[Qt-interest] How to change the language at run time in the Application

[Santhosh Y]

Hi Thomas,

Thanks for the information. I have gone through it, but I am having a 
doubt that how
we will change a particular string in to a different language at run time.

Following is the example I am trying for. qMainwindow has some action 
"Language 1"
When the user clicks it in the run time, I want to change Qpushbutton 
text to the "Language 1" equivalent.

#My project file::
SOURCES = main.cpp

TRANSLATIONS = hellotr_lan1.ts 


MainWindow :: MainWindow ()
{
    QMenuBar* b = menuBar ();
    QMenu* m = b->addMenu ("Languages");

    myLan1 = new QAction(QAction::tr("Language 1", m));
    connect(myLan1, SIGNAL(triggered () ), this, SLOT (Lang1() ));
    m->addAction (myLan1);

    // button
    QPushButton* hello = new QPushButton(QPushButton::tr("Hello world!"));

    setCentralWidget (hello);
}

void
MainWindow::Lang1 ()
{
    QTranslator t;
    t.load("hellotr_lan1");
    qApp->installTranslator(&t);
}


Please help in this regard
