[Interest] Dynamic translation using Qt Quick 2.x in Qt5.1.1

[Bo Thorsen]

It's one possibility to listen for a localeChange, yes. That has the 
advantage that it will catch the change no matter where it came from.

But since language changes don't happen automatically I usually emit the 
signal after setting the new QTranslator myself. This has the advantage 
that I can switch the locale temporarily without all strings switching. 
I use temporary locales when writing config files with floats, for example.

Cheers,

Bo.
