+Indicates how many levels the event can propagate. This member is protected and
+should typically only be set in the constructors of the derived classes. It
+may be temporarily changed by \helpref{StopPropagation}{wxeventstoppropagation} 
+and \helpref{ResumePropagation}{wxeventresumepropagation} and tested with 
+\helpref{ShouldPropagate}{wxeventshouldpropagate}.
+
+The initial value is set to either {\tt wxEVENT\_PROPAGATION\_NONE} (by
+default) meaning that the event shouldn't be propagated at all or to 
+{\tt wxEVENT\_PROPAGATION\_MAX} (for command events) meaning that it should be
+propagated as much as necessary.
+
+Any positive number means that the event should be propagated but no more than
+the given number of times. E.g. the propagation level may be set to $1$ to
+propagate the event to its parent only, but not to its grandparent.
