I'm trying to see if there are any other solutions for displaying a pop up message box other than message("xxx"). This addon displays a message box if you do not have any favorite mounts selected. I know favorite mounts are usually across characters, but I use an addon that lets me select favorites per character. Here is the code, any suggestions are appreciated.

Code:

--Addon will check to see if you have a favorite mount and remind you if you do not.



local JWNumMounts =  C_MountJournal.GetNumMounts();

local JWFav = 0

local JWNoFav = CreateFrame("Frame", "JWNoFav", UIParent)



JWNoFav:RegisterEvent("PLAYER_ENTERING_WORLD")



local function eventHandler(self, event, ...)

        for i = 1, JWNumMounts do

                if C_MountJournal.GetIsFavorite(i) then

                        JWFav = JWFav + 1

                end

        end

        if JWFav == 0 then

                message("You do not have any mounts selected as a favorite.")

        end

end



JWNoFav:SetScript("OnEvent", eventHandler)

You can create any frame you want to "popup/show()" your messages

Lua Code:

local function ShowMessage(text)
    if not JDoubleU00MessageBox then
        local f = CreateFrame("Frame", "JDoubleU00MessageBox", UIParent)
        --- Whatever your heart desires to see any messages plus a close (hide) button
        function f:SetText(text)
             -- Depends on your frame setup above how the text is "set"
        end
    end
    JDoubleU00MessageBox:SetText(text)
    if not JDoubleU00MessageBox:IsShown() then
        JDoubleU00MessageBox:Show()
    end
end
if JWFav == 0 then
    ShowMessage("You do not have any mounts selected as a favorite.")
end

Thanks, this helps, but I must be doing something wrong with either frame creation or setting the text. I've merged my code with yours and nothing is displayed. I did make sure that I do not have any favorite mounts and I had print statements to show me if I had logic errors. No errors. I am confused on the SetText function. Why call a function and isn't there a potential conflict with the name of the function? What am I missing?

            function f:SetText(text)

                        -- Depends on your frame setup above how the text is "set"

Your message FontString has a SetPoint of CENTER to your event frame which has no SetPoint. The SetText function was an "if needed" thought you might add to JDoubleU00MessageBox frame to set the text of its child FontString.

Lua Code:

--Addon will check to see if you have a favorite mount and remind you if you do not.
 
local JWNumMounts =  C_MountJournal.GetNumMounts();
local JWFav = 0
JWNoFav = CreateFrame("Frame", "JWNoFav", UIParent)
JWNoFavFont = [[Interface\Addons\SharedMedia_MyMedia\font\Lato-Regular.ttf]]
JWNoFavFontSize = 18
JWNoFavFontFlags = "NONE"
 
local function ShowMessage(text)
    if not JDoubleU00MessageBox then
        local f = CreateFrame("Frame", "JDoubleU00MessageBox", UIParent)
            --- Whatever your heart desires to see any messages plus a close (hide) button
        f:SetFrameStrata("BACKGROUND")
        f:SetHeight(64)
        f:SetBackdrop({bgFile = "Interface/Tooltips/UI-Tooltip-Background", edgeFile="Interface/Tooltips/UI-Tooltip-Border", tile = true, tileSize = 8, insets = {left = 8, right = 8, top = 8, bottom = 8},})
        f:SetBackdropColor(0.5, 1, 0.5)
        f:SetBackdropBorderColor(1, 0, 0)
        f:SetPoint("CENTER")
 
        f.Close = CreateFrame("Button", nil, f, "UIPanelButtonTemplate")
        f.Close:SetSize(24, 24)
        f.Close:SetPoint("TOPRIGHT", -8, -8)
        f.Close:SetText("X")
        f.Close:SetScript("OnClick", function(self) self:GetParent():Hide() end)
 
        f.nfText = f:CreateFontString("$parentText", "OVERLAY", "NumberFontNormal") --GameFontNormal
        f.nfText:SetFont(JWNoFavFont, JWNoFavFontSize, JWNoFavFontFlags)
        f.nfText:SetPoint("CENTER")
    end
    JDoubleU00MessageBox.nfText:SetText(text)
    JDoubleU00MessageBox:SetWidth(JDoubleU00MessageBox.nfText:GetWidth() + 50)
    if not JDoubleU00MessageBox:IsShown() then
        JDoubleU00MessageBox:Show()
    end
end
 
local function eventHandler(self, event, ...)
    for i = 1, JWNumMounts do
        if C_MountJournal.GetIsFavorite(i) then
            JWFav = JWFav + 1
        end
    end
    if JWFav == 0 then
        ShowMessage("You do not have any mounts selected as a favorite.")
    end
end
 
JWNoFav:RegisterEvent("PLAYER_ENTERING_WORLD")
JWNoFav:SetScript("OnEvent", eventHandler)

Thank you so much, it worked perfectly! I learned a few things that I will need to remember for future frame creating. I had been trying to figure out the method you used for setting the message box width. I can use that in a couple of other addons of mine.
