Problem setting focus for a newly added child element in TreeViewer

[b gorle]

Hi

My treeviewer contains both parent and child elements. When I am trying to add a new child element for a particular parent element, some how the focus is getting lost. My code goes like this

protected void setSelectionToViewer(final Collection theSelection)

{

if (theSelection != null && !theSelection.isEmpty())

{

// Try to select the items in the current content viewer of the editor.

Object[] asArray = theSelection.toArray();

if (collectionViewer != null && asArray != null

&& asArray.length > 0 && asArray[0] != null)

{

collectionViewer.getViewer().reveal(asArray[0]);

collectionViewer.getViewer().setSelection(new StructuredSelection(asArray), true);

collectionViewer.getViewer().getControl().setFocus();

//myTreeViewer.getControl().setFocus();

}

}

}

Any help is highly appreciated. Thanks in advances bgorle.

quick quiz for you:
which is easier to read, in the way you're used to seeing it

1)
class FirstProgram
{
public static void main(String[] args)
{
System.out.println("Hello World");
}
}

or
2)

class FirstProgram
{
public static void main(String[] args)
{
System.out.println("Hello World");
}
}

or
3)

    
class FirstProgram
{
  public static void main(String[] args)
  {
    System.out.println("Hello World");
  }
}

Sorry for that!! Please check it now. Also if you are unable to understand below code please suggest what is the general procedure to set Focus for a newly added child element in a treeview. When I add an element, the focus should be on the newly added element, but for some reason i am unable to set the focus and it is lost ...

protected void setSelectionToViewer(final Collection theSelection)    
{    
if (theSelection != null && !theSelection.isEmpty())    
     {    
  
       // Try to select the items in the current content viewer of the editor.    
          Object[] asArray = theSelection.toArray();    
           if (collectionViewer != null && asArray != null  && asArray.length > 0 && asArray[0] != null)    
                {    
                collectionViewer.getViewer().reveal(asArray[0]);    
                collectionViewer.getViewer().setSelection(new StructuredSelection(asArray), true);    
               collectionViewer.getViewer().getControl().setFocus();    
               //myTreeViewer.getControl().setFocus();    
                }    
      }    
}
