Again a problem with Translation

[franco.amato]

Hi ( wysota do not despair ).
I achieved to translate my mainwindow to other language reading settings ( at the moment I don't implemented a dynamic translation yet ).
From my window I can open a 'settings' dialog pressing a button.
I translated EVERY file having tr() but I don't understand why the dialog has not been translated.
Must I do it in another way?

Regards

[genjix]

can you be a bit more specific (show some code?) so we can help you?

EDIT: lol dude, I just read your other posts. BE EXPLICIT IN EVERYTHING YOU SAY!! we are not mind readers

[franco.amato]

This is the problem:
I read settings when the application starts. In the settings there is a language entry. In my case I can choose between english (en) and spanish (es).
Every string in the source code is written in english and wrapped with tr(). So if I choose es in the configuration all in the main window is well translated from english to spanish ( I provide to the application a *.qm file produced with linguist ). The problem is that the dialog ( that I exec from the appplication is not translated ). The *.qm file contains also translations for the dialog strings and I don't understand why they are not well translated.
I attach here a screenshoot translation.jpg explaining my problem.
This is the better way I can explain my problem.

Franco... some code, please. I will not repeat myself and will only ask for enough information this one time. If you don't provide enough information yourself, I will not respond to your post. If you are lucky enough, maybe someone else will.

Hello Franco.

Do you have two *.qm files ? Or for application and dialogs you have exactly one *.qm file ?
If you have more than one qm files, you have to create more QTranslator objects...

Here the code to run the dialog that's not translated as the rest of the application:

void MainWindow::configure()
{
	// Create the dialog at run-time 
	ConfigDlg dialog(  this );
	// and execute it
	dialog.exec();
}

void MainWindow::configure()
{
	// Create the dialog at run-time 
	ConfigDlg dialog(  this );
	// and execute it
	dialog.exec();
}

The ui of the dialog is done using designer and I set every string translable ( sorry for the term ).
Please let me know if you need more code. I can send to you the ui file if you want.

And again your translator goes out of scope too early.

And again your translator goes out of scope too early.

Wysota it goes out of scope? So Qt translate the dialogs in the same moment of their creation? Do I well understood?

[Leszek]

Add member to class MainWindow, like

QTranslator m_translator;

QTranslator m_translator;

To copy to clipboard, switch view to plain text mode 

In CTOR changes like below:

....
readSettings(); // <-- here I read settings ( also language entry )
if( QString::compare(m_language,"es") == 0 )
{
   m_translator.load("ecpstudio_es");
   qApp->installTranslator(&esTranslator);
}

....
readSettings(); // <-- here I read settings ( also language entry )
if( QString::compare(m_language,"es") == 0 )
{
   m_translator.load("ecpstudio_es");
   qApp->installTranslator(&esTranslator);
}

Yes this is what I did after the reply of wysota thank you.
It works.

Doesn't it?

Qt translates dialogs when results of appropriate tr() calls are assigned to widgets' visible text. There is no magic here anywhere.
