Hey, is there anyway to set packaging options for Desktop, like with android? I want to cleanup proguard output.

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()
    }
}

👋 I just took some time to get compose hot reload into my 9-5 project since 2.1.20 enabled configuration caching to work with it, unfortunately it seems like within the past few versions a new task has been introduced that looks like

syncdesktopMainApplicationClasses

which takes roughly 1 minute to compile and spits out logs like the following

file '/Users/dmitriytarasevich/.gradle/caches/8.11/transforms/798854b096b6a05b98708be9554307cf/transformed/feature-streaming-pip-jvm-0.7.0/META-INF/MANIFEST.MF' will be copied to '/Users/dmitriytarasevich/dev/fbg-kmp-sdk-alternate/desktop/app/build/run/desktopMain/classes/META-INF/MANIFEST.MF', overwriting file '/Users/dmitriytarasevich/.gradle/caches/8.11/transforms/6431cd6a7bfda5fd687ab9108f3850f8/transformed/foobar-sdk-jvm-0.7.0/META-INF/MANIFEST.MF', which has already been copied there.

for each module we have in the project, seeing as we have around 100 modules this steps takes quite a bit of time. Due to this issue, the inclusion of compose hot reload actually makes incremental builds substantially slower. Please let me know if there is any additional information you need.

According to https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-compatibility-and-versioning.html Compose Desktop supports ARM64 for both Linux and Windows. I have two question associated with that: 1. Can anybody confirm that this works reliably in general. Both at build and execution time? 2. Does building work with the experimental ARM GitHub runners for Linux/Windows for public repositories? See: https://docs.github.com/en/actions/using-github-hosted-runners/using-github-hosted-runners/about-github-hosted-runners#standard-gith[…]-repositories I neither have an ARM box for Linux nor for Windows, so I can’t test it myself but if that works reliably I’d try to support these additional platforms with my software as soon as these runners become available for private repositories too.

Anyone face this issue before? I'm trying to make an api call to my locally hosted server with a self-signed cert... but i get this error.. it works fine in

compose-web

locally..

sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I'm trying to use an unmodifiable TextField to display the contents of a ByteArray, but it seems compose takes about half a minute to calculate the layouting of the text, instead of just having it be the width of the TextField and scrolling all the way down. How can I make this faster?

Now my window feels completely lifeless—no animations, no transitions, nothing. It's even hiding the navigation bar.

Hi all! Does anyone know what may be causing the below error? I have spent quite a bit of time trying to fix it with no luck.

BookListScreenRootTest[desktop] > bookListScreenRoot_displaysSearchBar[desktop] FAILED

Here's more context for my project.

Hi all, does compose desktop support UI automation? Was trying to use windows inspect accessibility tool. It is not able to find the UI elements rendered (It is able to get only the window level buttons like minimise, close etc)

Hi everyone, I’m struggling with a serialization error in my desktop app. The app works perfectly in debug mode, but when I build it for release, I get this error:

⚠️

Serializer for class 'ChatCompletionRequest' is not found. Please

ensure the class is marked as '@Serializable' and the serialization

compiler plugin is applied.

I’ve already marked the

ChatCompletionRequest

class as

@Serializable

. I also followed advice from two StackOverflow links about similar issues (linked below), including updating Proguard rules to keep serializers. Unfortunately, nothing has fixed the problem so far. Here are the StackOverflow threads I referenced: 1. Serializer for class not found 2. Proguard/R8 serialization issue The full code is in my GitHub repository: https://github.com/yassineAbou/LLMS

I am building Apple Silicon + Intel version of my app in parallel But right now they both output their respective dmg to the same file, which is problematic Any way to add a suffix to each one somehow? I tried changing the

packageName

and it does change the dmg file, but it also changes the app name inside of the dmg

Is there any way to configure the Windows start menu name for a CMP app? For Mac OS there's the

dockName

that can be set, but what about Windows and Linux?

Does someone publisher their Compose Multiplatform macOS app (DMG/PKG) directly to the Apple App Store for macOS? I tried this some time ago and it didn't work as Apple did not expect the binary in TestFlight. I wonder if it works now.

was anyone able to package a universal mac os binary?

I have an application that runs in multiple processes, and uses

ProcessBuilder

to start them. When I use

:run

this works fine, but if I use

:runDistributable

the

java.home

directory doesn't have a

/bin/java

to execute. Based on https://stackoverflow.com/questions/71924648/jpackage-for-only-one-application, it seems like I need to tweak how

jpackage

is configuring

jlink

, but I'm not sure where to do that in the

build.gradle.kts

.

how long does it take to distribute your desktop apps? It takes me about 15~20 minutes to distribute Intel + Apple silicon versions of my app on my M3 that includes 2x(build w proguard + wait for notarize + upload to github)

I've added

System.setProperty("compose.swing.render.on.graphics", "true")
System.setProperty("compose.interop.blending", "true")

but for some reason I still can't draw over top of a SwingPanel, am I missing something? For context, I'm using cameraK which displays as SwingPanel+ImagePanel (https://github.com/Kashif-E/CameraK/blob/main/cameraK/src/desktopMain/kotlin/com/kashif/cameraK/ui/CameraPreview.desktop.kt#L62) and I have my code more or less like this:

Box {
    CameraPreview(...)
    Text("Test")
    Canvas {  /* Draw overlays here, also tried Modifier.drawWithContent already */ }
}

Hi everyone, In a library, I need a reliable way, at runtime, to know whether the host application was started via classes on disk (

gradlew run

) or via packaged JAR (

gradlew runDistributable

). Does the Compose plugin expose any flag or API that I can check from within the library? Thanks!

Hello, is it expected that

ImageComposeScene

renders one frame late, or just renders wrong? I am using this composable where I call

render

repeatedly on the same

ImageComposeScene

, but with ever increasing

nanoTime

values, and I only get the correct render if I call

render

a second time, which is quite of a dirty workaround.

@Composable
fun JustFrameNumberComposable() {
    val frameNumber by produceState(0L) {
        while (true) withFrameMillis { frameTimeMillis ->
            value = frameTimeMillis * 60L / 1000L
        }
    }
    Text("Frame number: $frameNumber")
}

I am not up to date with all that has been written here, so excuse me if I'm asking something that's been covered 😛 TL;DR - Mouse events lost if inside window bounds on startup. I have a KMP/CMP targeting all platforms - in my desktop version (Debug at least) if I enter the window of my app during startup all of the following mouse events gets lost. This is fixed by using the Hot Reload Tooling window's "Clean Composition", or just restarting the app and making sure I don't have my mouse where the window will appear. Has anyone else seen this issue? I don't remember having the issue before enabling Hot Reload, so it might be a baddie. compose: 1.8.0 compose plugin: 1.8.0-rc01 kotlin: 2.1.20 (plugins [kmp, jvm, compose] same version) compose hot reload plugin: 1.0.0-alpha09

Is there a way to configure Compose Desktop to set a system environment variable? Specifically the

LD_LIBRARY_PATH

environment variable on Linux.

Is there a way to load wkwebview on compose desktop if we are on mac platform

I'm working on autocomplete for a Compose for Desktop mini-IDE using a DSL I designed. When a DOT (.) is typed after a property or class it is supposed to pop up a context menu with the members (properties and functions) in the menu so they can be easily selected with the keyboard or mouse. You see this feature in IDEs like IntelliJ IDEA, Xcode and VS Code. Thus far I haven't been able to get the popup (context) menu to appear with it's upper left hand corner touching the DOT. The menu works, but it is never in the correct position. The coordinates are aways off. The menu displays farther down (down and away) from the DOT if your DOT is typed toward the viewport's bottom, and up (over) the DOT if you type it toward the viewport's top. Using X / Y coordinates with offsets doesn't work and neither does using rows and columns. Margins are built into the calculations. All the units are correct. I've been working on this along with Claude and other AI's. Nobody can figure it out. There seems to be a serious bug or bugs in one of the (outside) supporting components, either in the coordinate calculations, units or something adjacent to them. Has anyone encountered this problem?

Does anyone have an idea on how to add context menus to part of an

AnnotatedString

? When a link is clicked, I want to open the associated context menu. Currently, I'm using a

DropdownMenu

that opens in an arbitrary location, which isn't great.

How do I fix error popups being empty?

Hi all, I can’t seem to figure out how to get rid of this gradient banding (see screenshot). I’m using

Brush.verticalGradient

and driving myself crazy trying to figure this out. Anyone have any ideas?

Hello, I'm getting this surprising

ArrayIndexOutOfBoundsException

when

ImageComposeScene.use { … }

exits. Could it be caused by Compose Hot Reload, or is it something different? This is with Compose Hot Reload 1.0.0-alpha09 and Compose 1.8.0-rc01 on macOS.

I have an existing desktop utility app that uses JavaFX for the UI. I would like to try converting it over to compose to see if it's a good fit. I did that several years ago with another app, and I remember it being rather simple, but it appears things have changed significantly since then. I'm not interested in multiplatform support as this will never run on anything other than the desktop, but all the documentation seems to be either for Android alone or for mutliplatform. Is there documentation somewhere I'm missing on how to do this? I swear there used to be a page about how to add compose-desktop to an existing app, but I'm having trouble finding it. There isn't even a template anymore for desktop only, which I'm almost certain there used to be.
