|
|
Examples
|
||
|
|
|
||
|
|
-- Position and size
|
||
|
|
local QuestIcon = self:CreateTexture(nil, 'OVERLAY')
|
||
|
|
QuestIcon:SetSize(16, 16)
|
||
|
|
QuestIcon:SetPoint('TOPRIGHT', self)
|
||
|
|
|
||
|
|
-- Register it with oUF

Hooks
|
||
|
|
|
||
|
|
Override(self) - Used to completely override the internal update function.
|
||
|

|
||
|
|
to its internal function again.
