How to create a Treeview Content Provider?

Question

I want to create a Treeview for an Eclipse-Plugin.

I generated the Treeview with:

_viewer = new TreeViewer(parent,SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL | SWT.FULL_SELECTION); 
_viewer.setContentProvider(new ViewContentProvider());

_viewer.getTree().setHeaderVisible(true);
_viewer.getTree().setLinesVisible(true);
_viewer.setAutoExpandLevel(1);

TreeViewerColumn column = new TreeViewerColumn(_viewer, SWT.NONE);
column.getColumn().setText("Package / CCID");
column.getColumn().setWidth(120);
column.setLabelProvider(new ColumnLabelProvider(){

        @Override
        public String getText(Object element) {
            return "test";
        }
        }
);

column = new TreeViewerColumn(_viewer, SWT.NONE);
column.getColumn().setText("Stage");
column.getColumn().setWidth(100);
column.setLabelProvider(new ColumnLabelProvider(){

    public String getText(Object element) {
        return "test";
    }
});

Now I want to fill the Treeview with Data from DB2. DB2 contains a table with the name "Package" and a table with the name CCID.

At first I want to list all packages in the table. Then I want to expand the package and show all CCID´s for each package.

For example:

+ package 1
+ package 2
+ package 3

and expended:

- package 1
   ccid 1
   ccid 2
   ccid 3
- package 2
   ccid 54
   ccid 34
   ccid 23
- package 3
   ccid 32
   ccid 23
   ccid 23

Is there any idea to solve my problem?

It is not at all clear what you are having problems with. Have you read any tutorials [like this](http://www.eclipse.org/articles/Article-TreeViewer/TreeViewerArticle.htm) on TreeViewer? — greg-449, Aug 19 '14 at 12:48
Hey Greg, i have problems to expand a object. For example: I want to expand an created object. For example: In the tutorial I want to expand each book object and not only the subject. Do you have any idea? — JonnyBeton, Aug 20 '14 at 12:09
