--[[ Element: Combat Icon
|
|
Toggles the visibility of `self.Combat` based on the player's combat status.
|
|
|
|
Widget
|
|
|
|
Combat - Any UI widget.
|
|
|
|
Notes
|
|
|
|

|
|
doesn't have a texture or color defined.
|
|
|
|
Examples
|
|
|
|
-- Position and size
|
|
local Combat = self:CreateTexture(nil, "OVERLAY")
|
|
Combat:SetSize(16, 16)
|
|
Combat:SetPoint('TOP', self)
|
|
|
|
-- Register it with oUF
|
|
self.Combat = Combat
|
|
|
|
Hooks
|
|
|
|
Override(self) - Used to completely override the internal update function.
|
|

|
|
to its internal function again.
