KDE Frameworks 5 Migration

This page summarises the steps required for the migration form KLocale to Qlocale in KDE Frameworks 5.

Global locale

Qt does not have an equivalent to KGlobal::locale(), i.e. application level locale settings, it only has the Qt default and system locales which apply at system-wide level.

Qt also doesn't offer setXxx() api in QLocale to allow apps to override a setting while running, and probably never will. Usually in KDE this is abused for things like temp changes to the date format when the normal format options api should be used, or a different locale object created. This will be the correct way to do so in Frameworks.

For example:

KGlobal::locale()->setDateFormat("%y-%M-%d");
label->setText(KGlobal::formatDate(myDate));

When it should be:

label->setText(KGlobal::formatDate(myDate, "%y-%M-%d"));

And under Qt5 will become:

label->setText(QLocale().toString(myDate, "yyyy-MM-dd"));


KGlobal::locale() returns the application's locale, which defaults to the system locale unless set different using KLocale::setLocale()

QLocale() constructs the default locale which is the system locale unless set different using QLocale::setDefaultLocale() QLocale::system() will always return the system locale.


So change all KGlobal::locale().xxx() references to QLocale().xxx()???

Would we want a QApplication::locale() ???

Side-note: QLocale::setDefaultLocale() could be used in KDE4 Workspace with a custom QSystemLocale to force all Qt apps to use the KDE settings!

API Migration

Locale

KLocale(const QString &catalog, KSharedConfig::Ptr config=KSharedConfig::Ptr()) KLocale(const QString &catalog, const QString &language, const QString &country=QString(), KConfig *config=0)

void reparseConfiguration()

static void splitLocale(const QString &locale, QString &language, QString &country, QString &modifier, QString &charset)

Countries

QLocale uses an enum value where KDE uses the ISO Code. Support may be added to Qt to convert between the two, or this may be provided in the planned QtIsoCodes addon.


KLocale Qt 5.0 Qt 5.1
ISO codes as strings enum Country Conversion methods to be added
allCountriesList() None, loop from QLocale::AnyCountry to QLocale::LastCountry To be added
QString country() Country country() or name.split('_').at(1) Provide ISO conversion methods
QString countryCodeToName(QString country) QString nativeCountryName() or QString countryToString(Country country) Add nativeCountryName(Country country) ???
QString defaultCountry() QLocale::C
bool setCountry(QString country, KConfig *config) QLocale(Language language, Country country)
QString countryDivisionCode () const Not used anywhere
bool setCountryDivisionCode (const QString &countryDivision) Not used anywhere

Languages

QLocale uses an enum value where KDE uses the ISO Code. Support may be added to Qt to convert between the two, or this may be provided in the planned QtIsoCodes addon.

KLocale Qt 5.0 Qt 5.1
ISO codes as strings enum Language Conversion methods to be added
QStringList allLanguagesList() const None, loop from QLocale::AnyLanguage to QLocale::LastLanguage To be added
QString language() Language language() or name.split('_').at(0) Provide ISO conversion methods
QString languageCodeToName(QString language) nativeLanguageName() or languageToString(Language language) Add nativeLanguageName(Language language) ???
QStringList languageList() uiLanguages()
static QString defaultLanguage() QLocale::C
bool setLanguage(QStringList languages) - KDE Platform module
bool setLanguage(const QString &language, KConfig *config) QLocale(Language language, Country country)
