    I can't figure out how I'd implement the "tab enters group, arrow keys move focus within group" behavior in my compose desktop application, while still allowing the children to be visible (and focusable) via accessibility tools. I'm talking about the focus behavior that e.g. the room list of Slack/Teams has, or that's typical e.g. in Win32, Qt or Cocoa apps. The samples tell me I'd have to manually wire up all the next/prev/left/right/up/down focus targets, but I can't really know which those are in an individual component. I could disable focus for all the list items, and only enable focus on the parent item, but then I'd also lose most of the accessibility interaction, right?

    Hi everyone, I’ve been working on accessibility with Compose for Desktop (macOS + Windows) and I noticed the following issue: • On macOS with VoiceOver, when focusing a 
    TextField
    , neither the 
    label
    parameter nor 
    .semantics { contentDescription = ... }
    is read aloud. • On Windows with NVDA, the label is correctly read. • For error messages (e.g. “wrong password”), even when displaying them in a 
    BasicTextField
    , they are not announced by the screen reader. They are only read if focus is moved manually (with some hacks). On Android, there is 
    LocalAccessibilityManager.announceForAccessibility(...)
    which allows announcing messages like errors. But this doesn’t exist on Desktop, and it seems impossible to announce such errors today. Is there a recommended way to make error messages (or dynamic text changes) announced by VoiceOver/NVDA on Desktop? If not, would JetBrains be open to contributions in this area? Related issue: https://youtrack.jetbrains.com/issue/CMP-2136 Thanks!

    I'd like to serialize my app state such that upon close/reopen it restores the state as it was left. How would I realistically accomplish this? I tried making a variety of things @Serializable, but a bunch of things like MutableState are not really compatible with this, not to mention I'd have to run a save on a loop rather than after every change to the program's state.

    I'm struggling with something that looks like a bug to me... I have a Compose Desktop app for JVM (
    kotlin("jvm")
    )     Setting the icon like this works:
    Copy code
    windows {
  iconFile.set(project.file("src/main/resources/icon.ico"))
}
    It stops working if I set additionally a appResourcesRootDir:
    Copy code
    appResourcesRootDir.set(
  rootProject.layout.projectDirectory.dir("resources")
)
    The issue: The EXE has an icon, but it's missing in the taskbar. It's the Java Duke there. It only affects Windows. For macOS it still works. How can I fix this? Edit: Nevermind. It's a bug in connect2x/sysnotify

    I am getting a crash with KMP and the Material3 date picker. Pretty easy to replicate - just add 
    val dpState = rememberDatePickerState()
    to any composable function and it will crash during composition - error is 
    Caused by: java.lang.ClassNotFoundException: kotlinx.datetime.Clock$System
    . My project does include 
    kotlinx.datetime
    and I use it elsewhere. The same code works on Android. I can produce different errors by varying the parameters in the call to 
    rememberDatePickerState()
    .

    Hi, I’m trying out Compose Multiplatform Hot Reload in a multi-module project. I’ve got a desktop app module that depends on another module. Hot reload works fine when I change code in the desktop module itself. But if I change code only in the dependency module, nothing happens unless I also change the desktop code (e.g. add a line) so the compiler notices. Is there a way to get hot reload to notice changes in the dependent module directly? Or is this just a current limitation?

    Hi everyone, I am getting a strange configuration error below for my desktop app on windows only (mac/linux fine) - was working fine until yesterday. i am on:

    loadImageBitmap(InputStream)

    Do you guys have some pointers on how to profile a Compose jvm app with YourKit? I'm not sure how to figure out the optimization opportunities for my app - a lot of the methods it's showing are related to coroutines or the compose runtime. Should I exclude these methods from the trace, since they're from the runtime? how do I link back to the app code?

    I've added a 
    ToolTipArea
    to a button on a compose desktop application. It works fine in the running application, but the preview compilation fails - 
    Unresolved reference 'TooltipArea'
    . Is this something I need to do with expect/actual? Or have I found a bug? I've just updated to compose multiplatform 1.9.1.

    Is there a way to speed up start of

    Copy code
    plugins {

    id "org.jetbrains.kotlin.plugin.compose" version "2.2.20"
    id "org.jetbrains.compose" version "1.9.1"

//
fun main(args: Array<String>) = singleWindowApplication {
    AppTheme {
        ...
    }
}

@Composable
fun AppTheme(content: @Composable () -> Unit) {
    MaterialTheme(
        colors = if (isSystemInDarkTheme()) { <-----------------------
            darkColors()
        } else {
            lightColors()
        },
    ) {
        Surface(color = MaterialTheme.colors.background, content = content)
    }
}
    Why is the compose desktop app not reacting to dark mode changes? I'm testing on 
    mac os
    and 
    windows
    , and when I toggle the system setting it does nothing. After restart it picks up the current setting but not during runtime. Is this known?

    Hi Folks. I have question How I could extract glyphs paths as compose paths from fonts using jetbrains skia or even compose . Or its impossible ? I try to load typface with skiko typface but there is no api provided for that so I try TypefaceFontProvider but it does not work the data loaded as byte but when asign it the typface is null .
    Copy code
    val provider = TypefaceFontProviderWithFallback()

val data = Data.makeFromBytes(Res.readBytes("font/cairomedium.ttf"))

val typeface = provider.makeFromData(data)
