Updating tooltip while tooltip is still active.

ok i am still a bit on the newb side, so im asking this question to see if this is something that is even possible. i can show a tiny snippet of my code to see what im tying to accomplish.

Lua Code:

local malObject = {
    type = "launcher",
    icon = "Interface\\Addons\\MaggzAutoLog\\disabled",
    label = "MaggzAutoLog",
    OnClick = function(self, button)
        if button == "RightButton" then
            LOGSTATE()
        end
        if button == "LeftButton" then
            if LoggingCombat() then
                disablelogging()
            else
                enablelogging()
            end
        end
    end,
    OnTooltipShow = function(tooltip)
    tooltip:AddLine("|cff00FF00MaggzAutoLog|r");
    tooltip:AddLine("hold left mouse button to drag");
    tooltip:AddLine("right click to enable/disable logging");
    if LoggingCombat() then
        tooltip:AddLine("Logging |cff00FF00Enabled|r");
    else
        tooltip:AddLine("Logging |cffFF0000Disabled|r");
    end
end,
};

i used the minimap button creation tips i had found thru searching and atm it all works well for me, with one minor issue, i cant seem to find any documentation anywhere about how to update that last tooltip:AddLine("information here"); while the tooltip is still open and displaying. If this is something that cant be currently done that would be nice to know as well.

What my main goal is here is to add in some displayfunctionality to my addon to show current state of your combat logging. i do believe i have accomplished that with just this one issue perplexing me. Only reason i wanted to add this sort of ability is because i used loggerhead for a long while and liked how it functioned, however its not been updated for atleast last 2 patches. I know my addon is going to be NO WHERE near the functionality as that one.

If i need to post my entire LUA file here please let me know as well, i just wanted to atleast get some inut as to what im looking to do is capable

You can call GameTooltip:AddLine() whenever you want and add text just fine. What you're missing is that you should always call GameTooltip:Show() after adding to it in order to refresh the tooltip, make sure everything is shown that you want, and to make the GameTooltip resize itself to fit your new lines.

i can get my tooltip to display perfectly with one exception, i would like for it to reset when i right click to update the tooltip info without having to move my mouse off the tooltip and rehover. i tried adding what your proposing and it isnt working. i tried adding just the GameTooltip:Show() in under my right onclick events and it just doesnt reset the tooltip unless i rehover over the tooltip. Am i missing something in my understanding? or can you not refresh a tooltip on a mouseclick?

++++++
sorry i passed my event in an incorrect variable i had similar to the enable and disable logging functions. it adds a line just fine, however if i just keep clicking i can end up with 500 lines of tooltips. Is there a way to simply overwrite an existing ine in your tooltip?

AHHH i did figure it out, sorry to have bugged ya with the reply, it took me some figuring out to call a GameTooltip:ClearLines() first then append all the tooltips i want added back after that call. Tho it would be much nicer if there was a way to just remove line 3 and replace it with a new line. Sorry to seem such a newb and TY for your help, you pointed me in the right direction and i definatly appreciate that. Guess now that leaves my TODO list at figuring out how to save the position of my minimap icon properly lol thats another day tho.

Just change the text of line three then.

GameTooltipTextLeft3:SetText("new text!")

Generally, if you have access to the function that creates the tooltip in the first place, you can just call it again. It shouldn't matter if the tooltip is still showing.

If you want your addon to work together with other addons which also modifies the tooltips,
you might need to be a little more sophisticated around how you modify your lines.
You will not always know which lines are yours. And clearing the entire tooltip will end up clearing more than you want too...

Here is the approach I ended up using:

Code:

local cachedUnit = nil

function OnTooltipSetUnit()
	--Figure out if we are reading data from mouseover or target
	local unit = "mouseover"
	if (not UnitExists(unit)) then
		unit = "target"
	end

	--Cache unit so that we can run it again later with the same unit
	cachedUnit = unit
	AppendCustomTooltipLines()
end

function AppendCustomTooltipLines()
	--Add custom lines here with custom color
	local r = 1
	local g = 1
	local b = 1
	GameTooltip:AddLine("Custom text here...", r, g, b)
end

function UpdateTooltip()
	if cachedUnit == nil then return end

	--Makes sure custom tooltip lines are cleared
	GameTooltip:SetUnit(cachedUnit)
end

GameTooltip:HookScript("OnTooltipSetUnit", OnTooltipSetUnit)

You may then call UpdateTooltip() wherever, when you know there is new data to apply.
