Need help with a Scrollbar!

[Ledii]

Hey, so I wanted a scrollbar for a list I'm making, and as far as I could figure out by many hours at google. The "FauxScrollFrameTemplate" was the easies way to go?

Anyways, I have set it up where I want, the objects (buttons) pop up where the should, all good. But the problem I'm having is that I can't get to run any update events becuase my scollbar is all gray and seems to be in a state of being 100% scrolled in both directions. Therefor I can't grab it and test out the other stuff.

What do I do to make it draggable?

CreateFrame("ScrollFrame", "Critz_Scroll", Critz_Main, "FauxScrollFrameTemplate")
Critz_Scroll:SetSize(BUTTON_WIDTH, BUTTON_HEIGHT * NUM_BUTTONS)
Critz_Scroll:SetPoint("RIGHT", Critz_Main, "RIGHT", -BUTTON_HEIGHT * 2, 0)
Critz_Scroll:SetScript("OnVerticalScroll", function(self, offset)
	FauxScrollFrame_OnVerticalScroll(self, offset, BUTTON_HEIGHT, Scroll_Update)
end)
Critz_Scroll:Show()

Afaik the FauxScrollFrameTemplates is no actual scrolling frame. It just removes/appends rows based on the viewable area.

I suggest using the UIPanelScrollFrameTemplate.

--create a scrollframe on parent Critz_Main
    local scrollFrame = CreateFrame("ScrollFrame", "$parentScrollFrame", Critz_Main, "UIPanelScrollFrameTemplate")
    scrollFrame:SetPoint("TOPLEFT") --topleft point of Critz_Main
    scrollFrame:SetPoint("BOTTOMRIGHT",-27,0) --bottomright point -27 of Critz_Main
 
    --add a scrollbar background
    --[[
    local tex = scrollFrame:CreateTexture(nil,"BACKGROUND",nil,-6)
    tex:SetPoint("TOP",scrollFrame)
    tex:SetPoint("RIGHT",scrollFrame,25.5,0)
    tex:SetPoint("BOTTOM",scrollFrame)
    tex:SetWidth(26)
    tex:SetTexture("Interface\\PaperDollInfoFrame\\UI-Character-ScrollBar")
    tex:SetTexCoord(0,0.45,0.1640625,1)
    tex:SetAlpha(0.5)
    ]]
    
    --the scrollchild
    local scrollChild = CreateFrame("Frame",nil,scrollFrame)
    local w,h = scrollFrame:GetSize()
    scrollChild:SetSize(w,h)
    scrollFrame:SetScrollChild(scrollChild)
 
    --put as many buttons/frames into the scrollchild as you like
    local button = CreateFrame("Button", "MyShinyButton1", scrollChild, "UIPanelButtonTemplate")
    button.text = _G[button:GetName().."Text"]
    button.text:SetText("Hello World")
    button:SetWidth(button.text:GetStringWidth()+20)
    button:SetHeight(button.text:GetStringHeight()+12)
    button:SetPoint("TOPLEFT",0,0)

Ah, why does it display a scrollbar if it isn't supposed to handle it?

Also, I find it very hard to learn what all the code for wow addons actually does, because there are very poor documentation on which calls are made and how everything connect together.

I would like to connect what I got for now to a scroller so that I can start testing as soon as possible,
will the scroller method you reccomended to that or would that be building it from scratch again? Tutorials sure don't help at all. Only debug info will do what I need sadly (which ofthen take ages).

Because it's a Faux (From the Old French for false) ScrollFrame. It acts like a scrollframe, but what it's actually doing is replacing every line with what would be at the scrollbars offset.

Hi,
I also had a lot of difficulties trying to implement correctly a scrollbar some time ago and if you need some more inputs you can check this thread too:
