title: What is the wxWidgets equivalent of a C# User Control
body: <p>I am currently designing the migration of my existing .NET / C# / WinForms project to a platform neutral solution and the most attractive alternative I have seen seems to be wxWidgets especially taking in consideration my familiarity with C++ and with MFC that appears to have a lot in common with it.</p>
  
  <p>After going though the documentation and the sample code I need to clarify the following issue:</p>
  
  <p>Is it a valid assumption that the way to develop a User Control (by C# terminology) in a wx environment is to derive a class from wxPanel , customize it and place it in a wxFrame?
   If this is the case what is the wxFrame method to be used to add the wxPanel object to it ?  </p>
  
  <p>The only relative method I was able to find was wxWindow::AddChild but the documentation states that is mostly internal to wxWidgets and shouldn't be called by the user code.</p>
  
  <p>To avoid confusion please note that my question is about a User Control and not a Custom Control (which is clearly addressed in the documentation)  </p>
