# Element: Runes
|
||||
|
||||
Handles the visibility and updating of Death Knight's runes.
|
||||
|
||||
## Widget
|
||||
|
||||
Runes - An `table` holding `StatusBar`s.
|
||||
|
||||
## Sub-Widgets
|
||||
|
||||
.bg - A `Texture` used as a background. It will inherit the color of the main StatusBar.
|
||||
|
||||
## Notes
|
||||
|
||||
A default texture will be applied if the sub-widgets are StatusBars and don't have a texture set.
|
||||
|
||||
## Options
|
||||
|
||||
.colorSpec - Use `self.colors.runes[specID]` to color the bar based on player's spec. `specID` is defined by the return
|
||||
value of [GetSpecialization](http://wowprogramming.com/docs/api/GetSpecialization.html) (boolean)
|
||||
.sortOrder - Sorting order. Sorts by the remaining cooldown time, 'asc' - from the least cooldown time remaining (fully
|
||||
charged) to the most (fully depleted), 'desc' - the opposite (string?)['asc', 'desc']
|
||||
|
||||
## Sub-Widgets Options
|
||||
|
||||
.multiplier - Used to tint the background based on the main widgets R, G and B values. Defaults to 1 (number)[0-1]
|
||||
|
||||
