Thanks Phanx and Seerah for answers.

I have checked the Phanx code and it works nicely (the 2nd bigger one) but I think I'll leave the button as they are now, because it doesn't work with all buttons templates or with no template at all.
Btw finally I understood how it works. As usual it was a little bit more complicated then I thought :-)

Ok. In the meantime I have solved also the question nr.3 I asked:

3) Is possible to have the scrollframe "bordered" like the input box below ?

I checked the rtest by Zork (thanks) and I have discovered the Templates world :-)

Now I am investigating why the scrollframe works nicely in the test addon I make following the Lombra suggestion/code posted at the beginning of this thread, while it have the problem I have pointed out with the picture when I build the scrollist array from my data.

If I used something like:

RemGankLS = { "qui", "quo", "qua", etc etc }

It works as expected and I don't have the iussue shown in the picture.

But I have a table in this way saved:

RemGankDB = {
    ["qui"] = {
        ["name"] = "qui",
        ["date"] = "06.01.2013 19:28:24",
        ["desc"] = "generic ganker",
        ["lastloc"] = "Massiccio del Kun-Lai/Presidio del Fuoco Yongqi",
        ["nrkill"] = 1,
    },
    ["quo"] = {
        ["name"] = "quo",
        ["date"] = "03.02.2013 17:35:10",
        ["desc"] = "generic ganker",
        ["lastloc"] = "Vallata dell'Eterna Primavera/Volta di Guo-Lai",
        ["nrkill"] = 1,
    },
    ["qua"] = {
        ["name"] = "qua",
        ["date"] = "09.02.2013 10:57:16",
        ["desc"] = "generic ganker",
        ["lastloc"] = "Valle dei Quattro Venti/Mezzocolle",
        ["nrkill"] = 1,
    },
       
      --- etc etc 
}

So to use a number reference to the records for the scrollframe I was not able to find a better solution of doing something like this:

function RemGank_DB_Dump()
    RemGankLS = {}
    for name in pairs(RemGankDB) do     
        name = name:lower()
        if RemGankDB[name]["name"] then 
            table.insert(RemGankLS, RemGankDB[name]["name"])
        end
    end
    -- Sort the list alphabetically
    table.sort(RemGankLS)   
end

And everything works but the slider have the problem I show.

Someone have an idea on why it happens or if the problem is the dumping how to call this code :

function RemGank_ListFrame_Update(self)
    local numItems = #RemGankLS
    FauxScrollFrame_Update(self, numItems, NUM_BUTTONS, BUTTON_HEIGHT)
    local offset = FauxScrollFrame_GetOffset(self)
    for line = 1, NUM_BUTTONS do
        local lineplusoffset = line + offset
        local button = buttons[line]
        if lineplusoffset <= numItems then
            button:SetText(RemGankLS[lineplusoffset])
            button:Show()
        else
            button:Hide()
        end
    end
end
 
-- [...]
 
for i = 1, NUM_BUTTONS do
    local button = CreateFrame("Button", nil, scrollFrame:GetParent(), "UIPanelButtonTemplate") 
    if i == 1 then
        button:SetPoint("TOP", scrollFrame)
    else
        button:SetPoint("TOP", buttons[i - 1], "BOTTOM")
    end
    button:SetNormalFontObject("GameFontNormal")
    button:SetSize(BUTTON_WIDTH, BUTTON_HEIGHT)
    button:SetText(RemGankLS[i])
    button:SetScript("OnClick", function(self) 
        RemGank_Input_eb2:SetText(button:GetText())
        info_name:SetText(button:GetText())
        info_desc:SetText(RemGankDB[button:GetText()]["desc"])
        info_loc_title:SetText("Last Kill:")
        info_date:SetText(RemGankDB[button:GetText()]["date"])
        info_loc:SetText(RemGankDB[button:GetText()]["lastloc"])
        info_kills_title:SetText("Tot.Kills:")
        info_kills:SetText(RemGankDB[button:GetText()]["nrkill"])
    end)
    buttons[i] = button
end

without the need of dumping the first table RemGankDB (referenced by name) to RemGankLS (indexed by numbers) ?

Thanks for patience and sorry again about all these questions.
