Multilingual application

If you are using the main C++ distribution of wxWidgets, Feel free to ask any question related to wxWidgets development here. This means questions regarding to C++ and wxWidgets, not compile problems.

I also try:

Code: Select all

	m_locale.Init(wxLANGUAGE_ENGLISH, wxLOCALE_CONV_ENCODING); //wxLOCALE_CONV_ENCODING Deprecated
	wxLocale::AddCatalogLookupPathPrefix(wxT(".\\langs"));
	m_locale.AddCatalog(wxT("es_ES"));
But it does not work either

Try a tool like Procmon and check in which paths the executable is looking for the translation files.

I use my own translation solution for my own texts, but for the wxWidgets translation files, i had to put them in this path:

Code: Select all

<exedir>/locale/de_DE/wxstd.mo
Use the source, Luke!

Procmon = Process monitor?

I get this:

You may also check the output of the i18 debug trace, which shows the looked-up paths and files, as described here viewtopic.php?f=1&t=42414#p171997

ProcMon: https://technet.microsoft.com/en-us/sys ... nitor.aspx

Add a filter so that it only displays output for your exe and let it show only file events. You will still get hundreds of events when you start your app.
Use the source, Luke!

Hello,

In my own codes, I manage location of the language catalogs like this:

Code: Select all

    #ifdef __WXMSW__
    #ifdef _DEBUG
    m_strLangsBase = ::NormalizePathSep(wxPathOnly(argv[0]) + "/../../lang");
    #else
    m_strLangsBase = ::NormalizePathSep(wxPathOnly(argv[0]) + "/lang");
    #endif
    #endif // __WXMSW__
    #ifdef __WXOSX__
    m_strLangsBase = ::NormalizePathSep(wxPathOnly(argv[0]) + "/../Resources");
    #endif // __WXOSX__
Also, just an added info on a secondary point : as stated at http://docs.wxwidgets.org/trunk/group__ ... 96ec864160, I quote:
Note that since wxWidgets 2.9.0 you shouldn't use wxT() anymore in your program sources (it was previously required if you wanted to support Unicode).
It's now implicit.

I keep trying

I have made sure that the files are on the path but it still does not work

It would be ideal to find a turorial updated and explained in detail. I really do not understand how with the work that it costs to make these tools then there is hardly official documentation

About the routes it can not find I do not understand why you ask for them. Nowhere have I seen that I have to create anything in a folder called LC_MESSAGES as well as many others

If you don't succeed with a relative path, go back to a known point and use an absolute harcoded one in your code for the moment. When all will be OK, you'll just have to fix this single point (since hardcoded absolute path is obviously not a good idea for your final release).

And to check if a file exists, you simply have wxFileExists() in stock.

The ProcessMonitor output looks to me like the "es_ES" catalog is found. How do you check if it was successful?

How I use an absolute harcoded one?

How use wxFileExists() in this. I can't use for example

Code: Select all

wxFileExists(m_locale.AddCatalog(wxT("es_ES")))

I don't understand doublemax. I don't know how check it. ProcessMonitor says some routes found and others not. What path are the right? All?

Whell, first error:

Code: Select all

	m_locale.Init(wxLANGUAGE_SPANISH);//Init to the spanish
	wxLocale::AddCatalogLookupPathPrefix(wxT(".\\langs"));//add path
	m_locale.AddCatalog( wxT ("es"));//add catalog wxWidgetspath/locale/es.mo
	m_locale.AddCatalog(wxT("es_ES"));//add my .mo edit files
Move this lines before //(*AppInitialize

So

Code: Select all

	m_locale.Init(wxLANGUAGE_SPANISH);//Init to the spanish
	wxLocale::AddCatalogLookupPathPrefix(wxT(".\\langs"));//add path
	m_locale.AddCatalog( wxT ("es"));//add catalog wxWidgetspath/locale/es.mo
	m_locale.AddCatalog(wxT("es_ES"));//add my .mo edit files
    //(*AppInitialize
    bool wxsOK = true;
    wxInitAllImageHandlers();
    if ( wxsOK )
    {
    	MultilingualExampleFrame* Frame = new MultilingualExampleFrame(0);
    	Frame->Show();
    	SetTopWindow(Frame);
    }
    //*)
Now load the default language right. The path is: lang\es_ES\es_ES.mo

For change language into to program I have a menu to set language.

Code: Select all

void MultilingualExampleFrame::OnMenu_Language_Spanish_Selected(wxCommandEvent& event)
{
	wxLocale* locale;
	long language=wxLANGUAGE_SPANISH;
	locale = new wxLocale( language );
	locale->AddCatalogLookupPathPrefix(wxT(".\\langs\\es_ES"));
	locale->AddCatalog( wxT ("es_ES.po"));
}
This change texts of parents windows but no in the main frame; menus, form, etc.

How I can set language in runtime?

You can't - at least not with little effort. Store the new language, tell the user the app needs a restart and restart. As this doesn't happen often, i think it's an acceptable compromise.

Also keep in mind that sometimes additional software might be required to properly display international symbols.
Or just a properly generated locale on the system.

Thank you.
