Maybe in fact the form* files need not to be targeted directly.


Here some locations in the code used by "gtk" that lead to
code-sequences that I think could be cleaned up to separate the message
queue code from the gui code.


gtkmsgque.pp 47:
   TGtkMessageQueue=class(TLinkList)          

defines the event queue object



gtkwinapi.inc 7402:
   function TGtkWidgetSet.PostMessage(Handle: HWND; Msg: Cardinal;
wParam: WParam;

here events are inserted into the queue


gtkwidgetset.inc 1204:
   procedure TGtkWidgetSet.AppProcessMessages;   

here we wait for events and events are taken out of the queue

gtkwidgetset.inc 1224:
   gtk_main_iteration_do(False); 



My suggestion includes that e.g.

 - the "MessageQueue" class is defined independently of the Widget Type
("Interface") as a simple ubiquitously usable object.using
inheritance/functions/properties/callbacks to interface whatever Widget
type specific code uses it.

 -  AppProcessMessages is defined in a file independent of the Widget
type and done way that is independent of the Widget type, interfacing
the Widget type actually used by inheritance/functions/properties/callbacks
