Main goal is: get content "xywh" from given rect and padding.
Of course content.x is dynamic.

//
import core.sys.windows.windows;
import std.stdio;


class Base
{
     RECT rect    = { 0, 0, 500, 400 };
     RECT padding = { 10, 10, 10, 10 };

     // ...content...
     ??? content
     {
          property int x() const { return rect.left + 
padding.left; }
     }
}

int main()
{
     auto b = new Base();
     writeln( b.content.x );
}



How to implement "b.content.x" ( sequence call "content" of the 
"b" and then "x" of that ) ?
How to implement beauty ?

Now working with this variant:

struct Content
{
     Base This;

     int  left()    { return This.rect.left   + This.padding.left; 
   }
     int  right()   { return This.rect.right  - 
This.padding.right;  }
     int  top()     { return This.rect.top    + This.padding.top;  
   }
     int  bottom()  { return This.rect.bottom - 
This.padding.bottom; }

     int  x()       { return left;         }
     int  y()       { return top;          }
     int  w()       { return right - left; }
     int  h()       { return bottom - top; }

     RECT rect()    { return This.rect; }
}


class Base
{
     RECT rect;
     RECT padding;

     Content content()
     {
         return Content( this );
     }
}
