# Element: ComboPoints
|
|
|
|
Handles the visibility and updating of the player's combo points.
|
|
|
|
## Widget
|
|
|
|
ComboPoints - An `table` consisting of as many Textures as the theoretical maximum return of [GetComboPoints](http://wowprogramming.com/docs/api/GetComboPoints).
|
|
|
|
## Notes
|
|
|
|
A default texture will be applied if the widget is a Texture and doesn't have a texture or a color set.
|
|
|
|
## Examples
|
|
|
|
local ComboPoints = {}
|
|
for index = 1, 10 do
|
|
local Bar = CreateFrame('StatusBar', nil, self)
|
|
|
|
-- Position and size.
|
|
Bar:SetSize(16, 16)
|
|
Bar:SetPoint('TOPLEFT', self, 'BOTTOMLEFT', (index - 1) * Bar:GetWidth(), 0)
|
|
|
|
ComboPoints[index] = Bar
