Struct FormView 

pub struct FormView<'a, F> {
    pub title: &'a str,
    pub screen: Context,
    pub footer: Option<HintBar>,
    pub label_width: u16,
    pub rows: Vec<FormLine<'a, F>>,
    pub focused: Option<F>,
    pub picker: Option<&'a PickerState>,
    pub status: Option<(String, Style)>,
    pub shields: bool,
}

What a form dialog draws. footer is the form’s own keys; while a picker is open its keys stand in, from the Picker group of screen’s registry entries.

Fields

title: &'a str

screen: Context

footer: Option<HintBar>

label_width: u16

Where the values start, past the longest label.

rows: Vec<FormLine<'a, F>>

The fields shown, in order, with the lines they bring.

focused: Option<F>

The field with the rail; None while something beside the form has the focus.

picker: Option<&'a PickerState>

status: Option<(String, Style)>

The last line: what Enter will do, or what stops it. While it is Some, a blank and the line are kept under the rows, empty or not, so nothing moves when a reason comes. A long one wraps upward into rows the fields leave free.

shields: bool

Whether its whole area takes no clicks but its own, as a dialog over the screen. false only where the caller decides what is around it: the Sample form inline beside the analysis tools, or over a pane the caller shields.

Implementations

impl<'a, F: Copy + PartialEq> FormView<'a, F>

pub fn render<T: Form<Field = F>>( self, area: Rect, buf: &mut Buffer, ctx: &RenderContext, )

Draw it in area, recording each field’s row for clicks.

pub fn render_unrecorded( self, area: Rect, buf: &mut Buffer, ctx: &RenderContext, )

Draw it in area for a form whose fields take no clicks.
