README
tray-icon lets you create tray icons for desktop applications.
## Platforms supported:
- Windows
- macOS
- Linux (gtk Only)
## Platform-specific notes:
- On Windows and Linux, an event loop must be running on the thread, on Windows, a win32 event loop and on Linux, a gtk event loop. It doesn't need to be the main thread but you have to create the tray icon on the same thread as the event loop.
- On macOS, an event loop must be running on the main thread so you also need to create the tray icon on the main thread.
### Cargo Features
- `common-controls-v6`: Use `TaskDialogIndirect` API from `ComCtl32.dll` v6 on Windows for showing the predefined `About` menu item dialog.
- `libxdo`: Enables linking to `libxdo` which is used for the predfined `Copy`, `Cut`, `Paste` and `SelectAll` menu item, see https://github.com/tauri-apps/muda#cargo-features
- `serde`: Enables de/serializing derives.
## Dependencies (Linux Only)
On Linux, `gtk`, `libxdo` is used to make the predfined `Copy`, `Cut`, `Paste` and `SelectAll` menu items work and `libappindicator` or `libayatnat-appindicator` are used to create the tray icon, so make sure to install them on your system.
#### Arch Linux / Manjaro:
```sh
pacman -S gtk3 xdotool libappindicator-gtk3 #or libayatana-appindicator
```
#### Debian / Ubuntu:
```sh
sudo apt install libgtk-3-dev libxdo-dev libappindicator3-dev #or libayatana-appindicator3-dev
```
## Examples
#### Create a tray icon without a menu.
```rs
use tray_icon::TrayIconBuilder;
let tray_icon = TrayIconBuilder::new()
.with_tooltip("system-tray - tray icon library!")
.with_icon(icon)
.build()
.unwrap();
```
#### Create a tray icon with a menu.
```rs
use tray_icon::{TrayIconBuilder, menu::Menu};
let tray_menu = Menu::new();
let tray_icon = TrayIconBuilder::new()
.with_menu(Box::new(tray_menu))
.with_tooltip("system-tray - tray icon library!")
.with_icon(icon)
.build()
.unwrap();
```
## Processing tray events
You can use `TrayIconEvent::receiver` to get a reference to the `TrayIconEventReceiver`
which you can use to listen to events when a click happens on the tray icon
```rs
use tray_icon::TrayIconEvent;
if let Ok(event) = TrayIconEvent::receiver().try_recv() {
println!("{:?}", event);
}
```
You can also listen for the menu events using `MenuEvent::receiver` to get events for the tray context menu.
```rs
use tray_icon::{TrayIconEvent, menu::{MenuEvent}};
if let Ok(event) = TrayIconEvent::receiver().try_recv() {
println!("tray event: {:?}", event);
}
if let Ok(event) = MenuEvent::receiver().try_recv() {
println!("menu event: {:?}", event);
}
```
### Note for [winit] or [tao] users:
You should use [`TrayIconEvent::set_event_handler`] and forward
the tray icon events to the event loop by using [`EventLoopProxy`]
so that the event loop is awakened on each tray icon event.
Same can be done for menu events using [`MenuEvent::set_event_handler`].
```rust
enum UserEvent {
TrayIconEvent(tray_icon::TrayIconEvent)
MenuEvent(tray_icon::menu::MenuEvent)
}
let event_loop = EventLoop::::with_user_event().build().unwrap();
let proxy = event_loop.create_proxy();
tray_icon::TrayIconEvent::set_event_handler(Some(move |event| {
proxy.send_event(UserEvent::TrayIconEvent(event));
}));
let proxy = event_loop.create_proxy();
tray_icon::menu::MenuEvent::set_event_handler(Some(move |event| {
proxy.send_event(UserEvent::MenuEvent(event));
}));
```
