Check if ScrollBar of a ScrollBox is visible

reiniii.gg · February 20, 2020, 6:17am

I have some buttons that I want to show/hide depending if the scrollbar of my UScrollBox is visible. I’ve tried binding the visibility of the buttons to UScrollBox->ScrollBarVisbility but its value is always ‘Visible’ even if the scrollbar is indeed hidden. Is there any other way to check if the visibility of the scrollbar?

Simply whenever you set it not visible set those not visible aswell… IDK What are you trying exaclty sorry. I hope it helps.

@**reiniii.gg **Pretty sure I’m trying to do the same thing as you. The scrollbox’s GetScrollOffsetOfEnd will be 0 if it can’t be scrolled (which is when the scrollbar would also disappear).

I haven’t found a great event to work with to know when to trigger the check though. Polling it on tick is so far the best I’ve found, for better or worse.
