[yuvarajragupathi]

Hi,

My application should support different languages. Currently i am trying with Japanese. But it is not displayed. My code is

main.cpp


#include <QApplication>
#include <QTranslator>
#include "form.h"
int main(int argc, char *argv[])
{

QApplication app(argc, argv);
QTranslator translator;
translator.load(":/translations/i18n_jp.qm");
qApp->installTranslator(&translator);
Form *window = new Form ;
window->show();
return app.exec();
}


form.cpp

#include "form.h"
#include "ui_form.h"

Form::Form(QWidget *parent) :
QWidget(parent),
ui(new Ui::Form)
{
ui->setupUi(this);
ui->label->setText(tr("Hello"));
this->setWindowTitle(tr("Internationalization Example"));
}

Form::~Form()
{
delete ui;
}


form.h


#ifndef FORM_H
#define FORM_H

#include <QWidget>

namespace Ui {
class Form;
}

class Form : public QWidget
{
Q_OBJECT

public:
explicit Form(QWidget *parent = 0);
~Form();

private:
Ui::Form *ui;
};

#endif // FORM_H

Try this:
translator.load("translations/i18n_jp");

And make sure you convert the .ts files from QLinguist by clicking File->Release
