Arguments: object
Returns the default background color for
object. This color will be used as the background
color when the value of the background-color property is
nil.
The built-in methods are specialized on the window class. Thus, for
example, the default for dialog is returned by system-dialog-background-color and
for basic-pane
is returned by system-background-color.
Contrast with the built-in method for default-foreground-color, which is the value returned by system-foreground-color whatever the type of window.
Note: incompatible change in release 6.0: in releases prior
to 6.0, when a frame-with-single-child instance
was passed to this operator, the operator was actually applied to the
child (the result of applying frame-child to the
frame-with-single-child instance). In release 6.0, this redirection no
longer occurs. If you intend this operator to apply to the
frame-child, pass that to this operator rather than the parent. This
is a non-backward-compatible-change. See the release notes for more
information.
