cell-3d-border

Arguments: row column

This generic function returns whether the grid cell at the intersection of the specified grid-row and grid-column will be drawn with a pseudo-three-dimensional border. Applications may add cell-3d-border methods to determine which cells (if any) will have a 3d border. This border, if drawn, is in addition to the "regular" border (see border-width and default-cell-border-width).

If the returned value is nil (the default), then no 3d borders will be drawn. If it is the keyword :sunken-edge, then 3d borders will be drawn that appear sunken (making the grid cells appear raised). If it is t, then 3d borders will be drawn that appear raised (making the grid cells appear sunken).

The default method returns the value of the default-cell-3d-border property of the grid-row-section, the grid-column-section, or the grid-widget (in that order) that contains the specified cell, if any of those property values is non-nil, and otherwise it returns nil. (The default value of the default-cell-3d-border property is nil, so nil is returned from this default method if the property has not been specified for any of those objects.)
