Struct TitlebarOptions 

pub struct TitlebarOptions {
    pub title: Option<SharedString>,
    pub appears_transparent: bool,
    pub traffic_light_position: Option<Point<Pixels>>,
}

Options for a window’s titlebar.

Chain setters on TitlebarOptions::default and pass the result to WindowOptions::titlebar. Pass None to clear the title or traffic light position.

use gpui::{SharedString, TitlebarOptions, point, px};

let titlebar = TitlebarOptions::default()
    .title(SharedString::from("My app"))
    .appears_transparent(true)
    .traffic_light_position(point(px(16.0), px(16.0)));

assert_eq!(titlebar.title, Some(SharedString::from("My app")));
assert!(titlebar.appears_transparent);

Fields

title: Option<SharedString>

The window’s initial title. The web backend ignores it.

appears_transparent: bool

Whether to hide the system titlebar so you can draw your own. macOS and Windows only. On Linux, use WindowOptions::window_decorations instead.

traffic_light_position: Option<Point<Pixels>>

The position of the macOS traffic-light buttons, in logical pixels. macOS only.

Implementations

impl TitlebarOptions

pub fn title(self, value: impl Into<Option<SharedString>>) -> Self

Sets the title field of this struct.

pub fn appears_transparent(self, value: impl Into<bool>) -> Self

Sets the appears_transparent field of this struct.

pub fn traffic_light_position( self, value: impl Into<Option<Point<Pixels>>>, ) -> Self

Sets the traffic_light_position field of this struct.

Trait Implementations

impl Debug for TitlebarOptions

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

Formats the value using the given formatter.

impl Default for TitlebarOptions

fn default() -> Self

Returns the “default value” for a type.

impl FluentBuilder for TitlebarOptions

fn map<U>(self, f: impl FnOnce(Self) -> U) -> U

where Self: Sized,

Passes self to f, and returns the result. Use it to continue a chain with a closure.

fn when(self, condition: bool, then: impl FnOnce(Self) -> Self) -> Self

where Self: Sized,

Calls then with self if condition is true. Otherwise returns self unchanged.

fn when_else( self, condition: bool, then: impl FnOnce(Self) -> Self, else_fn: impl FnOnce(Self) -> Self, ) -> Self

where Self: Sized,

Calls then with self if condition is true, and else_fn with self otherwise.

fn when_some<T>( self, option: Option<T>, then: impl FnOnce(Self, T) -> Self, ) -> Self

where Self: Sized,

Calls then with self and the value inside option if the option is Some. Returns self unchanged for None.

fn when_none<T>( self, option: &Option<T>, then: impl FnOnce(Self) -> Self, ) -> Self

where Self: Sized,

Calls then with self if option is None. The option is taken by reference, so you can still use it afterward.
