Main Window initialisation

[stampede]

Can you prepare and attach compilable example (I mean all needed files, .cpp, .h and .ui) so we can test it ?
edit:
and can you verify that LanguageChange event is not triggered ? I think all strings will be replaced to defaults set in designer if you call ui->retranslateUi(), you should place all setText(), setTitle() etc. code to be called in event handler in case of LanguageChange event.

Hi,

Here are the files.

Yes the retranslate is the problem. This is automatically generated by Qt creator wizard and it did not bother me until now.

I am not quite sure yet to understand the way that this language event loop works or the possible benefits for my gui. My gui is intended to a scientific audience who use english as main working/communication language so I would comment out this retranslate command for the time being.

You don't have to comment out anything, just set new strings and window titles in event handler during LanguageChange event:

void MainWindow::changeEvent(QEvent *e)
{
    QMainWindow::changeEvent(e);
    switch (e->type()) {
    case QEvent::LanguageChange:
        this->retranslate();
        break;
    default:
        break;
    }
}
 
void MainWindow::retranslate(){
     ui->retranslateUi(this);
     ui->pushButton->setText(tr("I changed the text"));
     setWindowTitle(tr("This is the title I would like to be"));       
}

void MainWindow::changeEvent(QEvent *e)
{
    QMainWindow::changeEvent(e);
    switch (e->type()) {
    case QEvent::LanguageChange:
        this->retranslate();
        break;
    default:
        break;
    }
}

void MainWindow::retranslate(){
     ui->retranslateUi(this);
     ui->pushButton->setText(tr("I changed the text"));
     setWindowTitle(tr("This is the title I would like to be"));       
}

To copy to clipboard, switch view to plain text mode 

In constructor call this->retranslate() and its done.
