In SWT_AWT:

/**
* Creates a new <code>Shell</code>. This Shell is the root for
* the SWT widgets that will be embedded within the AWT canvas.
*
* @param display the display for the new Shell
* @param parent the parent <code>java.awt.Canvas</code> of the new Shell
* @return a <code>Shell</code> to be the parent of the embedded SWT widgets
*
* @exception IllegalArgumentException <ul>
* <li>ERROR_NULL_ARGUMENT - if the display is null</li>
* <li>ERROR_NULL_ARGUMENT - if the parent is null</li>
* </ul>
*
* @since 3.0
*/
public static Shell new_Shell (final Display display, final Canvas parent)

The SWT widgets are created as children of the Shell returned by this
method. Shell.getChildren() can be used to walk the child tree.

Given a Swing Canvas, I do not think that there is a way to find an
associated SWT Shell.

i was interested in the other way:

given a Composite - how do you use Composite.getChildren to find the
swing Frame created with SWT_AWT.newFrame(Composite)? I have an menu
action to pass to a (swing) Editor - and the hooks are there to find the
active editor and its Composite - can i walk down Composite.getChildren?
it looks like i can find the "embedded" component with
Composite.getStyle - can i get the Frame from the embedded component?
for now, i just tagged the editor with an interface that saves off the
frame - and i moved on.

thanks for taking the time to respond-
