Yes, but written that way it would toggle the CVar based on whether or not you were in combat, not whether or not you were in a raid. Also, since you still check for raid status, whatever state you were in when you left a raid group -- quest info shown, or not shown -- would "stick" until the next time you entered or left combat after joining another raid group, which probably isn't the intention.

My code start from the info that you should be not in combat to set the CVAR and on my idea that you can't be kicked or leave the group in combat (WRONG


So now, reading again (and understanding better) your code I think it is a so simple and elegant solution.

local f = CreateFrame("Frame")
f:RegisterEvent("GROUP_ROSTER_UPDATE")
f:SetScript("OnEvent", function(self, event)
    SetCVar("showQuestTrackingTooltips", IsInRaid() and 0 or 1)
end)

Thanks (as usual)
