Important message in the release notes: "JavaFX 20 is compiled with --release 17 and thus requires JDK 17 or later in order to run. If you attempt to run with an older JDK, the Java launcher will exit with an error message indicating that the javafx.base module cannot be read."

JavaFX 17 requires at JDK 11 or later (release notes), so the short answer is that you can't do this.

JavaFX has been open-sourced after Oracle dropped it, and it's still in active development (they just released version 19 a month ago, see https://openjfx.io and https://github.com/openjdk/jfx). Also Gluon (https://gluonhq.com) made the toolchain to compile it into native apps for Linux, macOS, Windows, Android & iOS. So with now WebFX compiling it to the web, you get a fully cross-platform UI toolkit that lets you target all major platforms (Desktops, Web, Tablets & Mobiles) from a single Java code base. That's why I think it is interesting, especially for Java developers.

So, to add file associations, we need to be able to pass both the .properties file and the --file-associations option. At the time of writing this article, the org.jetbrains.compose plugin doesn't provide such a mechanism. There is an open issue on GitHub that describes a possible workaround, which, unfortunately seems to not work on macOS.

JetBrains has a simplified example of a general-purpose Compose text viewer here: https://github.com/JetBrains/compose-multiplatform/blob/master/examples/codeviewer/shared/src/commonMain/kotlin/org/jetbrains/codeviewer/ui/editor/Editor.kt


Compose for desktop has a scrollbar component available. You probably can't use that directly on Android, but you could probably steal most of its code.

My company uses https://github.com/JetBrains/compose-multiplatform to make a desktop app in Kotlin. It's amazing and fantastic. It's basically as mature as using Kotlin in an Android app.

Kamel is an asynchronous media loading library for Compose Multiplatform.

Kotlin Compose Multiplatform is the way to do Desktop apps. https://github.com/JetBrains/compose-multiplatform

As for missing controls, a common one is a grid. They have built in grids, but again they are built for Android and don't make any sense in a desktop app. There is no simple way to create an Excel-like Data Grid like you might see in Windows Forms, although it can be done. https://github.com/JetBrains/compose-multiplatform/issues/344.
