The Hello World view

Now that we've created a project, package, and view class for our plug-in, we're ready to study some code.  Here is everything you need in your HelloWorldView.  Copy the contents below into the class you created, replacing the auto-generated content. 

   package com.example.helloworld;

   import org.eclipse.swt.widgets.Composite;
   import org.eclipse.swt.widgets.Label;
   import org.eclipse.swt.SWT;
   import org.eclipse.ui.part.ViewPart;

   public class HelloWorldView extends ViewPart {
      Label label;
      public HelloWorldView() {
      }
      public void createPartControl(Composite parent) {
         label = new Label(parent, SWT.WRAP);
         label.setText("Hello World");
      }
      public void setFocus() {
         // set focus to my widget.  For a label, this doesn't
         // make much sense, but for more complex sets of widgets
         // you would decide which one gets the focus.
      }
   }

The view part creates the widgets that will represent it in the createPartControl method. In this example, we create an SWT label and set the "Hello World" text into it. This is about the simplest view that can be created.
