Am I approaching the problem correctly (Java class organization)?

Question

Java

Hello everyone, tell me if I'm approaching the solution of the problem correctly?
There is a left menu that can be FULLSIZE (text + icons + crap) and MINISIZE (icons)
I do have a main class (container) and nested blocks (inner classes), in one of the inner blocks there is a "Resize" button.
Pseudocode:

//Главный класс, контейнер для вложенных блоков
class LeftMenu  {
     Logo logo;
     Menu menu;
     LeftMenu context;
     //Конструктор
      {
       this.context = this;
       setWidth(200px)
      
       logo = new Logo(); //Блок логотипа
       menu = new Menu(); //Само меню
       addComponent(logo,menu)
     }

     void changeSize(){
         logo.changeSize();
         menu.changeSize()
      }

    //Внутренние классы   
    class Logo implement ResizeInterface{
        ......
       Button btnChangeWidth = new Button();
       btnChangeWidth.addOnClickListener(e->context.changeSize())//Метод основного класса
      @override
       void changeSize(){
         setWidth(50px)
       }
    } 

    class Menu implement ResizeInterface{
        ......

      @override
       void changeSize(){
         setWidth(50px)
       }
    } 
}

Overall, it looks reasonable.

1. The Logo and Menu classes can be placed in separate files - this will help you not to get lost in the code in the future (when there are a lot of classes and it turns out that there is more than one class in one file, you start to get lost)
   
2. Not very clear from the code
   

   {
          context = this;
          setWidth(200px)
         
          logo = new Logo(); //Блок логотипа
          menu = new Menu(); //Само меню
          addComponent(logo,menu)
        }

   
   What is context and where is the addComponent, setWidth method declared . If you didn't cut anything out of the code when you posted it here, then it's not clear how it works for you
