Example[edit]
Say we have a plain textbox inside a scrollframe (inside UIPanelScrollFrameTemplate; as the only child-element, etc.), the following code will automatically move scrollframe viewport so that the cursor is inside it. (The ScrollingEdit_OnUpdate() function in UIPanelTemplates.lua does something akin to this also.)
<OnCursorChanged> local vs = this:GetParent():GetVerticalScroll(); local h = this:GetParent():GetHeight(); if vs+arg2 > 0 or 0 > vs+arg2-arg4+h then this:GetParent():SetVerticalScroll(arg2*-1); end </OnCursorChanged>
