I have got the following chunks of code:

## MenuWidget.h

```
DECLARE_EVENT_OneParam(UMenuWidget,OnClickedButtonOpenEvent,int);
	OnClickedButtonOpenEvent Var;

```

## MenuWidget.cpp

```
int send {8};
	Var.Broadcast(send);

```

## MyPlayerController.cpp

```
void AMyPlayerController::nothing2(int x) {
	GEngine->AddOnScreenDebugMessage(
		21,200,FColor::Yellow,FString::Printf(TEXT("nothing2(%d)"),x)
	);
}

```

How can I receive the event-broadcast here in **MyPlayerController.cpp** , to be attached to **AMyPlayerController::nothing2**?

I tried:

**NOTE:** Everything needs to be in C++, no BPs.
