[Qt-interest] Translation of text taken from db

[KC Jones]

Assuming it is a fixed set of strings that is known at compile time,
you could force them to appear in code by defining a map from the
untranslated string to the localized one and use that to translate.
Costs time and RAM, but if the string table is not too large it would
work.  I have a small set of keywords in a db table that I plan to use
this approach for.

class Foo {
[...]
public:
    Foo() {
      if (xlate.isEmpty()) {
        xlate["stop"]=tr("stop");
        xlate["go"]=tr("go");
        // etc....
      }
    }
    QString xlate(const QString& dbstring) const
    {
      return xlate[dbstring]; // maybe add code to check existence of
string in table...
    }
private:
    static QHash<QString, QString> xlate;
}
QHash<QString, QString> Foo::xlate;
