Switch QTranslator at runtime?

[whitefurrows]

How can i change QTranslator dynamic? I try this:

int main(int argc, char** argv)
{
QApplication app( argc, argv );
 
//...
 
if (language=="de"){
   QTranslator* translator = new QTranslator();
   translator->load(":/translation/language + ".qm");
   app.installTranslator(translator);
}
 
//...
}
 
___________________________________________________________________________
 
 
void ApplicationSetup::switchLanguage()
{
   static QTranslator* translator=0; 
 
   if (translator) 
   { 
      qApp->removeTranslator(translator); 
      delete translator; 
   } 
 
   translator = new QTranslator(0); 
 
   if (language =="en") 
   {
      translator->load(":/translation/language + ".qm"); 
      qApp->installTranslator( translator ); 
   }
}

int main(int argc, char** argv)
{
QApplication app( argc, argv );

//...

if (language=="de"){
   QTranslator* translator = new QTranslator();
   translator->load(":/translation/language + ".qm");
   app.installTranslator(translator);
}

//...
}

void ApplicationSetup::switchLanguage()
{
   static QTranslator* translator=0; 

   if (translator) 
   { 
      qApp->removeTranslator(translator); 
      delete translator; 
   } 

   translator = new QTranslator(0); 

   if (language =="en") 
   {
      translator->load(":/translation/language + ".qm"); 
      qApp->installTranslator( translator ); 
   }
}

To copy to clipboard, switch view to plain text mode 

The language don’t change at runtime. I use ui-files and classes code by hand. All strings look like this tr("Please translate me").

Can somebody tell me how can i translate all strings in all open widgets at runtime?

Thanks in advance,
