I want to know, is there a way to set the background color of the system decoration without setting undecorated to true?

fun main() = application {
    Window(
        onCloseRequest = ::exitApplication, title = "Test", icon = painterResource(Res.drawable.icon)
    ) {
        App()
    }
}

You can set light/dark/system theme on macOS. Beyond that, I don’t think you can.

I set the appearance to dark in macOS settings, but the system decoration did not change the color

Pass -Dapple.awt.application.appearance=system
to the JVM, or set it as a System property.

[LazyIonEs]

compose.desktop {
    application {
        jvmArgs += listOf("-Dapple.awt.application.appearance=system")
    }
}

Is this the setting? I didn't get the corresponding effect.

[Alexander Maryanovsky]

Are you running the app via the gradle run task?

[LazyIonEs]

I ran the main function directly, and it worked after I tried using the run task. Thank you. I would like to ask if it is also applicable to Windows?

[Alexander Maryanovsky]

It’s not

[LazyIonEs]

OK, I understand

@LazyIonEs It's possible thanks to my library under Windows too
