How to contribute to the Eclipse IDE from a model fragment

问题

I need to contribute a part (with a command and handler) to the eclipse IDE.

I'm using Eclipse RCP and RAP developers (Mars 4.5) and I don't know how to program my handler so my part goes to the editor of the eclipse ide.

My part contributor is something like this:

public class Menu extends ViewPart {

@PostConstruct
@Override
public void createPartControl(Composite parent) {
    parent.setLayout(null);

    Label lblService = new Label(parent, SWT.NONE);
    lblService.setBounds(67, 49, 40, 15);
    lblService.setText("Service:");

    Combo combo = new Combo(parent, SWT.NONE);
    combo.setBounds(112, 45, 213, 23);

    Label lblOperacion = new Label(parent, SWT.NONE);
    lblOperacion.setBounds(51, 97, 56, 15);
    lblOperacion.setText("Operation:");

    Combo combo_1 = new Combo(parent, SWT.NONE);
    combo_1.setBounds(112, 93, 214, 23);

    Label lblRequest = new Label(parent, SWT.NONE);
    lblRequest.setBounds(62, 145, 45, 15);
    lblRequest.setText("Request:");

    Combo combo_2 = new Combo(parent, SWT.NONE);
    combo_2.setBounds(112, 141, 213, 23);

    Button btnCommandButton = new Button(parent, SWT.NONE);
    btnCommandButton.setBounds(223, 189, 108, 25);
    btnCommandButton.setText("Command Button");     
}

@Override
public void setFocus() {
    // TODO Auto-generated method stub

}

I already know how to contribute to another aplication but not to the eclipse ide. If someone could help me or give me some ideas, maybe a web page with tutorial of this or something...

EDIT: ok, i found someone who ask almost the same question here:How to contribute a new view in eclipse 4.2?

No one give a solution beacuse of the bug, but now the bug its fixed in 4.5.

My plugin.xml:

<?xml version="1.0" encoding="UTF-8"?>
<plugin>
    <extension
         id="py.com.leverit.gepetto.services.tester.fragment"
         point="org.eclipse.e4.workbench.model">
      <fragment
            uri="fragment.e4xmi">
      </fragment>
   </extension>
</plugin>

My fragment.e4xmi:
