我正在尝试使用 compose 创建一个多窗口桌面应用程序。

他们将拥有完全不同的屏幕。一个是主屏幕，另一个是子屏幕。我试过这样。

子屏幕旨在由共享演示器内的某些状态流显示，它将在主屏幕上调用为 true，但为了使代码简短，我已经删除了该部分。

fun main() = application {


val windowState = rememberWindowState()
val subWindowState = rememberWindowState()

var isVisible by remember { mutableStateOf(true) }


var isSubScreenVisible by remember { mutableStateOf(false) }


val onVisibilityChanged : (Boolean) -> Unit = {
    isVisible = it
}

setTray(this) {
    isVisible = it
}

//Sub screen
Window(onCloseRequest = {
        isSubScreenVisible = false
    },
    title = "SubScreen",
    state = subWindowState,
    undecorated = true,
    resizable = false,
    visible = isSubScreenVisible,
    transparent = true) {
 
} {
  AppTheme(darkTheme = false) {
    //my sub screen composable..
  }
}

//Main Screen
Window(
    onCloseRequest = {
        onVisibilityChanged(false)
    },
    icon = painterResource("logo.png"),
    title = "Main Screen",
    state = windowState,
    undecorated = true,
    resizable = false,
    visible = isVisible,
    transparent = true
){
    AppTheme(darkTheme = false) {

        val rootState by mPresenter.mRootState.collectAsState()
        when(rootState){
            is RootState.Splash -> {
                showMessage("[RootNav] Splash")
                Splash(this, mPresenter)
            }
            is RootState.NotLoggedIn -> {
                showMessage("[RootNav] Login")
                Login(mPresenter, this, windowState, onVisibilityChanged)
            }
            is RootState.LoggedIn -> {
                showMessage("[RootNav] Main")
                MainFrame(this, windowState, onVisibilityChanged)
            }
        }
    }
}

}

此代码导致此异常。

Exception in thread "main" java.awt.IllegalComponentStateException: The frame is displayable.

此错误发生在主屏幕窗口上，并且没有显示任何内容。

这是什么意思？是否允许多个窗口，因为有 SingleWindowApplication 之类的东西？

我能做些什么 ？
