than you didn‘t read carefully enough the docs even have an example
https://doc.qt.io/qt-5/qtlinguist-hellotr-example.html

a compileable one.

@J.Hilk yes, I read..
Tries to load a file called hellotr_la.qm (the .qm file extension is implicit) that contains Latin translations for the source texts used in the program. No error will occur if the file is not found.

but I would like see an exaple of file ts to see how I must write it

[mrjj]

Hi
No, the translation is not automatic.
You use lupdate to extract the texts to the TS
Then qt linguist to open and help translate
then qt linguist can compile the ts to qm
and you load the qm version to translate the app.

But try to do the sample @J-Hilk links.
Its very basic and shows the procedure very well.

@mrjj ok, I found a tutorial, tomorrow I try, thanks anyway

Hi
Just a note.

• but I would like see an exaple of file ts to see how I must write it

You don't write the ts file your self. that part is from extracting the texts with the tool

@mrjj I found an example in youTube, without see I didn't understand, I solved, I used prompt di comandi, thanks anyway

[mrjj]

@vale88
Ok. super :)

[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.

It'd be great you can share the link so other users in your same condition could benefit.

In addition, since your issue seems solved, please don't forget to update your post. Thanks.

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.

[A Former User]

@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.

[A Former User]

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

[mrjj]

@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?

[A Former User]

@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
