Anyone has tried to target the Raspberry Pi with their Compose Desktop app? I haven't seen any mention of it here yet. I'm working on a pet project on the Raspberry Pi, and, if feasable, I would like to try out Compose Desktop at the same time. I have found TotalCross (https://github.com/TotalCross/totalcross) which seems to be another interesting option, but Kotlin doesn't seem to be a first class citizen... Thanks!

Not sure if this is just some outdated docs, but in the code, shouldn't the

by remember

changed

= remember

? And to then add on that, in the places where they are used, to use the

value

property on them? https://github.com/JetBrains/compose-jb/tree/master/tutorials/Keyboard#focus-related-events

Hey everyone. Trying to compile some code on windows (after it successfully did the Jar on Arch Linux, however not the Deb package..). I'm getting an interesting error. Is this perhaps because I am using JDK 15?

Execution failed for task ':packageMsi'.
> Process 'command 'C:\Users\hamza\.jdks\openjdk-15.0.1\bin\jpackage.exe'' finished with non-zero exit value 1

The stacktrace is just a ton of internal calls. let me know if you need it 😛

How can I enforce fullscreen on startup?

Hi everyone. On Windows the "About" menu item usually has no shortcut. However, Compose for Desktop currently uses KeyStroke(Key.Unknown) as a default (if I do not pass one in), so I end with this. Am I missing something, or should I open an issue?

Hey folks, Might be a silly question so excuse me if I’m a bit too new to this, but where can I find the option to create an installer? Ive gone through this tutorial: https://github.com/JetBrains/compose-jb/tree/master/tutorials/Native_distributions_and_local_execution Unfortunately I cannot say I fully understand the matter and how to trigger building an installer. Any help would be greatly appreciated and sorry for the bother 🙂

Is there a way to make IntelliJ to stop complaining about Pascal Case method names when it's annotate with

@Composable

?

Cause I already created some things for my project and wonder if there is some project where we can share things

Btw. little status of work on my Crusader Kings 3 Modding Tool with Compose for Desktop. I am getting warmer and warmer with the concepts ✔️ Looking for helping hands so if your a CK3 fan and ... well in this slack channel then peek here: https://github.com/xetra11/CK3-Workbench

Is there a way to take the compose window and render it to an image file instead of displaying on screen?

@Kirill Grouchnikov from what dependency repo can I install it?

Is there already a way to check in

onClick

events if a modifier has been press or for example a "right click" happened?

TL;DR Ultimately we might need the ability to have the client app specify a look and feel Currently writing an article called Musings on window decorations, as I am still on my mission to get complete Dark Mode into my Compose for Desktop app. 😂 To sort of whet your appetite please look at the short clip. Yes, it's the Swing Cross Platform look and feel, because we need the ability to have Swing paint the window decorations and neither the Windows Look and Feel nor the macOS Look and feel Swing implementations allow this. I will be detailing more regarding code and maybe a thing we JB might need to change in Compose. To start with, just a few lines of code: In `main()`:

invokeLater {
    JFrame.setDefaultLookAndFeelDecorated(true)

and later in a composable:

val window = AppManager.windows.first().window
getDefaults()["activeCaption"] =
        ColorUIResource(colors.background.toArgb())
getDefaults()["activeCaptionText"] =
        ColorUIResource(colors.primary.toArgb())
window.rootPane.windowDecorationStyle = JRootPane.FRAME
UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName())
SwingUtilities.updateComponentTreeUI(window.rootPane)

Please note that I need to set the look and feel, because deep inside Compose (

org.jetbrains.skiko.Library

) it apparently (decompiled code) is initialized as:

private final void miscSystemInit() {
   System.setProperty("sun.awt.noerasebackground", "true");
   System.setProperty("skija.staticLoad", "false");

   try {
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
      System.setProperty("apple.laf.useScreenMenuBar", "true");
   } catch (UnsupportedOperationException var2) {
   }

}

The best thing would be to have a Swing Look and Feel that fits the Material Design look alike, at least for window decoration and menubars inside a window. And we might need the ability to have the client app specify a look and feel and pass it there...

Hello, I'm what's the recommended method to navigate/route views in desktop? I've tried to import

androidx.navigation:navigation-compose

but getting aar gradle import issues. I've been told this is not available for desktop yet. All I want to do is have sidebar items and be able to change the view on the main right panel. Most of the examples are using some sort of state but for the same view only such as Issues or Code. Also If I have an

onClick

method it tells me this can't return a composable as I've tried to do it that way, passing in a composable or returning a composable upon clicking

What is the recommended way of drawing text inside a

Canvas

composable since there is no

drawText

method. I have a requirement where I rotate the canvas and draw some lines with some text. I'm currently using

drawContext.canvas.nativeCanvas.drawText

hello getting my feet wet with compose for desktop how do you subscribe to changes in

MutableState

? (i’ve close to zero experience in android)

the idea is when

path

is updated the

files

list will reflect the change

can you use the @Preview annotation in compose desktop?

just so i understand i see people from G around this subject does it mean that google is involved in jetpack compose? as opposed to jetbrains?

Completely new to desktop development (in addition to compose, but im a long time android dev) I'm trying to just build a button where onClick it posts a notification to my mac. Is that something that's supported through compose desktop apps, or do I have to look for some kind of swing library that knows how to do this? (never used swing either). I'm assuming that this might not be possible because notifications are handled by the OS and there doesn't seem to be some kind of java <> macOS interop library (unless my google skills are failing me?)

I tried some first steps with compose and i like it 🙂 However - is there some tool or library that would provide a navigation stack (for desktop)? The ones I found use androidx and dont seem to work inside the desktop universe

Just read about the AppManager singleton here: https://github.com/JetBrains/compose-jb/tree/master/tutorials/Window_API#appmanager It gives an example of using

AppManager.setEvents(
    onAppStart = { println("onAppStart") }, // Invoked before the first window is created
    onAppExit = { println("onAppExit") } // Invoked after all windows are closed
)

It doesn't tell you where you would call that though? Since it's invoked BEFORE window is created... I wouldn't put it in my window right? But where do I put it? As a top level function? I'm probably missing something basic here.

Again, apologies for the noob question, but changing my title doesn't seem to change it on the OS level. I want my app to be called "Yay". Same with my notification, except it says "Java". I guess I'm missing some larger configuration somewhere. I did look in tutorials and the only title changes it had were in the Window tutorial.

Looking for advice on form state management with domain

data class

objects updated by the inputs. To use or not to use? Details will be in the thread.

Hi everyone. There might be an issue regarding responsiveness... Before I open an issue on GitHub, would someone please kindly verify if this is reproducable? Running a short demo on Ubuntu 20.04 causes a Compose for Desktop app to become unresponsive if the theme is switched while the app is running. So, on Ubuntu 20.04 • run this app (button presses print hello • While the app is running, open Settings and change the scheme to/from dark mode • now button clicks no longer print something

I just learned about compose (desktop) and am now wondering if it is somehow possible to do some 3d rendering inside the application?

What does this line in gradle actually do?

implementation(compose.desktop.currentOs)

Whenever I add this line it breaks all usages of reflect(), when it's reflecting a suspend function

What is this module there for: https://github.com/xetra11/compose-jb/tree/master/components Is it for people to share components or will these components be introduced to the next CfD releases?

Hello, I'm new to compose with a lot of (stupid) questions (after trying JavaFX + ControlsFX + Gradle + Kotlin on IDEA Ultimate and almost killed myself with the build processes). But first, at the moment what is the right way to create UIs? Use Android Studio to benefit from the @preview annotation then switch to IDEA when it looks ok while keeping in mind that some components are not ported yet (like RangeSlider)? (I fully understand the early stage of all those things).
