+ If you use QSettings from many places in your application, you

+ QSettings constructor:
- QMutexLocker locker(globalMutex());
- PathHash *pathHash = pathHashFunc();
- if (pathHash->isEmpty())
- initDefaultPaths(&locker);
+ QSettings stores settings. Each setting consists of a QString
+ that specifies the setting's name (the \e key) and a QVariant
+ that stores the data associated with the key. To write a setting,
+ use setValue().
- QString result = pathHash->value(pathHashKey(format, scope));

+ If there already exists a setting with the same key, the existing
+ value is overwritten by the new value. For efficiency, the
+ changes may not be saved to permanent storage immediately. (You
+ can always call sync() to commit your changes.)
- // fall back on INI path
- return pathHash->value(pathHashKey(QSettings::IniFormat, scope));
-}
+ You can get a setting's value back using value(). If there is no
+ setting with the specified name, QSettings returns a null QVariant
+ (which can be converted to the integer 0). You can specify
+ another default value by passing a second argument to value():

-/*!
- \class QSettings
- \brief The QSettings class provides persistent platform-independent application settings.
-
- \ingroup io
-
- \reentrant
-
- Users normally expect an application to remember its settings
- (window sizes and positions, options, etc.) across sessions. This
- information is often stored in the system registry on Windows,
- and in XML preferences files on Mac OS X. On Unix systems, in the
- absence of a standard, many applications (including the KDE
- applications) use INI text files.
-
- QSettings is an abstraction around these technologies, enabling
- you to save and restore application settings in a portable
- manner. It also supports \l{registerFormat()}{custom storage
- formats}.
-
- QSettings's API is based on QVariant, allowing you to save
- most value-based types, such as QString, QRect, and QImage,
- with the minimum of effort.
-
- If all you need is a non-persistent memory-based structure,
- consider using QMap<QString, QVariant> instead.
-
- \tableofcontents section1
-
- \section1 Basic Usage
-
- When creating a QSettings object, you must pass the name of your
- company or organization as well as the name of your application.
- For example, if your product is called Star Runner and your
- company is called MySoft, you would construct the QSettings
- object as follows:
-
- \snippet doc/src/snippets/settings/settings.cpp 0
-
- QSettings objects can be created either on the stack or on
- the heap (i.e. using \c new). Constructing and destroying a
- QSettings object is very fast.
-
- If you use QSettings from many places in your application, you
- might want to specify the organization name and the application
- name using QCoreApplication::setOrganizationName() and
- QCoreApplication::setApplicationName(), and then use the default
- QSettings constructor:
-
- \snippet doc/src/snippets/settings/settings.cpp 1
- \snippet doc/src/snippets/settings/settings.cpp 2
- \snippet doc/src/snippets/settings/settings.cpp 3
- \dots
- \snippet doc/src/snippets/settings/settings.cpp 4
-
- (Here, we also specify the organization's Internet domain. When
- the Internet domain is set, it is used on Mac OS X instead of the
- organization name, since Mac OS X applications conventionally use
- Internet domains to identify themselves. If no domain is set, a
- fake domain is derived from the organization name. See the
- \l{Platform-Specific Notes} below for details.)
-
- QSettings stores settings. Each setting consists of a QString
- that specifies the setting's name (the \e key) and a QVariant
- that stores the data associated with the key. To write a setting,
- use setValue(). For example:
-
- \snippet doc/src/snippets/settings/settings.cpp 5
-
- If there already exists a setting with the same key, the existing
- value is overwritten by the new value. For efficiency, the
- changes may not be saved to permanent storage immediately. (You
- can always call sync() to commit your changes.)
-
- You can get a setting's value back using value():
-
- \snippet doc/src/snippets/settings/settings.cpp 6
-
- If there is no setting with the specified name, QSettings
- returns a null QVariant (which can be converted to the integer 0).
- You can specify another default value by passing a second
- argument to value():
-
- \snippet doc/src/snippets/settings/settings.cpp 7
-
- To test whether a given key exists, call contains(). To remove
- the setting associated with a key, call remove(). To obtain the
- list of all keys, call allKeys(). To remove all keys, call
- clear().
+ To test whether a given key exists, call contains(). To remove
+ the setting associated with a key, call remove(). To obtain the
+ list of all keys, call keys(). To get a map of all settings, call
+ map(). To remove all keys, call clear().
\section1 QVariant and GUI Types
conversion functions to data types such as QColor, QImage, and
QPixmap, which are part of \l QtGui. In other words, there is no
\c toColor(), \c toImage(), or \c toPixmap() functions in QVariant.
-
Instead, you can use the QVariant::value() or the qVariantValue()
- template function. For example:
-
- \snippet doc/src/snippets/code/src_corelib_io_qsettings.cpp 0
+ template function.
The inverse conversion (e.g., from QColor to QVariant) is
automatic for all data types supported by QVariant, including
- GUI-related types:
-
- \snippet doc/src/snippets/code/src_corelib_io_qsettings.cpp 1
+ GUI-related types.
Custom types registered using qRegisterMetaType() and
qRegisterMetaTypeStreamOperators() can be stored using QSettings.
\section1 Section and Key Syntax
- Setting keys can contain any Unicode characters. The Windows
- registry and INI files use case-insensitive keys, whereas the
- Carbon Preferences API on Mac OS X uses case-sensitive keys. To
- avoid portability problems, follow these simple rules:
+ Setting keys can contain any Unicode characters. To avoid portability
+ problems, follow these simple rules:
\list 1
\o Always refer to the same key using the same case. For example,
example, if you have a key called "MainWindow", don't try to
save another key as "mainwindow".
- \o Do not use slashes ('/' and '\\') in section or key names; the
- backslash character is used to separate sub keys (see below). On
+ \o Do not use slashes ('/' and '\\') in key names. The backslash
+ character is used to separate sub keys (see below). On
windows '\\' are converted by QSettings to '/', which makes
them identical.
\endlist
You can form hierarchical keys using the '/' character as a
- separator, similar to Unix file paths. For example:
-
- \snippet doc/src/snippets/settings/settings.cpp 8
- \snippet doc/src/snippets/settings/settings.cpp 9
- \snippet doc/src/snippets/settings/settings.cpp 10
-
- If you want to save or restore many settings with the same
- prefix, you can specify the prefix using beginGroup() and call
- endGroup() at the end. Here's the same example again, but this
- time using the group mechanism:
-
- \snippet doc/src/snippets/settings/settings.cpp 11
- \codeline
- \snippet doc/src/snippets/settings/settings.cpp 12
+ separator, similar to Unix file paths.
- If a group is set using beginGroup(), the behavior of most
- functions changes consequently. Groups can be set recursively.
-
- In addition to groups, QSettings also supports an "array"
- concept. See beginReadArray() and beginWriteArray() for details.
-
- \section1 Fallback Mechanism
-
- Let's assume that you have created a QSettings object with the
- organization name MySoft and the application name Star Runner.
- When you look up a value, up to four locations are searched in
- that order:
-
- \list 1
- \o a user-specific location for the Star Runner application
- \o a user-specific location for all applications by MySoft
- \o a system-wide location for the Star Runner application
- \o a system-wide location for all applications by MySoft
- \endlist
-
- (See \l{Platform-Specific Notes} below for information on what
- these locations are on the different platforms supported by Qt.)
-
- If a key cannot be found in the first location, the search goes
- on in the second location, and so on. This enables you to store
- system-wide or organization-wide settings and to override them on
- a per-user or per-application basis. To turn off this mechanism,
- call setFallbacksEnabled(false).
-
- Although keys from all four locations are available for reading,
- only the first file (the user-specific location for the
- application at hand) is accessible for writing. To write to any
- of the other files, omit the application name and/or specify
- QSettings::SystemScope (as opposed to QSettings::UserScope, the
- default).
-
- Let's see with an example:
-
- \snippet doc/src/snippets/settings/settings.cpp 13
- \snippet doc/src/snippets/settings/settings.cpp 14
-
- The table below summarizes which QSettings objects access
- which location. "\bold{X}" means that the location is the main
- location associated to the QSettings object and is used both
- for reading and for writing; "o" means that the location is used
- as a fallback when reading.
-
- \table
- \header \o Locations \o \c{obj1} \o \c{obj2} \o \c{obj3} \o \c{obj4}
- \row \o 1. User, Application \o \bold{X} \o \o \o
- \row \o 2. User, Organization \o o \o \bold{X} \o \o
- \row \o 3. System, Application \o o \o \o \bold{X} \o
- \row \o 4. System, Organization \o o \o o \o o \o \bold{X}
- \endtable
-
- The beauty of this mechanism is that it works on all platforms
- supported by Qt and that it still gives you a lot of flexibility,
- without requiring you to specify any file names or registry
- paths.
-
- If you want to use INI files on all platforms instead of the
- native API, you can pass QSettings::IniFormat as the first
- argument to the QSettings constructor, followed by the scope, the
- organization name, and the application name:
-
- \snippet doc/src/snippets/settings/settings.cpp 15
-
- The \l{tools/settingseditor}{Settings Editor} example lets you
- experiment with different settings location and with fallbacks
- turned on or off.
+ If you want to use specific format instead of the native, you
+ can pass QSettings::IniFormat as the first argument to the
+ QSettings constructor, followed by the scope.
\section1 Restoring the State of a GUI Application
- QSettings is often used to store the state of a GUI
- application. The following example illustrates how to use QSettings
- to save and restore the geometry of an application's main window.
-
- \snippet doc/src/snippets/settings/settings.cpp 16
- \codeline
- \snippet doc/src/snippets/settings/settings.cpp 17
-
+ QSettings is often used to store the state of a GUI application.
See \l{Window Geometry} for a discussion on why it is better to
- call QWidget::resize() and QWidget::move() rather than QWidget::setGeometry()
- to restore a window's geometry.
+ call QWidget::resize() and QWidget::move() rather than
+ QWidget::setGeometry() to restore a window's geometry.
The \c readSettings() and \c writeSettings() functions must be
- called from the main window's constructor and close event handler
- as follows:
-
- \snippet doc/src/snippets/settings/settings.cpp 18
- \dots
- \snippet doc/src/snippets/settings/settings.cpp 19
- \snippet doc/src/snippets/settings/settings.cpp 20
- \codeline
- \snippet doc/src/snippets/settings/settings.cpp 21
-
- See the \l{mainwindows/application}{Application} example for a
- self-contained example that uses QSettings.
+ called from the main window's constructor and close event handler.
\section1 Accessing Settings from Multiple Threads or Processes Simultaneously
- QSettings is \l{reentrant}. This means that you can use
- distinct QSettings object in different threads
- simultaneously. This guarantee stands even when the QSettings
- objects refer to the same files on disk (or to the same entries
- in the system registry). If a setting is modified through one
+ QSettings is \l{reentrant}. This means that you can use distinct
+ QSettings object in different threads simultaneously. This
+ guarantee stands even when the QSettings objects refer to the
+ same files on disk. If a setting is modified through one
QSettings object, the change will immediately be visible in
any other QSettings objects that operate on the same location
and that live in the same process.
\section2 Locations Where Application Settings Are Stored
- As mentioned in the \l{Fallback Mechanism} section, QSettings
- stores settings for an application in up to four locations,
+ QSettings stores settings for an application in two locations,
depending on whether the settings are user-specific or
- system-wide and whether the settings are application-specific
- or organization-wide. For simplicity, we're assuming the
- organization is called MySoft and the application is called Star
- Runner.
+ system-wide. For simplicity, we're assuming the application is
+ called MySoft.
On Unix systems, if the file format is NativeFormat, the
following files are used by default:
\list 1
- \o \c{$HOME/.config/MySoft/Star Runner.conf} (Qt for Embedded Linux: \c{$HOME/Settings/MySoft/Star Runner.conf})
- \o \c{$HOME/.config/MySoft.conf} (Qt for Embedded Linux: \c{$HOME/Settings/MySoft.conf})
- \o \c{/etc/xdg/MySoft/Star Runner.conf}
- \o \c{/etc/xdg/MySoft.conf}
+ \o \c{$HOME/.config/MySoft.json}
+ \o \c{/etc/xdg/MySoft.json}
\endlist
If the file format is IniFormat, the following files are
used on Unix:
\list 1
- \o \c{$HOME/.config/MySoft/Star Runner.ini} (Qt for Embedded Linux: \c{$HOME/Settings/MySoft/Star Runner.ini})
- \o \c{$HOME/.config/MySoft.ini} (Qt for Embedded Linux: \c{$HOME/Settings/MySoft.ini})
- \o \c{/etc/xdg/MySoft/Star Runner.ini}
+ \o \c{$HOME/.config/MySoft.ini}
\o \c{/etc/xdg/MySoft.ini}
\endlist
- The SystemScope settings location is determined from the installation
- drive and Secure ID (UID3) of the application. If the application is
- built-in on the ROM, the drive used for SystemScope is \c c:.
-
- The paths for the \c .ini and \c .conf files can be changed using
- setPath(). On Unix, the user can override them by setting the
- \c XDG_CONFIG_HOME environment variable; see setPath() for details.
-
- \section2 Accessing INI and .plist Files Directly
-
- Sometimes you do want to access settings stored in a specific
- file or registry path. On all platforms, if you want to read an
- INI file directly, you can use the QSettings constructor that
- takes a file name as first argument and pass QSettings::IniFormat
- as second argument. For example:
+ The paths for the \c .ini and \c .json files can be changed by the
+ user by setting the \c XDG_CONFIG_HOME environment variable.
- \snippet doc/src/snippets/code/src_corelib_io_qsettings.cpp 2
+ \section2 Accessing Files Directly
- You can then use the QSettings object to read and write settings
- in the file.
+ Sometimes you do want to access settings stored in a specific file.
+ If you want to read an INI file directly, you can use the QSettings
+ constructor that takes a file name as first argument and pass
+ QSettings::IniFormat as second argument. You can then use the
+ QSettings object to read and write settingsin the file.
