oUF MainTanks (Ora2 & Blizzard)

[Silberbüchse]

Hi,
iam looking for a ouf code snippet that show oRA2 & Blizzards MTs & MTTs.
Actually iam a ouf_shestak user. Here's the code from his layout:

if not unitframe_hide_raid then
	--[[local tank = oUF:Spawn("header", "oUF_MainTank")
	tank:SetManyAttributes("showRaid", true, "groupFilter", "MAINTANK", "yOffset", -5)
	tank:SetPoint("BOTTOMRIGHT", "oUF_Target", "LEFT", unitframe_tank_position_x, unitframe_tank_position_y)
	tank:SetAttribute("template", "oUF_MainTank")
	tank:Show()]]
	local tank = oUF:Spawn('header', 'oUF_MainTank')
		tank:SetPoint("BOTTOMRIGHT", "oUF_Target", "LEFT", unitframe_tank_position_x, unitframe_tank_position_y)
		tank:SetManyAttributes("showRaid", true, "groupFilter", "MAINTANK", "yOffset", -5)
	if oRA3 and not select(2,IsInInstance()) == "pvp" and not select(2,IsInInstance()) == "arena" then
		tank:SetAttribute(
			"initial-unitWatch", true,
			"nameList", table.concat(oRA3:GetSortedTanks(), ",")
		)
		local tankhandler = CreateFrame('Frame')
		function tankhandler:OnEvent()
			if(InCombatLockdown()) then
				self:RegisterEvent('PLAYER_REGEN_ENABLED')
			else
				self:UnregisterEvent('PLAYER_REGEN_ENABLED')
					if self.tanks then
						tank:SetAttribute(
							"nameList", table.concat(self.tanks, ","))
						self.tanks = nil
					end
			end
		end
		function tankhandler:OnTanksUpdated(event, tanks)
			self.tanks = tanks
			self:OnEvent()
		end
		tankhandler:SetScript('OnEvent', tankhandler.OnEvent)
		oRA3.RegisterCallback(tankhandler, "OnTanksUpdated")
	else
		tank:SetAttribute("template", "oUF_MainTank")
	end
	tank:Show()
end
