tr with #define..it can work?

[mattia]

thanks so much now it correctly works, but when i compile my application i keep having this annoying massage:

default.h:48: warning: ‘greeting_string’ defined but not used

default.h:48: warning: ‘greeting_string’ defined but not used

To copy to clipboard, switch view to plain text mode 

greeting_string is declared in this wy:

static const char *greeting_string = QT_TRANSLATE_NOOP( "mainWindow" , "Hello" );

static const char *greeting_string = QT_TRANSLATE_NOOP( "mainWindow" , "Hello" );

To copy to clipboard, switch view to plain text mode 

and it's used in mainWindow.
thx
