RequestVerticalScrollbar() as ScrollBarParameters
Returns

Remarks
When giving scrollbar to the TreeView then just place it off screen and set its visible property to false.
Then the event would be like this:
Function RequestVerticalScrollbar() Handles RequestVerticalScrollbar as ScrollBar
// This event is only used for Linux to supply a Xojo scroll bar because
// we cannot embed scroll bar at all on Linux.
return ScrollbarForLinux
End Function
