UScrollBox::AlwaysShowScrollbarTrack has its own getter/setter function (SetAlwaysShowScrollbarTrack/IsAlwaysShowScrollbarTrack).
In another property for UScrollBox::bAllowRightClickDragScrolling, the getter/setter function incorrectly references AlwaysShowScrollbarTrack.
Suggested code:
void UScrollBox::SetAllowRightClickDragScrolling(bool NewAlwaysShowScrollbarTrack)
{
#if 0
AlwaysShowScrollbarTrack = NewAlwaysShowScrollbarTrack;
#else
bAllowRightClickDragScrolling = NewAlwaysShowScrollbarTrack;
#endif
if (MyScrollBox)
{
#if 0
MyScrollBox->SetScrollBarTrackAlwaysVisible(AlwaysShowScrollbarTrack);
#else
MyScrollBox->SetScrollBarTrackAlwaysVisible(bAllowRightClickDragScrolling );
#endif
}
}
bool UScrollBox::IsAllowRightClickDragScrolling() const
{
#if 0
return AlwaysShowScrollbarTrack;
#else
return bAllowsRightClickDragScrolling;
#endif
}
When bAllowRightClickDragScrolling=false and AlwaysShowScrollbarTrack=true in Scrollbar, UScrollBox::IsAllowRightClickDragScrolling() returns True. Here we expect False.
