Fix over scroll

[Walkerbo]

Hi all

I have a bear-bones scroll set up that is over-scrolling past the last data button.


Here is my code:

local function updateScrollFrame()
    FauxScrollFrame_Update(
        TestScrollFrame,
        #TestData,
        7,
        20
    )
    for index = 1, 7 do
        local offset = index + FauxScrollFrame_GetOffset(TestScrollFrame)
        local button = TestScrollFrame.buttons[index]
        button:SetNormalFontObject(NumberFontNormalLargeYellow)
        button:SetHighlightFontObject(NumberFontNormalLargeYellow)
        button.index = offset
        if offset <= #TestData then
            button:SetText(TestData[offset])
            button:Show()
        else
            button:Hide()
        end
    end
end
 
local TestScrollFrame = CreateFrame("Frame", "TestScrollFrame", TestInterfaceFrame, "ChatConfigBoxTemplate")
TestScrollFrame:SetSize(500, 150)
TestScrollFrame:SetPoint("TOPLEFT", TestInterfaceFrame, "BOTTOMLEFT")
 
local TestScrollFrame =
    CreateFrame("ScrollFrame", "TestScrollFrame", TestScrollFrame, "FauxScrollFrameTemplate")
TestScrollFrame:SetPoint("TOPLEFT", 0, -8)
TestScrollFrame:SetPoint("BOTTOMRIGHT", -30, 8)
TestScrollFrame:SetScript(
    "OnVerticalScroll",
    function(self, offset)
        FauxScrollFrame_OnVerticalScroll(self, offset, 7, updateScrollFrame)
    end
)
 
TestScrollFrame.buttons = {}
for index = 1, 7 do
    TestScrollFrame.buttons[index] =
        CreateFrame("Button", "$parentbtn" .. index, TestScrollFrame, "OptionsListButtonTemplate")
    local button = TestScrollFrame.buttons[index]
    button:SetSize(500, 20)
    button:SetPoint("TOPLEFT", 8, -(index - 1) * 20 - 8)
    button:SetScript(
        "OnClick",
        function(self, button)
            if button == "RightButton" then
                print(TestData, self.index)
                updateScrollFrame()
            end
        end
    )
end

How do I solve the over-scrolling issue?
