All events raised by an object can be processed by only one event observer. So 
things are not simple.

You can create your own control by inheriting UserControl or UserContainer in 
gambas 1.9.x. Examples are located in the source code of the gb.form 
component.

In gambas 1.9.x, there is a class name "Watcher" that can watch a control, and 
raise events when something happens on it: Move, Resize, ...

Actually, embedding a form is mainly useful just when you want to... embed a 
form, and not when you want to use it exactly like a control.

Having many event observers for the same object is too complicated to do, but 
maybe I could implement a way to dispatch an event to another object, by 
having two event observers... I really have no real idea at the moment.
