NAME

       TickitRect - utility structure representing a rectangular region

SYNOPSIS

       #include <tickit.h>

       typedef struct {
         int top;
         int left;
         int lines;
         int cols;
       } TickitRect;

DESCRIPTION

       A  TickitRect structure represents a single non-empty rectangular region of the screen. It
       stores the position of the top left corner of the  region,  and  its  size  in  lines  and
       columns.

FUNCTIONS

       A  new  TickitRect  structure  can  be initialised using the tickit_rect_init_sized(3) and
       tickit_rect_init_bounded(3) functions. Its bottom  right  corner  can  be  obtained  using
       tickit_rect_bottom(3)  and  tickit_rect_right(3).  Interactions  between rectangles can be
       tested     using     the     predicate     functions      tickit_rect_contains(3)      and
       tickit_rect_intersects(3).  New  rectangles  can  be  created  from  existing  ones  using
       tickit_rect_intersect(3) to form the intersection, tickit_rect_add(3) to  form  the  union
       sum, and tickit_rect_subtract(3).
