wxTextEntryDialog translation of OK and Cancel - c++

Question

I have my application with all the translations working perfectly except the 'OK' and 'Cancel' contained in the wxTextEntryDialog dialog. How can I get these to translate properly? Even the wxMessageBox is working fine when using OK and Cancel but wxTextEntryDialog doesn't just seem to translate to any other language.
I have used the following snippets for the languages assignment within my code:
wxLocale m_locale; // locale we'll be using (this is defined in the header file of my app)
// Within the source
lang = wxLANGUAGE_CHINESE_SIMPLIFIED; // for e.g. could be any language
m_locale.Init(lang);
// normally this wouldn't be necessary as the catalog files would be found in the default locations, but when the program is not installed the
// catalogs are in the build directory where we wouldn't find them by default
wxLocale::AddCatalogLookupPathPrefix(wxT(LanguagePath));// add path of install
// Initialize the catalogs we'll be using
m_locale.AddCatalog(_("messages")); // .mo file generated by my application language specific .mo file
Thanks in advance for any help.

Answer 1

Does your call to Init() succeed? You should really check for its return value, it's possible that it doesn't find wxstd.mo, which contains translations for all the messages used inside wxWidgets, because you call it before setting the lookup path. You need to
Ensure that wxstd.mo is available in your catalog path.
Call Init() after setting this path.
Check its return value.

Thanks #VZ. for the insight. Your approach helped me debug my application better i.e. I was able to see that the Init() did not succeed by checking the return value. With this I was able to investigate further. Also, the wxstd.mois just the default .po generated .mo (not translated so why would I require this?)
Solution: I had to add the wxWidgets translation files i.e. the .mo generated catalog files from the .po files contained in the <wxdir>/locale/. I had to copy them to the same directories as my messages.mo. Hence, the working code looks like this for Simplified chinese.
wxLocale m_locale; // locale we'll be using (this is defined in the header file of my app)
// Within the source
lang = wxLANGUAGE_CHINESE_SIMPLIFIED; // for e.g. could be any language
wxLocale::AddCatalogLookupPathPrefix(wxT(LanguagePath));// add path of install
m_locale.Init(lang, wxLOCALE_CONV_ENCODING);
m_locale.AddCatalog(wxT("zh_CN")); // This is the .mo file I generated from the wxWidgets .po files
// Initialize the catalogs we'll be using
m_locale.AddCatalog(_("messages")); // .mo file generated by my application language specific .mo file
I did not include the checks for a purpose because I want the application to run in english even if the language is not supported but I did use it for debugging
