/updated. Be sure to re-enable the line when you do the release build.

Storing application configuration files
To store application configuration files, you can use the standard
QSettings class with the default constructor, which will use the application and organization name (set correctly by libsailfishapp to the application name, which is the binary name in case of C++ applications or the first argument in case of QML-only applications with the
Storing application data and cached files
To store application data, use the location returned by
To store cache files (these files can be removed at any time by the system if disk space is low, and these files are not guaranteed to be backed up), use the location returned by
You can also use the Qt Quick Local Storage API to store data directly from your QML-only Sailfish Application. libsailfishapp will make sure that your application uses a application-specific storage directory.
