Change language interface on the fly Topic is solved

[dejudicibus]

My application support multiple language interfaces and locales. However, when the user select a new language, I have to store it in an INI file so that at the next launch it can be used. If I change the locale on the fly, the interface continue to use the current catalog, even if I use this code to swich it:

Code: Select all

wxLocale * wbxDictApp::SetLocale(wxLanguage lang)
{
  if (locale) delete locale ;
	locale = new wxLocale() ;

	// --- Enter block (~wxLogNull called at the end) ---
	{
		wxLogNull noLog ; // --- Prevent message "Cannot load locale" 
		locale->Init(lang) ;
	}

	// --- Load catalog ---
	locale->AddCatalogLookupPathPrefix(wbxSTR_LOCALE_PATH) ;
	bool loaded = locale->AddCatalog(wbxSTR_LOCALE_CAT) ;
	if (!loaded)
	{
		wxString msg = wxString::Format(wbxMSG_NOLOCALE, locale->GetLocale()) ;
		wbxWarningMessage(NULL, msg) ;

  	if (locale) delete locale ;
		locale = new wxLocale() ;

		// --- Load REAL English catalog ---
		// --- Enter block (~wxLogNull called at the end) ---
		{
			wxLogNull noLog ; // --- Prevent message "Cannot load locale" 
			locale->Init(wxLANGUAGE_ENGLISH) ;
		}

		// --- Load catalog ---
		locale->AddCatalogLookupPathPrefix(wbxSTR_LOCALE_PATH) ;
		loaded = locale->AddCatalog(wbxSTR_LOCALE_CAT) ;
	}

	return locale ;
}

Any way to switch interface language on the fly in 2.8.0?

Thank you. I have seen that the author uses wxDELETE rather than delete to destruct an istance. What's the advantage?

wxDELETE macro just checks if the pointer is equal to NULL and if it is not NULL-pointer then deletes allocated memory.

OK, so this is an old thread and this link is pointing to something about HTML Helps, so I'm guessing the page at this URL seems to have changed. Any idea where the original page is located now, or did I just miss your point?

I'm also interested in this matter as I'm trying to become an expert in L10N / I18N things
