qtranslator with dynamic labels

[mrjj]

@vale88
Hi
Yes that is normal.
Only when you call setText , new text can be used if you loaded a installTranslator
in the mean time.

@mrjj a ok, is there a way to solve it?if I try manually it isn't work because there the translator

@vale88
Hi
Im not sure what you are doing.
After you loaded a new translator.
You must call setText on all Labels etc. to have them show translated text.

@mrjj maybe i understood what you say, but I shoul control the text of the label and then setText inside I think

@vale88
An alternative to fiddling around changing language at runtime.
You could allow the user to select the language. save the selection to a file
and load that in main. when app starts.
Then to use new language, all you have to do is restart app.

@vale88 said in qtranslator with dynamic labels:

ut I noticed that if I push in button english then labels are written in english because I put tr, but the labels just written in Italian aren't changed in english if I click button after

Could you please show both screenshot(s) of the issue and the corresponding snippet of source code?

@Pablo-J.-Rogina

void MainWindow::on_Traduzione_Inglese_clicked()
{

    qApp->installTranslator(&inglese);


    ui->Traduzione_Italiano->setDisabled(false);
  
    
}

there is also change event, if I click the button before that the label is written there is the translation
but if the label is written and then click the button for translation the label is empty:

@vale88 void MainWindow::changeEvent(QEvent* event)
{

if(event->type() == QEvent::LanguageChange)
{
    ui->retranslateUi(this);

    if(text=="CONF. CARICATA")
     ui->Info->setText("CONF. LOADED");

}

QWidget::changeEvent(event);

}
in this way it works, but it's manual

@Pablo-J.-Rogina is there a way less manual?

@vale88
Hi
Any widget that is not made with UI , must be manually handled.
That is, call its setText again.
