There is any API to listen to keyboard events in background in Compose Desktop? example: for opening the window with a shortcut?

Is there a way to listen to focus changes of the window? I tried

val windowInfo = LocalWindowInfo.current
LaunchedEffect(windowInfo) {
    snapshotFlow { windowInfo.isWindowFocused }
        .onEach { println(it) }
        .launchIn(this)
}

but it only prints

false

once and that's that.

I have the following code and for some reason

LazyColumn

is not scrollable, it gets cut off. I will post a screenshot in the thread. Notice that I've added button and it is positioned correctly, so Box constraints are correct. I've added

PaddingValues

and now it's obvious that

LazyColumn

is not meausred with window's height. This is

1.0.0-beta5

. Do I do something wrong? Similar code works in Android afaik.

Window(onCloseRequest = { exitApplication() }) {
  MaterialTheme {
    Box(modifier = Modifier.fillMaxSize()) {
      LazyColumn(modifier = Modifier.fillMaxSize(), contentPadding = PaddingValues(30.dp)) {
        items(80) { index -> Text("Hello $index") }
      }
      Button(onClick = {}, modifier = Modifier.align(Alignment.BottomStart)) { Text("Hello") }
    }
  }
}

Hello all! I have a desktop compose project with a kotlin and java source set in the main module. I think I may have an issue with the java source set, or with packaging it in some way. When I run the app from MainKt everything works fine. But, once I build it and create a distributable image, the app runs until I press a button that calls a static method from the java source set and the app just freezes. No errors, no exceptions. Anyone know what could be the problem? The java class in question has a static method that has imports from

javax.smartcardio

, which could be causing some issues since its supposed to interact with usb ports and whatnot.

[✅ solved] Where is the sqlite database saved when using

SQLDelight

for JVM in Compose desktop? I can't find the database in the project folder

Is there an

Decompose

example app (multi platform) that implements 1. Platform specific actions like importing an image file (file explorer in desktop and content provider in android) What I'm having difficulty is how should I let the platform know a platform specific action has to happen? The

todo app

example, even though display's decompose's navigation prowess it can be quickly glazed up on with very little multi platform specif code. Edited This looks like something for MVI? Well following decompose for multi platform makes your app MVI by default I guess.

Hey guys, Is there any API to listen for window resizing ? To know whenever the Width/Height of a window modifies?

Is the compose runtime artifact compatible with iOS targets?

There is anyway to compile locally Skiko from a branch and use it at Compose JB project (without building the Compose JB locally)?

Hello, when i use kmp expect fun and put a modifier as default param, but it run with a NPE，Anyone know why？

Hello! Can I use WindowState to set initial size of application window, or should I be using a different code now? Thanks.

Hello 🙂 Did anyone use a bytecode shrinker to improve the sizes of native distributions? If yes is it worth the size gain and could you share your setup?

ummm, I didn't mean this code to be this rude

Did you try setting jvm target to 1.8 in gradle (for both, kotlin and java plugins)

I think this paragraph was my real BING moment! "In Compose's declarative approach, widgets are relatively stateless and do not expose setter or getter functions. In fact, widgets are not exposed as objects. You update the UI by calling the same composable function with different arguments. This makes it easy to provide state to architectural patterns such as a 

ViewModel

, as described in the Guide to app architecture. Then, your composables are responsible for transforming the current application state into a UI every time the observable data updates." And again here further down: "Recomposition: In an imperative UI model, to change a widget, you call a setter on the widget to change its internal state. In Compose, you call the composable function again with new data. Doing so causes the function to be recomposed--the widgets emitted by the function are redrawn, if necessary, with new data. The Compose framework can intelligently recompose only the components that changed." I'm only an amateur, but I'm loving this a lot! 🤓

If I use the latest compose-jb version, say v1.0.0-beta6-dev446 , and use it for Android, is it actually newer than the google's mainstream v1.0.1?

I want to build windows program on Linux machine. I added

Hello! I'm looking for functionality like this: https://developer.android.com/jetpack/compose/gestures#multitouch But in Desktop Compose, to handle Zoom, Pan, Rotate, etc, using a mouse input. Any suggestions? Thanks!

How can you run Composable non ui tests?

implementation(compose.uiTestJUnit4)

needs skiko, but I only want to test @Composable without ui.

Hello! I can't seem to find a way to detect the mouse wheel rolling, to create a zoom function. Thanks!

Does anyone have a view on what the coolest looking Compose Desktop app is, at present? I'm playing with the examples but some of them are kinda broken/buggy/not that cool looking.

e.g. the widget gallery appears to lack scrollbars.

I sort of vaguely recall someone made a music player /spotify type app?

Hi, maybe kind of a noob question, but in android we use viewmodel to hold data/states, here in compose for desktop what is the recommended thing to use ? if already asked or not related here, I'd like to atleast get the old answer or docs so I can get read it. Thanks in advance!

Just out of curiosity: Is compose using Swing because it already works? I've been a Swing developer before but would like to get away from it

I'm a little confused. I want to use a boolean value from my model to show/hide some things on my UI, but it doesn't work if I have a TextField in my set of composables. The state won't change for any of the composables in the block

I was building DMGs compatible with intel macs on an arm mac build machine. All our builds after we upgraded to Compose Beta no longer work on intel macs when they are compiled with an arm mac (they work fine when compiled with intel mac). Was this an intentional change? Can we compile a DMG for intel macs on arm machines any more?

Anyone with this issue?

Yes there is. You have to install the IntelliJ plugin to get it. For me I couldn't make it work but the feature does exist. It'll probably become more robust in the coming months.
