Is it possible to set parent to JWindow after it was created?

Question

Is it possible to set parent to JWindow after it was created? For example:

public class SomeJWindow extends JWindow {

  public SomeJWindow (JFrame parent) {
      //super(parent); - parent not set yet.
    }

}

and later set parent to SomeJWindow.

Answer 1

not it isn't possible, because

• Top-Level Container is based on peer from Native OS, parent isn't possible to change, set after Top-Level Container is initialized

• not possible to delegate, change parent from one Top-Level Container to another

• I can't found any access to modify xxx$SharedOwnerFrame

• Top-Level Container haven't implementer finalize() in API, then its life_cycle ended with current JVM
