cross-section-box

Arguments: grid-widget row-or-row-section column-or-column-section &optional include-border-p box

Returns a box for the intersection of a grid-row or grid-row-section with a grid-column or grid-column-section. The box excludes any parts of the sections or subsections that are currently scrolled out of view.

When the specified cross-section is scrolled completely out of view, this function returns nil.

grid-widget is the grid-widget itself.

row-or-row-section is either a grid-row or a grid-row-section.

column-or-column-section is either a grid-column or a grid-column-section.

If include-border-p is true, then the area occupied by the border lines at the right and bottom edges of the cross-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.
