Detailed Description

This is the main class of a Cutelyst appplication.

Configuration file options

There are some options you can set in your application configuration file in the Cutelyst section. If you want to get keys via the config() method of Application, you have to add them to the Cutelyst section. If you want to get other config sections than Cutelyst, you should use engine()->config("section").

home

Type: string Default: empty

Absolute path to your home diretory, that is for example used by pathTo(). If this is empty (the default), it will be populated by the return value of QDir::currentPath().

root

Type: string Default: empty

Absolute path to your web root directory that contains your template and/or static files. This might be used by plugins to serve static files or by Views like CuteleeView to find template files. If this is empty (the default), it will be populated as directory "root" below "home".

Constructor & Destructor Documentation

◆ Application()

Application::Application ( QObject * parent = nullptr )

explicit

The constructor is used to setup the class configuration, subclasses should only use this for objects that do not require configuration to be ready.

A Web Engine will instantiate your application through this class, next it will load the settings file, and in the end it will call init() which is where your application should do it’s own setup.

Warning: DO NOT register your controllers, plugins or anything that might want to use config() in here, do that in init()

Definition at line 47 of file application.cpp.

References loadTranslations().

◆ ~Application()

Application::~Application ( )

virtual

Destroys the Application object.

Definition at line 62 of file application.cpp.

Member Function Documentation

◆ addTranslator() [1/2]

void Application::addTranslator	(	const QLocale &	locale,
		QTranslator *	translator
	)

Adds a translator for the specified locale.

You can add multiple translators for different application parts for every supported locale. The installed translators will then be used by Context::translate() and Context::qtTrId() (which itself will use Application::translate()) to translate strings according to the locale set by Context::setLocale().

Note: You will most likely want to use loadTranslationsFromDir() or loadTranslationsFromDirs() instead of this function because they automatically load translations and set their locales.

Usage example:: bool MyCutelystApp::init()

{

// ...

auto trans = new QTranslator(this);

QLocale deDE(QLocale::German, QLocale::Germany);

if (trans->load(deDE, QStringLiteral("mycutelystapp"),

QStringLiteral("."),

QStringLiteral("/usr/share/mycutelystapp/l10n")) {

addTranslator(deDE, trans);

}

// ...

}

◆ addTranslator() [2/2]

void Application::addTranslator	(	const QString &	locale,
		QTranslator *	translator
	)

Adds a translator for the specified locale.

The locale string has to be parseable by QLocale.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ beforePrepareAction

void Cutelyst::Application::beforePrepareAction	(	Cutelyst::Context *	c,
		bool *	skipMethod
	)

signal

This signal is emitted before the Dispatcher is called to find an action. It’s useful if you need to intercept requests before they are dispatched. Always check skipMethod and return if it’s true. In case you want to stop further processing set skipMethod to true.

◆ config() [1/2]

QVariantMap Application::config ( ) const

◆ config() [2/2]

QVariant Application::config	(	const QString &	key,

◆ init()

bool Application::init ( )

protectedvirtual

Do your application initialization here, if your application should not proceed log some information that might help on debugging and return false.

For example if your application only works with PostgeSQL and the Qt driver is not available it makes sense to fail here. However you should not initialize resouces that cannot be shared among process.

See also: postFork

Returns: true if your application was successfuly initted

◆ inited()

bool Cutelyst::Application::inited ( ) const

Returns true if the application has been inited.

◆ loadTranslations()

void Application::loadTranslations	(	const QString &	filename,
		const QString &	directory = `{}`,
		const QString &	prefix = `{}`,
		const QString &	suffix = `{}`
	)

Loads translations for a specific filename from a single directory.

This can be used to load translations for a specific component or application if the translation file names follow a common schema.

Let us assume you organised your translation files as follows:

/usr/share/myapp/translations/myapp_de.qm
/usr/share/myapp/translations/myapp_pt_BR.qm
...

You can then use loadTranslations() in your reimplementation of Application::init() as follows:

bool MyApp::init()
{
     loadTranslations(QStringLiteral("myapp"),
                      QStringLiteral("/usr/share/myapp/translations"),
                      QStringLiteral("_"));
}

If directory is empty, the default directory, set by -DI18NDIR, will be used. prefix is the part between the file name and the locale part. In the example above it is "_", if it is not set the default "." will be used. The suffix is the file name suffix that defaults to ".qm".

		const QString &	directory = `QString()`,
		const QString &	prefix = `QStringLiteral(".")`,
		const QString &	suffix = `QStringLiteral(".qm")`
	)

Loads translations for a specific filename from a single directory and returns a list of added locales.

This can be used to load translations for a specific component or application if the translation file names follow a common schema.

Let us assume you organised your translation files as follows:

/usr/share/myapp/translations/myapp_de.qm

}

◆ loadTranslationsFromDirs()

QVector< QLocale > Application::loadTranslationsFromDirs	(	const QString &	directory,
		const QString &	filename
	)

Loads translations for a specific filename from a directory structure under directory and returns a list of added locales.

This can be used to load translations for a specific component or application if the the translation files are organized in subdirectories named after locale codes. Let us assume you organised your translation files as follows:

/usr/share/locale/de/LC_MESSAGES/myapp.qm
/usr/share/locale/pt_BR/LC_MESSAGES/myapp.qm
...

You can then use loadTranslationsFromDirs() in your reimplementation of Application::init() as follows:

bool MyApp::init()
{
    loadTranslationsFromDirs(QStringLiteral("/usr/share/locale"),
                             QStringLiteral("LC_MESSAGES/myapp.qm"));

◆ postFork()

bool Application::postFork ( )

protectedvirtual

This method is called after the engine forks

After the web engine forks itself it will call this function so that you can initialize resources that can’t be shared with the parent process, namely sockets and file descriptors.

A good example of usage of this function is when opening a connection to the database which can’t be shared with other processes and should probably make this function return false if it fails to open.

Default implementation returns true.

Returns: false if the engine should not use this process

bool Application::registerController ( Controller * controller )

protected

This method registers a Controller class which is responsible for handlying requests, since they are reused between multiple requests. Be aware of not storing data there, instead you might want to use a session plugin or the stash.

Parameters

	)

protected

Change the value of the configuration key.

This will change or add keys to the configuration read from the Cutelyst section of your configuration file. The set values are not written to the file.

Warning: You should never call this from random parts of the code as a way to store shareable data, it should only be called by a subclass

◆ shuttingDown

void Cutelyst::Application::shuttingDown ( Cutelyst::Application * app )

signal

This signal is likely to be emitted when the worker process should stop. At this point the application has a limited time to finish it’s operations. If a timeout is reached the application will get killed.

◆ translate()

QString Application::translate	(	const QLocale &	locale,
		const char *	context,
		const char *	sourceText,
		const char *	disambiguation = `nullptr`,
		int	n = `-1`
	)		const

Translates the sourceText into the target locale language.

This uses the installed translators for the specified locale to translate the sourceText for the given context into the target locale. Optionally you can use a disambiguation and/or the n parameter to translate a pluralized version.

Do not use this method directly but use Context::translate() or Context::qtTrId().
