Oh ok. I wasn't aware you could do it like that with an abstract class. 
I thought I had to "extend" my class to 'EmbeddedSwingComposite' since 
it was abstract (or make it non abstract). I'm still a student, so sorry 
for the newbiness :)

I went off of your snippet you posted (the one with the JTables) and 
also your Eclipse article and i'm apparently doing something wrong still.


In the old code, we put the canvas onto a JFrame.

Am I missing a function call?
What do I do with the returned JComponent of createSwingComponent()?
Should I be returning the frame instead of the canvas?


So the code i used was:
.
.
.
SashForm sf = new SashForm(main_shell, SWT.VERTICAL);
sf.setLayoutData(new GridData(SWT.FILL,SWT.FILL, true,true));

	
Composite swing_composite = new Composite(sf, SWT.EMBEDDED | 
SWT.NO_BACKGROUND); // put this composite as the top portion of the sashform

createPartControl(swing_composite);
setFocus();

.
.
.

then my function that I went off of your snippet example:

public void createPartControl(Composite parent) {
    embeddedComposite = new EmbeddedSwingComposite(parent, SWT.NONE) {
        protected JComponent createSwingComponent() {
            /* Creating components */
        	JFrame frame = new JFrame();
        	canvas = new NetCanvas(frame);
        	canvas.setBackground( Color.BLACK );
        	canvas.setBounds( frame.getBounds() );
        	canvas.setDoubleBuffered( false );
		
            return canvas;
        }//end createSwingComponent
    };
    embeddedComposite.populate();
}//end

public void setFocus() {
    embeddedComposite.setFocus();
}
