QT Translation - Multi Language Support

janga

Hi All,

I have written a code in QT where it creates four push buttons and then on clicking one of the Pushbutton button by name "Up" . All the names of buttons should be changed is my intention. I have generated the *.ts file and *.qm file using lupdate and lrelease. For your reference iam using QT creator.

But the names are not getting translated.

mainwindow.cpp code is as below

@
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

upButton = new QPushButton(tr("&Up"),this);
downButton = new QPushButton(tr("&Down"),this);
leftButton = new QPushButton(tr("&Left"),this);
rightButton = new QPushButton(tr("&Right"),this);

upButton->setGeometry(40,40,40,40);
downButton->setGeometry(80,40,40,40);
rightButton->setGeometry(80,80,40,40);
leftButton->setGeometry(40,100,40,40);

connect ( upButton,SIGNAL( clicked() ),this,SLOT( tion() ) );

}

void MainWindow::tion()

{
QTranslator qtTranslator;

if (qtTranslator.load(QString("C:\Users\janga\Desktop\Label\trans\sample.qm")))
{
QMessageBox abc;
abc.setText("abc");
abc.exec();
}
QApplication::installTranslator(&qtTranslator);

ui->retranslateUi(this&#41;;

}

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

main.cpp code is as below

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

MainWindow w;

w.show();

return a.exec(&#41;;

}
@

sample.ts file as below

@
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE TS>
<TS version="2.0">
<context>
<name>MainWindow</name>
<message>
<location filename="mainwindow.ui" line="14"/>

hi and welcome to devnet.

i cann't see in which language you want to convert your application?

Show me your .pro file

*Note : please add @ tags before and after your code.

Hi and welcome to devnet,

What you have to write in order to do dynamic translation can be found in the "Internationalization with Qt" chapter of Qt's documentation. More precisely under "Dynamic Translation"

IamSumit

hi
-show me your modified .pro file code.-

(Edited@IamSumit))

SGaist

It's not a pro file problem. The code from janga is not written to support dynamic translation.

janga

Can you please help me out for dynamic translation and or with any sample code

janga

THis is my pro file

QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = trans
TEMPLATE = app

SOURCES += main.cpp
mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui

TRANSLATIONS = sample.ts

janga

Its Very Urgent Can you people send me the code snippet for me or please suggest me any changes in my code

SGaist

Go to the documentation chapter I indicated, there's everything you need there including code.

janga

Thanks for the support. I got it

i have one more question
I am going to use eclipse IDE for QT GUI development.

Eclipse doesnt have QT plugins. Then how to use lupdate and lrelease.

Can i know how to use lupdate and lrelease manually.
