Hello, perhaps this is too broad of a question, but, is there any good book that goes through the principles of writing desktop apps? Coming from years of working on distributed backend systems (think spring, webapps) I find myself very lost on how to structure a desktop app (or what does a desktop app really need).

While working with a

LazyColumn

with a

VerticalScrollBar

, i’m using

rememberScrollbarAdapter

as the adapter and it requires

averageItemSize

. I could imagine this works fine when the items are expected to be the same size. How do i handle the case when items might not be the same size. Is there an alternative i might have missed?

Are there any plans to provide a platform specific look and feel? E.g. a Windows theme, an integration with the GTK theming system... in order to have a more integrated looking app

Hi, I'm building my desktop app to an MSI but when I run the .exe, nothing happens (the executable just exits immediately). I suspect there are some dependencies missing from the installed files. My app uses

javafx

and my build.gradle.kts has these dependencies in it. If I rip out the

javafx

dependencies and associated code, the app installs and runs fine. 1) How can I package up my app to run with javafx?, and 2) is there a way to diagnose the running of the .exe issue (e.g. any diagnostics or logs to view)? build.gradle.kts excerpts:

plugins {
    kotlin("jvm") version "1.4.30"
    id("org.jetbrains.compose") version "0.3.0"
    id("org.openjfx.javafxplugin") version "0.0.9"
}
...
javafx {
    modules("javafx.controls", "javafx.swing", "javafx.media")
}

Thanks!

Hi, does anyone know of a way to debug or log to console a packaged Mac app made with Compose Desktop? When I run the runDistributable task my app works as intended, but when I run packageDmg and use the resulting app it seems that there is an issue with the SQL database, ViewModel or something related to data persistence.

Just for learnability, I was migrating a reaaaaaaaally old toy project/game I did few years ago. I tend to replace the AWT UI by Compose. It's a really simple game, no big deal here. The impl of the logic layer was using Java `Observer`/`Observable`, I try to keep it as is for now (keeping compatibility with old Java/AWT UI layer). How may I recompose what needs to be based on such impl?

what is the best way to make a Rect clickable in canvas?

does any one successfully generates native image of jetpack compose desktop app with graalvm?

Does anyone have recommendations for how to protect a Kotlin desktop application from being reverse engineered? Proguard is an obvious step. What else?

I have a multiplatform project with two JVM source sets: a Ktor server and a Compose frontend. When I compile the server, I get

You are using an outdated version of Compose Runtime

errors from compose, I assume because the plugin it applying itself to all modules. Is there a way to disable compose for some modules? I don't have access to

buildFeatures

afaik since I'm not using android.

High-level question: I'm trying out

compose-desktop

in a side project of mine (so I'm really new to this tool), and I'd like to be able to integrate it with a 3rd party rendered component (specifically

lets-plot

). I see that the component specifies that it can be rendered with JavaFX and Apache Batik but I'm not seeing a way to be able to render the component using the compose desktop API. I was assuming there would be some sort of panel I could use to be able to position the graph, and then let the component handle the rendering, but perhaps I'm wrong. Does anyone here have any ideas of what I am missing, or is this even possible?

Hi folks, I have a Low level idea here: I want to do a Server Side rendering of Compose Desktop app using Skiko Software render, the idea is to send the Skia Canvas output through the network, this could be doable? Any one can give me some ideas in how can I accomplish this?

Question about

androidx.compose.ui.input.mouse.MouseScrollEvent

and

MouseScrollUnit

: I am using a

mouseScrollFilter

and am wanting to perform some mathematical operations using the

delta

(for zoom on scroll), but I can't seem to figure out how to get the actual value from the

delta

, there's no accessors or anything for the raw Float value. I understand there's the line/page scroll values but those don't seem accessible either, so not sure if I'm just thinking about this incorrectly.

Is anyone signing and notarizing their compose desktop macOS app? There seems to be a regression after upgrading from compose 0.3.1 and Kotlin 1.4.30 to compose 0.4.0-build182 and Kotlin 1.4.32 It compiles, signs, and uploads, but notarization is rejected by Apple a few minutes later. When I dig into the server logs from Apple, the error message is

"statusSummary": "Archive contains critical validation errors",

and

"message": "The signature of the binary is invalid.",

If I roll back to compose 0.3.1 and Kotlin 1.4.30, then the signing issue goes away again. Is signing broken with the newer version, or did something change with how we’re supposed to configure the gradle build DSL for signing?

Some kind of hot reload is now available :-D https://gitlab.com/compose1/livecomposable Please keep in mind that this is still under heavy development. Also it needs some input from you how we could improve this.

Does Compose Desktop require JDK 15 now? Or it should work on 11? I've just downloaded newest IntelliJ CE and created an empty compose project using intellij wizard and it doesn't run. I'm getting some class loading errors. I have jdk 11 configured on my system but maybe something has changed and now compose requires newer version?

Apologies - can anyone explain what I need to do to fix this message:

Functions which invoke @Composable functions must be marked with the @Composable annotation

- I can't mark

main

as composable; I tried moving the body of my application into a separate @Composable function, but I feel like I'm missing some key understanding here.

Maybe I missed something completly obvious but I tried to create an lazy list from the return of a flow but the State dosn't get updated Code in the 🧵 [SOLVED]

I seem to remember seeing a tutorial or sample or something once for writing an IntelliJ plugin’s UI with Compose. I can’t figure out the right things to google apparently – does anyone know where to find this? Or did I just imagine it?

Didn't see this here and thought it was cool https://github.com/supertechninja/Jetpack-Compose-Theme-Configurator

Has JB wrapped Skia in some inaccessible way? I'm trying to convert a Skia Bitmap (for a Canvas) to black and white; all my searching returns methods like `

Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

But there is no createBitmap function available. Nor pretty much any of the Android Bitmap functions.

There is no suggestModules gradle task in the default jetpack compose project created from Project Wizard. What am I missing?

Guys are there a way to include firebase features such as remote config, analytics, and crashlytics into a jetpackCompose desktop ? or any alternatives?

Having fun with the new WSLg. Running compose desktop on linux on windows 🙂

I've been using compose-desktop for 3 months in some of my pet projects. here's my experience so far 👍 Framework Stability : 🟢🟢🟢🟢⚪ 🤗 Community Support : 🟢🟢🟢🟢🟢 🔀 Cross-platform Stability : 🟢🟢🟢🟢⚪ ⛓️ App Size : 🟢🟢🟢⚪⚪ 🚀 DX (Developer Experience 😛 ) : 🟢🟢🟢🟢🟢

Is there a way to retrieve a composable's bounds relative to application's window?

Is there a way to draw centered text on canvas? I can find solution in Android compose. but on the desktop, the

Paint

class is different

is there support for tabbing through a form? i'm looking through

androidx.compose.ui.focus

, but the documentation is a little sparse.

Is it possible to work on compose desktop through Android Studio? I'm trying to setup a hello world app but running into several issues like this one . I think I should specify the correct JDK but Android Studio does not seem to have the handy JDK version dropdown in Project Structure.

Native Distribution Error: I've used the packageExe Gradle Task to create a distribution for a Windows system it installs perfectly but when executed is throws the attached exception. The build file will be in the Thread 🧵 [SOLVED]
