[Qt-interest] Applying RightToLeft for whole application

[Tony Rietwyk]

Hi, 
 
Did you include the Qt arabic translations in :/lang/ar ?  Just having Yes and No translated is not enough, it needs to match the context specified in the QMessageBox code. 
 
Does the locale name message appear in arabic correctly?  A screen shot might help.  
 
Tony.

Hi guys,




For applying right to left layout I use setLayoutDirection function for each container (QWdiget, QMainWindow... etc) in some cases (I faced it) it's really exhausted procedure so I'm wondering:




Can I applying layout direction for whole application by single line?




PS

I tried to use setLayoutDirection with QApplication varialble but it didn't work!




int main(int argc, char *argv[]) 

{
    QApplication a(argc, argv);
    MainWindow w;
    a.setLayoutDirection(Qt::RightToLeft);
    w.show();
    return a.exec();
}

There is out code solution which passing -reverse argument. Can I use -reverse somehow inside my code for geting its benefit?


Sorry, It's working well when I use setLayoutDirection in main() but it's not when I use it from MainWindow... see this slot:

void MainWindow::on_actionInstant_Translation_triggered() 
{
    QTranslator translator;
    if(qApp->isRightToLeft())
    {
        if(!translator.load(":/lang/en"))
            qDebug()<<QObject::tr("Couldn't load English language");
//        this->setLayoutDirection(Qt::LeftToRight);
        qApp->setLayoutDirection(Qt::LeftToRight);
    }
    else
    {
        if(!translator.load(":/lang/ar"))
            qDebug()<<QObject::tr("Couldn't load Arabic language");
//        this->setLayoutDirection(Qt::RightToLeft);
        QLocale::setDefault(QLocale(QLocale::Arabic, QLocale::SyrianArabRepublic));
        qApp->setLayoutDirection(Qt::RightToLeft);
    }
    qApp->installTranslator(&translator);
    ui->retranslateUi(this);
    QLocale local;
    /** 
      BUG: QMessageBox buttons didn't appear in Arabic for Arabic local language $ RTL layout
      */
    QMessageBox::information(this, "", QLocale::languageToString(local.language()), QMessageBox::Yes|QMessageBox::No);
}
