--[[ HoverOriginButton V1.3 by Tasyen
This System gives a easy way setup callbacks when a originframe Button is hovered. It uses Tooltips hence the executed callbacks are async.
I created this because one can do this Tooltip approach to know hovering only once per map so that systems don't have to fight over that feature but use it.
function HoverOriginButton.Add(originframeType, function(buttonIndex) end[, everyTime])
originframeType ORIGIN_FRAME_COMMAND_BUTTON or ORIGIN_FRAME_HERO_BUTTON ...
everyTime (false) only happens when the current Frame was not hovered lastTime.
action the callback
function(buttonIndex)
yourCode
yourCode
end
returns the new objects can be used for HoverOriginButton.Remove
function HoverOriginButton.AddClose(function() end)
add a callback that happens when the user stops hoveringer a Command/Item Button, async.
function()
yourCode
yourCode
end
function HoverOriginButton.Remove(object)
removes the table from the callback List
