How do you find out which option was changed in the editor from code?

Development Programming & Scripting
1

If I define some variables in code like this

UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "Volume Options", meta = (DisplayName = "Volume Size 1"))
int32 VolumeSize;
UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "Volume Options", meta = (DisplayName = "Volume Size 2"))
int32 VolumeSize2;

I know I can pickup any change in the editor with my components OnRegister callback.
But Is there a function I can use that tells which value was changed?

I think you searching for PostEditChangeProperty?

That is what I was looking for exactly. Thank you.
