QSettings with translation

[franco.amato]

Hi to all,
I would know how set the settings of my application to manage translation.
For example if I choose english, when I restart the application I would have english as language.

Best Regards

What have you already done to try and solve your problem?

What have you already done to try and solve your problem?

pass a file path, set a QString, but I would know if there is a specific setting

[wysota]

So does it work or not? If not, what doesn't work?

Doesn't work! If I change language it always load the same.
So I ask again: is there a specific setting for language translation?

[wysota]

So how exactly do you store the setting?

So how exactly do you store the setting?

void MainWindow::closeEvent(QCloseEvent *ce )
{
	Q_UNUSED(ce);
	writeSettings();
}

void MainWindow::closeEvent(QCloseEvent *ce )
{
	Q_UNUSED(ce);
	writeSettings();
}

I'm not sure that storing the settings in the current working directory is a good idea. Anyway, how does the reading part look like? Also does the configuration file get created? Does it have proper contents?

So how must I do?

Anyway, how does the reading part look like?

It works for all settings except for the language

Also does the configuration file get created? Does it have proper contents?

Yes the content of the ini file is correct

[wysota]

So how must I do?

Either store the settings in a "well known location" like the user's home directory or use the application binary directory or let Qt choose the proper location.

Please provide enough information for us to see how you try to apply the language change using your settings. I'm tired of having to drag every piece of information out of you. If you want help, provide enough information to see where the problem might be. And do it always, not only in this thread, you have already over 400 posts on this forum, for God's sake! Every thread of yours is at least 5 times longer than questions asked by others. If you have problem with specifying your problem, maybe you should take a look at how others do it.

How can I let Qt decide where? Can I speak with Qt and ask where it would store the configuration file?

Please wysota give a look at your replies. They are also written with Morse code, and I always have to ask 'please can you be more clear' or I always have to beg for 2 lines of clarifing code of example as in the above statement ( let Qt decide where ).
I'm sure I'm not the only person thinking that.
I stopped to post questions in the 'Programming' sections hoping to have more clear replies (to improve my Qt level) but is not so.

and you read your settings file how?

[franco.amato]

and you read your settings file how?

This is my routine to read settings:

void MainWindow::readSettings()
{
	QSettings settings("config.ini", QSettings::IniFormat);
	/* language group */
	settings.beginGroup("language");
	    m_language = settings.value("lang", "en").toString();
	settings.endGroup();
	/* paths group */
	settings.beginGroup("paths");
		m_w1SourceDir = settings.value("w1_source",  "C:").toString();
		m_w2SourceDir = settings.value("w2_source",  "C:").toString();
		m_w1OutputDir = settings.value("w1_output",  "C:").toString();
		m_w2OutputDir = settings.value("w2_output",  "C:").toString();
	settings.endGroup();
	/* background file */
	settings.beginGroup("background");
		m_bgFile   = settings.value("file", "./audio de fondo/Grabacion_marca de agua_cruz report - MONO.mp3").toString();
		m_loopMode = settings.value("loop_mode", "loop").toString();
		m_loopInterval = settings.value("loop_interval", 5).toInt();
    settings.endGroup();
	/* steps */
	settings.beginGroup("steps");
		m_sstep = settings.value("sec", 1).toInt();
		m_mstep = settings.value("min", 1).toInt();
	settings.endGroup();
	/* colors group */
	settings.beginGroup("colors");
	QColor defColor = Qt::white;
	QVariant colVariant = defColor;
	m_bgColor = settings.value( "background", colVariant ).value<QColor>();
	m_wfColor = settings.value( "waveform",   Qt::darkBlue ).value<QColor>();
	m_tlColor = settings.value( "timeline",   Qt::darkRed ).value<QColor>();
	m_mkColor = settings.value( "markers",    Qt::yellow ).value<QColor>();
	m_slColor = settings.value( "selection",  Qt::red ).value<QColor>();
	settings.endGroup();
}

void MainWindow::readSettings()
{
	QSettings settings("config.ini", QSettings::IniFormat);
	/* language group */
	settings.beginGroup("language");
	    m_language = settings.value("lang", "en").toString();
	settings.endGroup();
	/* paths group */
	settings.beginGroup("paths");
		m_w1SourceDir = settings.value("w1_source",  "C:").toString();
		m_w2SourceDir = settings.value("w2_source",  "C:").toString();
		m_w1OutputDir = settings.value("w1_output",  "C:").toString();
		m_w2OutputDir = settings.value("w2_output",  "C:").toString();
	settings.endGroup();
	/* background file */
	settings.beginGroup("background");
		m_bgFile   = settings.value("file", "./audio de fondo/Grabacion_marca de agua_cruz report - MONO.mp3").toString();
		m_loopMode = settings.value("loop_mode", "loop").toString();
		m_loopInterval = settings.value("loop_interval", 5).toInt();
    settings.endGroup();
	/* steps */
	settings.beginGroup("steps");
		m_sstep = settings.value("sec", 1).toInt();
		m_mstep = settings.value("min", 1).toInt();
	settings.endGroup();
	/* colors group */
	settings.beginGroup("colors");
	QColor defColor = Qt::white;
	QVariant colVariant = defColor;
	m_bgColor = settings.value( "background", colVariant ).value<QColor>();
	m_wfColor = settings.value( "waveform",   Qt::darkBlue ).value<QColor>();
	m_tlColor = settings.value( "timeline",   Qt::darkRed ).value<QColor>();

	m_slColor = settings.value( "selection",  Qt::red ).value<QColor>();
	settings.endGroup();

I installed 2 translation files in the main.cpp so:

QApplication app(argc, argv);
 
 QTranslator enTranslator;
 enTranslator.load( "ecpstudio_en");
 app.installTranslator( &enTranslator );
 
 QTranslator esTranslator;
 esTranslator.load( "ecpstudio_es");	
 app.installTranslator( &esTranslator );

QApplication app(argc, argv);
 
 QTranslator enTranslator;
 enTranslator.load( "ecpstudio_en");
 app.installTranslator( &enTranslator );
 
 QTranslator esTranslator;
 esTranslator.load( "ecpstudio_es");	
 app.installTranslator( &esTranslator );

then I perform a test on the m_language variable ( after read the configuration file )

if ( QString::compare(m_language, "en", Qt::CaseInsensitive) == 0 )
   // here I would do effective the english translation file
else
  // here I would do effective the spanish translation file

if ( QString::compare(m_language, "en", Qt::CaseInsensitive) == 0 )
   // here I would do effective the english translation file
else
  // here I would do effective the spanish translation file
