Is it possible to detect simple mouse up/down events? I’m wanting to implement a kind of arbitrary drag-and-drop across a window. Items are being positioned globally within a

Box

using

pointerMoveFilter

, but I need to detect down events to focus a single item, and up to drop. However, it seems like using

Modifier.pointerInput { handlePointerInput { ... } }

can detect up/down events, but move events are handled by the child relative to the child, and the parent

Box

never receives those move events until I drop the child

🛣️ Do we have any navigation library available for compose desktop? (like Jetpack Navigation)

TextField missing basic behavior? I might well be missing something myself, because I just started out trying compose-dekstop. I tried the most simple text field:

var text by remember { mutableStateOf("") }
    TextField(
        value = text,
        onValueChange = { text = it }
    )

Things that don't work: DEL key, Pos1 and End keys, text selection using Shift-Left/Right, navigating by word using Ctrl-Left/Right Using latest Kotlin 1.4.21 and org.jetbrains.compose version 0.3.0-build140

Is there a glitch with

FocusRequester.requestFocus()

? Seems like that doesn't work on a

TextField

with

Modifier.focusModifier().focusRequester(requester)

Hi everyone! When I am creating a compose-desktop project through the New project wizard of IntelliJ IDEA, I am missing Compose's sources and documentation artifacts. Is there a way to fix this ?

Any chance of getting a version of Jetpack Compose compatible with the latest Kotlin compiler (1.4.30-RC)?!?

I have a List of Movies (list of movies could be in the 10000s) and each movie has a reviews. There can be hundreds of reviews left on a movie. I know its bad UX/design, but I want to show a list of Movies with ALL of the reviews listed in the same movie card. I'm not sure how to build this, because in the "android" world I would make the Movie List a RecyclerView, and each review section in the MovieCard would be a recyclerView too. But compose doesn't let you do that.

LazyColumn{
    items(movies){
        MovieCard(it)
    }
}

MovieCard(movie: Movie){
    Text(movie.name)
    LazyColumn{
        items(movie.reviews){
            ReviewItem(it)
        }
    }
}

You get an error like this

java.lang.IllegalStateException: Nesting scrollable in the same direction layouts like ScrollableContainer and LazyColumn is not allowed. If you want to add a header before the list of items please take a look on LazyColumn component which has a DSL api which allows to first add a header via item() function and then the list of items via items().

Problem is solved if the LazyColumn in MovieCard just become a Column and I iterate with a for loop. BUT I want that inner loop to be performant and handle being super long. So I don't want a "dumb" Column. I need something that will recycle those ReviewItems.

Have there been any changes or considerations when adding a dependency to a compose-desktop app? i'm trying to add the dependency

implementation("dev.chrisbanes.accompanist:accompanist-coil:0.4.2")

from the mavenCentral() repository. I can see that this file is there on maven central but i get:

CCould not resolve dev.chrisbanes.accompanist:accompanist-coil:0.4.2.
Required by:
    project :

Possible solution:
 - Declare repository providing the artifact

I am trying to create a multiplatform library with both JVM (Compose) and JS target. To do so, I configure it using I am trying to create a multiplatform library with both JVM (Compose) and JS target. To do so, I configure it using

compose.desktop {
    application {
        disableDefaultConfiguration()
        from(kotlin.targets["compose"])
    }
}

With the JS target in legacy mode, everything compile and run just fine. In IR mode I however get the following error:

:compileKotlinJsIr FAILED

e:androidx.compose.compiler.plugins.kotlin.IncompatibleComposeRuntimeVersionException: You are using an outdated version of Compose Runtime that is not compatible with the version of the Compose Compiler plugin you have installed. The compose compiler plugin you are using (version 1.0.0-alpha11) expects a minimum runtime version of 1.0.0-alpha11.

Is there maybe a workaround or is there another option to limit the scope of the Compose plugin?

Hi Everyone! I was curious about compose for desktop. So I wanted to try it for the first time. Right now I'm using IDEA Ultimate Edition, I have chosen Template - Compose Desktop Application and Run the main function which shows "Hello World ". Now the JetpackDesktopWindow shows nothing but a blank screen which struggles to render following these logs below which I understood there is a missing file. Does anyone know what exactly this means?

How do you guys stay informed for new released versions? since the github repo has no releases to watch I find it hard to follow

I try to get a layout of my app for the whole window like:

Column {
    header() { }
    Row {
       leftBar() { }
       centerContent() { }
       rightBar() { }
    }
    footer() { }
}

where header, left/rightBar and footer "eat up" as much height as these components are (means whatever is in in them) and taking the center content "eat up the rest" of available window space. So that if I resize the window, header/footer height and left/rightBar width stay fixed (size depends only on their contents) but centerContent() stretches/expands to get all the new available space on resizing. Whenever I give the centerContent

fillxxxSize()

it also eats up the space of the components below/toTheRight, which then are no more visible. What's the way to have a component eat up all the space there is for it, but no more concerning components below beside it ???

Hey folks, first, the Jetbrains Compose latest builds is sharing the latest Jetpack Compose Alpha artifacts? Second, I'm writing a library for Compose and I want to support Jetbrains Compose and Jetpack Compose with the same artifact, this is currently possible? If not, what is a recommendation to me build a artifact that will support both?

Heads up, something is broken with

Interaction.Pressed in interactionState

+

Modifier.toggleable

in build 141. Getting the smallest repro now and filing a bug.

I’m wondering what is the purpose of

withJava()

and if it’s really needed by compose? • If I use it, then my dependencies are not resolved (their

jvm()

configuration doesn’t contain

withJava()

) • Otherwise I’m getting

Could not find or load main class

(not 100% sure if it’s related, but the package name looks okay, so I’m guessing

withJava

has something to do with sourceSet configuration 🤔)

How could I implement my own

*.compose

library calling native components in C/C++?

Curious, how would automatic updates on a CFD app look like? Any plans to make this available out-of-the-box like Electron? In case, if I were to implement it now, how would it look like. Looking for pointers. Many thanks in advance.

I seem to be getting a

NoSuchMethodError

when trying to add Compose Desktop to my current project. I'm using Kotlin 1.4.30-RC (though this happens with 1.4.20 as well) and Compose Alpha

0.3.0-build141.

what's the supposed way to log something in compose-desktop?

We just implemented support for using Compose for Desktop in IntelliJ IDEA plugins. Take a look at https://github.com/JetBrains/compose-jb/tree/master/examples/intelliJPlugin.

YAY! ComposeDebugDrawer is ready for Compose-Desktop! Thanks @Javier for his work on converting it to multiplatform!

https://github.com/Chozzle/compose-macos-theme Just made this. Useful? I'm imagining doing the same for windows, then desktop UIs could share a lot of code.

How do you run your apps when developing? From command line or Gradle tool window in IDE? I’m having an issue with the latter that it uses a wrong JDK to run it, ending up in error:

MainKt has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

./gradlew run

from command line works fine Where do I configure JDK for the IDE? (IntelliJ IDEA CE 2020.3.1)

what's some easy lib/classes/onBoard support for I18n, any recommendations?

If I use compose-desktop in macOS platform, how can I access macOS framework like PhotosKit to retrieve medias in current device?

Hi @Arkadii Ivanov. I’ve asked many many many questions regarding implementation of decompose library. I’m using jetbrains compose, decompose, mvikotlin, ktor, Now I’m trying to navigate to first screen when api throws authentication error. How can I pass router to api service?

Hey, is it possible to configure a

WindowDraggableArea

in a way that it does not override any possible interaction in its area? For example, if I define a

WindowDraggableArea

and put a

Button

inside of it, it is impossible to interact with the button (the draggable area seems to always be "on top").

Hello, is there a way to have scrollable content that is not clipped to the bounds of scrollable area?
