TICKIT_RECT(7) Miscellaneous Information Manual TICKIT_RECT(7)

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).
