Struct Tray

pub struct Tray { /* private fields */ }

Interface for creating system tray icons and menus. For usage example please refer to nw_sys::tray

Tray is an abstraction of different controls on different platforms, usually it’s a small icon shown on the OS’s notification area. On Mac OS X it’s called Status Item, on GTK it’s Status Icon, and on Windows it’s System Tray Icon.

Implementations

impl Tray

pub fn new(options: &Options) -> Tray

Synopsis

//Create a tray icon
let tray = nw_sys::Tray::new(&nw_sys::tray::Options::new().title("Tray").icon("img/icon.png"));

Create a new Tray, option is an contains initial settings for the Tray. Every field has its own property in the Tray, see documentation of each property for details.

impl Tray

pub fn title(&self) -> String

Get the title of the tray.

⧉ NWJS Documentation

impl Tray

pub fn set_title(&self, title: &str)

Set the title of the tray.

⧉ NWJS Documentation

impl Tray

pub fn tooltip(&self) -> String

Get the tooltip of the tray.

⧉ NWJS Documentation

impl Tray

pub fn set_tooltip(&self, tooltip: &str)

Set the tooltip of the tray. tooltip shows when you hover the Tray with mouse. On Mac OS X title will be showed on status bar along with its icon, but it doesn’t have effects on GTK and Windows, since the latter two platforms only support tray to be showed as icons.

Note:

tooltip is showed on all three platforms. Should be set as Tray property rather from option object constructor.

impl Tray

pub fn icon(&self) -> String

Get the icon of the tray.

impl Tray

pub fn set_icon(&self, icon: &str)

Set the icon of the tray. Icon must a path to your icon file. It can be a relative path which points to an icon in your app, or an absolute path pointing to a file in user’s system.

Mac OS X caveat: when used in notification context, png icon is not sized down like in windows notification area, it is rather displayed in 1:1 ratio.

impl Tray

pub fn alticon(&self) -> String

(Mac) Get the alternate (active) tray icon.

impl Tray

pub fn set_alticon(&self, alticon: &str)

(Mac) Set the alternate (active) tray icon.

⧉ NWJS Documentation

impl Tray

pub fn icons_are_templates(&self) -> bool

(Mac) Get whether icon and alticon images are treated as “templates” (true by default). When the property is set to true the images are treated as “templates” and the system automatically ensures proper styling according to the various states of the status item (e.g. dark menu, light menu, etc.). Template images should consist only of black and clear colours and can use the alpha channel in the image to adjust the opacity of black content.

pub fn set_icons_are_templates(&self, value: bool)

(Mac) Set whether icon and alticon images are treated as “templates” (true by default).

pub fn menu(&self) -> Option<Menu>

Get the menu of the tray

impl Tray

pub fn set_menu(&self, menu: &Menu)

Set the menu of the tray, menu will be showed when you click on the tray icon.

let menu = nw_sys::Menu::new();
menu.append(&nw_sys::MenuItem::new(&nw_sys::menu_item::Options::new().label("Menu 1")));
tray.set_menu(&menu);

⧉ NWJS Documentation

impl Tray

pub fn remove(&self)

Remove the tray

tray = null;<–– TODO

Once removed, you will not be able to show it again and you should set your tray variable to null to make it garbage collected. There is no way temporarily hide a tray icon.

impl Tray

pub fn on(&self, event: &str, callback: &Function)

Event handling: Click

Emitted when user clicks the menu item with left mouse button.

Methods from Deref<Target = JsValue>

pub const NULL: JsValue

pub const UNDEFINED: JsValue

pub const TRUE: JsValue

pub const FALSE: JsValue

pub fn as_f64(&self) -> Option<f64>

Returns the f64 value of this JS value if it’s an instance of a number.

If this JS value is not an instance of a number then this returns None.

pub fn is_string(&self) -> bool

Tests whether this JS value is a JS string.

pub fn as_string(&self) -> Option<String>

If this JS value is a string value, this function copies the JS string value into Wasm linear memory, encoded as UTF-8, and returns it as a Rust String.

To avoid the copying and re-encoding, consider the JsString::try_from() function from js-sys instead.

If this JS value is not an instance of a string or if it’s not valid utf-8 then this returns None.

UTF-16 vs UTF-8

JavaScript strings in general are encoded as UTF-16, but Rust strings are encoded as UTF-8. This can cause the Rust string to look a bit different than the JS string sometimes. For more details see the documentation about the str type which contains a few caveats about the encodings.

pub fn as_bool(&self) -> Option<bool>

Returns the bool value of this JS value if it’s an instance of a boolean.

If this JS value is not an instance of a boolean then this returns None.

pub fn is_null(&self) -> bool

Tests whether this JS value is null

pub fn is_undefined(&self) -> bool

Tests whether this JS value is undefined

pub fn is_symbol(&self) -> bool

Tests whether the type of this JS value is symbol

pub fn is_object(&self) -> bool

Tests whether typeof self == "object" && self !== null.

pub fn is_array(&self) -> bool

Tests whether this JS value is an instance of Array.

pub fn is_function(&self) -> bool

Tests whether the type of this JS value is function.

pub fn is_bigint(&self) -> bool

Tests whether the type of this JS value is bigint.

pub fn js_typeof(&self) -> JsValue

Applies the unary typeof JS operator on a JsValue.

MDN documentation

pub fn js_in(&self, obj: &JsValue) -> bool

Applies the binary in JS operator on the two JsValues.

MDN documentation

pub fn is_truthy(&self) -> bool
