display a text in a view and edit it

I've added a view to my plugin and I want to first, read and display a file content and second, have the possibility to modify the content . In other w开发者_开发知识库ords I want to have an editable zone in my view , a sort of an editor . I didn't know what steps to follow to implement my class . here is the class :

public class LabelView extends ViewPart {
 private Label label;


 public LabelView() {
  super();
 }

 public void setFocus() {
  label.setFocus();
 }

 public void createPartControl(Composite parent) {
  label = new Label(parent, 0);
 }
}

thank you so much for your help

Create a Text object in the parent composite would be the simplest way.
