Detailed Description
Class for producing and handling localized messages.
KLocalizedString
handles translation and argument substitution and formatting of user-visible text.
KLocalizedString
instances are usually not constructed directly, but through one of the wrapper *i18n*
calls.
For detailed information on how to use KI18n functions please refer to Programmer's Guide.
Definition at line 44 of file klocalizedstring.h.
Constructor & Destructor Documentation
◆ KLocalizedString() [1/2]
|
explicit |
Construct an empty message.
Direct construction is used when another KLocalizedString
instance, obtained by one of ki18n*
calls, should later be assigned to directly constructed instance. Before the assignment happens, directly constructed instance is not valid for finalization by toString
methods.

◆ ~KLocalizedString()
KLocalizedString::~KLocalizedString | ( | ) |

Member Function Documentation
◆ addDomainLocaleDir()
|
static |
Load locales for a domain from a specific location This is useful for resources which have their translation files outside of the usual $XDG_DATA_DIRS/locales location.
- Parameters
-
the domain to load resources from \path the full file path to the locale directory
Definition at line 1387 of file klocalizedstring.cpp.
◆ applicationDomain()
|
static |
Get the application's main translation domain.
Returns the domain set by setApplicationDomain
.
Definition at line 1215 of file klocalizedstring.cpp.
◆ availableApplicationTranslations()
- Since
- 5.0
Get the languages for which there exists the translation catalog file for the set application translation domain.
The application domain is set by setApplicationDomain
. If the application domain was not set, empty set is returned. If the application domain was set, the language set will always contain at least the source code language (en_US
).
- Returns
- set of language codes for existing translation catalogs
- See also
- setApplicationDomain
Definition at line 1254 of file klocalizedstring.cpp.
◆ availableDomainTranslations()
|
static |
- Since
- 5.0
Get the languages for which a translation catalog file for the passed translation domain exists.
If the translation domain was not specified in the domain parameter an empty set is returned.
If the application domain was set, the language set will always contain at least the source code language (en_US
).
- Parameters
-
domain query for translations of a specific domain, if an empty QByteArray is passed, an empty set will be returned
- Returns
- set of language codes for existing translation catalogs
Definition at line 1259 of file klocalizedstring.cpp.
◆ clearLanguages()
|
static |
Clear override languages.
This clears the override languages, going back to those provided by the locale.
- See also
- setLanguages
- languages
Definition at line 1238 of file klocalizedstring.cpp.
◆ ignoreMarkup()
KLocalizedString KLocalizedString::ignoreMarkup | ( | ) | const |
Do not resolve KUIT markup.
If the message is markup-aware (constructed by one of *xi18n*
calls), this function can be used to make it non-markup-aware. This may be useful for debugging markup.
- Returns
- updated
KLocalizedString
Definition at line 1194 of file klocalizedstring.cpp.
◆ inContext()
KLocalizedString KLocalizedString::inContext | ( | const QString & | key, |
const QString & | value ) const |
Add dynamic context to the message.
See dyn_ctxt for use cases.
- Parameters
-
key context key value context value
- Returns
- updated
KLocalizedString
Definition at line 1180 of file klocalizedstring.cpp.
◆ isApplicationTranslatedInto()
|
static |
Check whether the translation catalog file in the given language for the set application translation domain exists.
- Parameters
-
language the language code to check
- Returns
true
if the translation catalog forlanguage
exits,false
otherwise
- See also
- setApplicationDomain
Definition at line 1247 of file klocalizedstring.cpp.
◆ isEmpty()
bool KLocalizedString::isEmpty | ( | ) | const |
Check whether the message is empty.
The message is considered empty if the object was constructed via the default constructor.
Empty messages are not valid for finalization. The behavior of calling toString
on them is undefined. In debug mode, an error mark may appear in the returned string.
- Returns
true
if the message is empty,false
otherwise
Definition at line 407 of file klocalizedstring.cpp.
◆ languages()
|
static |
Get the languages for which translations will be made.
Returned languages are ordered with decreasing priority.
- Returns
- languages ordered list of language codes
- See also
- setLanguages
- clearLanguages
- Since
- 5.20.0
Definition at line 1222 of file klocalizedstring.cpp.
◆ localizedFilePath()
Find a path to the localized file for the given original path.
This is intended mainly for non-text resources (images, sounds, etc). Text resources should be handled in more specific ways.
Possible localized paths are checked in turn by priority of set languages, in form of <dirname>/l10n/<lang>/<basename>
, where <dirname>
and <basename>
are those of the original path, and <lang>
is the language code.
- Parameters
-
filePath path to the original file
- Returns
- path to the localized file if found, original path otherwise
Definition at line 1356 of file klocalizedstring.cpp.
◆ operator=()
KLocalizedString & KLocalizedString::operator= | ( | const KLocalizedString & | rhs | ) |
Assignment operator.
Definition at line 394 of file klocalizedstring.cpp.
◆ relaxSubs()
KLocalizedString KLocalizedString::relaxSubs | ( | ) | const |
Relax matching between placeholders and arguments.
Normally the placeholders should start from %1 and have no gaps, and on finalization there must be exactly as many arguments supplied through subs
methods as there are unique plaecholders. If this is not satisfied, in debug mode warnings are printed and the finalized string may contain error marks.
This method relaxes the placeholder-argument matching, such that there must only be an argument available for every present unique placeholder (taking placeholder numbers to be 1-based indices into the argument list). This can come useful in some situations.
- Returns
- updated
KLocalizedString
Definition at line 1187 of file klocalizedstring.cpp.
◆ removeAcceleratorMarker()
Remove accelerator marker from a UI text label.
Accelerator marker is not always a plain ampersand (&), so it is not enough to just remove it by QString::remove
. The label may contain escaped markers ("&&") which must be resolved and skipped, as well as CJK-style markers ("Foo (&F)") where the whole parenthesis construct should be removed. Therefore always use this function to remove accelerator marker from UI labels.
- Parameters
-
label UI label which may contain an accelerator marker
- Returns
- label without the accelerator marker
Definition at line 1382 of file klocalizedstring.cpp.
◆ setApplicationDomain()
|
static |
Set the given domain as application's main domain.
This function must be called in applications, in order to have any translations at all. It should never be called in libraries. This allows to check whether the application is translated into a given language, so that if it is not, translations from underlying libraries will not appear even if they are translated. This prevents mixing of translated and untranslated text in the user interface.
This function should be called right after creating the instance of QCoreApplication or one of its subclasses. At that time the locale setup has been made, including what is hooked into the QCoreApplication startup, like KXMLGUI's language switching support. So the initialisation done by this function sees all the data it should.
- Parameters
-
domain the translation domain of the application
Definition at line 1206 of file klocalizedstring.cpp.
◆ setLanguages()
|
static |
Set the languages for which translations will be made.
This overrides the languages provided by the locale. Languages should be ordered with decreasing priority.
- Parameters
-
languages ordered list of language codes
- See also
- setLocale
- clearLanguages
- languages
