[bug] set_menu is not working under Linux for tauri 2.0.0

[vangork]

Describe the bug

On linux when upgrade to tauri 2.0, using TrayIconBuilder the menu is not shown upon click (left or right)

Reproduction

tauri.conf.json:

"trayIcon": {
      "iconAsTemplate": false,
      "iconPath": "icons/icon.png"
},

main.rs

let config = MenuItemBuilder::with_id("config", "config").build(app_handle);
let exit = MenuItemBuilder::with_id("exit", "exit").build(app_handle);
let seperator = PredefinedMenuItem::separator(app_handle);
let tray_menu = MenuBuilder::new(app_handle).items(&[&config, &seperator, &exit]).build().unwrap();
let tray = app_handle.tray().unwrap();
tray.set_menu(Some(tray_menu)).unwrap();

In additional, since tauri 2.0.0 removed get_item() method in the app_handle.tray(), how should I change the title for an existing menuitem?

Expected behavior

The menu should show up upon click of the tray icon.

Thanks for the report, I believe this is the same as https://github.com/tauri-apps/tray-icon/issues/89 and will hopefully will be fixed in the next release.

@amrbashir Thanks for the response. BTW, since tauri 2.0.0 removed get_item() method in the app_handle.tray(), how should I change the title for an existing menu item?

@amrbashir Meanwhile, on_tray_icon_event is not working neither on Linux.

I believe you want to see the menu events of the tray, in this case, use .on_menu_event
