Detailed Description

This class implements access to the Qt Localization system. Localizable types such as strings, numbers, dates and times can be processed.

auto t = m_engine->loadTemplate(someTemplate);
auto c = getContext();
 
// Render with the German locale
c.setLocalizer(m_de_Localizer);
auto deText = t->render(&c);
de_display->setText(deText);
 
// Render with the French locale
c.setLocalizer(m_fr_Localizer);
auto frText = t->render(&c);
fr_display->setText(frText);
