--[[ Element: Raid Icon
|
|
|
|
Handles updating and toggles visibility of raid target icons.
|
|
|
|
Widget
|
|
|
|
RaidIcon - A Texture used to display the raid target icon.
|
|
|
|
Notes
|
|
|
|
This element updates by changing the texture.
|
|
|
|
The default raid icons will be used if the UI widget is a texture and doesn't
|
|
have a texture or color defined.
|
|
|
|
Examples
|
|
|
|
-- Position and size
|
|
local RaidIcon = self:CreateTexture(nil, 'OVERLAY')
|
|
RaidIcon:SetSize(16, 16)
|
|
RaidIcon:SetPoint('TOPRIGHT', self)
|
|
|
|
-- Register it with oUF
|
|
self.RaidIcon = RaidIcon
|
|
|
|
Hooks
|
|
|
|
Override(self) - Used to completely override the internal update function.
|
|
Removing the table key entry will make the element fall-back
|
|
to its internal function again.
