How to use the variables types?

Development Programming & Scripting C++
1

I’m trying to use https://docs.unrealengine.com/latest/INT/API/Runtime/Core/Internationalization/FInternationalization/GetCulturesWithA-/index.html but I always get this error: Unrecognized type ‘FCultureRef’. I never used c++ before.

Here’s how I’m doing it:



.h
UFUNCTION(BlueprintPure, meta = (DisplayName = "Get supported Culture Names"), Category = "Cultures")
	static TArray<FCultureRef> GetSupportedCultureNames(bool IncludeDerivedCultures = true);

-----

.cpp
TArray<FCultureRef> UMainMenuManagerOBJ::GetSupportedCultureNames(bool IncludeDerivedCultures)
{
	TArray<FCultureRef> Cultures;
	FInternationalization::Get().GetCulturesWithAvailableLocalization(FPaths::GetEditorLocalizationPaths(), Cultures, IncludeDerivedCultures);

	return Cultures;
}

I looked at the source but could no find anything to help me.
Thanks.

Did you include

Internationalization/Internationalization.h

in your .h file?

Yes, I had it included.

I tried the same and got this error to. Perhaps someone from the engine support staff might take a look at this. Here is what my crashdump logs for that error:

The definition of FCulteRef states that it is threadsafe. Perhaps that is something we must take into account here.


#include "SharedPointer.h"

class FCulture;

typedef TSharedPtr<FCulture, ESPMode::ThreadSafe> FCulturePtr;
typedef TSharedRef<FCulture, ESPMode::ThreadSafe> FCultureRef;

Thanks for the info, guess we’ll have to wait.

I’m also having trouble with this https://docs.unrealengine.com/latest/INT/API/Runtime/Core/Misc/FConfigCacheIni/ForEachEntry/index.html.
My question at answerhub: https://answers.unrealengine.com/questions/251964/read-each-entry-from-ini-file.html, which I will copy below.

I’m trying to do:


USManager::GetGameSettings(){
 
     FString Section = "GameSettings";
 
     GConfig->ForEachEntry(
         SOMETHING_HERE_I_DONT_KNOW_WHAT
         *Section,
         GGameIni
         );

         //return outSettings;
 
 }

Here is the function (from Engine/SourceRuntime/Core/Public/Misc/ConfigCacheIni):


bool FConfigCacheIni::ForEachEntry(const FKeyValueSink& Visitor, const TCHAR* Section, const FString& Filename)
{
    FConfigFile* File = Find(Filename, 0);
    if(!File)
    {
        return false;
    }

    FConfigSection* Sec = File->Find(Section);
    if(!Sec)
    {
        return false;
    }

    for(FConfigSectionMap::TIterator It(*Sec); It; ++It)
    {
        Visitor.Execute(*It.Key().GetPlainNameString(), *It.Value());
    }

    return true;
}

Breaking down to this part: **Visitor.Execute(It.Key().GetPlainNameString(), It.Value());

Found this: DECLARE_DELEGATE_TwoParams(FKeyValueSink, const TCHAR, const TCHAR);**

And this: https://docs.unrealengine.com/latest/INT/Programming/UnrealArchitecture/Delegates/index.html

-Edit 1
I’m getting somewhere now:

I made a class:


class FGetFromIni
{
public:
	static void OnEntry(const TCHAR *Key, const TCHAR* Value)
	{
	}

	static TArray<FString> KeyAndValues;
};

And im calling:



TArray<FString> OMSPlugin::GetFromIni(FString Section)
{	
	GConfig->ForEachEntry(FKeyValueSink::CreateStatic(&FGetFromIni::OnEntry), *Section, GGameIni);
	
	return FGetFromIni::KeyAndValues;

Now I’m getting the error: error LNK2001: unresolved external symbol "public: static class TArray<class FString,class FDefaultAllocator> FGetFromIni::KeyAndValues"
