GTK peers

I have done a fair amount of work on the AWT files. I have removed AWT 1.0 
specific methods (because they break compiles).

My question is about the GTK peers. I have managed to generate the header files 
for each .c files, and can run up to the point where an GTK frame is created 
with a title. (Mouse events also seem to be handled)

I cannot add any components to the frame because:

Recall that Frame extends Window extends Container

When addNotify is called on the Frame, it does:


This means, the addNotify method for Container is never called (it has been 

  if (is_notified)

  is_notified = true;
  Enumeration e = components.elements();
  while (e.hasMoreElements())

This means the is_notified member in Container is never set to true, which 
means the addImpl method will never create a peer for new components:

protected void
addImpl(Component component, Object constraints, int index)
  if (index == -1)
    components.insertElementAt(component, index);

  // Create peer if necessary
  if (is_notified)

What should I do? Should we make a method in the Container class that 
initializes it? We could call this from all subclasses of Container?
