Calling to the owner class from a listener

Question

Having the follow class -

public class GUIclass1 extends org.eclipse.swt.widgets.Composite {
    private void initGUI() {

        {
            // The setting of the open file button.
            openButton = new Button(this, SWT.PUSH | SWT.CENTER);
            openButton.addSelectionListener(new SelectionAdapter() {
                public void widgetSelected(SelectionEvent evt) {
                    foo() ; 
                }
            });
        }
    }

    public void foo() {
        // implementation ..
    }
}

As you can see within the addSelectionListener there is a calling to method foo() .

My question is - which reference I should write as a prefix to foo() in order to know which class foo() related to .

I tried super().foo() with no success.

Answer 1

You would call it as GUIclass1.this.foo()
