Chat Options

[Iezabel]

I know there are a ton of Chat Addons out there already. But I want to go ahead and create my own. So far things are working well with it but I am running into an issue. I want to have windows switch out based on if you are in a group or not. Is this possible or would the easiest way be to have buttons with the OnPush event to show/hide the windows?

You can listen for GROUP_ROSTER_UPDATE events. Keep track of the group state in a variable outside of your event handler. When the group changes, figure out if your actual group state changed (the event fires for all kinds of group related reasons, not just joining/leaving one) and if it did, make the appropriate changes in your addon.

local inGroup

local frame = CreateFrame("Frame")
frame:RegisterEvent("GROUP_ROSTER_UPDATE")
frame:SetScript("OnEvent", function(self, event)
     local inGroupNow = IsInGroup()
     if inGroupNow == inGroup then return end -- nothing changed
     inGroup = inGroupNow -- store the new state
     -- make your changes here
end)

You can also get more detailed about tracking the group type/size (eg. to use different layouts in a raid group vs a battleground vs a 5-man, etc.). See Grid's code for an example.
