Arguments: grid-section-or-subsection
Returns the width in pixels that will be used to draw the border along
the right side of a grid-column
or grid-column-section
or along the
bottom side of a grid-row
or grid-row-section
. An application
may either call or override this generic function, though it typically
should not be necessary to do either, since border widths are usually
specified with the border-width and/or default-cell-border-width
properties, and effective-border-width is called
internally whenever a grid border line is drawn.
The default method for grid-subsection
(for a grid-row
or a grid-column
) will
return the border-width property of the
subsection if non-nil
. Otherwise it will
return the default-cell-border-width of the
grid-section
that contains the subsection, if non-nil
, or
else the default-cell-border-width property
of the whole grid-widget
, if non-nil
. If none of these properties have been
specified, then 1 is returned (since the return value must be an
actual width).
The default method for grid-section
(for a grid-row-section
or a
grid-column-section
) will return
the section's border-width property if non-nil
,
or else the default-cell-border-width property
of the whole grid-widget
, if non-nil
, or finally
2.
