Runebar and combobar

[yj589794]

The standard cpoints element does not support pre and post update routines.

You would need to override the standard update routine to add them in.

local comboUpdate = function(self, event, unit)
	-- copied from standard update routine
	if(unit == 'pet') then return end

	local cp
	if(UnitExists'vehicle') then
		cp = GetComboPoints('vehicle', 'target')
	else
		cp = GetComboPoints('player', 'target')
	end

	local cpoints = self.CPoints
	for i=1, MAX_COMBO_POINTS do
		if(i <= cp) then
			cpoints[i]:Show()
		else
			cpoints[i]:Hide()
		end
	end

	-- add postupdate support
	if cpoints.PostUpdate then cpoints.PostUpdate(self) end
end

local comboPostUpdate = function(self)
	-- add code to check if combo elements are shown and move aura buttons
end

local style = function(self, unit)
	-- define your combo points element
	local cpoints = ...
	...

	cpoints.Update = comboUpdate
	cpoints.PostUpdate = comboPostUpdate

	self.CPoints = cpoints
end
