Arguments: grid-widget section &optional include-border-p box
Returns a box or nil
indicating where a grid
section lies on the grid widget window, clipped according to grid
boundaries and section boundaries.
When the specified section or subsection is scrolled completely out of
view, this function returns nil
. Otherwise it
returns a box that reflects the visible part of the specified grid
section.
grid-widget is the grid-widget
containing
the section.
section is the section whose box is being
returned. This should be either a grid-row-section
, grid-column-section
, grid-row
, or grid-column
.
If include-border-p is true, then the area occupied by the border line at the right or bottom edge of the section is included in the returned box. Otherwise it is excluded.
box may be either a box (see make-box) or nil
. If a box, then that box is modified and
returned. If nil
, a new box object is
created and returned. Passing a scratch box avoids consing one that
must be garbage collected.
