tr with #define..it can work?

Hello, im my default.h i put:

Code:

---

#define aString "aString";

---

if i want to use aString as a QString in my project i used to do in this way

Code:

---

...
QString ( aString )
...

---

but if i want internazionalizzate it with "tr()" function what should i do?
i tried with tr

Code:

---

tr ( QString ( aString ) )

---

but i get this error

Code:

---

main.cpp:4396: error: no matching function for call to ‘main::tr(QString)’

---

thx

The tr signature is QObject::tr ( const char * sourceText, const char * comment = 0, int n = -1 ) .
So you can just pass aString:

Code:

---

QString translated = tr(aString);

---

good, now i don't get any error...but i did
lupdate project.pro
lrelease project.pro
i can't find the voice in my .ts file...

From http://doc.trolltech.com/4.3/i18n.ht...l-literal-text:

If you need to have translatable text completely outside a function, there are two macros to help: QT_TR_NOOP() and QT_TRANSLATE_NOOP(). They merely mark the text for extraction by the lupdate utility described below. The macros expand to just the text (without the context).

Why don't you do it this way ?

Code:

---

const QString astring = QObject::tr("astring"); // global or wrapped in singleton class

Did you include <QString>?

Btw, bender86 already pointed out the correct way to do it if you insist using defines.

Hi, i did as bender86 suggest, i added in my default.h this:

Code:

---

static const char *greeting_string = QT_TR_NOOP("Hellooooo");

---

and in my*ts file i translated greeting_string,

Code:

---

<message>
        <location filename="../default.h" line="47"/>
        <source>Hellooooo</source>
        <translation>Ciaooooooooooooooo</translation>
    </message>

---

but when i call tr(greeting_string) in my application i'm not able to see greeting_string translated...I can just read "Hellooooo".
With other QString in my application i I have not problem to see them translated.
Any hint?
thx

You must use QT_TRANSLATE_NOOP() outside class context. QT_TR_NOOP() is used inside class context.

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

Code:

---

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

---

greeting_string is declared in this wy:

Code:

---

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

---

and it's used in mainWindow.
thx
