QTranslator??

[nthung]

I am coding a program multilanguage, as
http://www.java2s.com/Code/Cpp/Qt/UsingQTranslator.htm
but I don't know how to make data. Could you create a data for me?
thanks

[ChrisW67]

I could create "a data" for you but then I would be the one "coding a program multilanguage"

It is all there in the docs: Linguist manual

This is may data, but it is still errors

Are we supposed to guess what you are doing with that file, what is generating an error message, and what that message is?

When i open it by

Qt Linguist

it has no error or warning.

[ChrisW67]

Uh huh. So what is the problem then?

Could you give me an full example with its data?
Thanks

Example of a problem?

[ChrisW67]

I like this problem: Fermat's Last Theorem Simple statement of problem, devilishly complex answer

The pro file:

TEMPLATE = app
TARGET = 
DEPENDPATH += .
INCLUDEPATH += .
 
# Input
SOURCES += main.cpp
 
TRANSLATIONS += \
    simple_example_es.ts \
    simple_example_fr.ts

TEMPLATE = app
TARGET = 
DEPENDPATH += .
INCLUDEPATH += .

# Input
SOURCES += main.cpp

TRANSLATIONS += \
    simple_example_es.ts \
    simple_example_fr.ts

To copy to clipboard, switch view to plain text mode 

The program:

#include <QtCore>
#include <QDebug>
 
int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);
 
    QTranslator translator;
    translator.load("simple_example_es");
//    translator.load("simple_example_fr");
    app.installTranslator(&translator);
 
    qDebug() << QObject::tr("It is easy enough!");
 
    return app.exec();
}

#include <QtCore>
#include <QDebug>

int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);

    QTranslator translator;
    translator.load("simple_example_es");
//    translator.load("simple_example_fr");
    app.installTranslator(&translator);

    qDebug() << QObject::tr("It is easy enough!");

    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

Then:

qmake
lupdate simple_example.pro 
linguist simple_example_es.ts  // input your translations to Spanish and mark as finished
linguist simple_example_fr.ts  // ditto for French
lrelease  simple_example.pro 
make
./simple_example

qmake
lupdate simple_example.pro 
linguist simple_example_es.ts  // input your translations to Spanish and mark as finished
linguist simple_example_fr.ts  // ditto for French
lrelease  simple_example.pro 
make
./simple_example

To copy to clipboard, switch view to plain text mode 

Output:

"Es muy fácil!"

"Es muy fácil!"

To copy to clipboard, switch view to plain text mode 

Try changing the loaded translation.

Apologies to any Spanish speakers if I have mangled your language... that's a Google Translate.

[nthung]

thanks so much.
Could you post data for me to run.?Because i don't see an example about data.
this is an example
http://doc.qt.nokia.com/latest/linguist-trollprint.html
but i can not run it as introduction.

[wysota]

What data do you want? Chris gave you a complete example with all the files.

[nthung]

What data do you want? Chris gave you a complete example with all the files.

I alway thanks you so much for good supports.
But I want to run one of examples in installed directory(C:\dev\Qt\2010.05\qt\examples\linguist) to understand about QTranslator.
I run them but none of them can run. I run lupdate, lrelease commands them raise erorrs. Maybe Qt installed incorrectly?
When i run

hellotr

hellotr

To copy to clipboard, switch view to plain text mode 

project and check

bool resultLaod=translator.load("hellotr_la");
then the resultLaod=false.

bool resultLaod=translator.load("hellotr_la");
then the resultLaod=false.

Thanks

[wysota]

What do you do step by step to build an example?

[nthung]

What do you do step by step to build an example?

Could you send me the one of examples then i run successfully?
Do you think that I installed Qt incorrectly?

[wysota]

No I couldn't. What good would it be if I send you the same files you already have? Just answer my previous question.

[nthung]

No I couldn't. What good would it be if I send you the same files you already have? Just answer my previous question.

thanks
I opened it by QtCreator then run
This is my project

Where did you put these files?

Where did you put these files?

The same directory

bool resultLaod=translator.load("hellotr_la");
then the resultLaod=false.

bool resultLaod=translator.load("hellotr_la");

Copy them elsewhere, run qmake and make.

Dead easy... I really cannot see the problem
