title: Cannot change Button size and location, with eclipse RCP?
body: <p>I'm using eclipse RCP to develop a user interface. I created some buttons and I want to change their size and location.I used the methods setLocation() and setSize() but didn't get any result:</p>
  
  <pre><code>Composite top = new Composite(parent, SWT.NONE);
  GridLayout layout1 = new GridLayout(2, true);
  top.setLayout(layout1);
  Button buttonEdit = new Button(top, SWT.PUSH);
  buttonEdit.setText("Edit");
  buttonEdit.setLocation(10,10);
  buttonEdit.setSize(50, 20);
  </code></pre>
  
  <p>Any idea?
  Thanks a lot</p>
