The Viewport is buried down in ListBox, so we have no access to control the visibilities of ScrollBars at TableListBox. Can’t we have control on these?
and if I directly change isVisible, no problem?
Why would you want to make it invisible? How would people scroll it if it’s too big?
They can still use scroll keys, but they want to fit everything in a screen, thus I have to give them options for turning everything off, including header.
You’d need to open up a way of accessing the list’s viewport, to get to the Viewport::setScrollbarsShown method…
