kotlinlang #compose-desktop

Hi, I would like to know: If I have a KMP project (for now, only Android and Desktop targets) and with shared compose components, there is any way to write composable tests in the common source set or I need to choose between Android and Desktop?

Holy crap. I think CfD finally works correctly for me in Android Studio. All of my red lines seem to be gone. The trick (seemingly) was to delete the .idea/modules.xml file and then clean > rebuild. 😛arty-parrot:

There are a couple of threads about it but no clear answer: does

rememberSaveable

do anything on desktop currently?

Hi, I'm trying to find a way to bundle assets (aapt, adb, android.jar, etc.) with the dmg and exe files, is there an easy way to do this?

Can I share this code between Android + Desktop somehow?

private val Rubik =
    FontFamily(
        Font(R.font.rubik_regular, FontWeight.Normal),
        Font(R.font.rubik_bold, FontWeight.Bold),
        Font(R.font.rubik_medium, FontWeight.Medium))

or do I have to do some sort of expect/actual thing here?

How to add opt-in annotation to

build.gradle.kts

? In Android I can use

android.kotlinOptions.freeCompilerArgs += "..."

, in KMM -

kotlin.sourceSets.all.languageSettings.optIn("...")

, but how to do it in compose-desktop?

Hi i am trying to run compose app on raspberry pi 3. I have simple app with button and counter and it is for some reason laggy (The button ripples). Is compose really that performance heavy that raspberry pi 3 could not handle it ? If i create similar UI in javaFX it runs smooth. Does anyone know if there is something that I could be doing wrong or compose is just not suitable for raspberry pi 3 ?

doesn anyone know why the ripple is not gray?

🤔 What’s actually happening inside

::exitApplication

System.exit(0)

or something special? Just curious 😬

Following the guide here

System.getProperty("compose.application.resources.dir")

returns

.../app/build/compose/tmp/main/resources

which doesn't exist. What am I doing wrong?

How can I execute a left mouse click on a

ComposeScene

? I already tried

scene.sendPointerEvent(PointerEventType.Press, offset)

but either I am doing something wrong (maybe with the

Offset

?) or more is required to achieve this. (Regarding the offset, I already tried pixel coordinates and a scale from

0f

1f

ComposeScene

has the

hasInvalidations

function, which I currently check periodically. Is there a way to setup a callback which will be executed if this value changes to true?

I'm trying to implement editable Text myself, and I'm stuck right at the beginning - how to show the cursor when the user clicks somewhere in the text? ClickableText gives me the index of the clicked character, but that's not enough to show the cursor - I need the pixel position and the height of the cursor to display. Any pointers appreciated...

How can I capture key events happening on a

ClickableText

? I've tried with

Modifier.onPreviewKeyEvent

but nothing seems to be happening...

so em.. this question might be too early, but is it safe to assume that material3.compose apis won’t make it’s way to compose multiplatform soon?

Hi. Is there a way to make the Gradle plugin produce just a set of JARs - not an uber jar or a jlinked package, but what you'd get in the lib directory if using

installDist

on a normal Gradle application module.

@Igor Demin - I think the code in https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]kotlin/androidx/compose/foundation/Scrollbar.desktop.kt;l=222 (desktop scrollbar) needs something along these lines to support RTL mode (see code in thread)

https://github.com/JetBrains/compose-jb/tree/master/tutorials/Mouse_Events#mouse-rightmiddle-clicks-and-keyboard-modifiers has been reworked recently from

Modifier.pointerInput

Modifier.mouseClickable

. At the very end it says

If you need more information about events there is an available raw AWT mouse event object in mouseEvent property of PointerEvent

but it's not clear where is that

PointerEvent

. More specifically, what is the equivalent of

MouseEvent.isPopupTrigger

- which is pressed on mac, but released on windows?

I'm going back into my old projects and trying to add @Preview since I was able to get it to work now in plain old Android Compose projects. But now I have a jetbrains compose project, and I have an

androidMain

folder that I'd like to be able to use @Preview. Then in my commoncomposables module build.gradle.kts I have

named("androidMain") {
  dependencies {
    implementation("androidx.compose.ui:ui-tooling-preview:1.1.0-beta01")
    implementation("androidx.compose.ui:ui-tooling:1.1.0-beta01")

But as you can see, the IDE doesn't give me the code/design/split pane. Does anyone know if I should be able to see that pane so I can have previews without deploying to device? Note: I don't care about previewing my desktop composables or anything, I just want my androidMain folder to be able to preview as you would in a normal android compose app.

The obvious hack would be to just +x it from inside your app code

Congrats with beta release! I'm curious: the blog post said,that compose-desktop now uses google artifacts directly, but I've updated my playground-project to

1.0.0-beta05

and if I go to e.g.

MaterialTheme.kt

I can still see that IDE locates it in

material-desktop.jar

. I did resync and clean build project, this is still a thing. Is this supposed to be so?

are there any open source Compose Desktop apps in the wild right now? Preferably not demos, but apps intended to be used

Besides the jetpack for android tutorials, can anyone recommend any good tutorial for compose desktop?

I'm having couple issues with transparency support on Linux, • At my second monitor (4k one) it fails to setup SkiaLayer with a exception (in thread). • When It get open at my primary monitor (2k) it have a poor performance, when I switch my second monitor to 2k the peformance get alot better. (the application is still being displayed at the first monitor) • When I try to move the window to the second monitor (SUPER + SHIFT + LEFT) it gives my the exception in the first case and stop working.
