Sorry for the dump of messages 🙂 All this hacking of the past few days led to a new demo: https://twitter.com/Piwai/status/1347334496442478592

still trying to wrap my head around compose for desktop i still have two concerns mainly related to the fact that it’s an port from an android framework • is there any table component? the best i could do was to use a

SwingPanel

to use the faithful

JTable

• how do you bind the tab key to jump to another field?

Is there any guidance to implementing modal dialogs? As far as I understand it should be part of the composition through the whole lifetime of the dialog, are there any established practices on doing so? Also, how do I disable interaction with the rest of the UI while the dialog is open? Similar question about popup windows – like floating tooltips, popup menus, dismissing when clicked outside, etc.

The most annoying thing for me now is

androidx.compose.material.Text

vs

androidx.compose.foundation.Text

🙂 Not that big deal, but since I use a lot of

Image

components, the foundation’s Text comes into place in almost every situation. Do you plan to bring some order into packages/components?

Another confusing piece is

imageResource

(composable with remember) vs

imageFromResource

(just creates ImageBitmap). In a composable context it’s easy to use the wrong one and cause excessive bitmap creations. Consider renaming one of them to be not so similar and making it more obvious from the name when to use which.

I’m trying to implement

backgroundImage

modifier like this:

@Composable
fun Modifier.backgroundImage(bitmap: ImageBitmap, contentScale: ContentScale = ContentScale.Crop): Modifier {
    val imagePainter = remember(bitmap) { ImagePainter(bitmap) }
    return paint(imagePainter, false, contentScale = contentScale)
}

But if I do it like this it doesn’t show any content. If I implement my own

DrawImageBackgroundModifier

with trivial draw using drawImage and drawContent, it works as expected. What I’m missing?

These all should go to #compose

I am trying to copy text to clipboard and access outside of compose app. Appears to be on the clipboard but I can't paste outside the compose app. Am I using the correct Clipboard code?

fun copyToClipboard(value: String) {

val c = Clipboard("")

val s = StringSelection(value)

c.setContents(s, s)

//Test

val stringValue = c.getData(DataFlavor.stringFlavor)

val data = c.getContents(null)

}

noobie here, how do I add a view or Composable to a state object, so I can basically pass in various views or composables

Hey everyone, for my Compose-Desktop app, I want to integrate with an API which makes use of an OIDC authorization code flow and therefor needs access to a browser session to complete successfully. Is there any form of support for browser session management (either through a webview, or even delegation to a system browser) for Compose-Desktop currently?

is ViewModel available for desktop? seems like its only adroidx

@ExperimentalLayout
@Composable
fun mainLayout(view: @Composable () -> Unit) {

    Row(Modifier.fillMaxSize()) {
        Box(modifier = Modifier.fillMaxWidth(0.2f), contentAlignment = Alignment.Center) {
            sideBarItems()
        }
        view()
    }
}

this works on first load, but when i call this from an onClick() event on those sidebar items I get an error about calling composable from an onclick()

Built a DMG and sent it to a friend but he said it seems like it's corrupted. Any ideas? Do I need to sign my code? Are there instructions for it, or any ways around signing it for just sending little dumb apps to a friend?

I am using Gradle

6.8

+ Kotlin

1.4.21-2

+ Compose

0.3.0-build13

+

OpenJDK15

and getting this weird error on compilation. Has anybody seen this error earlier? Haven't seen this issue with regular kotlin projects though.

Inspired by a very helpful comment by Roman Sedaikin (thanks again) to an issue I created on GitHub, I did a small post about AlertDialog and DesktopDialogProperties: https://dev.to/tkuenneth/customize-a-compose-for-desktop-alertdialog-a6e

Hi folks, is possible to use Compose for Desktop on a OpenGL application, example: I have a game writing in Kotlin using OpenGL and I want to do some GUI in Compose. I think that the currently Compose for Desktop is not possible, but using a Low Level API from Compose should be possible?

Hey! If I understand correctly, Compose Desktop uses https://github.com/JetBrains/skiko which in turn uses https://github.com/JetBrains/skija (a library that provides java bindings for https://skia.org/). And Skia is an actual rendering library. I’m asking because I recently contributed Skottie (https://skia.org/user/modules/skottie) bindings to Skija. If my understanding is correct then Compose Desktop doesn’t expose Skija in public API so it’s not possible to create a 3rd party library for playing Lottie animations. I’m thinking about contributing something similar to: http://airbnb.io/lottie/#/android-compose directly to Compose Desktop. But before I pull the Compose repo and start learning its tooling, I wanted to ask if you think it’s a good idea and if my understanding is correct.

👋 When I make a mistake and end up causing an exception in my compose code, it looks like the default handling is to just log it and keep going. Is that expected behavior? On Android the default behavior is to crash, and that’s kind of what I expected. Should I file a bug?

I would like to modularize my current Compose-Desktop project, but I'm not sure which type of modules I should choose (Java/Gradle/Kotlin/...) and I'm wondering if someone has a good example of what a

build.gradle.kts

file for a Compose-Desktop submodule would look like as well?

Made some more progress on SharkApp, sharing here if anyone’s looking for sample code that does some of these things: https://twitter.com/Piwai/status/1349070351108435968

An undecorated Compose for Desktop AlertDialog can be dragged around using good old Swing. Will be posting the short piece of code soon, this clip is to wet your appetite. 😂 The white bar at the bottom needs to be investigated, I think it might be a reproducible issue in Compose for Desktop. If so, will open an issue on GitHub

Hi. JB-Compose is pretty cool. I want to use it for an embedded linux project. Is there going to be a ARM 64-bit packaging target ?

I'm just working through the Jetpack Pathway using Desktop and ran into an issue with the Custom Layouts section. just thought i'd mention it here. [detail in comment]

Hey, I am trying to create a column containing rows to make a 3x3 grid of buttons that fill the window with all of them the same size. Is there some way to accomplish this? Thanks

is constraint layout on compose desktop? maybe i need to add a dependency but i'm unsure how and documentation is a little thin.

Can we minimize the app to the system tray?

Question to people considering using Compose for Desktop in their projects: job, commercial, hobby. How much it will affect you when we reach 1.0 version of Compose for Desktop in terms of ability to use the technology? Update: a bit rephrased question, to emphasize that we all want to reach 1.0, and question is mainly about how important the version for convincing other people. 1️⃣ - critical, blocker 2️⃣ - important, but not blocker 3️⃣ - not important, version is just a number
