org.eclipse.swt.widgets.Composite setSize not working properly

I'm currently developing a custom plugin and I don't quite understand why a Composite element takes all the space even if other Composite elements are present.

My Handler for the execution of the plugin goes like this:

public class IwokGeneratorHandler extends AbstractHandler {

    @Override
    public Object execute(ExecutionEvent event) throws ExecutionException {

        IWorkbenchWindow window = HandlerUtil.getActiveWorkbenchWindowChecked(event);
        Shell shell = window.getShell();
        ApplicationWindow win = new ApplicationWindow(shell) {

            @Override
            protected Control createContents(Composite parent) {

                parent.setSize(800, 600);
                //first panel
                Composite composite = new Composite(parent, SWT.NONE);
                //x, y, width, height
                composite.setBounds(10, 10, 424, 70);

                //second panel
                Composite composite_1 = new Composite(parent, SWT.NONE);
                composite_1.setBounds(10, 86, 424, 309);

                //third panel
                Composite composite_2 = new Composite(parent, SWT.NONE);
                composite_2.setBounds(10, 407, 424, 42);

                return parent;
            }
        };
        win.open();
        return null;
    }
}

However, the first Composite takes all the space of the main Application window and the others cannot be seen, whatever the window size it is. I checked it multiple times.

Is there any property I'm missing to prevent elements to autifill?

Thank you in advance

ApplicationWindow expects the createContents method to return a single Composite containing all the controls in the content (as do most other JFace window and dialog classes).

So something like:

  protected Control createContents(final Composite parent) {

      parent.setSize(800, 600);

      // Main body composite
      Composite body = new Composite(parent, SWT.NONE);

      //first panel
      Composite composite = new Composite(body, SWT.NONE);
      //x, y, width, height
      composite.setBounds(10, 10, 424, 70);

      //second panel
      Composite composite_1 = new Composite(body, SWT.NONE);
      composite_1.setBounds(10, 86, 424, 309);

      //third panel
      Composite composite_2 = new Composite(body, SWT.NONE);
      composite_2.setBounds(10, 407, 424, 42);

      // Return the body
      return body;
  }

Note that your code is also returning parent which is wrong - it must be the created composite.

Note: Although using setBounds may look simple to start with it will cause problems if the code runs on different machines with different font sizes (or control sizes if you run on macOS/Linux/Windows). Using Layouts is strongly recommended.
