kotlinlang #compose-desktop

Thought I'd drop an idea for our technical writers here. It would be great to have some sort of guide, example or just a simple PoC of distributing CfD app via flatpak.

How are people sharing resources between an android app and desktop app using the multiplatform stuff? Is everyone else doing a thing where they have an expected object that has a list of

@Composable

functions that return

Painter

instances?

How can I build an Intel version of my mac os app? I tried including

implementation(compose.desktop.macos_x64)

in my dependencies, but when i do

./gradlew runReleaseDistributable

on my M1, the app crashes with “Failed to launch JVM”

If you don't need the MAS then Conveyor can do this. It cross-builds for every target from your laptop. Unfortunately, we don't currently support making uploads to the app store. It's on the todo list, but unless you want the integrated billing or discovery out-of-store distribution seems to work just as well (Conveyor makes a download page for you, provides sparkle updates and other things you'd need).

I've noticed that my compose app has the light title bar when windows is using dark mode and everyapp has the dark title bar. Has someone faced the same issue? I've only found comments about macOS but nothing about windows

I've been working with persistent data structures for my font editor, which has been interesting. I have an object model like in the image. I am tracking the selected points with a PersistentSet - however, this makes it hard to update the selection: when I move the points for example, it creates new instances and so I need to update the selection set to remove the old and add the new ones, which is cumbersome. Does anyone have an idea how to track selection for immutable classes more easily?

I am in a

jvm

module, and I want to have access to some compose classes. I get a problem, where I get an error which among other things says

AmbiguousConfigurationSelectionException: Cannot choose between the following variants of org.jetbrains.skiko:skiko androidRuntimeElements-published awtRuntimeElements-published

Looks a lot like this issue but isn’t quite the same. Anyone experienced this before? Not sure if it’s the right channel but thought I’d give it a try.

@Aman Kapoor did you figure this out?

Alex Styl

is there any way to check if the app is development during runtime (like Android’s BuildConfig.DEBUG)? I am currently using the build config plugin and have a IS_DEBUG boolean which returns if gradle is not running on CI. Wondering if there’s anything out of the box i should know of

Did Bugsnag work out of the box for you? When I run a release build with proguard on, then the errors are not sent to the dashboard. proguard was also failing without adding Jackson specific proguard rules. that’s weird cause i havent seen that mentioned in the documentation or here

where are proguard mapping files stored in a jetpack compose desktop app? can’t find a ‘mapping.txt’ file anywhere

Alex Styl

I am trying to sign my mac os app (

.app

created by

./createDistributable

& share it outside of the app store). I am following the Signing and notarizing distributions for macOS tutorial and I am getting

Unnotarized Developer ID

when I check if the app is signed (using

spctl -vvv --assess --type exec /path/to/*.app

). Can’t find online what that error message means

Alex Styl

Updates on the notarization process (https://kotlinlang.slack.com/archives/C01D6HTPATV/p1667796592609049) Notarizing the app takes time. When you create a distributable with a valid developer ID, it starts a notarization process. You will get an email when the process is done. only there you can check with the above terminal command if the app is safe or not. this took way too long to figure out

mikehearn

11/07/2022, 11:28 AM

Yes, notarization can be annoying. Remember to staple the ticket to the app! Conveyor does the upload and then polls Apple's servers until the ticket is available, so once the build process completes you know you have a fully notarized app. They seem to have sped it up recently. It used to take several minutes for notarization to complete, now it's more like one minute or a bit less.

Alex Styl

11/08/2022, 5:01 AM

Is there a task to notarize an app? In the notarization tutorial the

createDistributable

is mentioned which creates an

.app

file, but i only see notarize gradle tasks for pkg and dmgs

Is it possible to have access to platform specific APIs? What I am trying to achieve is display and hide Mac OS notifications from my jvm app. I am away of Tray notifications but that is limited as I cannot hide notifications. To my understanding there are no kotlin or jetpack compose desktop APIs for that and I would need to figure out my way through the JNI. is that right?

can you opt-out of notifications on macOS when the app is packaged as

.dmg

? I didn’t do anything to include notifications, but when I run the app there is a notification shown (reposted to add screenshot)

Hello! When updated to version 1.3.0-alpha01-dev849 got some strange behaviour of androidx.compose.material3.ModalNavigationDrawer. It's drawerContent become not fully hidden. And when resizing window larger in width then drawerContent takes all extra width (in hidden state). How to make it hidden fully? Usage example:

ModalNavigationDrawer(
        drawerContent = {
            Column {
                repeat(10) {
                    NavigationDrawerItem(label = { Text("Menu item $it") }, selected = false, onClick = {})
                }
            }
        }
    )

Hi, I need to implement a custom focus managing logic, and I intend to store some

FocusRequester

in my state object and use them to focus on the views. I tried this approach on a sample app and it works, but is it advisable to do that? Is that a bad practice? Thank you

Hi all, I am trying to load image from url and randomly encounter the error as below

Failed to Image::makeFromEncoded

Abdelilah El Aissaoui

I've got a lazy column of text lines wrapped with a SelectionContainer. It works quite nicely as long as I don't scroll, if I scroll, the selection simply stops randomly, like if I released the mouse click. I think there was an issue related to this but I haven't been able to find it, I'll create one otherwise. Sample to reproduce it:

SelectionContainer {
        LazyColumn {
            items(100) {
                Text("Line number $it")
            }
        }
    }

I've also noticed some items can be skipped like in the attached image. Text selection in lazy columns is quite buggy in general, not sure if I can do something to improve it. CodeViewer demo has the same issue.

SelectionContainer {
        LazyColumn {
            items(100) {
                Text("Line number $it")
            }
        }
    }

Playing around this issue a bit more, I've found that it happens whenever the first items selected is scrolled out (so no longer visible). Yikes

The issue seems to be present also in Android

this feels like a compose issue than desktop specific. i would have mentioned in in #compose or open an issue if i were you
