Struct CommandLine 

pub struct CommandLine {
    pub id: WidgetId,
    pub text: String,
    pub cursor_offset: Option<usize>,
    pub right_align: bool,
}

Declarative description of a command line surface.

Examples

use quadraui::{CommandLine, CommandLineMeasure, Rect, WidgetId};

let cmd = CommandLine {
    id: WidgetId::new("cmdline:editor"),
    text: ":wq".to_string(),
    cursor_offset: Some(3),
    right_align: false,
};

let rect = Rect::new(0.0, 23.0, 80.0, 1.0);
let layout = cmd.layout(rect, CommandLineMeasure::new(1.0));

assert_eq!(layout.hit_test(0.0), 0);
assert_eq!(layout.hit_test(100.0), cmd.text.len());

Fields

id: WidgetId

text: String

Full display text (includes prompt character if any, e.g. :wq).

cursor_offset: Option<usize>

Byte offset within text at which to draw the insert cursor. None suppresses the cursor (message-display mode).

right_align: bool

When true, right-align the text (used for count/match displays).

Implementations

impl CommandLine

pub fn layout( &self, rect: Rect, measure: CommandLineMeasure, ) -> CommandLineLayout
