System tray icon not showing (correctly) with Gnome (Xorg/Wayland)

[Jeansen]

Currently I am on Debian with Gnome 41.3.

When I run the https://github.com/JetBrains/compose-jb/tree/master/tutorials/Tray_Notifications_MenuBar_new I get two things:

• With Gnome on Wayland I get an icon, but the circle is double the size it should, be, therefore clipped and the background is white (instead of transparent)
• With Gnome on Xorg, I have a black icon.

Context menu works in both scenarios.

Note: Tray only works when this extension is installed: https://extensions.gnome.org/extension/615/appindicator-support/ .

On Windows, it works fine. On both systems I can invoke the tray menu, increase the counter and close the application. It's simply that the tray icon itself has issues with Gnome.

One addition: dorkbox.systemTray.SystemTray works perfectly fine with an older app I'd like to transition from JavaFX + Kotlin to Compose. That is, I have an tray icon with transparent background, the right icon size in Windows and Gnome (either Xorg or Wayland).

Fwiw: When using the Tray functionality, I get a JavaEmbeddedFrame task in my task switcher, which does display the requested tray icon.

Also when using multiple monitors, the resultant menu that opens when tapping on the tray icon, may appear on the incorrect display.

(On Gnome 40.4.0 and using X11 windowing system)

I tried again with OpenJDK 17, Compose 1.0.1 and Kotlin 1.6.10. Same issues. 1.2.0-alpha01-dev620 does not reveal any changes, either

I ended up using Dorkbox as @Jeansen recommended. Here's a little snippet on how to get up and running with it:

h3. Gradle dependency

implementation("com.dorkbox:SystemTray:4.1")

h3. Sample use

@Composable
fun DorkTray() {
    val tray by remember { mutableStateOf(SystemTray.get()!!) }

    LaunchedEffect(true) {
        tray.installShutdownHook() // Auto-remove icon when application is killed
        tray.setImage(javaClass.getResourceAsStream("/icon.png")) // Use icon in src/main/resources/icon.png
        tray.menu.add(MenuItem("Click me!").apply {
            setCallback { println("Handled click!") }
        })
    }
}

This should be enough to get someone going if they find themselves here.

Didn't you get this error @ChrisAJS loader 'bootstrap' attempted duplicate class definition for java.awt.TrayIcon. (java.awt.TrayIcon is in module java.desktop of loader 'bootstrap')

Did you solve this? Getting the same issue. : )

Just managed to run the cod of ChrisAJS by setting SystemTray.FORCE_TRAY_TYPE manually before the SystemTray.get() call to Swing on macOS (14.5):

fun DorkTray() {
    SystemTray.FORCE_TRAY_TYPE = SystemTray.TrayType.Swing
    val tray by remember { mutableStateOf(SystemTray.get()!!) }
