  I want to implement the function that when I click a item form a list, then the related view will redraw and call the function 'createPartControl'.I konw the view's id.So how can I get to it?</p>
  
  <p>This is the view's <code>createPartControl()</code> method.</p>
  
  <pre class="lang-java prettyprint-override"><code>public void createPartControl(Composite parent) {
      // TODO Auto-generated method stub
      final List list = new List(parent, SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);
      final ObjDumpParser objdump = new  ObjDumpParser();
      List&lt;DisFunction&gt; funclist = objdump.getTextFunList();
      int funcNum = funclist.size();
      System.out.println("123: " + funcNum);
      for (int i = 0; i &lt; funcNum; i++){
          ......
  </code></pre>
