Seeing the number of members in a structure array item isn't overly helpful. Thankfully, when you're dealing with them in C++, there is one easy solution!
When declaring the UPROPERTY for the structure array, you can specify a TitleProperty metadata using the properties from the struct.
For example, using the ItemName property as the TitleProperty will result in the structure displaying that value.
UPROPERTY(EditAnywhere, Meta = (TitleProperty = "ItemName"))TArray<FItemData> Items;
Using multiple structure properties as values can be achieved by surround the property with curly brackets.
UPROPERTY(EditAnywhere, Meta = (TitleProperty = "{ItemName} {ItemQuality}"))TArray<FItemData> Items;
Full Example
/** The information of the item. */USTRUCT(BlueprintType)struct FItemData{ GENERATED_BODY(); /** The name of the item. */ UPROPERTY(EditAnywhere, BlueprintReadWrite) FName ItemName; /** The description of the item. */ UPROPERTY(EditAnywhere, BlueprintReadWrite) FText ItemDescription; /** The quality of the item. */ UPROPERTY(EditAnywhere, BlueprintReadWrite) FText ItemQuality; //..};/** A Data Asset that holds the array */UCLASS(ClassGroup=(Custom), meta=(BlueprintSpawnableComponent))class UInventoryManager : public UActorComponent{ GENERATED_BODY() /** The items contained in the inventory. */ UPROPERTY(EditAnywhere, Meta = (TitleProperty = "{ItemName} {ItemQuality}")) TArray<FItemData> Items; //..};
