Hi

I want use WidgetBlueprint use in C++

I Make WidgetComponent and Want to Set WidgetBlueprintClass that component

WidgetComponent = CreateDefaultSubobject<UWidgetComponent>( TEXT( "widget " ) );

WidgetComponent->SetWidgetClass( BlueprintWidget->StaticClass( ) );

I Try Get WidgetBlueprint in C++

ConstructHelpder::Object Finer < UUserWidget >…

FStringClassReference MyWidgetClassRef( TEXT( “/Game/UI/BillBoardWidget.BillBoardWidget” ) );

But
include “Runtime/UMG/Public/Blueprint/UserWidget.h” …
I can See Compile Error Like This
