KgPanels and Chat Fading

[Monk1nr]

I am sure someone has an answer for me, but I have looked for quite a while and found nothing.

Here is my problem: I have a panel that is parented and anchored to my Chatter chat frame and that is working fine. What I would like, however is that when chatter fades all the way out, I want my panel to do the same. I am assuming it stays because Chatter does not really go away but merely has no text visible.

What script can I add to the panel to have it disappear when Chatter does?

Thanks in advance and I apologize if this has been asked before.

Dang. 31 views and no reply. Has no one figured this out? There has to be a way to check if something is being shown on the chat frame.

Does anyone know?

I'm needing this, too. Trying to make the panel that is parented to one of my chat boxes fade when the text fades.

Found this script from Real on the interwebz, but it's not working so I'm thinking it's too old:

local kgp = self;
 local fadetime = 0.3;
 ChatFrame5:HookScript("OnShow", function(self)
 UIFrameFadeIn(kgp, fadetime, kgp:GetAlpha(), 1);
 end)

 ChatFrame5:HookScript("OnHide", function(self)
 UIFrameFadeOut(kgp, fadetime, kgp:GetAlpha(), 0.5);
 end)

Help??

Do you want the panel to hide when the text in the chat frame hides? Or when all the objects of the chat frame hide (tabs, background, etc)?

The fading out of the chat text is a function of Blizzard's widget, each line can have a different alpha value, so you would need to decide how to handle that.

Here is an example that gets the text with the maximum alpha:

function GetChatAlpha(frame)
    if frame == nil then return end
        
    local lines = { frame:GetRegions() }

    local maxAlpha = 0
    for i=#lines, 1, -1 do
        if lines[i]:GetObjectType() == "FontString" then
            maxAlpha = math.max(maxAlpha, lines[i]:GetAlpha())
        end
    end

    return maxAlpha
end

You can test it like

/script print(GetChatAlpha(ChatFrame1))

wait for the text to fade then run the same script to see it goes to 0.

This only works for visible chatframes though. Text on frames that arent visible doesn't get faded out until the frame is made visible again.

Ah, thanks for the replies!

I want the panel to fade when the text itself completely fades away, leaving an empty chat frame; mine don't disappear 100% but they do fade a lot (see 4 chat frames in lower left corner, one has the kgpanel missing to demonstrate the end result of fading):



So if I know the alpha value of the chat, then what Sylv? Sorry, I'm not good on writing scripts, not at all.

[sylvanaar]

Well then you know when it has beed faded out (alpha = 0)

You would need to write an onupdate to poll it though.

I don't know much about KgPanels, maybe someone else could help you integrate it.
