Feature request for the Compose Preview plugin: "Refresh Preview" button in the Preview panel that re-executes the last run preview task. Purpose: Shortcut that would prevent a lot of scrolling. Current workflow is to edit a composable, then scroll to the preview function and click Preview, then scroll back to the composable to edit as needed, rinse and repeat.

Hi, how can I create a new separate Window ?

Hello again all! Maybe I'm just tired seeing it's 2am, but I can't find any reference online to show me how to send simple character data output to a COM port from my CfD program on Windows. Any tips appreciated! Thanks.

Is there a ConstraintLayout Flow / flexbox like composable for CfD?

Hey, is it possible to have a TextField required to be filled ?

In IDEA, when I navigate to the source of say

singleWindowApplication()

I end up in artifact

org.jetbrains.compose.ui:ui-desktop:1.0.1

and a file

androidx.compose.ui.window.Window_desktopKt.class

. Now I thought the sources for that would be somewhere in https://github.com/JetBrains/compose-jb but I cannot find it there anywhere. Can anybody enlighten me where the sources actually are?

How can we navigate in compose-desktop? Is there any library or the mobile one is used

Should I be updating to v1.1.0-alpha1-dev550 or v1.0.1 I guess my question is moreso. Is 1.0.1 using jetpack compose 1.0.5, and it 1.1.0-alpha using jetpack compose 1.1.0-rc01?

Is there any switch to enable layout bounds debugging where the whole app starts looking like a wireframe?

Hi, on native distributions, I am not able to read/write files on system. Works with kar though. Seems like some permission issue. Is there anything extra which I need to do to make it work?

Is this normal for CfD apps? The drop is when I quit the app.

Just curious, in compose-desktop do we have a local database like

room

? I think other desktop app uses remote db for their apps, no?

Our signed release builds started failing ever since upgrading to Kotlin 1.6.10 and Compose 1.0.1. I filed a ticket around it. The error seems to be happening with jpackage, and it’s giving no useful information. https://github.com/JetBrains/compose-jb/issues/1689

I have a data/state question. In my business layer I fetch data-points from a webservice and synchronize a local db. I have a listener API where I can execute code every time a new datapoint is ready. All this happens in the

<http://Dispatchers.IO|Dispatchers.IO>

coroutine scope. Now, since I'm a compose noob, I have a mutable state list, where I append the datapoints. I rarely get a

ConcurrentModificationException

exception which I guess is because the list is modified in the IO scope and read in the UI by compose. I read that one solution is to basically use a mutable state of an immutable list and assign a new list. That sounds a lot like I don't want to do this. Isn't there a better way to have a long list of datapoints that I can update from the IO thread?

Hello ! I'm having an issue with IntelliJ 2021.3.1, when adding KMP 1.5.31 + Compose 1.0, dependencies are not properly indexed. Looks like simply removing the plugin fixes the indexing. I've tried re-installing, Repair IDE, rebuild, invalidate cache & restart, ... in vain so far. Any idea what could create this issue?

Hi, i have created a simple image preview, that shows an image and a slider to visually compare images. But it's not performing well (slow). Can you see at the code and suggest a better approach?

@OptIn(ExperimentalComposeUiApi::class)
@Composable
@Preview
fun ImagePreview(args: Array<String>) {

    if (args.size != 2) {
        Text(text = "Usage: app image1 image2, args:${args.size}")
        return
    }
    val bitmap = loadImageBitmap(FileInputStream(args[1]))
    val bitmap2 = loadImageBitmap(FileInputStream(args[0]))
    var mousePos by remember { mutableStateOf(IntOffset(320, 0)) }
    Box(
        modifier = Modifier.background(color=Color.Gray).fillMaxSize()
        .clickable(onClick = {
            println("click at $mousePos")
        }).onPointerEvent(PointerEventType.Move) {
            mousePos = IntOffset(it.changes.last().position.x.toInt(), 0)
        }
    ) {
        Image(bitmap = bitmap, "kotlin", contentScale = ContentScale.None, modifier = Modifier.fillMaxSize() )
        Box(modifier = Modifier.fillMaxHeight().fillMaxWidth()) {
           Image(bitmap = bitmap2, contentDescription = "bla", contentScale = ContentScale.None, modifier = Modifier.fillMaxSize().clip(MyShape(mousePos.x)))
        }
        Box(
            modifier = Modifier.width(4.dp).fillMaxHeight().offset { mousePos }.background(color = Color.Red)
        )
    }
}

class MyShape(private val maxWidth: Int) : Shape {
    override fun createOutline(size: Size, layoutDirection: LayoutDirection, density: Density): Outline {
        return Outline.Rectangle(Rect(Offset(0f,0f), Size(maxWidth.toFloat(), size.height)))
    }
}

How do you handle tooltips in a multi-platform project? I have a project where I would like to show tooltips in the desktop variant but not in the Android variant. In order to show a tooltip I have to wrap the relevant content in a TooltipArea but this code then won’t compile for Android where TooltipAreas are not supported. I can work around this by writing my own wrapper via expect/actual but is that really necessary? Isn’t there a more elegant solution?

How can I get rid of this error in the editor window. I have a multi-platform project and when I use

expect

somewhere I get the following error when I open the relevant file. Funnily the project builds and runs just fine and does what I

expected

it to do.

Is there way to know when user has finished selecting say an accented letter (when using for example

TextField

). Looks like, when long-pressing, we get

onValueChange

for the non-accented version first and then again when user picks one of options shown

Does anyone here have experience publishing Jvm apps (or any non-Xcode app) to the Mac App Store? I am working on a PR for Compose (https://github.com/JetBrains/compose-jb/pull/1613). Apps can be uploaded (and I think published) to the App Store, but there is still an issue with TestFlight. See screenshot. Any ideas?

Coming soon in Aurora 1.1 - the breadcrumb bar component

Hey folks, Do all three Compose ui libraries (Jetpack, Desktop, Web Compose) have different foundation implementations? EDIT: Remove Compose for Web from that equation, I just noticed that it has a very different implementation from its two counterparts. I’m thinking about writing a simple graphing library and trying to see if there’s a way to avoid having separate projects for all three the two since it’s just UI code with some light modelling that should - at least in theory - be identical across all both platforms. (this may yet prove itself a folly of course) Sorry for any silly questions, this is the first time I’m having to think about deploying a library to three two similar implementations of a given technology. 😄 Thanks for any eventual answers.

So, I can't help but notice that

compose-jb

repository now has an example for using common widgets on web canvas (using wasm) and on UIKit on iOS?? https://github.com/JetBrains/compose-jb/tree/master/examples/falling-balls-mpp/src

👋 I think the AlertDialog (which is experimental yes), have a little

shape

issue. It’s relying on

Surface

which, by default has a RectangleShape. Doesn’t really matter what we put in the

shape

parameter of the AlertDialog then. Should I file an issue on gh? (see the grey rectangle corners on my screenshot) edit: sorry for the colors, sorry for your eyes 🙈

Hey everyone, what do you use for navigation in your desktop apps?

Also, is there a way to combine pan and rotate animations? I'm using coroutines to

animatePanBy

and

animateRotateBy

, but one runs, then the other after the first has finished. So the object pans across, then rotates. I'd like the object to pan while it is rotating. Is this possible somehow? Thanks! Goodnight all.

anyone aware of anyone doing the “make a rogue-like challenge” with compose-desktop / -mpp yet?

Hi, is there still no way of adding global hotkeys?

How to achieve window blur like shown in the image?
