Tooltip when hovering over an item.

local addonName, addon = ...
-- Define localization table for German language
local L = {
    [210714] = {
        ["name"] = "Abgesplitterter tödlicher Saphir", -- Translate item name
    },

-- Hooking into the default GameTooltip to add our custom text
local function AddTooltipInfo(tooltip)
    local _, itemLink = tooltip:GetItem()

        if itemId then
            -- Check if the item ID is in our localization table
            local localizedItem = L[itemId]
            if localizedItem then
                tooltip:AddLine(localizedItem["name"])
            end

Hi all. I need your help again.

Description of the problem: There is an item in the bag "Chipped Deadly Sapphire" (ID 210714). It is necessary that when you hover the mouse over it or on the object itself, an inscription appears. Or the inscription appeared in the tooltip above the item.

As it is now: The tooltip appears only if the item is “Linked” into the chat.

I tried all the options. But I still couldn’t solve this problem myself.

The item in the bag does NOT have a hint.


If you send a chat message with an item, there is a hint.


How to make sure that the item in the bag also has a hint?

It looks like you already have an addon installed that adds to the tooltip. Maybe how that works is interfering with what you are trying to do. Try without any other addons and just the one you are working on and see how it works then.

I was having this problem with my mageports addon, but my rewrite has removed the need for those changes.

There are many functions that call up the tooltip to show an item. Too many to make it feasible to hook each one individually. Instead, there are scripts/callbacks that fire depending on whether you're running the Classic or Retail client.



Classic:

GameTooltip:HookScript("OnTooltipSetItem",function(self)
    local name,itemlink=self:GetItem();
 
--  Do stuff
end);

Retail:

local function OnTooltipSetItem(self,itemlink)
--  Do Stuff
end
 
TooltipDataProcessor.AddTooltipPostCall(Enum.TooltipDataType.Item,function(self)
    local itemlink; do
        local tooltip_info=self:GetProcessingTooltipInfo();
        local tooltip_data=tooltip_info and tooltip_info.tooltipData;
        itemlink=tooltip_data and (tooltip_data.guid and C_Item.GetItemLinkByGUID(tooltip_data.guid) or tooltip_data.hyperlink);
    end
 
    if itemlink then OnTooltipSetItem(self,itemlink); end
end);
 
TooltipDataProcessor.AddTooltipPostCall(Enum.TooltipDataType.Macro,function(self)
    local itemlink; do
        local tooltip_info=self:GetProcessingTooltipInfo();
        if tooltip_info and tooltip_info.getterName=="GetAction" then
            itemlink=select(2,GetMacroItem(select(2,GetActionInfo(tooltip_info.getterArgs[1]))));
        end
    end
 
    if itemlink then OnTooltipSetItem(self,itemlink); end
end);
 
TooltipDataProcessor.AddTooltipPostCall(Enum.TooltipDataType.Toy,function(self)
    local itemlink; do
        local tooltip_info=self:GetProcessingTooltipInfo();
        local tooltip_data=tooltip_info and tooltip_info.tooltipData;
        itemlink=tooltip_data and C_ToyBox.GetToyLink(tooltip_data.id);
    end
 
    if itemlink then OnTooltipSetItem(self,itemlink); end
end);

Retail requires more processing of a few different TooltipData structures, all that will produce an item tooltip.

I disabled all addons, but the result is the same. I don’t know what to do anymore =(

Thanks it worked.
