Hello there! I wonder how to make scrollBar for a dx list. Have seen a lot of different tutorials but none of them helped me. Seems like I'm too dumb to understand it ?
Here is how my code currently looks like:

Spoiler 

local screenW, screenH = guiGetScreenSize()
local maxRows = 15
local openPanel = true

local items = {
	{"1",2000, 1},
	{"2",2000, 1},
	{"3",2000, 1},
	{"4",2000, 1},
	{"5",2000, 1},
	{"6",2000, 1},
	{"7",2000, 1},
	{"8",2000, 1},
	{"9",2000, 1},
	{"10",2000, 1},
	{"11",2000, 1},
	{"12",2000, 1},
	{"13",2000, 1},
	{"14",2000, 1},
	{"15",2000, 1},
	{"16",2000, 1},
	{"17",2000, 1},
	{"18",2000, 1},
	{"19",2000, 1},
	{"20",2000, 1},
	{"21",2000, 1},
	{"22",2000, 1},
	{"23",2000, 1},
	{"24",2000, 1},
	{"25",2000, 1},
}

if openPanel == true then
	addEventHandler("onClientRender", root,
    function()
        dxDrawRectangle(screenW * 0.2516, screenH * 0.2843, screenW * 0.4974, screenH * 0.4352, tocolor(1, 2, 3, 147), false)

Your mathematics has to be at a more advanced level. Have you ever considered to use stuff that already exist?
