Can compose be used on arbitrary trees now?

[shikasd]

Yep, definitely
Leland tweeted about it some time ago with an example: https://twitter.com/intelligibabble/status/1273339533891788800

[Dominaezzz]

I tried it but Android Studio couldn't find those classes. AbstractApplier

[shikasd]

Maybe you don't have runtime connected as a dependency?

I also did an experiment with having a custom tree on server representing client UI

I want to experiment with JavaFX and see how well they can play together.

[Dominaezzz]

Did you get that working outside Android Studio?

[shikasd]

yep, definitely
I know that desktop variant of runtime is working with Swing as of now, so you could check that, I think

[Dominaezzz]

Woah! Swing has been done already?! Where can I find this?

maybe something like this?

[Dominaezzz]

Ah, interesting. Thanks!

A note for JavaFX is that the composer is not multi-thread-safe yet. That is only one composition can be running at a time so you are limited to safely performing the compositions on the main thread.

This is changing but is a limitation for at least until dev18.

[Dominaezzz]

Will keep that in mind.

[Dominaezzz]

I currently have this.

repositories {
    google()
    mavenCentral()
    jcenter()
    maven("<https://dl.bintray.com/kotlin/kotlin-eap>")
}

val composeVersion = "0.1.0-dev16"

dependencies {
    implementation("androidx.compose.runtime:runtime:$composeVersion")
    implementation("androidx.compose.runtime:runtime-dispatch:$composeVersion")

//    implementation("androidx.compose:compose-runtime:$composeVersion")
//    implementation("androidx.compose:compose-dispatch:$composeVersion")

    kotlinCompilerPluginClasspath("androidx.compose:compose-compiler:$composeVersion")

    testImplementation(kotlin("test-junit"))
}

But the compose dependencies are not being resolved.

[shikasd]

Hey, I imagine the difference here is that compose is published as a desktop flavour of mpp, so maybe you'll have to match this when consuming deps?

[Dominaezzz]

oh, I didn't consider that.

[Dominaezzz]

I just looked at the google maven repo and the artefact is .aar instead of .jar ..... rip.

[shikasd]

Yeah, but the desktop one should be jar, no?
Maybe it is not published at all, so consider building it yourself 🙂
