Adding a panel container to PreferencePage in an Eclipse PDE project

Question

I use the class FieldEditorPreferencePageto create the settings page for my Eclipse plugin. I was able to add all the controls I need on the page, however there are several controls that I would like to group together with the panel.

Here is an example from the Eclipse documentation. However, there is no information on how the "Open Mode" panel was added to the page and how the controls were added.

    }
}

You can use RadioGroupFieldEditorto add a set of radio buttons surrounded by a Group control.

Sort of:

RadioGroupFieldEditor groupPref = new RadioGroupFieldEditor("preference key",
      "Group title message", 3, 
      new String[][] {
        {"radio 1 text", "preference value 1"}, 
        {"radio 2 text", "preference value 2"}, 
        {"radio 3 text", "preference value 3"}},
     getFieldEditorParent(), true /* use a group */);
addField(groupPref);
