# NAME

notcurses_reel - high-level widget for hierarchical data

# SYNOPSIS

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

```c
#define NCREEL_OPTION_INFINITESCROLL 0x0001
#define NCREEL_OPTION_CIRCULAR       0x0002

typedef struct ncreel_options {
  // 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 bordermask; // bitfield; 1s will not be drawn
  uint64_t borderchan; // attributes used for ncreel border
  unsigned tabletmask; // bitfield for tablet borders
  uint64_t tabletchan; // tablet border styling channel
  uint64_t focusedchan;// focused tablet border styling channel
  uint64_t bgchannel;  // background colors
  unsigned flags;      // bitfield over NCREEL_OPTION_*
} ncreel_options;
