SYNOPSIS

struct ncplane;
struct notcurses;
struct ncselector;
struct ncselector_item {
char* option;
char* desc;
};

char* secondary; // secondary may be NULL
char* footer; // footer may be NULL
struct ncselector_item* items; // initial items and descriptions
unsigned itemcount; // number of initial items and descriptions
// default item (selected at start)
unsigned defidx;
// maximum number of options to display at once
unsigned maxdisplay;
// exhaustive styling options
uint64_t opchannels; // option channels
uint64_t descchannels; // description channels
uint64_t titlechannels;// title channels
uint64_t footchannels; // secondary and footer channels
uint64_t boxchannels; // border channels
uint64_t bgchannels; // background channels for body

int ncselector_additem(struct ncselector n, const struct ncselector_item item);**

const char ncselector_selected(const struct ncselector n);**
struct ncplane ncselector_plane(struct ncselector n);**
const char ncselector_previtem(struct ncselector n);**

void ncselector_destroy(struct ncselector n, char** item);*
DESCRIPTION
NOTES
Currently, the ncplane n provided to ncselector_create must not be NULL, though the ncselector will always get its own plane, and this plane will not (currently) be bound to n.
