ComboViewer, How can I get the selected item of a comboViewer?

I created a ComboViewer

    final ComboViewer comboViewer = new ComboViewer(shlFreeViews, SWT.NONE);
    final Combo combo = comboViewer.getCombo();
    combo.setVisibleItemCount(4);
    combo.setFont(SWTResourceManager.getFont("Segoe UI", 13, SWT.NORMAL));
    combo.setItems(new String[] {"5", "10", "15", "20"});
    combo.setBounds(356, 172, 126, 25);
    combo.setText("5");

The problem is that when I open the program I have to select a number of my comboviewer and then I have to use this number for do a simple addition. What the code to get the selected number of the comboviewer?

You can either add an ISelectionChangedListener to the ComboViewer to get notified when the selection changes, or you can get it manually. The procedure is the same:

StructuredSelection sel = (StructuredSelection) viewer.getSelection();
YourDataType element = (YourDataType) sel.getFirstElement();
