        });

        btnShow.setBounds(23, 146, 75, 25);
        btnShow.setText("Show");    

        shell.open();
        shell.layout();
        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }
    }
}

The StyledText setText method replaces all the existing text with the new text so you are only getting the last item.

Instead you can use the append method to add to the end of the control, so something like:

for (String item : list)
 {   
   styledText.append(item + '\n');  // Add item with new line between entries
 }
