kotlin.NotImplementedError: An operation is not implemented: not implemented AlertDialog

Question

我正在尝试使用 kotlin 的桌面组合进行一些练习，当我尝试实现 AlertDialog 元素时，我遇到了这个异常：

Exception in thread "AWT-EventQueue-0 @coroutine#3" kotlin.NotImplementedError: An operation is not implemented: not implemented

我正在尝试的代码运行 :

fun main() {
    var text = mutableStateOf(0F)
    var num = mutableStateOf("a")
    Window(
        size = IntSize(500, 500),
        title = num.value,
        menuBar = MenuBar(
            Menu(
                name = "Test",
                MenuItem(
                    name = "Dodaj random",
                    onClick = {
                        text.value = text.value + Random.nextFloat()
                        if (text.value > 1F) {
                            text.value = 0F
                            num.value += "a"
                        }
                    },
                    shortcut = KeyStroke(Key.A)
                ),
                MenuItem(
                    name = "Exit",
                    onClick = {
                        AppManager.exit()
                    },
                    shortcut = KeyStroke(Key.L)
                )
            )
        )
    ) {

        MaterialTheme {
            Column(Modifier.fillMaxSize(), Arrangement.spacedBy(12.dp)) {
                LinearProgressIndicator(text.value.toFloat(), modifier = Modifier.align(Alignment.CenterHorizontally))
                val openDialog = remember { mutableStateOf(false) }
                Button(
                    onClick = {
                        openDialog.value = true
                    }) {
                    Text("Click me!")
                }
                if (openDialog.value) {
                    AlertDialog(
                        onDismissRequest = { openDialog.value = false },
                        title = { Text("Dialog title") },
                        text = { Text("Here is a text") },
                        confirmButton = {
                            Button(
                                onClick = {
                                    openDialog.value = false
                                }
                            ) { Text("Confirm butt") }
                        },
                        dismissButton = {
                            Button(
                                onClick = {
                                    openDialog.value = false
                                }
                            ) { Text("Diss butt") }
                        }
                    )
                }
                Button(
                    onClick = {
                        text.value += 0.1F
                        if (text.value > 1F) {
                            text.value = 0F
                            num.value += "a"
                        }
                    },
                    modifier = Modifier.align(Alignment.CenterHorizontally)
                ) {
                    Text(text.value.toString())
                }

                Button(
                    onClick = {
                        num.value += "a"
                    },
                    modifier = Modifier.align(Alignment.CenterHorizontally)
                ) {
                    Text(num.component1())
                }


            }
        }
    }
}

仅当我尝试单击“单击我”按钮时出现此异常，其他按钮工作正常。

您的问题似乎与 this github 问题有关。

要解决它，只需将 compose 依赖项更新为 0.2.0-build132。

我的 build.gradle 的完整示例以及正确的版本：

import org.jetbrains.compose.compose

plugins {
    kotlin("jvm") version "1.4.20"
    id("org.jetbrains.compose") version "0.2.0-build132"
}

repositories {
    jcenter()
    maven("https://maven.pkg.jetbrains.space/public/p/compose/dev")
}

dependencies {
    implementation(compose.desktop.currentOs)
}

compose.desktop {
    application {
        mainClass = "MainKt"
    }
}
