java - Swing - how to handle multiple cross-dependent components? -

this more general question: have quite complicated files table in swing (the data model not trivial) , , when when user clicks on entry , 2 other view components need change - file statistics view , , file content view - both on same screen.

one options have these components class definitions in same file , , have reference each other - make messy code.

the other option think of pass statistics , content components table object , , have him use - render table not - reusable anywhere else.

i'm sure there's better way - recommend do?

option 1:

class mypanel extends jpanel{  private mytable table; private myfileviewer fv; private myfilestats stats;  class mytable {    addmouselistener({ ... fv.update(); stats.update(); }) } class myfileviewer{...} class myfilestats{...} } 

options 2:

class mytable {     mytable(myfileviewer fv, myfilestats stats) { ...         addmouselistener({fv.update, stats.update ... }     }     } 

option 3: model–view–controller pattern, discussed here , in this outline. mvc hinges on observer pattern. instead of having each view update others, arrange each view register listener data model. when model changes, each view updates accordingly.
