# NAME

notcurses_selector - high level widget for selecting from a set

# SYNOPSIS

**#include <notcurses/notcurses.h>**

```c
struct ncinput;
struct ncplane;
struct notcurses;
struct ncselector;

struct ncselector_item {
  char* option;
  char* desc;
};

typedef struct ncselector_options {
  char* title; // title may be NULL, inhibiting riser
  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
  unsigned flags;        // bitfield over NCSELECTOR_OPTION_*
} ncselector_options;
```

**struct ncselector* ncselector_create(struct ncplane* n, int y, int x, const ncselector_options* opts);**

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

**int ncselector_delitem(struct ncselector* n, const char* item);**

**const char* ncselector_selected(const struct ncselector* n);**

**struct ncplane* ncselector_plane(struct ncselector* n);**

**const char* ncselector_previtem(struct ncselector* n);**

**const char* ncselector_nextitem(struct ncselector* n);**

**bool ncselector_offer_input(struct ncselector* n, const struct ncinput* nc);**

**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**.
