Dynamic translation - Dialog windows

[Wer_Bn]

Hello guys

I know how to translate my MainWindow:

myTranslator.load(":/languages/whateverLanguage.qm");

And then a changeEvent happens, where I filter it by QEvent::LanguageChange:

if(event->type() == QEvent::LanguageChange)
{
//here I set my special dynamic strings, for something not directly related with the .ui file
ui->retranslateUi(this);
}
QWidget::changeEvent(e);

The problem is that I use a different dialog in this application. And QDialog class has no retranslateUi function.

So, what should I do?
Retranslate them manually? With something like this for every label:

ui->thisLabel->setText(tr("Hello this is really not good looking"));

Or is there another way to automatically do this, like in MainWindow?

Thanks in advance

The problem is that I use a different dialog in this application. And QDialog class has no retranslateUi function.

retranslateUi is a function of the generate form class, not of QMainWindow.
It is therefore available for all widgets that are constructed vi

So, what should I do?
Retranslate them manually? With something like this for every label:

ui->thisLabel->setText(tr("Hello this is really not good looking"));

ui->thisLabel->setText(tr("Hello this is really not good looking"));

To copy to clipboard, switch view to plain text mode 

Well, "ui" looks like the pointer to a form class, so ui->retranslateUi(this);
But yes, if you don't have a form class, setting the strings again is the way to go.
retranslateUi does the same.

How do I know it's a form class?

It is derived from a QDialog and it has a .ui file associated with it.
But it certainly doesn't have retranslateUI

Can you attach the generated _ui.h file?

It is there... but I can't call it...
Why?

[anda_skoa]

How do you try to call it?
