NAME
notcurses_reel - high-level widget for hierarchical data
SYNOPSIS
#include <notcurses.h>
typedef struct ncreel_options {
// require this many rows and columns (including borders).
// otherwise, a message will be displayed stating that a
// larger terminal is necessary, and input will be queued.
// if 0, no minimum will be enforced. may not be negative.
// note that ncreel_create() does not return error if
// given a WINDOW smaller than these minima; it instead
// patiently waits for the screen to get bigger.
int min_supported_cols;
int min_supported_rows;
// use no more than this many rows and columns (including
// borders). may not be less than the corresponding minimum.
// 0 means no maximum.
int max_supported_cols;
int max_supported_rows;
// desired offsets within the surrounding WINDOW (top right
// bottom left) upon creation / resize. an ncreel_move()
// operation updates these.
int toff, roff, boff, loff;
// is scrolling infinite (can one move down or up forever, or is
// an end reached?). if true, 'circular' specifies how to handle
// the special case of an incompletely-filled reel.
bool infinitescroll;
// is navigation circular (does moving down from the last panel
// move to the first, and vice versa)? only meaningful when
// infinitescroll is true. if infinitescroll is false, this must
// be false.
bool circular;
// notcurses can draw a border around the ncreel, and also
// around the component tablets. inhibit borders by setting all
// valid bits in the masks. partially inhibit borders by setting
// individual bits in the masks. the appropriate attr and pair
// values will be used to style the borders. focused and
// non-focused tablets can have different styles. you can instead
// draw your own borders, or forgo borders entirely.

unsigned tabletmask; // bitfield for tablet borders
