How do you get the value from an UNameProperty

Development Programming & Scripting

I need to monitor the change of a FName property. Implementing the PreEditChange() and PostEditChangeProperty() methods was easy enough but now I am stuck.
I cast the UProperty to UNameProperty but GetPropertyValue() or GetPropertyValue_InContainer() returns nothing useful.

This works for me:

void ACGALBox::PostEditChangeProperty(FPropertyChangedEvent& e) {
    FName propertyName = (e.Property != nullptr) ? e.Property->GetFName() : NAME_None;

    if (propertyName == GET_MEMBER_NAME_CHECKED(ACGALBox, meshWidth)) {
        UFloatProperty* fp = static_cast<UFloatProperty*>(e.Property);
        float* val = fp->GetPropertyValuePtr(&meshWidth);
        UE_LOG(LogTemp, Warning, TEXT("%0.3f"), *val);
    }

    Super::PostEditChangeProperty(e);
}

Where my meshWidth variable declaration looks like this:

private:
    UPROPERTY(EditAnywhere, meta=(AllowPrivateAccess="true"))
    float meshWidth;

And I set its default value in the constructor like this:

ACGALBox::ACGALBox() :
meshWidth(200.0f)
{
    // Rest of ctor here.
}
