+The == and != operators of @ref overview_refcount_list "the reference counted classes"

Note that wxWidgets follows the <em>STL philosophy</em>: when a comparison
operator can not be implemented efficiently (like for e.g. wxImage's ==
Note that the list above reports the objects which are reference counted in all
ports of wxWidgets; some ports may use this technique also for other classes.
-All the objects implement a function IsOk() to test if they are referencing valid

+All the objects implement a function @b IsOk() to test if they are referencing valid

trying to call any other getter, e.g. wxBrush::GetStyle() on the ::wxNullBrush object,
will result in an assert failure in debug builds.

that the modifications won't affect other instances which are eventually
sharing your object's data.
