DSL inside Window constructor

[Divelix]

I just wanted to do the thing from #306 with Window, but it doesn't work this way as KWindow is a final class. How can I use ktx DSL inside class inherited from Window?

For example, this doesn't work:

class MyWindow(...) : Window(...), KWindow { ... }

This is because KWindow is a concrete class of a widget, while KTable (from the linked example) is an interface that adds the DSL. Windows are actually just fancy tables in LibGDX - if you look into the KWindow implementation, you'll see that it also implements the KTable interface:

@Scene2dDsl
class KWindow(title: String, skin: Skin, style: String) : Window(title, skin, style), KTable

Instead of extending KWindow, all you have to do is implement KTable to get access to the DSL. When in doubt, check out which interfaces are implemented by the KTX widget. You can basically copy-and-paste the class and go from there.
