Detailed Description

GrantleeView is a Cutelyst::View handler that renders templates using Grantlee engine.

This View also exports a Grantlee tag for dealing with Cutelyst::Context::uriFor():

{% c_uri_for "/path" "arg1" "arg2" QUERY "foo=bar" c.req.queryParams %}

Where only the path is required, and QUERY keyword must preceed query parameters

Member Function Documentation

◆ addTranslationCatalog()

void GrantleeView::addTranslationCatalog	(	const QString &	path,
		const QString &	catalog
	)

Dynamically adds translation catalog at path to the translator.

Translation catalogs can be used to dynamically integrate translations into the GrantleeView, for example for plugins and themes. The catalog could be the name of an extension for example that is loaded from a locale specifc directory under path.

The catalog will be loaded in the following way: /path/locale/catalog, for example /usr/share/mycutelystapp/l10n/de_DE/fancytheme.qm. The current locale is defined by Context::locale() when rendering the theme. The path /usr/share/myapp/l10n would then contain locale specific subdirectories like de_DE, pt_BR, etc. that contain the translation files named by catalog.

Usage example:: bool MyCutelystApp::init()

{

// ...

auto view = new GrantleeView(this);

view->addTranslationCatalog(QStringLiteral("/usr/share/mycutelystapp/l10n"), QStringLiteral("fancytheme"));

// ...

}

Since: Cutelyst 1.5.0

Definition at line 265 of file grantleeview.cpp.

◆ addTranslationCatalogs()

void GrantleeView::addTranslationCatalogs ( const QHash< QString, QString > & catalogs )

Adds a dictionary of translation catalogs and paths to the translator.

The key of the QHash is the name of the catalog, the value is the path. See addTranslationCatalog() for more information about translation catalogs.

Since: Cutelyst 1.5.0

Definition at line 273 of file grantleeview.cpp.

◆ addTranslator() [1/2]

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

Adds a translator for the specified locale to the list of translators.

Example usage: bool MyCutelystApp::init()

{

// ...

auto view = new GrantleeView(this);

auto deDeTrans = new QTranslator(this);

if (deDeTrans->load(QStringLiteral("de_DE"), QStringLiteral("/path/to/my/translations")) {

view->addTranslator(QLocale("de_DE"), deDeTrans);

}

auto ptBrTrans = new QTranslator(this);

if (ptBrTrans->load(QStringLiteral("pt_BR"), QStringLiteral("/path/to/my/translations")) {

view->addTranslator(QLocale("pt_BR"), ptBrTrans);

}

// ...

}

◆ addTranslator() [2/2]

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

Adds a translator for the specified locale to the list of translators.

The locale string should 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.

◆ engine()

Grantlee::Engine * GrantleeView::engine ( ) const

Returns the Grantlee::Engine pointer that is used by this engine.

Definition at line 131 of file grantleeview.cpp.

◆ loadTranslationsFromDir()

QVector< QLocale > GrantleeView::loadTranslationsFromDir	(	const QString &	filename,
		const QString &	directory,
		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 template if the translation file names follow a common schema. Let us assume you organised your translation files as follows:

/usr/share/myapp/translations/mytemplate_de.qm
/usr/share/myapp/translations/mytemplate_pt_BR.qm
...

You can then use loadTranslationsFromDir() on your registered GrantleeView object as follows:

bool MyApp::init()
{
     auto view = new GrantleeView(this);
     view->loadTranslationsFromDir(QStringLiteral("mytemplate"), QStringLiteral("/usr/share/myapp/translations"), QStringLiteral("_"));
}

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".

◆ preloadTemplates()

void GrantleeView::preloadTemplates ( )

When called cache is set to true and templates are loaded.

Definition at line 137 of file grantleeview.cpp.

References isCaching(), and setCache().

◆ render()

QByteArray GrantleeView::render ( Context * c ) const

finalvirtual

All subclasses must reimplement this when doing it's rendering. If an error (c->error()) is not set c->response()->body() is defined with the returned value, this is useful if the view is not meant to be used as a body.

Implements Cutelyst::View.
