effective-border-width

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.
