I’m seeing errors when notarizing an application with files from compose. How would I work around that?

Hi I’m having an issue with expect/actual composable function when built from scratch app works without exception but when make any change to my app and rerun sometimes throwing error

java.lang.NoSuchMethodError: No static method Blablabla

Upgrading to 

v1.0.0-alpha1-rc1

 throws the following error :

Could not find androidx.annotation:annotation:1.2.0.

Required by:
            project : > org.jetbrains.compose.ui:ui-tooling:1.0.0-alpha1-rc1 > org.jetbrains.compose.ui:ui-tooling-desktop:1.0.0-alpha1-rc1 > org.jetbrains.compose.ui:ui-tooling-preview:1.0.0-alpha1-rc1 > org.jetbrains.compose.ui:ui-tooling-preview-desktop:1.0.0-alpha1-rc1

Am I missing something?

i cloned

JetBrains/compose-jb

and did

desktop:package

. The size of resulting .app file is 104.5MB. I’m on macOS 11.5.1. Why is the application large for such a simple example project?

What would make it possible to debug Compose for Desktop apps on IDEA?

I’m fed up with this issue When I make any change to Coomposable function bodies which call this Composable and run to android my device AS doing something wrong and at runtime throwing this error

after migration to 1.0.0-alpha1-rc1 a strange bug appeared First screenshot - 0.5.0-build270 Second screenshot - 1.0.0-alpha1-rc1

We are choosing between Electron and Compose Desktop. What thing I feel will be missing is powerful charting libs. Web has powerful libraries like D3 and other derived from it. Are are great options for compose in that area?

Is there a layout that my three elements use the full width but the left and right have the width with content wraped and the mid will fill the space left in the middle?

@Nik I tried the approach you suggested of copying resources out of the jar into a folder so that they can be accessed outside of the jar. This works when the app is in the build folder, but when it’s in the

/Applications

folder, it has an issue when trying to copy to the

My <http://App.app/Contents/resources|App.app/Contents/resources>

dir.

java.nio.file.FileSystemException: /resources: Read-only file system

Does anyone have a recommendation of where I should be saving these resource files?

e: /home/atsushi/.gradle/caches/jars-8/e51b24e2bc2b3d6212beb0e53efc315d/compose-gradle-plugin-1.0.0-alpha1-rc1.jar!/org/jetbrains/compose/desktop/DesktopExtension.class: Class 'org/jetbrains/compose/desktop/DesktopExtension' was compiled with an incompatible version of Kotlin. The binary version of its bytecode is unknown, expected version is 1.0.3

Which kotlin version makes it work with compose-gradle-plugin:1.0.0-alpha1-rc1 ? I got this error with kotlin-gradle-plugin:1.5.30-M1 which I assume is the latest.

There is some bug with VerticalScrollbar in AlertDialog. Buttons overlap it at the bottom. And Text at the top is also moving, when it shouldn't.

I would like to take a screenshot in desktop app as a part of jvmTest. In androidTest I can do that with takeScreenshot method from uiautomator.UiDevice. Any hint how I can do that without spinning up an Android emulator (I have both targets …)?

hi when there will be binary compatibility with jetpack compose? There are some libraries like coil, lottie which we can use in android module

I would like to have a scrollable element for horizontal scoll. I tried the following two code as example and both didn't work. Is there another way to get the scrollable element?

fun main() = Window {
    val stateVertical = rememberScrollState(0F)
    Row(modifier = Modifier.width(400.dp)
        .horizontalScroll(stateVertical)) {
        listOf(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17).forEach{
            val text = "Hello, Desktop! $it"
            Button(onClick = {
            }) {
                Text(text)
            }
        }
    }
}

fun main() = Window {
    ScrollableRow (modifier = Modifier.width(400.dp)){
        listOf(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17).forEach{
            val text = "Hello, Desktop! $it"
            Button(onClick = {
            }) {
                Text(text)
            }
        }
    }
}

Hi how can we call fast*** util. functions in common module?

Trying to make a go game board. Wonder if anyone here attempted this in compose? I seem to be stuck with the idea of manually drawing the board lines (using canvas API) and then overlaying circular buttons on top. It seems like chess would be easier because each button could represent a board square, whereas in go we play stones on the corner. Anyway, anyone interested or have any suggestions?

calling a java FileDialog works great, unless I'm in a TextField.

val fileDialog = FileDialog(window.window)
fileDialog.isVisible = true

triggers

Hi folks, Compose-desktop has any version that is compiled on top of Compose Android 1.0.0 ? (specially the compiler plugin)

Hi everybody. I’ve managed to run compose-jb todo example but I see that it uses

buildSrc

instead of gradle

includeBuild

. In my pet project I use

includeBuild

and I didn’t manage to setup compose-jb with it. I’ve reproduced the error I get in my pet project with the todo example. There’re my changes: https://github.com/soniccat/compose-jb/commit/cf2dc97e8a42bc1fbd3aa678799537bd5f447921 The full error message is here https://pastebin.com/ghZLKS21 Probably I’ve messed up with gradle… would be great to hear any ideas.

We are happy to announce that Compose Multiplatform went Alpha today. The build

1.0.0-alpha2

is already available in the Maven repo.  While its API is not completely stabilized, we will strive to minimize API changes in future, focusing on stabilizing the framework on its way to beta and 1.0.  We believe that though the current version may have certain issues, it already could be used for early prototyping and PoC preparations of real applications built on Compose Multiplatform technology.  And as usual - feel free to share feedback about Compose Multiplatform, so that we could improve it. Enjoy composing! P.S. Some details about the Release could be found here - https://blog.jetbrains.com/kotlin/2021/08/compose-multiplatform-goes-alpha/

Has anyone managed to render a Preview ? I just tried it with:

I have updated compose desktop from 1.0.0-alpha1-rc4 to 1.0.0-alpha1 and I can't build an executable anymore. When I execute "runDistributable", I have the following error : "Error: Could not find or load main class esources"

The latest JetBrains Toolbox release is now fully made in Compose Desktop (which is awesome). Now, I noticed that the popup window when you click on the tray icon looks very nice and native. How did they manage that? I've tried a lot of things (like undecorated windows with transparent backgrounds), but have achieved nothing. Any thoughts on this?

Which version of Kotlin can I use for the alpha version?

1.5.10

,

1.5.20

and

1.5.21

don't seem to work.

Have a question still about drawBehind, how can I get the same result but draw on top of some content? It seems like when I use Canvas by itself it puts it after the text, but I don't want it to be behind either. I just want directly over the cross but on top

Box {
    Text(
        modifier = if (isVisible.value) Modifier.drawBehind {
            drawCircle(Color.Black, radius = 10f)
        } else Modifier,
        text = text.value,
        color = Color.Gray,
        fontSize = 30.sp
    )
}
androidx.compose.foundation.Canvas(modifier = Modifier.fillMaxSize(), onDraw = {drawCircle(color = Color.Black, radius = 10f)})

I’m having this error after upgrading to the last version

This morning, on a fresh project with 1.0.0-alpha1, I'm getting:

Could not find androidx.annotation:annotation:1.2.0

Still having trouble with getting Compose Preview annotation to resolve. Added the uiTooling implementation and compose-gradle-plugin:1.0.0-alpha1-rc1, all the stuff I found in the threads above.

I’m trying to make my Compose application self-updating. I’ve never messed with `ClassLoader`s before, but thought it might be possible to do with them.

val jarFile = File("<Path to downloaded jar>")
val classLoader = URLClassLoader(
    arrayOf(jarFile.toURI().toURL()),
    Thread.currentThread().contextClassLoader
)

val myMainClass = Class.forName("MyClass", true, classLoader)
val mainMethod = myMainClass.getDeclaredMethod("main")
mainMethod.invoke(null)

This works until the AWT loop starts and my class loader hasn’t been set on that thread so it can’t find the right class. I’m sure there is a better way to do this. Can anyone point me in the right direction?
