kotlinlang #compose-desktop

Has anyone written a window-in-window layout manager for compose? I'm porting an app from JFace/SWT and I'm missing the ability to have tabbed panels that can be dragged/resized. SplitPane gets part of the way there.

I have just tried to update an example multiplatform project to 1.2.0-alpha01-dev741 and Kotlin 1.7.10 (1.7.0 is the same) from dev-731 and get the following error message when I build for iOS

java.lang.IllegalStateException: IrBasedSimpleFunctionDescriptor: FUN name:DataTooltipArea visibility:public modality:FINAL <> (dataString:kotlin.String, modifier:androidx.compose.ui.Modifier, content:kotlin.Function2<androidx.compose.runtime.Composer, kotlin.Int, kotlin.Unit>) returnType:kotlin.Unit [expect]

The project builds and runs perfectly on JVM and even on Web (Canvas). Can anybody tell me what this error message actually means?

I would like to use fonts from AWT in Compose. Is this possible? My goal is to allow users to select between some fonts. Are downloadable fonts supported in Compose for Desktop?

Is it possible to use LWJGL 3 AWT within Compose? My current attempt results in

No context is current or a function that is not available in the current context was called. The JVM will abort execution.

I'm sure this is due to some threading done underneath and was wondering if there was a way around it. I'll post code in thread. I'm not tied to using LWJGL or AWT, I simply wish to utilize OpenGL within Compose 🙂

Is there any update on the simplified proguard integration? I just added the extended material icons for one or two of them. I don't really care that much about the resulting package size. It looks like 28 MB for those icons.

Both latest versions

v1.2.0-alpha01-dev741

and

v1.2.0-alpha01-dev745

compile just fine with Kotlin 1.7.10. Did anything change recently? I thought we would have to wait for a release compatible with Kotlin 1.7.10.

How would I make it so that I have a box that responds to pointer inputs (custom dragging), but then inside of that box there is a smaller box which should not respond to dragging anymore? I'm unsure of how to stop the pointer input from cascading down to child elements. I'd like a box to be draggable but not allow the custom buttons inside it to be draggable.

Hi, today I tried to run "packageMsi" gradle task on my compose-desktop project but I got this error:

Cannot expand ZIP 'C:\Users\User\Documents\project_dir\build\wixToolset\wix311.zip' as it is not a file.

In fact "wix311.zip" is not a file, but a directory that contains a "wix311-binaries.zip" file. I checked online but I haven't found any reference to this bug. Do you have any idea if it is a known issue and how may I resolve it? Let me know if there's any information I can provide, thanks. This is the gradle output just before the mentioned error message is printed:

18:35:25: Executing 'packageMsi'...

I wonder if there is a checklist somewhere for a reusable desktop component to check against. Like, accessibility, focus, RTL, etc. If anyone has their own, can you share it maybe?

I’ve google sign in working on Android, iOS and Web, and I was wondering, how can i use it too in a compose desktop app? 🤔 Do i need a “webview” and then intercept an “OK response”, close it and proceed with “app logic”? Anyone tried it? Thanks! 🙌

We’re using compose desktop within an Intellij IDE Plugin. It was working great up until recently but it seems like with Intelij 2022.1 (Android Studio Electric Eel build specifically) it just stopped working. Initial drawing works, but then recomposition just doesn’t seem to happen. Click and key press callbacks happen, but updating State doesn’t trigger recomposition, and things like mouse over highlights for standard components don’t show. It’s really bizarre, and I don’t see any errors in logs to point out what is going on. Debugging doesn’t give me any hints either. Anyone in a similar position?

In you documentation about deeplinks you have a sample showing how to do it in macOS. Tested and works perfectly, but how about

Hi all! In the Swing Interoperability examples (https://github.com/JetBrains/compose-jb/tree/master/tutorials/Window_API_new#swing-interoperability), it is shown how to open an AWT file dialog. I see that there is a

window

in the

FrameWindowScope

of the

Window

composable, but is there a corresponding ambient?

Code Review:

fun onRefreshTrackCollection() {

        refreshTrackCollection()
    }
    when(job.isCompleted) {
        // show snackbar message

How do I better execute a UI change when a coroutine job is complete?

Hey Eveybody, is there a way to prevent the default behaviour of key events on an BasicTextField? Im currently reacting to a KeyDown Event on

Key.Enter

by using the

onPreviewKeyEvent

Modifier and I do not want the

BasicTextField

to unfocus when Enter is pressed. I was searching for a solution like preventDefault in JS but couldn't find anything so far.

Hello! I’m trying

1.2.0-alpha01-dev741

and I’m having problems importing androidx.compose.foundation.lazy.grid. With version 1.0.1 I was using*:*

import androidx.compose.foundation.lazy.GridCells
import androidx.compose.foundation.lazy.LazyVerticalGrid

Now, with version 1.2.0-alpha01-dev741 I have to change to:

import androidx.compose.foundation.lazy.grid.LazyVerticalGrid
import androidx.compose.foundation.lazy.grid.GridCells

Otherwise the IDE throws an error. Up on changing the IDE doesn’t complain and finds the classes, but when I try to build I get the following:

> Task :shared-ui-compose:compileDebugKotlinAndroid FAILED
Unresolved reference: grid
Unresolved reference: grid

Upgrading to

1.2.0-alpha01-dev748

is failing with

This version (1.2.0) of the Compose Compiler requires Kotlin version 1.7.0 but you appear to be using Kotlin version 1.7.10 which is not known to be compatible.  Please fix your configuration (or `suppressKotlinVersionCompatibilityCheck` but don't say I didn't warn you!).

Meanwhile

1.2.0-alpha01-dev745

is working correctly 🤔

, and it seems doing it via

is the best way of doing so.

Is it possible to animate Window/WindowState size? I’ve tried the following (code in thread):

fun main() = application {
    var expand by remember { mutableStateOf(false) }
    val width: Dp by animateDpAsState(
        targetValue = if (expand) 1024.dp else 600.dp,
        animationSpec = tween(durationMillis = 250, easing = FastOutSlowInEasing),
    )
    val height: Dp by animateDpAsState(
        targetValue = if (expand) 1024.dp else 600.dp,
        animationSpec = tween(durationMillis = 250, easing = FastOutSlowInEasing),
    )
    val dpSize: DpSize by remember { mutableStateOf(DpSize(width, height)) }
    val windowState = rememberWindowState(size = dpSize)

    Window(state = windowState) {
            MyComposable(
                onSomething = {
                    expand = !expand
                    //windowState.size = dpSize
                })
    }
}

To make it work I’ve to change the size here:

//windowState.size = dpSize

directly, but this will not animate 🤔

I’m lost, any hint?

Sean Proctor

07/24/2022, 8:08 PM

Did you figure this out? I think you want to do the

windowState.size = dpSize

immediately after

val windowState = ...

It might be better to update the size in a launched effect:

LaunchedEffect(dpSize) {
    windowState.size = dpSize
}

Guilherme Delgado

07/25/2022, 9:12 AM

I did not 😞 and the

onSomething

- in this case - it’s actually being called inside a

LaunchedEffect

, but the key is not the dpSize 🤔 will try to add it as key to see what happens (edit: nothing 😢).

I think the animations for some reason are not running/changing the window state. The same code animates a “normal” composable 🤷

LaunchedEffect(animate) {
    repeat(5) {
        delay(1000)
        windowState.size = DpSize(windowState.size.width + 100.dp, windowState.size.height)
    }
}

quick test and this is the only way I can “animate” the

windowState.size

🤮

@Sean Proctor maybe this is why:

/**
 * Creates a [WindowState] that is remembered across compositions.
 *
 * Changes to the provided initial values will **not** result in the state being recreated or
 * changed in any way if it has already been created.
 *
 * @param placement the initial value for [WindowState.placement]
 * @param isMinimized the initial value for [WindowState.isMinimized]
 * @param position the initial value for [WindowState.position]
 * @param size the initial value for [WindowState.size]
 */

🤔

Sean Proctor

07/27/2022, 11:28 PM

That makes sense. The window isn't a normal composable, so state hoisting won't work. I'm not very fluent with the animation APIs, so maybe there's something that looks a bit more elegant than what you have, but what you have is pretty close to what I was thinking. How does the animation itself look with that code? Maybe if you decrease the delay to something like 20ms or so it would look nicer?

Guilherme Delgado

07/28/2022, 9:26 AM

It doesn’t feel smooth and pretty like animation API, specially because I was thinking about using spring() or something non linear, but well, it does the job considering all constraints.
