# SYNOPSIS
|
|
|
|
**#include <notcurses.h>**
|
|
|
|
```c
|
|
typedef struct panelreel_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 panelreel_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. a panelreel_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 panelreel, 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.
|
