CForm



Form implementation. To create a form you just need to derive it from this class, pass to this class newly created window and renderer and create and setup controls. You may read more in programming guide.

You can find more information in comments below. Overrided methods can be found in corresponding base class or interface.

Input handler control

This control main purpose is to handle forms which have custom(not platform standard ones) borders and caption area. It is usually have no rendarable area and its size is zero. But it receive form unhandled input to handle resizing by custom borders and moving by custom caption as well as minimazing, maximizing, and closing a form. And it is usually responsible for custom borders and caption area drawing also.
