QTranslator??

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

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

Code:

---

<!DOCTYPE TS><TS>
<defaultcodec>iso8859-1</defaultcodec>
<context>
    <name>QRadioButton</name>
    <message>
        <source>English</source>
        <translation type="unfinished">Xin </translation>
    </message>
	<name>QRadioButton</name>
    <message>
        <source>Swedish</source>
        <translation type="unfinished">Xin2 </translation>
    </message>
</context>
</TS>

THanks

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

Example of a problem? :D

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

The pro file:

Code:

---

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

---

The program:

Code:

---

#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();
}

---

Then:

Code:

---

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

---

Output:

Code:

---

"Es muy fácil!"

---

Try changing the loaded translation.

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

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.

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

Code:

---

hellotr

---

project and check

Code:

---

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

---

Thanks

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?

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

Where did you put these files?

The same directory
C:\dev\Qt\2010.05\qt\examples\linguist\hellotr

Code:

---

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

---

Copy them elsewhere, run qmake and make.

Dead easy... I really cannot see the problem

Code:

---

$ cd /tmp
$ cp -r /usr/share/qt4/examples/linguist/hellotr .
$ cd hellotr
$ qmake
$ make
 
$ lupdate hellotr.pro
...
Updating 'hellotr_la.ts'...
    Found 1 source text(s) (1 new and 0 already existing)
$ linguist hellotr_la.ts  # translate the string
$ lrelease hellotr.pro
...
Updating '/tmp/hellotr/hellotr_la.qm'...
    Generated 1 translation(s) (1 finished and 0 unfinished)
$ ./hellotr
