[C++] Array modification callback

[Kroakie84]

Is there a way to set a callback for when an array is modified (insert/delete/modify element)

Wrap the array modification in functions that the delegate will also call, and perform all array operations through these functions.

Thanks for the reply! How do I hook it up so that the UI will call these function? I tried looking at he property specifiers page but don’t see anything that looks like it could do this.

I didn’t quite understand you.

Above I talked about something like this:

Sorry, should have been clearer. Let me give some background.

I’m creating a new manager class in C++. It has an array of some definitions. I want to have a callback so when user modifies the array or any of the elements I can do some processing.

Something like this

UPROPERTY()
TArray<FSomeSettings> Settings;

void OnSettingsChanged()
{
    // Do processing here
}

It seems you need this:

UObject::PostEditChangeProperty

Override this in the class you want to track.

Ahh that seems to be it! Thank you.
