By default TArray grows and reallocates memory as items are added, according to an allocation policy. Adding elements to TArray is easy, which is part of what makes TArray so convenient. Add and Emplace functions can create new elements at the end of the array: TArray<FString> StrArr; StrArr.Add (TEXT("Hello")); StrArr.Emplace(TEXT("World")); // StrArr == ["Hello","World"] The array's allocator provides memory as needed when new elements are added to the array. Answer (1 of 4): Qt Creator is just IDE, it's incapable of doing any magic. Hence simple answer is: You can't. I don't have enough insight into your console application, but most of cases it's utter nonsense in attempt to turn command line tool into GUI applications. If your application already.GNU License 🤦‍♂️ Some of the methods in that helper are obsolete since XE7 because we have Insert, Add, Delete for dynamic arrays.
