qtranslator with dynamic labels

[A Former User]

@mrjj only a thing..if I change something in my project, must I recreated my file ts? or I can update it

[mrjj]

@vale88
You can update it.
Just like how you created it first time.
It will then add new texts to the file.

but 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...is it normal?

[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

[mrjj]

@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.

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:

[A Former User]

@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

[A Former User]

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

[mrjj]

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

@mrjj thanks
