|
|
Widget
|
||
|
|
|
||
|
|
LFDRole - A Texture containing the LFD role icons at specific locations. Look
|
||
|
|
at the default LFD role icon texture for an example of this.
|
||
|
|
Alternatively you can look at the return values of
|
||
|
|
GetTexCoordsForRoleSmallCircle(role).
|
||
|
|
|
||
|
|
Notes
|
||
|
|
|
||
|
|
The default LFD role texture will be applied if the UI widget is a texture and
|
||
|
|
doesn't have a texture or color defined.
|
||
|
|
|
||
|
|
Examples
|
||
|
|
|
||
|
|
-- Position and size
|
||
|
|
local LFDRole = self:CreateTexture(nil, "OVERLAY")

|
|
LFDRole:SetPoint("LEFT", self)

|
-- Register it with oUF

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.
