## border-width

Arguments: grid-object

Returns the width in pixels, if one has been specified, with which to draw a border along the right side of a `grid-column` or `grid-column-section`, or along the bottom of a `grid-row` or `grid-row-section`, or around an entire `grid-widget`. The setf of this function may be called to change the width, at which time the grid will be drawn as needed to display the new border width.

The value may be either a non-negative integer or `nil`. The initial value is `nil`. When `nil`, effective-border-width will find a width to use in some other way. Zero means to draw no border at all (though cell-3d-border may still be used to draw a separate 3d border).

An exception to the above rule is that if the object is a `grid-widget` then `nil` is not a valid value, the initial value is 3, and effective-border-width is not called.
