32 Blizzard Events:
33 - UPDATE_MULTI_CAST_ACTIONBAR
34
35 Blizzard APIs:
36 - GetMultiCastBarOffset() : returns 6
37
38 - SetMultiCastSpell(actionID, spellID) (protected) OR
39 SetAttribute("type","multispell")
40 SetAttribute("action",actionID)
41 SetAttribute("spell",spellID)
42
43 note: multicast actionID page is NUM_ACTIONBAR_PAGES + GetMultiCastBarOffset(),
44 so that's action ID 132-144.
45
46 - spell1, spell2, spell3, ... = GetMultiCastTotemSpells(slot)
47 returns spellIDs for all known totems that fit that slot. This function is available in
48 the secure environment.
49
50 Blizzard textures:
51 All the textures for the multicast bar (arrows, empty-slot icons, etc) are part of a single
52 texture: each texture uses SetTexCoord() to display only a slice of the textures. I suppose
53 this is to slightly optimize texture load performance, but it makes the UI code more clumsy.
54
55 Each totem button and arrow has a colored border indicating its elemental type.
56
57 TODO:
58 - make whether to show the colored border configurable (looks really bad with ButtonFacade:Zoomed)
59 - apply ButtonFacade to the flyout buttons? Or at least zoom the textures slightly?
60 - use a multiplier with SetTexCoord on totem bar texture?
61
62 Design Notes:
63 - Only the header has a secure context. All other frames execute in its context.
64
65 - Each button is either type "spell" (summon/recall) or type "action" (totem action IDs are
66 GetBonusBarOffset()=6, 132-144) with 3 pages of 4 buttons. The paging is controlled by
67 the summon flyout, which is also paged with the summon spells (the recall button is not paged)
68
69 - A spell list is updated in the secure context at setup time (TODO: redo setup when learning new
70 spells) with the list of spells known for each slot.
71
72 - Each button (except recall) has an arrow button which appears on mouseover and when clicked
73 opens the flyout via a wrapped OnClick handler. When the flyout is open, the arrow does not
74 appear.
75
76 - A single flyout with N+1 (1 slot is to select no totem for the set) flyout-buttons is a child
77 of the bar. Each time the flyout panel is opened, the individual buttons grab their corresponding
78 spell/type from the list, according to the slot which opened the flyout. Each button either sets
79 the current page (summon) or sets a multispell to an actionID via type="multispell". None of them
80 actually cast any spells (though, I suppose we could modify this so that e.g. configurable
81 right-click casts the spell). The flyout also has a close button which closes the flyout: the
82 flyout-open code positions the close button anchored to the last button in the flyout (which
83 changes dynamically because each slot has a different number of items in the list).
84
85 - Multicast sets are not stances, there's no need (or ability) to handle swapping sets if one of
86 the summon spells is cast from elsewhere.
87
88 - The default UI has Call of the Elements always selected on UI load. This module remembers the last
89 selected one and restores it.
