Problem with importing interface with static class

sbeaupre · August 19, 2013, 10:36am

I am using Kotlin 0.6.33 and tried as a test to automatically convert following class https://github.com/robovm/robovm-sample-jfx-app/blob/master/src/main/java/org/robovm/sample/jfx/RoboVMJFXLauncher.java to Kotlin.

The result is as follows (which looks not perfect, but ok IMO) :

package sample

import javafx.application.Application

import org.robovm.cocoatouch.foundation.NSAutoreleasePool

import org.robovm.cocoatouch.foundation.NSDictionary

import org.robovm.cocoatouch.uikit.UIApplication

import org.robovm.cocoatouch.uikit.UIApplicationDelegate
public open class RoboVMJFXLauncher() : UIApplicationDelegate.Adapter() {

  public override fun didFinishLaunching(application: UIApplication?, launchOptions: NSDictionary<NSObject?, NSObject?>?): Boolean {

  var launchThread: Thread? = object : Thread() {

            public override fun run(): Unit {

                Application.launch(getJavaClass<RoboVMSampleJFXApp?>)

            }
  &nbsp;&nbsp;}
  &nbsp;&nbsp;launchThread?.setDaemon(true)
  &nbsp;&nbsp;launchThread?.start()
  &nbsp;&nbsp;return true

  }
  class object {

  public open fun main(args: Array<String?>?): Unit {

            System.setProperty(“glass.platform”, “ios”)

            System.setProperty(“prism.text”, “native”)

            var pool: NSAutoreleasePool? = NSAutoreleasePool()

            UIApplication.main(args, null, getJavaClass<RoboVMJFXLauncher?>)

            pool?.drain()

  }

  }

}

fun main(args: Array<String?>?) = RoboVMJFXLauncher.main(args)

But the whole file is indicated as an error in the IDE and I get following error when I try to compile the class.

As far as I can trace back the problem, it seems to be related to the import statement:

import org.robovm.cocoatouch.uikit.UIApplicationDelegate

Which is following interface: https://github.com/robovm/robovm/blob/master/cocoatouch/src/main/java/org/robovm/cocoatouch/uikit/UIApplicationDelegate.java

And extending the ‘Adapter’ static class in it.

Are there any known issues with static classes in interfaces and extending them?

regards,

Sven

Thank you for the report. This is a bug in reading annotations from java file. Unfortunatly, there isn't any workaround, so I'll write you here when we'll fix it.
