I want to embed a java.awt.Frame in a Embedded widget and then set that
widget as disabled. According to books and articles I've read I am
supposed to be able to listen to the parent and receive all the events
raised in the child. Keyboard events are the ones I am mostly
interested in (mainly because mouse events work in my case).

I am using eclipse 3.1 M4.

I used the following code to embed a java.awt.Frame in and RCP app.

> parent=new Composite(comp, SWT.EMBEDDED | SWT.NO_BACKGROUND);
> parent.setEnabled(false);
> SWT_AWT.new_Frame(parent).add(this); //the this object is a
>java.awt.Canvas
> parent=comp;

This is a fragment from the constructor of a implementation of
java.awt.Canvas.

When the canvas object has been created the keyboard events do not seem
to be processed. Eclipse commands are not processed and if I put a key
listener on comp no keyboard events are received.

However if I switch to another window then back to the app the keyboard
events are processed correctly.

I've attached an example where I'm attempting to reproduce the
behaviour. but it is not working correctly. In the view I've named
"view that accepts keyboard event" mouse events work but it seems to me
that keyboard events should work as well. In the other view no events
are being handled and I don't know why.
