Struct FocusGroup 

pub struct FocusGroup {
    pub id: String,
    pub fields: Vec<FormField>,
    pub wrap: bool,
}

A declarative form / focus group (FORM-1): fields in order, each with an optional hint key + rect (filled at layout). Single tab-stop to enter; directional arrows move between fields; the hint overlay extends to fields (FORM-2). Code-defined, deterministic.

Fields

id: String

fields: Vec<FormField>

wrap: bool

Implementations

impl FocusGroup

pub fn new(id: impl Into<String>) -> Self

pub fn field( self, id: impl Into<String>, hint: Option<char>, rect: Rect, ) -> Self

pub fn wrap(self, wrap: bool) -> Self

pub fn hint_target(&self, key: char) -> Option<usize>

Index of the field with hint key key (FORM-2 hint jump).

pub fn move_dir(&self, current: usize, dir: Dir4) -> Option<usize>

The field a directional move from current lands on (FORM-2), using the shared spatial rule. Wraps to first/last when wrap and nothing lies that way. Returns the new field index.

Performs copy-assignment from source.

impl Debug for FocusGroup

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for FocusGroup

fn default() -> FocusGroup
