My goal is to create test class with  two CWndClient  members (two rectangles )  but in the  main file I'd like to be able to add this object to

CAppDialog as a single object and to be able  to use .Add Method      so those two members would be move with main window (mouse)  ...but I'm the beginner so there is a mistake in the code :) .

No errors but the only clsDialog is moving      ....im not testing "IF" correct   ..just trying to understand general idea  ....i found this article and is awesome https://www.mql5.com/en/articles/4503  but I'd  like to create separate class . if understand the concept like to create an objecte to be  able to add the to my future projects    ....this is just to learn the principle (2 Wnd objects as single class , and i can  .Add    this class  to CAppDialog)   ..is there article about this  ...or how to search in google for it ???

I believe this is because Panels and Dialogs classes of the Standard Library only provide a brief technical description of methods. The language reference...
