I'm looking to introduce compose for desktop into a new project I'm working on. I have all of the code migrated and it works already. I know the age old question "Is this ready for production" is highly subjective, but my team is more curious about what types of errors this may introduce. For example, the team is a little bit afraid about using a slightly modified version of compose, but I told them it's the same compose with a few things built on top of it. I tried finding some documentation to prove that "compose for desktop IS compose, just with a few additions" but no luck on the project page or repo. 1. Am I right in my explanation? i.e. "compose for desktop IS compose, just with a few additions" 2. If so, is that written anywhere? 3. What sorts of problems can my team expect my adopting compose KMM instead of just android compose? All of these questions are with the premise that our android team has 0 intention in shipping a desktop app, we just want faster feedback loops and want to use CfD for that purpose.

I think one ugly thing is that Compose for Desktop

Image.makeFromEncoded()

as well as Android

contentResolver.loadThumbnail()

give you a

Bitmap

, but Compose Image needs an

ImageBitmap

and as far as I can see the implementation of the extension

asImageBitmap()

is on both worlds a really expensive conversation. 😞 Why isn't there a way to directly load an ImageBitmap if that's the needed format? 🤔

Is there a way to execute an action when the window app (created by

Window(...)

function) is closed ?

Is it already possible to change the text "MainKt" in the top left corner on MacOS so something else?

What's the current status about notifications on Linux? I've stumbled across https://github.com/JetBrains/compose-jb/issues/65, but it's more about the tray icon and some infos are older. Should the native notifications work right now? My current status: I tried it on my Ubuntu 20.04 (with gnome shell 3.36.9) and they aren't shown. Based on dbus-monitor they also aren't send to the OS. Tested it with the "old" version with

Notifier

and the experimental API with

TrayState

. Both with

0.4.0

and

0.5.0-build225

.

fun main() = Window {
    val notifier = Notifier()
    val trayState = TrayState()

    MaterialTheme {
        Column {
            Button(onClick = {
                notifier.notify("Notification Notifier", "Hello there!")
            }) { Text("Send via Notifier") }

            Spacer(Modifier.height(8.dp))

            Button(onClick = {
                trayState.sendNotification(Notification("Notification TrayState", "Hello there!"))
            }) {
                Text("Send via TrayState")
            }
        }
    }
}

Is there any news of the jetbrains team working on compose for ios? I remember seeing something a month or so back of the compose compiler being able to work on native. I’m curious if it’s a platform that’s being worked on yet.

Hi all, I am currently working on the desktop app using Jetpack compose. One of the requirements is to get talkback reading the components (description) loud for people with sight issues. I tried to use semantics and set contentDescription as described: https://developer.android.com/jetpack/compose/accessibility, but seems like it doesn’t work for me. I am working on Mac and when I enable VoiceOver, it reads only the name of the app, when app is started or in focus, but it doesn’t focus any component from the app except the main window. I am not sure if this is a bug, or I just don’t know how to set it up, but any help is more than appreciated. If there is a working sample somewhere, or anything I can use as a reference, it would be really great. Thank you very much in advance.

✅ [RESOLVED] Is there any way to set min window size?

Is there anything similiar to

LocalView

in compose Desktop ? I am trying to have a code like this in place:

LocalView.current.let { IntSize(it.width, it.height) }

So is there a way to get some kind of preview of the UI without restarting it all the time?

I’ve installed the plugin but I cannot use the @Preview-Annotation nor do I see the preview icon:

I just copied the solution for VerticalScrollbar solution wie Kotlin/Native from one of the samples and noticed that it's almost identical implemented in a lot of examples. So I wondered why this isn't part of the normal runtime? Or is this already planned? I'm talking about this:

@Composable
expect fun VerticalScrollbar(
    modifier: Modifier,
    scrollState: LazyListState
)

@Composable
actual fun VerticalScrollbar(
    modifier: Modifier,
    scrollState: LazyListState
) = androidx.compose.foundation.VerticalScrollbar(
    rememberScrollbarAdapter(scrollState),
    modifier
)

@Composable
actual fun VerticalScrollbar(
    modifier: Modifier,
    scrollState: LazyListState
) = Unit

Is it possible to use the latest jb-compose plugin without pulling in the web support? (It's not compatible with my JS target)

Hello everyone, is there a way or workaround for modifying the mouse pointer when hovering over a

TextField

? I found the

Modifier.pointerMoveFilter

for detecting mouse hovering, but I cannot find any way for modifying the mouse cursor appearance. This would be useful for elements like `TextField`s and `Button`s but also for games and playful UIs (desktop and web) where they want to provide custom cursors.

I'm looking for a ViewPager like https://google.github.io/accompanist/pager/ that also works for Compose for Desktop in a KMP project. Can someone recommend a solution?

I'm confused about the Window size Parameter... I want to open my Windows in Full HD, but the Window has a completely different size... ?

Hi, I have a doSomeHeavyStuffs() function triggered via onClick of a button, which I want to display a progress bar while it is running. I added of mutable isLoading state, and then write something like:

if (isLoading)
   CircularProgressIndicator()

Then I set isLoading before and after doSomeHeavyStuffs(). But it doesn't work because I suppose the doSomeHeavyStuffs() function is running in the UI thread. Am I supposed to run it in a separate thread? How do I do it in Jetpack Compose?

Is there a way to determine the DPI of the monitor where the Window is displayed? This gives only the scale factor:

window.graphicsConfiguration?.defaultTransform?.scaleX

Say I want to build a ruler composable that displays a box that's exactly 10cm long.

How do you write tests in a Compose-Desktop app ? Is it possible to simulate button clicks ?

I'm trying to sign my mac app, and "[(My Cert Name)]: no identity found"

Hi, I don't know why but when using the ExperimentalComposeUiAPI, when taping on the

TAB

key, I get this error

Exception in thread "AWT-EventQueue-0" kotlin.UninitializedPropertyAccessException: lateinit property layoutDirection has not been initialized

And it crashes (full stacktrace in thread)

How do I get access to the task createDistributable of Compose to add a dependency task? I tried

tasks.named("createDistributable")

in gradle build file but it's not found?

How can I use the

Preview

annotation in build 245 ?

I'm running

[compose-jb/examples/codeviewer] $ ./gradlew :desktop:run

and getting

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: /[...]/libskiko-linux-x64.so: libGL.so.1: cannot open shared object file: No such file or directory

READMEs don't mention anything about requirements and couldn't find "libGL.so.1" in the repo or this channel. Quick google search doesn't help either.

I'm getting the following socket timeout exception on all HTTPS connections when I run my app from the MacOS app bundle created by

./gradlew createDistributable

, but not when running it by clicking the Run button inside IDEA or from the CLI with

./gradlew run

. What might be different between those environments? (fuel is in the trace for context, but I ran into similar issues with okhttp3)

is it just me, or does the

takes forever to even just gradle sync?

Hello, I just have a little question. I'd lke to display a column with a button above a text and a switch. But you can see on the image that result is ugly... How can I make the components stacking each other without overlap ? And how can I display the full text ? I join the code for that part in a thread. Height of the background row is 100 dp.

What version of compose desktop is for 1.5.21?

Starting to move some of my Android Compose code over to a common code base and trying to use jetbrains compose. Can’t find a few classes like Dialog, I see some dialog specific code in org.jetbrains.compose.ui:ui-desktop. Even when I specify it as a dependency, it doesn’t seem to show

Is there any way to have a live interactive preview.
