| Allegro CL version 6.2 Unrevised from 6.1 |
Arguments: object
Returns the color returned by background-color for
object if that function returns a color (rather than t or nil
).
The value will be an RGB color (as returned by make-rgb). See hls-to-rgb and rgb-to-hls.
If background-color returns nil
, effective-background-color returns
the color returned by default-background-color for
object. (As of 5.0, background-color returns nil
when no background color has been explicitly
assigned to an object.)
If background-color returns t for a control, indicating that the control's background color should be the same as its parent window's background color, then the effective-background-color of the parent window is returned.
