Scala GUI using QT on linux / archlinux

hi.scala

//> using scala 3.3.1
//> using platform jvm

// docs say that QtJambi runs on jvm 8 or later. My system has jvm 21 installed.

// --- QT6 | UI toolkit configuration on linux / archlinux

//> using dep io.qtjambi:qtjambi:6.6.1
//> using dep io.qtjambi:qtjambi-native-linux-x64:6.6.1

// not strictly needed since the default search path includes this path,
// but let's make it explicit for now. It's where the native Qt libraries are looked for.

//> using javaProp java.library.path=/usr/lib

// --- end QT6

import io.qt.widgets.*;

@main
def helloWorldWindow(args: String*) = {
  println("hi")

  QApplication.initialize(args.toArray)

  QMessageBox.information(null, "QtJambi", "Hello World!")

  QApplication.shutdown()

  println("bye")
}

I'm surprised it works.

Specially since I really thought QtJambi was dead but looking at https://github.com/OmixVisualization/qtjambi it actually has activity and already is available to use with QT6 which I already have the libraries around in my system 🥳

Ran on scala-cli at the following version:

❯ scala-cli --version
Scala CLI version: 1.1.2
Scala version (default): 3.3.1

Save the file locally and run with:

❯ scala-cli run .

Output should be the following:

❯ scala-cli run .
Compiling project (Scala 3.3.1, JVM (system))
Compiled project (Scala 3.3.1, JVM (system))
hi
# window shows up here according to the above screenshot. After closing the next message appears.
bye

Even more crazy, I think you can run the scala-cli pointing directly to this gist url and it runs accordingly:

❯ scala-cli run https://gist.github.com/vascorsd/1ae097030f51da40007ab74505d148da
Compiling project (Scala 3.3.1, JVM (system))
Compiled project (Scala 3.3.1, JVM (system))
hi
bye

But I wouldn't recommend anyone doing that, since I can just change the gist to become malicious 😈
