Changing the visibility of C/C++ fields and methods
You can change the visibility of C/C++ fields and methods directly
in a class diagram.
You must be in the C/C++ perspective and have a diagram open in the
diagram editor.
To change the visibility of a field or method, in the diagram
editor, right-click a C/C++ field or method; then click Visibility to
add the check mark beside the appropriate selection.
