I created a brand new desktop compose app using IntelliJ/IDEA 2020.3, on macOS without changing anything from the default demo app. run and package works fine. I then copied the folder to a Windows 10 machine and it doesn't work -> getting this error: PS D:\Work\desktop-compose-test> .\gradlew.bat run

> Task :run
SkIcuLoader: datafile missing: C:\Program Files\Zulu\zulu-15\bin\icudtl.dat.

Any idea?

0.3.0-build138 broke something for me: https://github.com/PaulWoitaschek/Chess/commit/60c94d73ecefd770f14a9a77044bae4f4fca1141 When I bump this to 138, 139, 140 or 141, it runs in some kind of recursvie compose loop and the game stays white while I can see in the logs that its recomposing in a loop

Hey folks, I just wanted to give Compose a try using IDEA 2020.3.1 (Apple M1) and Azul Zulu Community version 15.0.1. I've followed the project creation from within the IDEA. then running the application leaves me with the errors below. Do I need to add any ARM-specific files to make it work with Apple Silicon?

Hi, i would like to ask is there any plan at all (and if any, some roadmap for it) to support ARM architecture? My company want's to migrate old JavaFX application that runs on RaspberryPi to something more modern and currently we are divided between Flutter and QT. We would love to use Jetpack Compose since most of us know Kotlin and play with compose for some time 🙂

short question: how do I get horizontal/vertical scrollbar to get displayed ... I can scroll, but the scrollbar itself is never visible:

@Composable
fun AppRight(modifier: Modifier = Modifier) {
    Box(modifier.fillMaxSize()) {
        val verticalScrollState = rememberScrollState(0f)

        ScrollableColumn(scrollState = verticalScrollState) {
            LoremIpsum()
            LoremIpsum()
        }
        VerticalScrollbar(adapter = rememberScrollbarAdapter(verticalScrollState))
    }
}

In Jetpack Compose 0.3.0-build143, androidx.compose.runtime.onCommit has vanished from the runtime. Was this intentional?!?

If you were curious, how to create application with the startup splash screen, see https://github.com/JetBrains/compose-jb/blob/728b4d5f762f5d901a869824c4b5a2da8b516[…]geviewer/desktop/src/jvmMain/kotlin/example/imageviewer/Main.kt

I did an app Layout purely with (Scrollable)(Column/Rows) inside

window { MaterialTheme { Surface { DesktopTheme { Scaffold(() } } } }

now when I start Mouse selecting Text (e.g. at the top of the rightmost column (see screenshot) Text that is in other columns at the same "height" gets also selected. In the Screenshot I only selected the Text of the rightmost column. But the whole center column and also stuff on the same "height" in the left column gets also selected. (Even if I open the Scaffold Drawer and start Mouse-selecting text in it, text in the bodyContent columns gets also selected) Is this problem "known" or am I doing something wrong ?

In compose version 0.3.0-build143 the onDispose function is replaced by DisposableEffect where a key is required. But in my use case i just want to do some cleanups when the composable is removed from the view tree. How can i implement this with the new API?

Hello everyone. Started a project, which includes desktop client. 10 seconds to decide the framework: is there any solution made by JetBrains? Compose? I take it, those guys know how to write things.

what is the eventual way to display a popup "panel" under/beside an arbitrary @Composable. There once was a DropdownPopup but it was removed as I read. is there a "current" solution to do an arbitrary Popup directly beside a @Composable ?

Hi I'm getting this error: https://kotlinlang.slack.com/archives/CJLTWPH7S/p1611863285394700?thread_ts=1611863285.394700&cid=CJLTWPH7S My current setup is: * android app with google libs * using a library (made by me, so I can change it) that is android+desktop, it uses jetbrain libs

@Arkadii Ivanov Maybe Its related to decompose ?

The packageMsi is soooo close to finally working. I was able to finally install it, but when I run it, I get a popup, "Failed to Launch JVM." When I try to run the uber jar, I get "no main manifest attribute, in <my jar>" We're soooo close haha

I make a simple compose application (LazyColumn with Text, Buttons and LinearProgressIndicator in the rows). When I make it in Linux everything worked fine. But when I compiled it for Windows on the same computer and run, I got an fatal error in JRE. Compose version 0.3.0-build143. Another Compose application with a more complex interface worked fine with this version of Compose and with the previous ones. I try compile the project with different variants of JDK (liberica-14, liberica-15, adopt-openj9-15). This error occurs in different moments: while changing the progress bar or at the moment of a simple button click... JVM save different report files but they all have the same beginning:

How to find a solution to this problem?

is there something like a SplitPane (having a UI handle resizing width/height of neighbour components)?

Hi, i want to display a small FPS counter when a debugging option is enabled. This is what i did to achieve that. Could somebody review and check if this is ok?

Hey, is there any nice example for desktop-compose in groovy 🙂?

Wow it looks like the slow UI problem on some multi monitor laptop setups is fixed now in 0.3.0-build146. At least for me. 🎉

Hey guys, what happened to the lifecycle functions in the newer builds? I can’t access the usual suspects like onActive, onCommit, onDispose. Were they renamed or discarded?

is there a "DropdownList" alike Component? What I'd love to have would be roughly like this (see below) The list items a) searchable and b ontop of any components that might be below it. Or am I supposed to implement my own Popup? DrowdownMenu? or else?

hmmm, my implementation of a thing similar to aboves SearchTextFieldDropdown: if I put

Column { for (i in 1..100) { Text("item $i") }

inside a `@Composable DropdownMenu()`'s

dropdownContent

the dropdown "disapears" if height is larger than the window height (and I cannot put it into an explicit LazyColumn as

dropdownContent

Clause is already a

ColumnScope

Is this a bug, or am I doing something wrong? (or is DrowdownMenu not meant to show things with height > Window.height?)

how can I focus a Textfield on keyboard shortcut? how can I dismiss a popup on ESC key ? (also if I open a popup on textfield input ending in "\n", I can continue typing into the textfield (which is ok), but textfield is no more receiving Modifier.onKeyEvent()

Hello guys. I am on my first steps on compose development. I have a question that maybe you can help me. When we use Android, we can use intents, navigation component, fragment manager to navigate to the new screens... how we can do this on compose for desktop?

Anyone using

Ubuntu 16.04

?

starting with build

0.3.0-build148

we support signing and notarization of macOS DMG packages in Gradle plugin out of the box. See https://github.com/JetBrains/compose-jb/tree/master/tutorials/Signing_and_notarization_on_macOS. Please let us know how it works for you, and if documentation needs clarification or improvements.

for

gradle createDistributable

(MacOS) I get:

Invalid JDK: /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home/bin/jpackage is not a file! 
Ensure JAVA_HOME or buildSettings.javaHome is set to JDK 14 or newer

do I really need jdk above 11 or just another jdk than adoptopenjdk? also it complains on mac bundleID not present, but I don't get where to put below

macOS

clause in my build.gradle.kts (using latest intellij)

macOS {
    bundleID = "com.example-company.example-app"
}

any ideas?

Hello, is there a way in jetpack compose to adjust the window size to the content size? I tried the onGloballyPosionated modifier, but it only works when the window is already visible. If the window is too small from the start, it takes these values in the modifier. I plan to calculate the window size and adjust the position according to the content size. Unfortunately, it doesn't look nice when the window is already visible and then adjusts itself.

Box(modifier = Modifier.fillMaxWidth().onGloballyPositioned { layoutCoordinates ->
    val manager = AppWindowAmbient.current //AppManager.focusedWindow
    windowSize = IntSize(
        layoutCoordinates.size.width,
        layoutCoordinates.size.height
    )
    manager?.setSize(windowSize.width, windowSize.height)
}) { ... }

Thank you!

Hey folks! We’re excited to see so many people in this channel already – and we’d love to get to know you better! Please tell us a bit about your experience. Where are you using Jetpack Compose Desktop now? ❤️ Pet project 💛 New project at work 💙 Pre-existing project at work 💚 I’m just learning this new technology 🖤 Other We’d really appreciate if you tell us more about your projects or share a link to it in the thread 🧵

@Composable
    private fun emptyIcon() {
        Box(
            boxModifier,
            contentAlignment = Alignment.Center,
        ) {
            Image(bitmap = squareImage, alpha = 0.2F)
        }
    }

Since build 142 I am kinda forced to set

contentDescription

? Kinda confused since it's a

String?

and I am using named arguments... very early here 😄
