flickerstreak@63 2 ReAction.lua
flickerstreak@63 3
flickerstreak@63 4 The ReAction core manages 4 collections:
flickerstreak@63 5 - modules (via AceAddon)
flickerstreak@63 6 - bars
flickerstreak@63 7 - options
flickerstreak@63 8 - bar-type constructors
flickerstreak@63 9
flickerstreak@63 10 and publishes events when those collections change. It also implements a single property, 'config mode',
flickerstreak@63 11 and has a couple convenience methods which drill down to particular modules.
flickerstreak@63 12
flickerstreak@63 13 Most of the "real work" of the addon happens in Bar.lua and the various modules.
flickerstreak@63 14
flickerstreak@63 15 Events (with handler arguments):
flickerstreak@63 16 --------------------------------
flickerstreak@63 17 "OnCreateBar" (bar, name) : after a bar object is created
flickerstreak@63 18 "OnDestroyBar" (bar, name) : before a bar object is destroyed
flickerstreak@63 19 "OnEraseBar" (bar, name) : before a bar config is removed from the profile db
flickerstreak@63 20 "OnRenameBar" (bar, oldname, newname) : after a bar is renamed
flickerstreak@63 21 "OnRefreshBar" (bar, name) : after a bar's state has been updated
flickerstreak@63 22 "OnOptionsRefreshed" () : after the global options tree is refreshed
flickerstreak@63 23 "OnConfigModeChanged" (mode) : after the config mode is changed
flickerstreak@63 24 "OnBarOptionGeneratorRegistered" (module, function) : after an options generator function is registered
flickerstreak@63 25
flickerstreak@63 26 ReAction is also an AceAddon-3.0 and contains an AceDB-3.0, which in turn publish more events.
