== Arguments ==

; arg1 : the new horizontal (x) position of the cursor in the edit box (the first column being 0, increasing to the right)
; arg2 : the new vertical (y) position of the cursor in the edit box (the first line being 0, DEcreasing downwards)
; arg3 : unknown
; arg4 : the height of one line

<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
