Playing with animatable render effects. Demo code starts here.

Is it possible to have the CfD installer associate a custom URI protocol with the app? I'm trying to implement an oauth/oidc flow and that seems to be the most appropriate way to get the response from the browser.

What do you use for crash reports, is there a Crashlytics equivalent?

Is there any way that we can customize the WixToolset configuration when packaging an application. I would like to write some registry keys to support custom URIs for a Windows Application.

Hey everyone! So I'm making a game for classes, I'm currently in a pretty advanced state, the last thing I'm lacking is a simple UI, as my whole project is in Kotlin, I thought that going with Compose was the best way to go... As I don't want to spend too much time on the UI (I want a simple grid to display my map and a sort of move-logger on the side), I tried to go with the following thing :

@Composable
fun TileMatrixViewer(matrix: TileMatrix) {
    Text(Helper.displayer.showMap(matrix), fontFamily = FontFamily.Monospace)
}

object Helper {
    val displayer by lazy { BaseDisplayer() }
    /* some other things */
}

But the

Text

widget never updates when I change the position of a player, how can I make it so it is updated? You can see the whole class for

TileMatrix

right here on my git if it might help to answer -> https://github.com/HFDrae/RoguEngine/blob/main/src/main/kotlin/util/graph/tiles/TileMatrix.kt Another question that might make this one useless, how should I go if I want to display my grid as a grid of components rather than a String that represents the whole grid ? Thanks in advance !

Hi everyone! I’m a JetpackCompose beginner, I’m customing the TextField to center for content in TextField. But the cursor does not center when beginning focus. After inputting the value was center-aligned. How I can fix the cursor center when begin to focus the TextField? Thanks!!!!

Is it somehow possible to visualize (or debug) recompositions?

Closing the functionality gap with Android T / Compose on Android for shader-backed render effects that can run on any node in Compose hierarchy. This Skiko issue has a bit more technical detail. Once the PR linked in it is merged, and Compose Desktop picks up that version of Skiko, it will be made available for all supported desktop platforms. This demo is a simpler one, applying a static shader render effect. This demo is a bit more complex (see attached video). It shows a dynamic shader that "combines" two child shaders, one that blurs the left part of the button, and another that colorizes the right part of the button to be red-tinted. The slider under the button is wired to change the horizontal boundary between the two child shaders, showing how to combine

remember { mutableStateOf }

together with the newly added binding to the underlying

SkRuntimeShaderBuilder::uniform

. When the mouse is moved over the button, the amount of blur and red tinting goes down, showing how to combine

derivedStateOf

with the same

SkRuntimeShaderBuilder::uniform

. Apart from the more demo-ey nature of this video, this should enable not only the things done in Android (stretch overscroll, content blur, fancy ripples), but also things like image editing with quick live previews of effects, introduction tutorials that blur / highlight relevant parts of the UI, and many more.

Sorry if this is a stupid question, but when I ran a desktop application on mac, there is always this

MainKt

reference as the process name. Can this be adjusted by an application name?

I guess this is OS specific, but I know that at least on macOS there are apps which change this titlebar colour (ie. IntelliJ does it, iTerm does it, etc) is there a way to do this with my CfD app? I’ve tried switching between dark/light theme and that doesn’t seem to have any effect on the title bar EDIT: ☝️ figured it out, see 🧵 if you’re interested 😄

Can we use compose-jb for an android-only project without the multiplatform plugin?

The OpenGL renderer supports more/older computers. What is the argument for not making OpenGL the default renderer for my CfD application, rather than DirectX 12?

@Kebbin extending from here :thread-please:

How onerous is it to actually create a CfD program for macOS?

Is it possible to get light and dark variants for a

Color

?

Along the same vein of Android's shimmer ripple, here's a more realistic example of a "decorator" shader-based runtime effect applied on a button. The button on the left is a regular Aurora button, and the one on the right is configured with a render effect that uses a shader to draw an outside glow when the mouse moves over that button. No need to increase the layout bounds of the button. No need for the button composable itself to be "aware" of this glow drawn around it. The render effect layer handles all of that, and all you need to do is pass all the relevant info (in this case corner radius, glow amount, max glow distance and glow color) into the shader. And of course, write the shader itself 😅

I try to use outlined icons, but they are always filled. Does anyone know what am I doing wrong?

Icon(
    imageVector = Icons.Outlined.Star,
    contentDescription = "contentDescription",
)

Why does an empty desktop compose app (just showing an empty window) take 100MB in memory (Mac OS X)? Is there anything I can do to reduce this? An empty regular Kotlin app takes 30MB, for comparison.

Hello, are PRs allowed for this repository? I want to make the

ViewModel

and some of the navigation componenet multiplatform.

I’m setting up my project, including both desktop and android, to run in multiple environments, but the error below occurred. How can I run my project in different environments?

org.gradle.api.InvalidUserCodeException: Only one of the JVM targets can be configured to work with Java. The target 'common' is already set up to work with Java; cannot setup another target 'dev'

Just for the sake of being the first one to ask: when will there be a version of CfD for the freshly released Kotlin 1.6.20?

Any good examplse about how to implement internationalization on desktop, guys?

Hi all, i'm trying to render 16x16 px tiles on a compose Canvas. Im unsure about how do do this in a relatively sane manner (i know that probably anything i try will be "good enough"), my thoughts are to create ImageBitmaps for each tile on start (complicated by the fact that the tiles are saved onto a single png, im assuming i can slice an ImageBitmap of the sprite sheet) and draw them individually onto the Canvas, but do thoughts jump out to anyone?

Is it possible to hide the cursor of

OutlinedTextField

? I would like to use it as an uneditable value holder for a dropdown list (to have the other nice features like the label animation). Thanks.

Would a contribution to the docs about native distribution with flatpak be accepted? To even bother writing it or not 😛 It would allow to support tons of linux distros compared to the limited

.deb

currently allowed by jpackage. Adding a dedicated section for flatpak here: https://github.com/JetBrains/compose-jb/tree/master/tutorials/Native_distributions_and_local_execution

Hey, I currently can't use compose v1.1 because

Could not resolve org.jetbrains.skiko:skiko:0.7.16

. Is there some repository where that's available or do I have to wait for it to land in one? edit: (ahh maybe this is for #compose)

Does anyone know of a Crash reporting solution that supports proguard / mappings.txt for java?

Feeling a little lost on what to use for a Map of data that's manipulated in a non-compose module but reflected in the UI.

SnapshotStateMap

seems like the ideal way to expose it to the UI, but I can't use that in my non-compose module.

StateFlow<Map<T, V>>

seems like the only option, but that emits the entire map on each change, rather than only what changed about it. Any other better options? I could make a

SnapshotStateMap

observe the

StateFlow

but that's kinda gross, right?

Does

rememberSaveable

save and restore across app invocations on desktop? Specifically my window size is not being remembered on MacOs, which it seems it should be since

rememberWindowState

delegates to

rememberSaveable

.

❓ Is the need to notarize a DMG really a hard 'Apple' limitation for distributing Mac Apps beyond your local build machine? What makes me doubtful is that you frequently come across ad-hoc distributed Mac Apps in the wild; which refuse to run normally due to having not being signed; and yet you can still run them with 'Right Click -> Open' on the App, as a kind of 'confirmation' that you accept the risk. What makes CfD's packaging different? Could we not achieve the same experience? It's not ideal of course, but still very useful in many situations e.g. just wanting to share a utility App with colleagues.
