- @class wxWeakRefDynamic
-
wxWeakRefDynamic<T> is a template class for weak references that is used in
the same way as wxWeakRef<T>. The only difference is that wxWeakRefDynamic
defaults to using @c dynamic_cast for establishing the object reference
is to handle objects which derived type one does not know.
@note wxWeakRef<T> selects an implementation based on the static type of T.
- If T does not have wxTrackable statically, it defaults to to a mixed-
+ If T does not have wxTrackable statically, it defaults to a mixed-
mode operation, where it uses @c dynamic_cast as the last measure
(if available from the compiler and enabled when building wxWidgets).
