title: Layout problems in FieldEditorPreferencePage
body: <p>I have following problems with layout settings in the FieldEditorPreferencePage.<br>
  My code is something like this: </p>
  
  <pre><code>public void createFieldEditors () {
    Group pv = new group(getfieldEditorParent(), SWT.SHADOW_OUT);
    Group of = new group(getfieldEditorParent(), SWT.SHADOW_OUT);
    pv.setText(“pv”);
    of.setText(“of”);
    GridLayout layout = new GridLayout(2,false);
    pv.setLayout(layout);
    of.setLayout(layout);
    addField(new StringFieldEditor(“PreferenceStore name”,“Text:”, pv);
    addField(new StringFieldEditor(“PreferenceStore name”,“Text:”, pv);
    addField(new StringFieldEditor(“PreferenceStore name”,“Text:”, of);
    addField(new StringFieldEditor(“PreferenceStore name”,“Text:”, of);
    and so on.
   }
  </code></pre>
  
  <p>The problem is that it does not work with GridLayout.<br>
  The StringFieldEditors are not parallel. The number of columns is always 1. Also when I try to change the size of StringFieldEditors in the groups, it doesn’t work too.   </p>
  
  <p>Anybody have any ideas?<br>
  Thanks.</p>
