Question

I wrote my first console app in Scala, and I wrote my first Swing app in Scala — in case of the latter, the entry point is top method in my object extending SimpleSwingApplication.

However I would like to still go through main method, and from there call top — or perform other equivalent actions (like creating a window and “running” it).

How to do it?

Just in case if you are curious why, the GUI is optional, so I would like to parse the command line arguments and then decide to show (or not) the app window.

If you have something like:

object MySimpleApp extends SimpleSwingApplication {
  // ...
}

You can just call MySimpleApp.main to start it from the console. A main method is added when you mix SimpleSwingApplication trait. Have a look at the scaladoc.
