Hello! When mouse btn press on Button, move and release on the same Button it is not treated as click and Button onClick not fired. Sometime when I make mouse click it is not fired due to this behaviour (while clicking mouse has moved a little). Is this supposed to be like it is or it is a bug?

Is there a known good workflow for integrating Mapbox or Google maps into a Compose Desktop application? Looking for a sample, or place to start. Thanks!

Does anyone know what an error like this means? I think it stems from rendering a Lazy Column of composables (Textfields, text, sliders, etc.), but I haven't been able to intentionally reproduce it, nor have I been able to get any stacktraces for it yet. Any help would be appreciated

I tried to experiment with mouse scroll events following this tutorial from JetBrains: https://github.com/JetBrains/compose-jb/blob/master/tutorials/Mouse_Events/README.md#mouse-events But when I build the project all I get is this:

e: …/CmpMapPane.kt: (132, 55): This API is experimental and is likely to change in the future.

How can I get rid of that and get my code compiled. I’ve added

@OptIn(ExperimentalFoundationApi::class)

to the composable function on which I use the pointerInput modifier but IntelliJ is only telling me

The opt-in annotation is redundant: no matching experimental API is used.

I noticed that using a

Slider

within a row does not work if the other elements in the row change sizes (see attached screenshot). Code that demonstrates the behavior

fun main() = singleWindowApplication {
    var zoom by remember { mutableStateOf(1f) }
    Row {
        Text(text = "Zoom = ${zoom}")
//        Text(text = "Hello") // using a "static" text fixes the issue
        Slider(value = zoom, valueRange = 0.25f..1.5f, onValueChange = { zoom = it })
    }
}

Is this an expected behavior or is this a bug that I should report somewhere?

Anyone come across this crash? It happens 100% of the time for one user. They've moved the enclosing folder around and tried running as admin. Error is that

skiko-windows-x64.dll

is missing dependencies. They're on Windows 7 but have a x64 OS.

why are some alphas pushed to maven central and others not?

Does anyone have any information on autoupdaters w/ CfD? I'm fairly new to the process, but I'm trying to add autoupdating functionality to my application, autodownloading new releases. Would I have to create a main JAR file that would replace the code, or something else...? It's a relatively small app so I think replacing everything may be fine

Hello, I want to do some 3d drawing in my app and I don't know what to use. I tried using https://jmonkeyengine.org/ but I couldn't make it work. I saw the example with

lwjgl

, but I think it's too complex for me, I want to show a

3D

view only in a preview screen. I tried using

vtk

with java wrappers, but I can't make that work either(on my machine at least). I was thinking about using https://github.com/google/filament but I don't know if it is supported, saw some threads from @romainguy about this, but haven't found an answer

I experimented a bit with mouse-wheel scrolling and I am wondering why it is so different from pre-existing solutions (e.g. JavaFX). 1. Why is the sign of scrollDelta.y just the opposite of the one from JavaFX. 2. Why is the value so different? A single mouse-wheel tick is +-0.1 for Compose but +-1.0 for JavaFX. 3. What is the meaning of the scrollDelta offset values? 4. Is there a way to distinguish text scrolling from pixel scrolling? 5. There does not seem to be a possibility to distinguish different event sources. E.g. it is important to distinguish between a scroll event from a mouse-wheel or an attached trackpad because you might want to perform a different action depending on the source. 6. Is it possible that not all the associated API is accessible from commonMain?

Does anyone know how I can make my compose app handle URIs? I want deeplinks to open my app and get the query parameters from it I want my browser to open my app for links like

my-app://...

Hey - I have a JVM desktop compose application, that is interacting with a kotlin native executable. Right now the Kotlin native is outputting json to stdio, and the jvm desktop app is watching the stdio and reading it in. The lag that i’m seeing with this method is several hundred millis surprisingly. Is there another communication method that you might recommend that would be faster?

Inside

"src/jvmMain/resources"

I’ve my resources. If I run

./gradlew run

the app launches and I can use them, example:

playSound(File("src/jvmMain/resources/sound.wav"))

. But when I create a distribution or a package those resources aren’t included. I can see them inside

build/processedResources

but not in

/build/compose/binaries/main/app/MyApp.app/Contents/app/resources

. I’ve tried this:

with(project.file("src/jvmMain/resources")) {
    macOS { iconFile.set(resolve("icon.icns")) }
    linux { iconFile.set(resolve("icon.png")) }
    windows { iconFile.set(resolve("icon.ico")) }
    appResourcesRootDir.set(project.layout.projectDirectory.dir(this.path)) //<<<<<<<<<<<<<
}

But with no luck, still can’t “find them”. Funny thing, the icons (

iconFile

) are found and used 🤷‍♂️ Any hint? Thanks. I was looking into this docs.

Are there any Kotlin/Java libraries similar to Pynput? I've put together a simple shortkey program with a GUI written in Python, but I would like to recreate it with Kotlin and Compose.

Which database is recommend to use in a compose-desktop proy?

Anyone has an implementation for

ExposedDropdownMenuBox

for desktop? looks like

compose-jb@1.1.1

only has this for

androidMain

How can I run the

VideoPlyer

demo in a macbook M1? Even having VLC installed I get this error:

dlopen(/Applications/VLC.app/Contents/MacOS/lib/libvlccore.dylib, 0x0009): tried: '/Applications/VLC.app/Contents/MacOS/lib/libvlccore.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))

Is there a way to handle when a window is unfocused?

How can i make function with a different implementation on windows than in linux. Is this the use case for expect/atual?

Is it possible to draw a Composable to e.g. an

Our plans regarding 1.1.2/1.2 are changed, and scope of it will be revised.

@Igor Demin - is this something that you can comment on in a bit more detail?

Hello, i’ve been seeing more and more crashes on Mac OS when i have my application running idle (open but not actively being used). The error is

Font transform has NaN position

. Before i look into filing a bug report, has anyone experienced this?

Is there currently any way to detect if an element is within the visible viewport?

Is there a way to fix this? I've tried clipping, not clipping, nothing seems to work. The background color is leaking out the corners of the border. Also tried clipToBounds(). Using version 1.1.1.

Box(
    modifier = Modifier.height(48.dp)
        .fillMaxWidth()
        .background(color = backgroundColor, shape = RoundedCornerShape(4.dp))
        .border(border = if(selected) BorderStroke(4.dp, Color.Black) else BorderStroke(0.dp, Color.Transparent), shape = RoundedCornerShape(4.dp))
        .clip(RoundedCornerShape(4.dp))
        .selectable(selected = selected, onClick = { onClick.invoke(index) }),
    contentAlignment = Alignment.Center
)

So, now that we’re using compose on the desktop (JVM), we have the usual Java problem of first-time class loading taking a long time, which looks bad in a desktop app. Is there a good solution for this? So far my best is to load all the classes given by Guava’s

ClassPath.allClasses

, but that seems a bit much.

As part of a spike to study the viability of using Compose Desktop for an IOT project, I have just managed to run a compose window with an embedded CEF Chromium browser in Ubuntu arm64. Next step is getting rid of the window manager and if possible of X11. I have no idea of how to start doing that. Any guidance / advice /sample project would be welcomed. :D

Hello, does anyone know why I get this error when I try building my project? The imports work in the editor and I can run the code when using compose for desktop, but android fails to build:

I used Compose JVM to create an image generation server, which is significantly faster than HTML Image generation methods I’ve found for servers. I wasn’t able to get compose running on Alpine Linux via Docker. The JVM was crashing. I was however able to get it running on Ubuntu Linux via docker just by adding the packages

libgl1-mesa-glx

and

libfontconfig

. Image generation is slower on a server than a laptop, which is a little unexpected, but I suspect it’s because all rendering is being done with a CPU, and no GPU. As things stand I’m generating simple 4k images in ~300 - 500 millis.

I'm trying to place some compose UI on top of a JCEF browser shown on a

SwingPanel

. Unfortunately it does not work because as stated in the documentation, SwingPanel is on top.

The Swing component is placed on top of the Compose layer (that means that Compose content can't overlap or clip it).

Any ideas of how to circumvent this limitation?
