This is a variation of the system I used in TasAbilityFieldTooltip to know that a CommandButton is hovered. It allows to add/Remove callbacks to the hover feature and have many of them.
Changelog:
V1.1 API functions became a table member of HoverOriginButton
Lua:
--[[ HoverOriginButton V1.1 by Tasyen
This System gives a easy way setup callbacks when a Command/Item 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(forCommandButton, everyTime, action)
forCommandButton (true) add to commandButton Actions
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(action)
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
